How to Grow Broccoli-Kale Mix Microgreens

[@minhmansgu]

Hi Sir, so I watched some videos of your channel and realized the IHG method is really awesome. We can reduce the cost of medium, but we need to add more the water cost. Did you find out the ratio between using how much of water in IHG method from the different one? I really appreciate.

[@C3Voyage]

Great question. IHG uses exactly what the microgreens need because they are bottom-watered from the reservoir below. The reservoir is also covered so there's little evaporation. I've done water-use tests and each grow uses 2-4 gallons for the entire grow, seed-to-harvest. Sunflowers will use more than broccoli for example. I can't see how another other way would conserve more water. My older grows, like this one, is me learning towards how I do it now IHG.

[@tangobayus]

You might keep in mind that during the vegetative phase plants just need blue light. The red light from the special growing LED's goes to waste. 6500K is best for vegetative. Lowe's carries 6500K in both T12 and T8. You can lower your capital costs by avoiding the expensive lights when you are growing greens. The plants do not get leggy when grown under blue lights. From watching your videos I get a sense that the warmth of your greenhouse is contributing a lot to the abundant growth of your microgreens.

[@C3Voyage]

Hey Tango, yes I'm aware of that and you're 100% correct. The LEDs I have are for indoor gardening during the winter. It's the fruits I'm after--tomato, squash, cucumber, and more. Micros are pretty new to me, but I will supplement with micros for sure from now on in the winter only probably. In the micros area, I will go to white light LEDs only on both shelves. Micros actually don't need much light, even white LEDs to green up so that's in the works. I've been speaking with and researching all of that as well. It'll allow me to better manage the other LEDs as well. Just some follow-up with you to let you know I'm learning and hopefully I'll get better. :O)

[@markm2302]

You sound like you have a lot of experience. Do you use a soil for microgreens? Do you use lights the entire time?

[@YankeeinSC1]

Brent, thanks. You're infectious. This is something I only had a minor interest in, but my desire to continue on a 100% plant based diet for health reasons, always has me always looking for variety. Introducing interesting changes like ethnic recipes and micro greens helps keep me motivated. Your educational videos (not to mention your occasional goofy laugh), have sucked me into growing a few containers of micros at home. Just had a salad that included my first harvest of radish sprouts and some sprouted sweet peas.

[@C3Voyage]

I'm taking that as a raving compliment YankeeSC! You made me laugh and I shared with the wife too. :O) I have diabetes and it's a big reason I got into them. Look for a book on my style of growing if you're so inclined. All the best, eat healthier, and get out and enjoy the small things in life. Happiness is a choice!

[@carolinehonse35]

I really love your videos. They are so helpful, interesting, and friendly to all levels of microgardeners. Also,, I love that you show, in detail, what experiments worked and those that didn't. You may call yourself "also a newbie" but those are the traits of a master gardener.

[@C3Voyage]

Wow, thanks so much Caroline! Sure appreciate the comments.

[@lynkpaul2171]

Thank you for this, it's an excellent way to start up micro greens and clean too. For those who do not have money to put out for soil.

[@C3Voyage]

Thanks Lynk. Appreciate the kind words.

[@carolhudson1194]

I'm using coconut fibre matting as a medium to grow my micro greens. I will let you know how it works out for me.

[@C3Voyage]

Great. :O)

[@KODArunner]

Great video, I learned a bunch! Here is my take on harvesting: instead of cutting the micro-greens from the screen, maybe try and use a scraper to remove them. This would do two things, first you would harvest more and second you would not have so much to clean from the screen in final cleanup.

[@C3Voyage]

Definitely makes sense Richard. Good advice. Will try it in the future. :O)

[@StevieWonders2020]

you can also use dehydrator silicone fine screens. Easy to clean.

[@C3Voyage]

I've tried it before and it works, but the best option I've found is what I'm using today--food-grade poly. It's a little stiffer than silicone and I have it in two sizes to cover all micros including very tiny seed which you can't get with silicone.

[@JtJt-bg8rn]

Fantastic , thank you. Do they not need nutrients? Would love to do this but was going to use soil.

[@C3Voyage]

I wrote a book on this about a year after this video. It's been a year since the book was written now and I'm on the 2nd generation "Assemblies". I sell those. If you're interested, I'm taking orders and will begin production by 1 May. Alternatively, I should have a 2nd edition book out by Fall that'll have build directions along with how I grow in my style IHG. My email is in the description of every video.

