Ok, thanks. This is the kind of reply I was hoping for.

Heat shouldnt be an issue. I have a tent but was thinking of using a regular bedroom for the flowering this time. Its cold outside now so if it gets a little hot I can just open a window. Will be running fans of course.

1 or 2 plants probably. I dont need much, I will use it for pain and will make a tincture of it. So I could buy a really expensive light but I feel my need dont justify it.

The younglings I was thinking of keeping in my bathroom by the sink, or possibly the tent. 

Btw, what is the lowest recommended grow temperature when flowering?
