Great growing!! I, unfortunately, have let several pass on. We had a big freeze here in Feb (down to -13) and several orchids and tropicals that were against the outside edges of the greenhouse got too cold/froze. The upside is I have some more space in there now and can move some plants to better growing locations. To solve the issue, we have added a couple of additional electric heaters for next winter - hopefully that will keep things from going below 40F.

cheers
