Hello I have been lurking about for quite a while and finally started growing this year, I have a very small setup in a box 500mm w 400mm l and 850mm h with a 70w hps running a cmh 2700k bulb. Recently completed a TD yeilded 31g and currently running a Autoblueberry that was outside but had no choice but to put in box due to stealth reasons and having what looks like potassium deficiacy due to ph being high but thats only my guess. Like I said I have been lurking around and would like to say thanks as would never have even started if not for these forums they have been very inspirational. Keep well people I will be sticking around if thats ok.
