I currently am running a 4 plant RDWC system under 2 viparspectra xs2000 240W each in a 4×4 tent. Temp lights on 78 and off 70. Humidity when lights are on 55% off 47%. Current Res was at 625 ppm with pH 5.9-6.2 steady in week 5 of veg day 33. I have a res change today and plan to bump up to 750 with the thought of day 36 starting a 36 hr dark period and flipping to flower following.
Nutrient Using basic AN 3 part along with botanicare additives of Silica, cal-mag, karma, hydroguard. Along with several Recharge to the res but learned recently in a message with Dude that I should stop that.
