I tried my best at hydro and possibly would have pulled off a grow if I hadn't burned my babies up by having the HID light too close and it getting 95 degrees in the grow cabinet. But the grungy fungus-filled rock wool, making sure the pH was right, adding nutes every week, checking the ec, ppm, pH, temp, adding ice packs, etc, etc. was really a PIA. NonGreenThumb has shown me the light on some of my mistakes; I now know that light + nutes = algae so I cover my rock wool. I bought some Fox Farms Happy Frog soil and I'm going to start a grow in that in the next week or so. I'm mixing that with a bag of Miracle Gro Organic Choice, some bone meal, some blood meal, some perlite, and some dolomitic lime. It's probably slower but should yield better quality bud. Next spring I will have some clones ready to go outside to bask in the great outdoors. Since I have so much invested in my hydro unit, I'll keep on plugging at it, trying to get a crop to fruition but I'm not putting all my eggs in one basket anymore; I'm doing rock wool for now, soil in a week or so, then probably firing up the hydro again.
