Paul, thank you for this info, though I am some what confused.
I have never heard of par. You have a great setup. You sure know what you are doing. Are you a commercial grower? What do you grow?
Ken, I understand what you are talking about. The seedlings are already growing, I just want to keep them growing during the winter. I'm not looking for blooms at this time. I'm growing Kedrostis, Ipomoea, Ibervillea, Euphoria, and a few other caudex forming plants. There are under 10 plants of most species.
As for going to specialty store, it is hard for me. I depend on my sister and dad for transportation. I don't ask to be taken to a lot places out of courteousness to them. I am grateful for where they do take me.
