No, I quit using that quite awhile ago Elaine when I switched to the potassium nitrate. Ok, that makes sense, I can do that. Just keep my log as I do with my feeding schedule so I don't forget. As far as how warm, well hopefully not as bad as last year when it was in the 100s. This year I have the 60% shade cloth on the greenhouse but still its already been in the upper 90s but once the trees leaf out it might be a bit better. Also I'll have my power project finished soon and will be able to run fans in there this year pulling air in through the north window so hopefully it will make somewhat of a difference. I'd rather not try to move them outside with all the squirrels, pigeons, doves, grackles out here and if I'd leave them out overnight there are always the deer doing their grocery shopping.
