To What Temperature do you Heat your Greenhouse?

10 years ago

I'm looking at firing up my greenhouse again because I'm running out of room in the kitchen. Hubby tripped on a pot last night and accidentally killed the contents of it and the surrounding pots. It's time to move them out of harms way. But not from the kitchen to the "refrigerator".

My question: What is a good temperature to maintain in the greenhouse? What is the safest low point for large seedlings- plants that have several sets of leaves. These are peppers, tomatoes, various flowers.

I really need to know what I should do so would appreciate advice.

Thank you
Lori

33 degrees F. although with a wood stove there is no thermo-stat.

Turns out I have not much choice - I've got it heated to 50F because that seems to be the lowest my heater can be set without going down to pilot only which is too cold.

All of my babies were okay this morning - I guess I'd better get back to work here so I can pay the big gas bill that's coming...

many thanks
Lori

In our location, I use ours mostly to just overwinter our plants & citrus trees so I usually maintain the temp around 55 degrees.
While I don't try to grow vegetables to maturity in our green house, I do germinate all our seeds/transplants in it. During this process, I maintain 70 degrees.

Depends if you just want survival, or growth.