[@TheGhostchaser8]

Very interesting indeed sir. Can I ask where you purchased your trays?

[@C3Voyage]

You bet. I have a link in the description.

[@carolinablonde88]

Thanks for detailing your failed attempts too. That helps just as much as success stories. I've been looking into no medium microgreen/fodder for my livestock and my family. I'm binge watching your videos now. Got yourself a new subscriber :)

[@C3Voyage]

Awesome CB! Welcome. :O)

[@studentofself881]

Hello, I really enjoyed your video. I am interested in growing micro greens and I too thought it would be great to grow without soil. Can you share what exactly what you are using in the water to nourish your greens?

[@C3Voyage]

Masterblend formula. Look up "nutrients" on my channel. I believe there is a video on it.

[@ismailtulcali]

Thank you for your helpful and interesting videos. If you scrape the roots with a knife or something like that from the bottom and then harvest the product later, it seems easier to clean the remainings.

[@C3Voyage]

That surely makes sense. They'd pull out easier.

[@kathynix6552]

A dough scraper would work

[@TheLindsayschmidt]

I'm really enjoying all of your videos! Thanks again for making these! I love seeing all of the experimentation! If you are still looking for a food safe screen option (I heard you mention this in another video), you could try plastic canvas used for cross stitching. I believe the one made by Darice is food safe #5 plastic. There are different options for mesh size, depending on the size of your seeds. Have a fantastic day!

[@C3Voyage]

I actually have one. I couldn't find any that said food-safe though. I was going to use it, but someone just turned me on to a "roll" of food-save dehydrator screen which is what I used on the latest grows. This one will fit the whole tray though. I hope it works out. More to come Lindsay and thank you so much for the suggestion!

[@TheLindsayschmidt]

@@C3Voyage oh, that sounds like it would be an even better option! Is the dehydrator mesh small enough to keep broccoli seeds from falling through?

[@C3Voyage]

@@TheLindsayschmidt The one I'm using now was almost small enough for the Amaranth seed so yes on brassicas. The newest option I'm looking into is 1/8" and I'm not quite sure yet. I'll do a brassica grow on it once I get it.

[@TheMrJoeMac]

Very nice. I love growing Brocilli. I am about to grow Kale for the first time this week. You have some great videos. Appreciate you sharing.

[@C3Voyage]

Thank you Joe! Share a pic or two on FB if you like ok. I hope you rock the MGs.

[@DBCVC]

Hi Brent! Right on!! Perfect video for showing "No Medium/Substrate" !

[@C3Voyage]

Thanks DC! :O) I kind of thought the screen might be a substrate, but I left it alone because it can be easily cleaned and re-used kind of like a tray in that way.

[@harvestofpeace.therese]

Thanks! I bought some screen and am going to try this! What is the watering process? I have tried bottom watering with mixed results. Often I just get nasty smells which likely means too much water, not enough air.

[@C3Voyage]

At this time I just added nutrient-water and bottom fed. I've got a .pdf if you want the process for this grow. Email me.

[@harvestofpeace.therese]

@@C3Voyage Thanks, email just sent!

[@highway1052]

Been trying to grow microgreens without medium for some time, but fall victim to mold most of the time. What you have shown here looks promising. The water drains off the seeds but is available to the roots, with a small air gap. Must try immediately.

[@C3Voyage]

Sure true, but you're missing parts of it for how I do it now. I have a video coming out very soon where I talk about mold.

[@freestylefarming8881]

Sir...May I inquire as to where you get your trays from? I like the holes in those for what I am going to attempt! Thanks, Chuck.

[@C3Voyage]

Bootstrap Farmer is the name of the company. I bought the the mesh, the solid, and the 72-cell versions from Amazon. They also have a website.

[@BootstrapFarmer]

Great video Brent. Looks like you are getting some great use out of those trays. Loved the screen idea!

[@C3Voyage]

Hey BF! I didn't expect a visit from my "Tray Person". :O) I am loving your trays and they've really helped me with the microgreens and now preparing for Spring planting. You should make me some small-holled screened trays so small seeds don't fall through. Getting lots of interest in your trays here and on Facebook. Great product. All the best.

