[@sulkoma]

I've loved this vid for years & wanted to do this build the whole time but never actually have I've linked it to so many people too I just finally went to start everything today & saw your guide too, which is awesome But the item you use as the main piece, the fence sleeve thing.. gosh that is so hard to find in Australia, there isn't really much like it If you can buy those items in bulk cheap you could probably just get your own shop set up to sell everything needed in kits, tbh I probably would just do that if the price is reasonable with shipping considered Everything costs so much in Australia because of shipping but I had a good look for a few hours today to try find something similar & I can't. I will likely just buy from the US but it's something like $130 for me if I do that Are there any other good alternatives you can think of? I was hoping to stick to the 4x4x50 sizing since you have the spacing marked out in the guide for me to follow with ease

For adding nutrients, see "dosing pump". We use them a lot in aquariums to add nutrients. It should work fine in a system like this to deliver a prescribed dose of nutrient on a fixed schedule.

[@SergeantDrastic]

@Family van Rensburg power of a dosing pump doesn't really matter. It's just a rotating wheel that works a peristaltic pump to push liquid through a tube.

Actually, I have grown many plants, for decades, including cannabis in hydroponics stems, and the roots get very long, I have to cut most of the roots off to transplant them to coco-coir. I have had four-inch clones with 16-inch roots. It depends on genetics and nutrients.

You really changed alot for me and my friends, we learned alot how to make a difference with very little effort and alot of fun. Thx!

[@DavidLeach1]

Great video and nice setup! That is a respectable yield from 10sqft! I’ve setup many systems very similar to yours and have been running numerous botanical and agricultural experiments for the last few years. I chuckled at the creative use of hair curlers...that is definitely the first time I have seen that lol. For a cost effective replacement of the curlers you can use either neoprene foam or a 2mil+ thick outdoor trash bag (thin black trash bags won’t block enough light, must be thick outdoor bags) cut into little squares, one bag easily creates several dozen little squares. Another thing I learned is that some plants simply do not grow well with others (mint, pepper, strawberries). The primary reason for this is the nutrient consumption and nutrient dependencies. Different plants will swing the PH wildly during morning and night and consume different nutrients at various rates, causing an unbalance. Frequent nutrient solution changes would assist in this scenario or alternatively low nutrient dosing. If you really want to boost your growth rate and yield add some Rhizoblast (or any chlorella algae product) starting from seedling in half the recommended dose, but be warned, this will greatly increase root density as well. Can’t wait to see the future yields, subscribed!

[@kolobkolobkolobkolob]

Anyone have a parts list for this setup. I like fact that the width isn't very wide and could work in the kitchen area well.

[@ivanluis2763]

I have consulted some information with a friend of mine and we concluded that it may would be a good idea to connect those PVC tubes in parallel as well, including a valve on each one, so you could periodically close the valve and disconnect that PVC tube, if necessary.

[@j.reneewhite915]

At 2 min 30 seconds you talk about the kale spreading out too much. However if you would harvest leaves consistently there would only be 4 to 6 leaves at the top and it would be less horizontal and more vertical. Hope that helps.

This is exciting. I’m in the process of setting up an aquaponics system with about 100 sq feet of space for plants built over a koi and tilapia pond. I’m building my system in the Andes Mountains directly on the equator at 2400 meters elevation, so a perpetual springlike climate where both cool weather plants like lettuce and chard thrive, but sub-tropical plants like avocados, custard apples, and citrus also thrive. My plan is to half cover the pond with a greenhouse, growing peppers, tomatoes, eggplant, etc… inside the greenhouse and lettuce, broccoli, fava beens, etc… in the exposed area.

Awesome system. I have been successful with the Kratky system with greens. The full spectrum adjustable led lights, a basic nutrient solution, and a little basic KZbinr knowledge and everyone can do this. What is becoming very expensive to buy at the grocery store can be offset with a compact space system. Just started experimenting with peppers with an air stone and a larger nutrient container and I had a few small peppers. Your system is the next step up. Happy green plants, you definitely got things right.

Thanks. Living in ND and have considered this. I've got most of what i need to get started now.

[@themyceliumnetwork]

here is an idea that may have been posted already but I am not reading through 200 comments. to take up the space in your 2" cups cut up a heavy duty black garbage bag into 4" X 4" pieces with a hole in the centre big enough for you to squeeze the seed plugs into. (like a square donut with a round hole in the middle) this will act like un umbrella to cut off the light getting into your tubes causing algae blooms in your tubes and on your roots & also stopping extra evaporation from escaping. hope you find this useful ! these can also be used over and over again & they would be very easy to clean. hair curlers are not a food safe alternative.

