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

[@maboo736]

You could start with a basic Kratky system grown in a cup. No need for expensive equipment. The principles stay the same and it’s a stepping stone.

[@TerraMagnus]

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.

[@drew-shourd]

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.

[@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.

[@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.

[@ArunRaoINDIA]

or just tape the exposed edges from inside... then add the rock wool with the seedling. seems that should work as 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.

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.

Congratulations! This is something many people wish for but simply keep dreaming.

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.

[@FallofftheMap]

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.

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.

All you need is a kiddie pool and some foam board. Cut the board to fit the surface area cut holes for the cups and install a circulation pump. way cheaper and a large amount of grow room. Can also be done with totes or any other water proof container.

[@tacomilk1213]

Good idea

[@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.

Pool noodles, my friend. Just cut them in 1 inch rounds and cut a little chunk out to put in the middle to hold the seedlings. Minimal light getting through and it's a lot cheaper. 2 noodles would probably full both of your trays

[@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.

Thanks! 8" is the spacing I use for mature lettuce.

[@wlsweat1]

This is GREAT! I bought a butter lettuce a few years back and didn't plant it in the ground but it had seeds that flew around my yard and a few years in a row especially in the winter I would pull up a bunch, and take it inside and have a salad. I don't see them this time. I'll keep looking. It's kind of weird of how it did that though.

[@bodhi_bear2878]

That's very normal! Small seeds get blown in the wind. You probably havent seen any more because you pulled them all up before they went to seed again

[@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.

[@Aviation_Professional]

I forgot to give you another idea. Have you tried to move the air vertically, instead of horizontally?

[@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.

[@MrRgates23]

Use a 2 inch strip of polyester fiber. Very inexpensive and easy to get. Roll up the seed or small plant root in the fiber like a jelly roll and put it in the 2 inch cup. Snug fit and now NO algae problem. Roots grow through the fiber and out the cup. Fiber holds enough water for germination and growing the small plant as roots develop and grow.

[@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.

Very nice system and well thought out. I have been growing Kratky Method for the past 7 years and we do get quite a harvest. Your plants look happy and healthy. Recently I made a vertical hydroponic garden. In that, I tried strawberries and it just simply wasn't worth the time. I also grew spinach in the same system and that did well until it bolted. I think letuce will grow best in the vertical system and won't clog things up because they have a small root system.