[@C3Voyage]

Another idea would be 1020 inserts for combined batch microgreens for personal use. Did a video on that recently. Say 5x5, 2.5 x 5, and 5x10 for example. Selfish wish over here. :O)

[@BootstrapFarmer]

Thanks for the ideas! 5x5 trays are already in the works. We are in the middle of production of those. We are hoping to have them ready late June - earl July. We recently started offering 10x10 trays.

[@C3Voyage]

I'll look for them.

[@charleskiplinger9904]

That looks like a good combination taste wise. Have to try the screen material. Have started out using jute burlap for the smaller seeds. Seems to work OK, but do think the screen will be better. Thanks Brent.

[@C3Voyage]

Hey Charles, my only experience is with the screen and it's working great with all I've tried...lettuce, broccoli, and kale. I'm quite certain it'll work with any small seed. Bigger seed, I wouldn't use anything but the tray because the roots could wallow out the screen and ruin it.

[@joelhenry4643]

Where did you get the trays with tiny holes? Gorgeous product. Great tips on ligtting, thanks

[@C3Voyage]

Bootstrap Farmer! They have a website and are on Amazon as well. Thanks!

[@clarionthechronicle7268]

I love Kale I love broccoli and i love that screen idea. Could just hang up the screen when your done and let dry for a couple days roots probably just fall off then Thanks for video

[@C3Voyage]

Sure can if you don't need it sooner.

[@EarthlyJewelsTV]

Hi where can i find out what nutrient is used for the solution? Where can i get some?

[@C3Voyage]

In the description of this video, click "see more" to open it up fully. Go down to "My Amazon Store" and click on it. The nutrient is called Masterblend and it's the 3rd item on top.

[@TNRVG]

Are you replacing the water at all or just put water in bottom and spraying? Change water when going to new plant.

[@C3Voyage]

If the water in the bottom tray needs it, I certainly change it. I look for clarity and smell it regularly. So, from the beginning. I put a little at the start of the grow for humidity. Later, as roots grow down, I increase the nutrient-water. As plants drink it all, I add more. I think at this point, I was rinsing outside?? I don't do that anymore for most grows. About changing water, every grow gets a fresh start with fresh nutrient-water.

[@TNRVG]

@@C3Voyage Thanks! I may be trying this myself or something similar.

[@malarkian]

Do these get the same antifungal treatment? How do you deal with brassica micros damping off?

[@C3Voyage]

Yes, I use the same AF spray on all of the micros. Using it and growing like you see in the video seems to prevent damping off as well as keeping the humidity down in the grow room along with fans.

[@bryanst.martin7134]

Great video. One word of caution, sanitize between harvests. Easy clean up doesn't prevent contagion. With 6 of those you could feed your family in desperate times. Nice setup.

[@C3Voyage]

Thank you Bryan for the kind words and the words of caution. Well received and noted, sir!

[@cybersecretary]

I thought of a screen too. I will now try it as you were very successful

[@C3Voyage]

Awesome. Best wishes.

[@RubberBand03]

How often do u water the seeds during germination?

[@C3Voyage]

It's bottom watering from day 1, but an antifungal is used until they come out of blackout. The primary ingredient in the antifungal is water. This was 2+ years ago.

[@eddysgreenhousegarden7022]

Brent, I am going to have to try that. Looks pretty easy and the results look really good. Thanks for showing that. Ed

[@C3Voyage]

You bet. Video it and I'll watch it Ed.

[@fastteddy6659]

You might try using a small squeegee to clean the screen. Are the MG's for personal use? How well do they keep, because it looks like a lot for a small family? I'd like to try them, but would perhaps scale down the amount. Thank you for sharing!

[@C3Voyage]

Squeegee, a great choice Teddy! Would grab a bit more I think. Yes, MGs for personal use and YT videos. We do bread, soup, and salad. It is too much for Gina and I in one sitting although they do last a while in the fridge actually. For the very reason you mention, I'm doing a "personal use" MG grow now. It's about half done and all growing in one flat. I hope it works out and I can share it. If it does, do one a week or even every two weeks and we'd be good! Hang in for that upcoming video.

[@fastteddy6659]

Thanks, Brent. Looking forward to a one tray mix. Seems a mix of things with similar growth habit, but each with its own section of tray might be one way. Then, if one section had a problem it could be treated without affecting the others, whereas if you mixed the seeds together and one species had troubles, the whole batch would be compost?

