For those who have not seen my previous posts ..
I live in Toronto Canada , zone 5.
Last fall I moved an older established tree , planted it in my yard and built a structure around it. I heated it with 3 regular light bulbs hooked up to a thermostat set to 34 f .
The tree never saw freezing temperatures this winter and has absolutely no damage at all .
A couple weeks ago I took the top off the structure and bent a couple plastic pipes from one corner to the other and created a domed roof which I covered with plastic . The figloo is now a greenhouse and will give the tree a head start on the season .
With the plastic top it is still alot cheaper to heat than a regular greenhouse. with the regular top used for winter it is less than 1 tenth the cost of a regular greenhouse .
The first photo is with the hardtop. The second is the softop. The third is from the inside looking up at the roof. The last two photos are some of the figs I have in my regular greenhouse ( found used on kijiji for $400 ).
