I am so mad right now. still have plants in my apartment going to take to the farm this weekend. All first year (5 cascade and 5 chinook) I keep them in front of a large window, and drap a sheet behind them so people can't just look into my place. didn't check them for like two days as i have been super busy. today I looked at them, and my biggest cascade (~42") grew up quick in those few days into my grow light and appears to have overheated a section about 1" below the tip and turned it brown.
Also had a chinook get caught on the draping and broke the tip off that one too.
Oh man, it must be time for a homebrew!