[@C3Voyage]

You're train of thought is similar to mine, but I'm seeding on different days since they're all fairly close.

[@tangobayus]

You can grow 2-3 different microgreens in one tray. I've heard they keep pretty well, but mainly you harvest them as you need them. Once they are grown they will be OK in dim light. Just keep them from wilting.

[@C3Voyage]

See latest video! Lol

[@amayaelessar]

Brilliant using the screen

[@C3Voyage]

Thank you Pur!

[@nathanrogers8713]

May have to do more trials for some media free grows. I am setting up tests now for automated bottom watering and some using inexpensive burlap. I grow and sell microgreens at a local farmers market and cutting costs would be good. I will say I use a good sharp knife for harvesting and it goes far faster and cleaner than a pair of scissors. I can crop out a full tray in under a minute of pretty much any type of microgreen.

[@C3Voyage]

I totally can see how doing it commercially you'd want to expedite processing. That's not a concern for me doing them for personal use. I've spent the majority of time babying them to harvest time, I don't mind a little extra time. In fact, I'm considering keeping them in the fridge for days in the trays for longer-term micro harvests. The cold and lack of light should slow them down to nothing, but keep them alive. On growing them overall, I can't see doing anything but no-medium/substrate even if I went commercial. Why would anyone? I would recommend letting go of the paradigm and it looks like you're attempting that with trial grows. All the best to you Nathan.

[@bonniebowers4603]

I saw a guy who sells to restaurants and delivers them with the rock wool medium still attached. but that may be different

[@GEOsustainable]

How many of those screens do you have 'just laying around'? It looks expensive if you are trying to start a business.

[@C3Voyage]

Uh, I guess that's relative to each person isn't it? I probably have 20-30 of different sizes, and since I have the material for my business sales, the capability to make much more. I sell them for $7 medium and $8 small right now. I just finished broccoli for 22.5 ounces. Video goes up shortly. One grow in sales pays not only for a couple screens, but potentially the whole kit. I have a small business I started after I retired from the Air Force. Mine was/is successful small scale which is all I wanted in retirement. It had very little overhead. But, almost any business one starts requires risk and upfront costs. So, relative to each I suppose. For those I've suppled material for a microgreens business, they usually have a starting budget over $1000 and that's a very small amount and little risk. I know you didn't ask for some of the info I supplied, but it seemed implied. Regardless, best to you G.

[@donnamarie4443]

That leftover root stuff would make really good compost. Just an idea.

[@C3Voyage]

Yes, it sure would. In my books and I've used them as worm compost. You're watching some of my first grows.

[@baris222]

Hi Brent Can you please let me know where you got that screen from? I couldn't find anything similar. I have seen the stainless steel one and the one you use in the oven. I am going to try them. Thanks

[@C3Voyage]

I bought it originally from Lowes probably better than a few years ago. I used much of it on the greenhouse giveaway build and didn't have much left so I ordered some more. This time, I went with Amazon: www.amazon.com/gp/product/B00KQ0RB42/ref=oh_aui_search_detailpage?ie=UTF8&psc=1 This is exactly what I purchased. It'll make about 100 pieces and way more than I'll need of course. But, I'll use it for other stuff too. So you know, Home Depot and Lowes carry this type of screen in smaller/cheaper quantity. In Lowes, it's near the paint/hardware area for us, not the windows area.

[@baris222]

Hydroponic Gardening & More with Brent Thanks Brent. I wonder if it is safe to use them? I don't see why not but just asking to make sure. I will also try the stainless steel mesh and compare them.

[@C3Voyage]

Sounds good to me. When I consider safety of products, I look first at how much a plant will take up or filter such things. They do a pretty good job of blocking such things in my research. Then I look at how prevalent the product is in the market and number of years used. Then I look at if it's been taken off the market for any reason. After all that, I weigh the info and make my decision. In this case my trays are food-grade so that's not an issue. Next, I weighed the materials of the screening. The screening I just bought is fiberglass and is rated for low emissions. The one in the video is vinyl coated fiberglass. I say all just to let you and others know I consider it, but I'm not over the top on it either. However, I respect every person's right to evaluate and make their own decisions. And, you should. All the best Baris. Please come back and share!

[@LivingWellLifeHacks]

Cool, looks like a no-waste method -- just rinse the roots and they can go in a smoothie or salad too. I was looking at other methods and this looks like the least waste AND the least work, so I'm going to try it. Thanks!

