Hi,
not writting much on here, but I guess I can help you here. I've been using Sannies Buffertabs System since about 3 years now. Did most of the different hydroponics (DWC, Drop, Coco dtw, NFT, Waterfarm) before, but since I've changed I'm really happy. Not that I've had no success in the couple years before, but I like the way this system works. No pH, no EC, just add water and the BAC. No premixing soils with stuff I couldn't get where I live.
I do the regular System like Sannie recommends, I just add the BAC P-Booster and some Guano tea (Somas recipe). I do use a mix of coco/light mix/perlite/cogr with ratios 4/4/1/1 volume, because I can get this here locally. Growth rate is much better then I had in plain soil with Canna Soil, almost equal to coco/perlite. Taste is awesome, smell is very good, yield is good. If you have further question just ask.
Cheers
