Get some myco's in there bro, they will eat all that algae and other nasty shit. If you have a small bio filter in there, this will make a home for them to breed. They eat the nasty stuff and there poo, in return plant get fully absorbable, fast nutrients. Iv just ordered some AN nutes with a little 'spare income'.
All in 1L:
Piranha,Tarantula,Organic B, Bud Candy, Carboload, SensiZym, Nirvana (shit hot),Ancient Earth, Overdrive and Final Phase. All for about £230, the Piranha and Tarantula retail at nearly the same on there own.
I got them off ebay from Spain. I got an email today saying they are in the post
From what I can gather organic dwc just needs a little thinking. You have to creat a bio-logically active environment, a 'home' for your mycorrhizae and beneficial bacteria, and of course you plant. You need to look after them with food, Humic and Fulvic acids. In return they look after your plant from root rot etc. I do find Organics quite fascinating, I just feels right, you dig?
Would be good to see a Organic DWC section on here.
