Wendy - you might want to have your lights on at night so the heat they produce will help when it's coolest.

Â I think I will experiment with 12 hours per day as most growers seem to have good luck with the lesser hours and it will help with the electrical bill. Â My set up is a 24" wide shelf ( three shelves high). Â I have the option of using one-two tube fixture centered or two-two tube fixtures. Â I have not really seen a big difference or maybe I just am not knowing what I should be seeing. Â Lots of room for experimenting here.

Â I am living in Saskatchewan Canada where we are just starting to feel the urge to get outside and enjoy our gardens. Â I grow in the basement where it can get pretty cool. Â I have purchased but not set up yet a heating blanket. Â I am going to decrease my light hours. Â I find it very interesting that you found that much difference in light usage preparing for show in indoor plants NY vs FL. Â While I haven't been as vigilant with my plants as I would like to be they do get fertilized with every feeding (approx 1/4 strength) and I do repot at least once a year. Â I'm beginning to think the warmth issue is the problem.
