Hello everybody! I'm back

My mounted orchids are doing fine and are constantly growing. The funny thing about cattleya violacea is that it has no resting period like other cattleyas, so it has to be watered regularly all year round. Anyway, I decided to buy a little greenhouse (dimensions are 50*50*100 - width*depth*height) that fits in my room, so my mounted orchids could have all year round high humidity (especially during the summer).
Does anybody have a greenhouse like this? I was thinking of installing a light that encourages growth and the same time warms up the greenhouse in winter. I have no experience with this.

Could somebody with more expeience please me give some advise?
Thanks
