Hi Natanis, I got the larger Caddy but a couple of years ago. Just used it for the first time, but not having much luck. I think I have nute burns and although I'm past wk 4, my plants are all still 3". It's been hot, so I too have opened the door about 4" and set an additional room fan up to blow additional air into the Caddy. Do you have trouble keeping your pH stabilized? I have to add 4 T white vinegar a couple of times a day to keep it from hanging in the 7+ range. I keep trying to keep it in the good 6.0 to 6.5 range, but to no avail. Can't figure out what's changing my pH so much and so often???? Beginning to wonder if this is all worth it and to top it off, I mentioned marijuana to Sunlight Sheds and now they can't even talk to me because of Fed and NY laws. Hoping someyone can help me. Thanks!!
