Hi all:
In Zone 7b, interested in growing citrus plants.
CURRENTLY, after my initial greenhouse plans did not work out, I set up a "greenhouse" in the garage. Keep temperature above 60 with electric heater, have multiple grow lights set up. At this point, all is well. And my backup plan is to expand to 10x12 next fall if need be.
WHAT I WOULD LIKE is to set up a 10x12 heated greenhouse in the backyard. HOWEVER, my research so far tells me that it's not realistic without significant heating costs to keep a greenhouse over 55 or 60 degrees.
What do you think? Anyone done so in a comparable grow zone? Any thoughts on a likely heating cost (10x12, zone 7b, 55 degrees)?
If the heating cost is more than $75-100 a month (natural gas or electric), I will probably just continue in the garage. I'd enjoy an outside greenhouse, but it just doesn't seem worth it for costs above that.
Thank you.
