Bougainville Wintering

Yes. Beauty of Amazon. Free returns if it doesn't work. But can also use it for other plants if it doesn’t work with my bougainvillea. 

no one really had a lot of experience so figured I would give it a shot. 

Now you have all the equipment to test it yourself. First hand experience is always better.

I am not sure any seller on amazon will accept a return if the tree dies in spring.
 

No sorry I bought the tree this spring from a bonsai store but bought the grow tent and light from Amazon.  But yes first hand experience. Fingers crossed. 

That was a funny missunderstanding. I never thought you would have buyed that tree from amazon. LOL

Good luck with your tree and please share updates.
