I am looking to build a RDWC with a two 27 gallon tough tote box. I am planning on using a 600 watt system in around 3'x4.5'x7' space roughly. I am planning on also going with the technaflora BC recipe for success kit but with a few other additives at my disposal, including AN Bud candy,AN bid bud, AN overdrive, AN bud factor X, AN B-52, Botanicare Cal-mag plus, Botanicare Liquid karma, Humbolt Country's Own snow storm ultra, AN Voodoo Juice, AN bud ignitor, Orca, and AN Sensyzym. Has anyone ever used these nutes with RDWC?? I used to use GH pH UP & Down but it always spiked on me and I've spoken with others and they've had the same issue has anyone else experienced this? Any other suggestions on pH buffer? Also Ive done some reading and looks a lot of people use chlorine or DM zone to keep root zone as healthy as possible? Any advice or pointers will be greatly appreciated specially on what kind of pump Thank you !!