Sounds like a plan. Come back and let me know how it works for you. :O)

[@C3Voyage]

[@2quick4u84]

hi have you measured the yield of you MGs per flat with and without soil to see if there's difference? thanks

[@C3Voyage]

No. Complicated answer. I sorta tried soil first, but I didn't do it right. Then I went with paper towel and didn't like that. After those, I decided I didn't want to spend money on soil or the extra effort to keep the MGs clean. Soil doesn't let you rinse top down through the roots and out and it can be a haven for bacteria. The short amount of growth for the plants doesn't warrant a strong soil web like compost, good bacteria, fertilizers, etc like a grown plant uses. In fact, many suggest they can grow to harvest without anything extra. I agree to a certain extent. That means that the only purpose for media is to provide support/structure. I accomplish that through the mesh/screen and roots intertwining. So, then I never looked back. It would be going backwards in my mind (soil). Long story again, but basically I've gotten great harvest weights and adding the expense and trouble of soil doesn't warrant (for me as a home gardener) the potential of a tad bit more gain from soil. I want you to know I'm not being mean, but just giving my thoughts on what I've done. Each to their own. People can get up in arms over methodology and perceived ownership of processes. I don't. I just share 'cause I love the back and forth.

HI Brent for this grow did you do the daily rinse and the application of the AF spray that you used for your sunflower micro-green grow?

[@C3Voyage]

I really wish I could remember for you. If it's not in the video, I'm not sure exactly what I specifically did then. I'm working on fine-tuning grows now and documenting details specific to each type of grow. It's taking me some time. I've not rinsed my current grow at all. It's a mustard grow. I used AF only till the roots went into the tray below. All seems well for now, but I'm watching for fungus. The AF and daily rinsing shouldn't hurt if you want to give it a go every day or as needed. Just watch the pressure on the rinsing to prevent knock-down.

Screen, great idea as mats/soil isn't necessary as the seed has all it needs to get started. Paper towel has processing chemicals init it. Screen may contain lead, but could be pre-soaked in dilute nitric acid to ensure it was clean. Economical as screen could be reused, unlike coconut coir and other mats/grow media. Can you give details of hydroponic solution you used? Thanks!

[@C3Voyage]

Screen is vinyl. I use Masterblend 4-18-38 tomato formula and Calcinit (calcium nitrate) from Morgan County Seeds and Epsom salt from Walmart. I mix it according to Masterblend directions. Best to you and whatever you end up doing!

[@jandunn1597]

What is the "mild hydroponic solution" that you referred to that you used in the bottom of the growing tray?

Roughly half strength of my normal hydroponic solution. Masterblend 4-18-38 mixed with Calcinit and Epsom.

[@jandunn1597]

Can you share the "'recipe" for this hydroponic solution or do you have a video for making it?

[@C3Voyage]

This video shows you exactly how I mix the nutrient that I use in the heated greenhouse for 50 gallons. This is also where I grow microgreens so I use the exact same nutrient. At times, I mix the nutrient with regular water to reduce the potency for new microgreens. It's easy to divide the grams of each nutrient to reach the gallons you want. For example, 120 grams of Masterblend is needed for 50 gallons while 12 grams is needed for 5 gallons. kzbin.info/www/bejne/hoDXc3-cbcSro8k

[@jandunn1597]

Thanks for the info about the hydroponic solution you use.

So far I love the tray, but your tray looks bigger than the one I have. Can you give me any information about your tray and where you got it? I can't wait to get started!

They are standard 1020 (10" x 20") trays from Bootstrap Farmer. Google them. They have a website and also sell on Amazon which is where I bought mine. Easy to find. :O)

[@laurellee5903]

Very informative! Thank you. One thought: is vinyl screen food safe? We know the seedlings will absorb any chemical it contacts... so, obviously, that's a concern. Thanks again!