[@AntonGully]

If you force some heavy duty garbage into the hole it's gonna rock. Just shake it about, non-stop. You'll thank me later.

Skip the Kratky and just go straight to DWC. Air pumps use insignificant power for significant increase in yield. Kratky has its place, off-grid or far removed from a power source.

[@AyNay246]

@@kaydog890 Kratky method has more benefits than just less power -- simplicity is more accessible to many people than DWC is.

[@hotmailcompany52]

@@AyNay246 Yep this! Kratky got me started cause all it was a tote with a hole in it with some water, Hydronics mix, some clay pebbles and a net pot. That cost me like £30 in the end and I got the best cucumbers ever! It would have cost me more to have gotten a big pot and the soil to fill it and I probably would have had a worse yield too. This year I'm gonna try the same setup but with the addition of an air pump. I'm lucky that my patio is behind my garage so I can just run an air tube out the garage to the patio super easy.

[@BradySzabo]

I have an old but simple solution for changing the water level inside of the rails, just think of putting a brick inside of a toilet tank to raise the water level. Raise the level by filling a pvc pipe with sad, capping both ends and then installing in the main 4" pipe. The amount of rise in the water should be adjustable, the longer and heavier the pipe, the more the water level is raised.

[@oldGoatMilk]

The idea sounds neat for a fill and drain set up but a single small pump in your water reservoir should be efficient enough to move the water throughout the pipes.

Just a small suggest for your video editing but at about 9:40 into your video when you start talking over yourself most video editing programs will allowed you to mute or turn down the background volume and then you can speak and add new audio overtop of it without them being at the same volume because it makes it very difficult to understand anything other than that great video and great hydroponics system thanks for sharing your work.🙂👍✌️

There's lots of different methods to give support to the system (custom built shelves, wire racks, old tables, etc) so at this point I haven't included a tutorial for this support structure.

[@Snapshot424]

I built this system exactly as directed here, right down to the seeds (cause I wanted someone else to blame if it didn't work). It works great. Haven't bought lettuce since the first head matured. Now it's time to clean the whole system, but that means I have to remove every plant in every stage of development so I can break the system down. Any tips on this? All I can think of is to build another pair of rails to "transplant" to.

[@ygreq]

Do you maybe have a video where you explain what you use to feed them? Thank you!

[@ThePinkBinks]

To be totally honest - people are seriously helpful on cannabis forums. I can't grow that here but it's a crash course in hydro and what to do for other plants. It's full on info overload though!

[@MackenzieForge]

That's a really cool system. Very inspirational.

[@TourPace]

We just finished building our system based upon the specs given on the website and are very happy with the result. Question: Does anyone else's system sound like a long, continual drag on a water bong? (sorry, there is no better way to describe it.) There's no air being pumped in with the water, it's seems to be the flow between the inlet and the exchanges between each rail that is causing the sound.

[@TourPace]

Unrelated to the sound issue, the only deviation we made in the design was to use a heavy duty metal rack from Sam's Club. We chose that because it was easier than building something, and with lumber prices right now it was cost effective ($90 for a 4 foot wide, 2 foot deep, 72" tall rack), and it has wheels so easy to move around for maintenance. The metal shelves were super easy to attach the lights to as well.

[@marcusreedjuntilla7779]

How do you grow different produce in one system? Don't they have different nutrient requirements?

Yes, and you may get slightly better results for a specific plant if you had a separate system for each, but our goal is to keep it simple and we've found a lot of different plants seem to grow well with a good nutrient mixture.

[@banelenkosi9690]

Thanks for sharing. Kind of gives me a thumbs up for my ebb and flow system in the round pipe system. I guess hydroponics is up to the farmer how they want to set up.

[@jeffreydheere4737]

I've built a couple NFT rail systems that have a thin film of nutrient running down the rails. Unfortunately, a 2" netpot will not reach to the bottom of the rail and you either have to have substantial root growth already from a seedling in a netpot or put rockwool directly in to the rail to sit on the bottom in the flow. I like using netpots so that plants are easier to move from one system to another. This hydroponic rail setup, which is deep-water culture and not NFT but in the same form factor looks like it would be the perfect system to get seedlings started and get going for those first couple of weeks. Like you explain at the 12:00 mark, the reason would be that you can drill the drain bulkheads at any level on the side of the fence rail that you want the water level in the rail to stay at. I don't think you could have the water level in one rail higher or lower than the other, that'll take some thought.

