BRIAN , I think I might fix the styrofoam peaces together with window mounting foam, the thing is very sticky and expands when applied , do you think it will work that way ?? Also our winters in the past few ears seem to be more on the warmer side, last winter the ground did not froze, we had some very cold nights ,but still only on some places in my yard like raised beds the soil froze like 5 cm deep, for a short period of time . Now I know that this does not mean it will be always like that ....
JOHNNY EAT FRUIT , for me a greenhouse is needed mosly in spring and autumn when the temps are lower. In mid summer here we are HOT , so basically its not much needed . Till now, and for sure also this winter I will have my tropicals in the house next to windows cuz there,s no way I will finish the greenhouse fast enough before the frosts. Btw ,your greenhouse rocks !! Is it with polycarbonate or with glass, thought your in zone 10b ,so may not be a good comparison as to my case .
EPICATT2, I found them on amazon, they are expensive, but I,m sure I WIll find the thing way cheaper on other sites, like u suggested . Thought I will not be needing a heater this winter ,cuz my priority is first to build the greenhouse and maybe monitor the temps the first winter to see, what is the amplitude without warming it . Just wanted to hear what u all use as to heating..
Once again thanks for the great conversation that is happening !!☺