[@C3Voyage]

Source a good screen product that suits your needs for sure Laurel. For example, I use Greenguard certified standard, Florida Gold-seal approved, PVC-coated polyester screen and food-grade dehydrator screens now. But, you're right, I have read studies where plants will take up minuscule traces of some substances such as chemicals used to control insects and disease especially non-fruiting veggies like lettuce. With concern to any plastics, you'll need to do your due diligence and read up on the leeching capabilities of those plastics with particular interests in the manufacturing processes as a suggestion. There's lots of studies on it all. If it sounds daunting, it's because it is. Folks questions have led me to do more and more research and what I honestly can say is that almost everything is toxic--plastics, metals, foams, chemicals, plants, and the complex interactions of all of them. I'm not being snarky. It's true. Think of something, anything. Google that something with "Negative side to [something]." or "Is [something] toxic?" So, now I simply try to say, do your due diligence and go with what you're comfortable with. For me, I'm ok with PVC and foams. It's almost impossible to get around. FYI, the Dr. who invented the Kratky method, Dr. Kratky, just put up a video using the same screen we're talking about. He calls it fiberglass, but it's vinyl coated fiberglass. I really wish I could be more definitive, but it's all toxic to some degree. I address that in my upcoming book. GREAT question!

@@C3Voyage Thank you, Brent! I definitely will reach out with questions! I'm starting in a very small space, with 3 or 4 trays, and will build from there. I subscribed to your channel, btw.

[@angieluo6008]

@@C3Voyage Have you try stainless steel screen? Stainless steel is food safe right?

[@jimbattaglia8317]

I want to try that. What kind of screen did you use again and can you get it at any box store?

[@C3Voyage]

I'm quite certain you can get it at the box stores. It's vinyl. Feels like a plastic.

[@moyyaglover9247]

With the screen, would it be possible to harvest microgreens and leave roots in tray and solution to regrow more microgreens?

[@C3Voyage]

That is sort of a complicated question to answer. You asked it in a broccoli/kale video so I'll answer this way. If you cut below the first leaves (cotyledon), it will kill the plant. It is somewhat common to cut peas, and possibly corn, to do that with. Most others, it's not really doable because they're babies. I tried this with peas and the upcoming shoots weren't robust--much less than before. I recommend complete harvesting and starting a new grow mostly to prevent disease. The longer a grow continues, especially in a dense environment, the more chances of disease. If you want to harvest and re-harvest, I'd suggest growing aerated water culture past baby leaf stage and take the out leaves of things like lettuce, kale, chard, most herbs, arugula, dandelion, spinach, and so many more. You could create a window-sill of your favorites to pick for salads regularly.

What was your hydroponic solution that you used?

[@C3Voyage]

Masterblend 4-18-18 from Morgan County Seeds with Calcinit and Epsom mixed according to Masterblend directions.

[@heyphilphil]

The beginning of the evolution of the system. :)

[@C3Voyage]

Yes it was.

[@gegenton3953]

Should have seen this earlier, before starting my first tries with aluminum screens... thanks for sharing!

[@C3Voyage]

I know. I cut myself on them. They were my first screens. Now I use PVC coated polyester and food-grade plastic screens.

[@markbrinn3024]

Hey Brent, great videos! I've been watching through all the microgreens videos trying to find your hydroponic recipe but I'm not finding it. I've been trying your soilless method but I'm using plain water and I'm not getting the yields you show here. I'm thinking the nutrients are the difference. Would you be willing to share your recipe?

[@markbrinn3024]

OK never mind LOL. I kept watching and found you'd answered it on a question in one of your pea videos. "Masterblend 4-18-38 with Calcium Nitrate, and Epsom mixed according to Masterblend water-soluble fertilizer. I get it from Morgan County Seeds" for anyone else looking for it. I ordered mine (from amazon for fast shipping but the price is MUCH better from Morgan County Seeds). I'll give it a go when it arrives. Thanks!!

[@C3Voyage]

Sure, not a problem. These amounts are for 5 gallons: 1. 12 grams Masterblend 4-18-38 from Morgan County Seeds 2. 6 grams Epsom Salt from Walmart 3. 12 grams Calcinit (Calcium Nitrate) from Morgan County Seeds Mix 1 thoughly in water, then mix 2 to 1 thoroughly, and finally mix 3 to 1 and 2 thoroughly. I spray plants with antifungal for first few days till roots reach below into tray then add nutrient for roots only. Regular water might work instead of antifungal. I don't take the chance. Don't cover seeds in water or they'll die. Let me know how it works for you ok.

[@markbrinn3024]

Thank you! Supplies are on the way, I'll update you in a few weeks with my progress. Cheers!

In the description of my video, there's a link to True Leaf. They're who I use.