[@omdraws7325]

Thanks. So you change the water weekly , adding new nutrients by powder or liquid into the water? Which pump do you use and where is the pump situated, and is it on a timing mechanism? Do you have blueprint plans for your setup? I’m new to this but keen to emulate your setup, many thanks !

[@ThisTall]

Great setup! As a total non grower, I wonder if anyone has calculated the potential of these systems in terms of calories produced? 10 heads per week is impressive! But I’m curious what portion of a persons diet they might be able to expect out of these small indoor systems?

[@oregonNYC]

It it’s lettuce and spinach, it’s essentially valueless from a caloric perspective. Lettuce has 5-8 calories per cup of shredded leaves. Even a huge salad would have 20-30 calories from the lettuce. This sort of set up is for tasty fresh veggies, not calories.

[@ThisTall]

@@oregonNYC Shame all this effort 1000s of people have made building these systems with little to no subsistence value. They seem to have better subsistence value growing/selling micro greens with them and buying food with that.

[@oregonNYC]

@@ThisTall calories are cheap, lettuce is expensive. Many quality veggies are more expensive than some meats. This type of system isn’t for subsistence, it’s to supplement other calorie sources with a fun and tasty hobby. As far as selling the micro greens, the main cash crop from indoor grow lights is pot. Other herbs and greens could probably be sold too if that was desirable.

[@400tenchu]

@@oldGoatMilk Your math is a bit off unless you have extremely high electric costs. Mine is $0.10 per kWh in US. I'm running a 8 rail system currently with about 70 plant sites. Two pumps. Each using 25W. Four LED lights using 19W each. The air pump using 6W. The lights run 12 hours per day. The air pump and water pumps run 24 hours. Now the math: Air pump: 6W * 24(hours) = 144/1000 = 0.144 kWh * $0.10 = $0.0144 * 30 (days) = $0.432 Lights: 19W *4 = 76W * 12 (hours) = 912/1000 = 0.912kWh * $0.10 = $0.0912 * 30 (days) = $2.736 Water pumps: 25W * 2 = 50W * 24 (hours) = 1,200/1000 = 1.2kWh * $0.10 = $0.12 * 30 (days)= $3.6 $0.432 + $2.736 + $3.6 = $6.768 USD a month. Or roughly $81.21 USD per year. I struggle to see how you arrived at $60.00 a month. Of course I'm using highly efficient LED lights with targeted light output. But even then, the lights would be about double with fluorescents. The clip on fans being a negligible add on at around 14W. There is entire farms who use this method in green houses with lights and they obviously profit. If it wasn't viable they wouldn't be doing it year after year. There's pros and cons to everything. The con being it's expensive to start up. But there's lots of benefits, such as little to no crop losses, little to no pests, ect.

I noticed the raspberry pi when you were talking about your reservoir @14:18 I would love to see a whole video on just that!

[@SimpleGreensHydroponics]

Wow very observant! Yeah I set that up a few years ago to monitor water temp and nutrients, though definitely not necessary. It took quite a bit of tinkering :)

Fill the netting pot gaps with coconut shell crumbles.

Consider the health benefits from eating more greens as well as the savings in health care costs, trips to the doctor, cost of medications, etc.

[@janelord3483]

Can you give me some advise please. I'm growing greens well but I just can't seem to grow them big enough. Should they have more light or more nutrients or what ,any help would be appreciated

[@ruthtran9494]

Thanks so much for sharing. I wonder about ventilation. Did you have to do anything about that? And if the veggies are indoors do they afftect the oxygen for our breathing?

Hi Great video I keep watching it over and over! Just wondering does the PVC tubing have to be food grade or can you just buy the PVC tubing from any depot store?

[@mikeclarke952]

You can buy them from any hardware store. I'm a very hardcore DIY'r (decks, rooms, plumbing, electrical, etc.) and when I put together my BOM and considered my time and all the perfect holes I needed to cut (with a hole saw of course) I decided to buy a simple system from Amazon for $120 Cnd.(90 US). Good luck with your build.

@@mikeclarke952 can you provide a link to the amazon one? I'm also in Canada...
