The trees inside this GH are over 5 years old in large pots and were on their last legs. I call them my special education trees. Some are rare like my Unknown Spain trees, some were just root balls that I nursed back to a full size tree. They could go outside but it only gets a few hours of sun a day. I will rotate my late ripening figs inside in a few months.
The GH is hot inside. Once it's hot, it stays hot. I keep it cool by rolling the sides up, 2 vents in the rear, and a full size screen door in the front. I have 2 oscillating fans inside on a thermostat. When it reaches 80 degrees, the fans come on. They turn off automatically.