[@larva5606]

Any health concerns with it being metal instead of coco? I know the greens get the nutrients from the seeds they pop out of but any risk of them pulling up anything from the screens they’re grown in? Thanks for the video.

[@C3Voyage]

Ah, the screens. I was wondering what metal you're referring to! That particular screen was vinyl. I have since switched to Greenguard standard pvc-coated mesh screening and hpde dehydrator screen. Trying to get as safe as possible in this plastic world. :O)

[@larva5606]

Hydroponic Gardening & More with Brent thank you so much for the fast reply. Any tips on cost and where I can purchase?

[@C3Voyage]

What are you growing? I use 3 different screen sizes depending on seed size. The dehydrator mesh is in my store under microgreens. Link in description. If you want to buy there, I'd appreciate it, and it doesn't cost anything extra. Other than there, you can copy the title and do a search online from it to buy from other outlets. The dehydrator mesh I use for large radish size seed and up. The other two screens come from a company in Florida. They sell it by the foot. If you want that screen email me and I'll get you to them. My email is in the description.

[@larva5606]

Hydroponic Gardening & More with Brent will do. I’m planning on getting started soon. Going to do leeks,radish,and kale

[@thefaeryman]

I have a bunch of seed that I got from one particular because it was recommended and I have never had really good results as a micro. at some point I will order some Johnny's when the funds are there for it and try again.

[@C3Voyage]

Sure sounds logical to me John! :O)

[@tangobayus]

I get mine from Trueleaf.com

[@thefaeryman]

trueleaf/handypantry/mvseeds and what other companies they have bought out is one of my vendors. I have heard that about them on youtube but, their website claims to be employee owned and they support local farming markets. Also their seed quality far exceeds trueleaf in my opinion just is more cost. I can order standard shipping and get my orders in two days perhaps because they are one state away. trueleaf may take two weeks with standard shipping. trying out their sunflower seed compared to trueleaf to see what I like. thanks I will ask them next time about monsanto

[@nathanrogers8713]

I use Trueleaf Market for my seed. I buy some stuff through Johnnys but most of my seed comes from Trueleaf now. A lot cheaper and still very good quality.

[@thefaeryman]

I compare prices all the time lately Trueleaf has been catching up to johnny's but it's all about personal preference

[@zenlyf4487]

can u do wheatgrass and barlygrass in this manner

Yes. If the seed is big enough, you won't need the screen.

I'm enjoying your "no medium" videos. I will definitely be trying some of your methods. Just an observation on cleaning the roots off the screen; I think I would use a Walmart gift card or old credit card as a scraper. Again, great videos and cool growing methods.

[@NatureloverCa]

Is that screen food grade?

[@C3Voyage]

Not then, was pvc-coated polyester, but now I use FDA approved for food and beverage use. :O) Lots of hydro folks using foams and plastics in everything from buckets, to floating rafts, to water-culture liners. It's very hard to be 100% FDA approved food-grade in any instance. It's a good thing that plants can filter such things in the research I've encountered. For me and those marketing in the Group, it goes a long way to say, "I'm 100% food-grade." For sure, it sets people at ease.

[@NatureloverCa]

@@C3Voyage that's fantastic. I was just curious because I'm just thinking about growing microgreens this winter for the first time. Was interest in your no medium method.

[@nancypahl7755]

I like this screen method. But for harvesting, I switched from scissors to a very sharp knife. It's easier on the old hands, plus you can get a more even cut (haircut), closer to the mat, or medium, saving valuable product.

[@C3Voyage]

Sounds perfect, but watch those knuckles! :O) I see Curtis doing this as well. It's great for the masters.

[@nancypahl7755]

Thanks for the warning, but I actually have mad knife and cutting skills. I'm a gardener, cook, artist, sewer, and crocheter. I just wish I could show you a picture of the gorgeous sunflower microgreens I grow in my west facing window. They look as good as the pros.

When you harvest, why cant you eat the entire plant including roots?

[@C3Voyage]

You can! Give it a try. Some of the roots aren't as flavorful, but when you grow hydroponically, the roots are really clean. Well, for me most of the time. I also have worms I can feed them too. Each grow is so much food, most of my roots go to the worms.

Could somebody tell me how to sell microgreens. I just started to grow microgreens ( i'm from germany), but I am not sure how to approach the selling.
