Now I just need shade cloth, heater, fan (and electricitiy of course) and I neee benches.
But aside from all that I will soon be growing some intermediates all year round outside.
3.6m x 2.4m x 2.5m - twin wall polycarbonate which is 4mm thick on an aluminium frame. I have heard this is efficient but we'll see how it goes. Mainly Paphs and Phrags in this one......maybe one or two Bulbo's as well.
I've not fully utilised the greenhouse my hubby built me in Feb (yes it was cold work putting it up), but I've really enjoyed having a lot of my orchids out there all summer. Some of them will stay over winter and really the purpose is for my cool growing orchids.
