This video shows a good way to make an inexpensive quality hydroponics container and set up for those of you that would like to give it a try :)… We used high quality compost tea from our grow boxes for its nutrients. The experiment worked fine for the first few weeks, but the growth was far less than when done in our good aerated soil… As the nutrients started to get used up,I did not have the time to replenish them; and the plants lost their green look and I made this video. I pulled the plants out and planted them back in our grow box in the outside greenhouse and all of the plants turned deep green within a week and began to grow and produce fast. I have been eating greens from them since :). I did a first video on how I set up the hydroponics and I have taken photos and when I find the time. I will do my bast to splice them together and make this experiment more detailed and comprehensive. I was going to make this hydroponics work really well using a water drain and recovery system with adding all the additives such as fish fertilizers and ph levels and mineral levels and I simply did not find the time, with all I have going on. We love our very low maintenance grow boxes with our home made compost soil and all plants love it too … the soil is made of peat moss and composts (no dirt/clay at all) and it is so fluffy and holds moisture like a sponge and allows oxygenation of all roots and the living active soil … all plants we have ever put in it simply grow like crazy and the plants are so healthy that they […]

    it just needs chelated iron and probably magnesium. nothing too chemically.

    Can you boil the compost tea or does that take away the whole point of comost tea? If you dont boil can it bring eggs/larva into you soil?

    By making compost tea you are growing a culture of the microbes and beneficial bacteria that is in the compost. I see you have an air stone are you adding any unsulfured molasses or other type simple sugar to your tea to feed the culture? That may account for the plants starting off green then loosing color as the tea culture die off. Also it might help to add some compost ever once in awhile ( make a tea bag of fresh compost about once a week or so ) . I have use worm tea in my garden with great results. I see this is an older post I am just sharing some of my thoughts . Thanks

    what would the plants look like if you added micro mineral rocks into the compost tea? would you get the same result if you started with health plants?

    Be careful of those chemicals! I know this guy who used this chemical with his compost tea called dihydrogen monoxide and that stuff can kill!

    Have you considered a biofilter? Could be the lack of bacteriological breakdown re: nitrogen cycle. Was your reservoir aerated? Perhaps a second vessel as a biofilter to promote amine/nitrite oxidation as is common practice with aquaponics.

    I read in one of your earlier comment responses that you did not add additional tea to the tea-water hydroponic solution. I'd wager that's where the problem is occurring. You mention the kale starting off green and fading with time; I'd guess that's due to lack of nutrients that would otherwise be found in soil/compost tea. Need to buff up the nutrients!

    As is the case with all hydroponics, water must be monitored and maintained, as that is the one and only source of nutrient. pH and nitrate levels at the very least should be checked and held within tolerance. I'm planning to give this a try, with a few tweeks, of course, sometime in the next couple months. I'll sub to your channel and try to remember to give an update.

    Cheers!

    and it looks like you have root rot from a bad bacteria!!!! :(

  • John hawkins 1 year ago

    you can get organic Hydroponics Solutions or just go aquaponic besides the so called chemical way is the same thing you get from organic only you have to wait for the organic to turn into the so called chemicals ether way you get noxygen phosphate and potassium!!!!!! just one way looks more appealing to marketing people like to thank they are not eating something that is chemically induced whining they do anyway it's chemistry organic or not all life bases around it !!!!!! But thanks for the video I like to hear and learn from everyone and happy gardening!!!!

    Great video… Thanks for posting… Now I want waste my time with compost tea…Maybe you could start pissing in it to give it some nitrogen…

  • justmeinflorida 1 year ago

    Just a suggestion because it makes me shake my head every time I see people drilling holes in the lids of their containers/buckets/bins etc…you can go buy yourself a cheap $12 sheet of 3/4"x 4'x8' foam insulation sheathing, cut it to the size you need for a lid (make sure it overlaps a bit to keep out light). You can make many of these out of one piece and you're not destroying a perfectly good lid that you can't replace. Plus if you need different sized holes for net pots, ie 2", 3" 4", 5", 6" you'll have plenty of foam insulation to make different configurations. http://www.homedepot.com/p/R-Tech-3-4-in-x-4-ft-x-8-ft-R-2-89-Foam-Insulating-Sheathing-310873/202530470

    Thanks for this. This is a great video for one who wants to grow hydroponically organically, with no chemicals. I also thought of compost tea as a natural solution…I see the lack of nutrients in your plants & you said they started out green..did you cycle out the compost tea or is that the same batch which you started with. Or did you frequently cycle out with fresh compost tea. Also any new insight on this experiment?

  • rcacad 1 year ago

    At least an air stone and checking and regulating the ph would help. Great foliar Kelp/humic acid 5:2, 1/8tsp/liter + a tiny pinch of yucca. They should turn lush and grow great. Dont forget a good bright light source is essintial too. I think if your just trying to take somthing and put it in box with tea with out circulating it or oxygenating it wouldn't be the greatest. A pump and a top feed drip emitter on each basket would make an amazing and efficient organic style grow box.

  • Jade Bridgwood 1 year ago

    there is no way enough air going through that tank hence why its failed and roots have gone brown
    a rich compost tea with humus wormcastings bio char and trace sea minerals would work just fine
    just add sugars for flowering

    compost tea is more work for less results. It may be good for initial treatment with soils, but in hydro its a waste of time. I would spend my time and money on bat guano or something with a NPK amount.

  • John-Paul “Johnny” Ensign 1 year ago

    Once you get the bit into the lid, you can switch the drill direction to reverse. This will cut smoother by heating up and there is less to clean up/chance to crack the plastic. :D

  • Bukid Karagala 1 year ago

    Thanks for doing this experiment for me before I would actually spend much for this project. Started experimenting with only 5 -6 seeds to see if this was possible. I'd better stop the experiment and plant them in soil when they pop up. :)

    I suppose Nitrogen may be the limiting factor when using compost tea for hydroponics. So adding some form of nitrate or its precursor ammonia or urea will give a boost. The plant uses Nitrate by default when it needs nitrogen. Ammonia and Urea will have to be acted on by Nitrosomonas and Nitrobacter (ubiquitous in soil) respectively for conversion to Nitrate.

    I have used compost tea in my hydroponic DWC system but added a air bubbler to it. It worked well and in fact I have used it successfully to clone difficult to root cuttings. As is usual I got lazy along the way and ignored it for a while. The compost tea got diluted by rain and the plants lost vigour. Added some urine to the nutrient solution as an experiment and was surprised by the new flushes of green. I know now that it works and may not need chemical nutrients after all. Guess adding worm tea, fish emulsion and perhaps some Mg SO4 may fortify the nutrient soln. However, I remember my school bio experiment where we put a balsam plant into ink solution to show that the roots have an absorbtive function. The whole plant turns blue after a couple of hrs. Can that happen with the urine or whatever muck we put in the soln or even soil? Salad anyone?

    Thanks for sharing. I was curious if it would work too.

  • Gary West 1 year ago

    what about worm tea for the fertilizer or add worms to your grow beds to help make your compost tea have worm fertilizer in it
