ive used them both,i prefer the knf,simply because i grow 2 veggie gardens also,the tops of the veggie plants ,taken in the dark when all the nutes are in them.No worries there. This is just a small personal grow in a 3x3 tent in my bedroom that I live in with my cat, with 4x 10 gallon pots that will be the home for the plants. You are not totally wrong, because I intend to switch out the 10 gallons I have once this run is over and add 4x new 10 gallons of the same mix, while I take the current ones out for reamending. I may not even take the root ball out and just cut the stock, then topdress and keep them watered. However since I am not going no till quite yet, it might not entirely matter if I reamend and mix it all back up vs top dress and keep the roots in there. It will have months to be stored in the garage or where ever they end up. I just have to keep it moist and alive at that point without going anaerobic, which shouldn't be too crazy depending on how I end up going about storing them while not in use.
If I may ask, what is it about the coots mix that you feel is costly? It seemed like the most expensive thing I had to buy was the worm castings/compost for the initial build of the soil (specifically the worm castings). The amount of amendments I had to add to 40 gallons of soil felt pretty miniscule. I wasn't going for a crazy hot super soil though. Something that would let me get by with water and the occasional boost of organisms and nutrients from teas or topdressings.
Not against KNF methods (I have only looked up a bit of info on that so far though full disclosure). But being able to recycle the soil I use by simply adding a few cups of basic organic ingredients seemed infinitely cheaper than how I had seen friends and acquaintances do it in the past where they would end up tossing away everything and starting fresh every time. Even more so with my own castings and worm bin. Granted that was 15 years ago and a lot has changed since then, even if they still grew the best cannabis I have seen to this day.
I rent a room in a house with other people though, so my space and how much I can dedicate to any grow setup is on the smaller side of what would be ideal. I really do appreciate your suggestions, and will almost certainly be looking into them for the future. Not a mishap in my mind what so ever <3
once i harvest the new growth i ferment it in a 5 gal bucket,equal weight of tops and molasese is all it takes,the bucket has a sealed lid,in that lid has another lid ,you seen paint buckets im sure,in that smaller lid i have a 1/4 in hole in it with a 1/4 in plastic fish tank line,about 4 ft of it and i run it into a coke bottle with 1/4 hole ,bottle has half full of water ,leave lid cracked,the plants will begin fermentation the molasses is there food,when this happens the coke bottle will begin to have bubbles in it,that is gasing off,when the bubblkes stop ,you have fermented plant juice.
that food will last you about 1 year using it to the feed schedule,then you will also make LAB rice juice fermented in milk,any way much cheaper and plenty to use,if your not buy the ocean you can always make your sea water with sea salt.
so every thing is cheap except the OHN that takes around 6 fifths of vodka to make
