Thanks guys, I have decided to just let the plants be and see what happens if I have to bring them indoors I will OR I will put a regular bulb in with the grow bulbs for more heat. Right now I have 4 large shppe lights with 2 bulbs each in them. The plants are up off the concrete floors with pallettes then ply wood over that. If it is just a matter of finding a small electric heater that is what I will do probably can find one for a reasonable price at Lowes or Home Depot. Oh wait duhhhh I think I have a small electric heater in my barn. Geez I hope the plants make it okay tonight as it is 30 degrees out right now at 1:30 AM.......I don't think the roots will freeze being in my barn if they were outside with no cover then different story. I am going to set up the heater tomorrow.

another question.....is there a way to mature my plants quicker??? It looks like my 5 White Widows are going to need until the end of November to mature.

Thanks so much or your replies.
