Greenhouse In canada

[isdaojon]

Hello everyone,
I have been thinking very seriously of building a greenhouse to house my evergrowing orchid collection.
Space is running out in the house and conditioons aren't the best for some of them. Also I would like to start mounting some of them.


I live in Toronto , Canada and am asking for advise from people who live here in Canada or in the northern part of the U.S.

I need help with the fallowing:

1.What are some good greenhouse sellers here in Canada?

2.How can you heat the greenhouse in the depths of winter when it falls to 20-c or less?

3. What are some good designs for an orchid gh?

4.could you tell me any advice you have from experiece with greenhouses for orchids from your experience?


Thank you all so much! This will help allot!
