I heated by just putting it in a semi shaded area outside with the plastic cover still on during the latter half of a few summer days. I had a thermometer constantly measure the temps and it made sure it got no higher than 95 degrees. When it got too hot in a certain area, I just moved it somewhere else (I have a large yard with lots of trees) that was appropriate so it didn't get direct sun and burn to a total crisp.
I don't know, maybe it was a VFT that got exported from someone's factory in Canada or something and it didn't take to the heat to well. [img]http://www.**********.com/iB_html/non-cgi/emoticons/biggrin.gif[/img]
Ok, at this point I have to assume that the thermometer was OUTSIDE the plastic cover, correct?
If so, it was a LOT hotter inside that plastic cover. Basically a greenhouse effect. That's most likely why the plant cooked.
What I'm talking about is an Open Air situation that is merely applying mild, controlled heat from the bottom. And these plants are already established in this environment and doing fine---I would just be adding mild heat. That's all.
