9’ x 9’ will work, any smaller allows for too many changes with the outside temps.
Maybe when you move to your land, he will extend it, by then you will want it extended.
LOL, start your wall of water bottles on the south or west for the most heat, south being desirable and west is the hot sun.
Don’t forget to plant the cabbage plants for the winter and a lot of the other vegs will do well over the winter and grow year round, tomatoes will grow 2 or 3 years in a greenhouse.
I prefer my greenhouse to be attached to the house, in fact it has been said that I might be happier, if I lived in the greenhouse and didn’t have to mess with a house.
It is great fun to wander into the greenhouse and check things out, when you want, with out having to reach for outdoor clothes, coats, etc.
Check out solar greenhouses for great tips on things you can do, the hippies did wonders with developing solar survival green houses. Complete with fish for food and rabbits in them.
Yep, when we move I am promised a larger more sturdy greenhouse. I have moved a reclining lawn chair into my greenhouse so I can sit and bask. I don’t have a lot of “sitting and basking” time, but I think that is rest for my soul time.
I have wondered about tomatoes in the greenhouse and am anxious to try that. I could really be ecstatic with a greenhouse to walk into from the house. I would probably be found there anytime I wasn’t in the kitchen or sleeping. And don’t think I haven’t thought of sleeping in my lawn chair in the greenhouse already!!! LOL
