I kinda put myself in a bind. I started germinating 3 Autoflowering Afghan Kush Ryders..one in my grow journal..I have 4 white widows that are about day 35 of vegging. About 4 days ago installed my 400w HPS light (rocks by the way) and they have starting growing like crazy. There about 8 inches now. The issue I have is I have one grow tent. Prior to the tent set up I had them in a ghetto grow box where I had a billion CFLs and a LED Panel above them. My bind is when I start flowering and should I do that now?...I wont be able to use my grow tent for the Afgan's. I would love to use my HPS light for them. Should I start flowering now? If the Widows double or more then I would be happy with 16-20 inches. Should I just wait let the Widows go at it and use my old ghetto rig for my Afghanies? I have my timer when its set for 12/12 7am to 7pm dark 7pm to 7am light. It would be a pain in the ass to put the afghans in for only 12 hours and take them out. Thanks guys!
