Awesome bro. I like where this is going.
AP DWC is awesome for edible greens!
For buds, i actually ran a super soil and added worms to the actual soil. After its been innoculated i put a 6" layer of sand in the bottom of my beds to filter to runoff that feeds back into my tank. I also mix a lot of perlite as im running a drip most of the plants life. Toward the end of the flower cycle you can use your tank water to fill a reservoir. Used panty hose filled with raw material, a good gpm pump, and air stones to make my flower tea. Then i unhooked my drain line and just do drain to waste the last half of flower
With the worms in the soil and doing a bit of top dressing, that inocculated soil will stay good and healthy for a long time and the results are actually quite suitable.
I used Tapia and they seem to do well.
This is really cool, nice work
thats as much of the roots as i could fit in the pic, goes about another 12" past just not as thick. some issue i think iron and something else, i think from the high ph. And Im starting to think the high ph 7.8-8 is from my source water having to much calcium carbonates, i have to adjust the ph daily to keep it under 7. So a couple things i may try: ro all the water that goes in the system, or hydrochloric acid which would eat up the carbonates and chloride. maybe both. Very good learning experiment, already designing the new system which will have a growbed with worms instead of dwc.
