See thats nice, got a good system going! I would be more have to deal with evaporation and making the solution to strong. I did a few runs automated with res, but found with the evaporation from the dryness it made the solution spike in strength, so I pretty much just handwater my shit. Just 3 or 4 plants so its not a biggie...until 4 weeks into flower, then I feel like im on permenent water detail.
How are the big whites handling wise? I did white widow a few runs back but they just seemed to want to runt out on me. Are these are ak47 mixed with nothern lightes?
