After doing a few good soil grows thought it's time to try hydro! I chose drip because it's economical with water, which is necessary in my situation. 3x PPP from Nirvana, about 2 weeks old 8x 2' T5 bulbs on 18/6 off GH Flora grow @ 500ppm Feeding 3 times a day, 8am when the lights come on, 2pm and 8pm. Two questions: the PH in the system seems to rise every day. It was at 6 yesterday, now it's at 7.1... Also, should I add more drippers? Not all the hydroton seems to be getting wet. What do you guys think? Any recommendations or something I missed?
