What temps should I maintain as a minimum before I put my tropical plants in it?

[Guest]

We just finished building our greenhouse and now I’m wondering at..

Whatever the lowest temp is for your most vulnerable plant

It depends on the tropicals... say alocasia then 60. My personal general goal is 50. Something like a ficus or a marginata will be ok in upper 40s.

Although it is plant specific, “a greenhouse should maintain an ideal temperature of 75-80°F during the day and 60-70° F at night” but a thing lower than 50°F can start cause problems”

“Most will not survive at frost temp or below 40° F. “

Hope this helps

I grow tropicals and succulents and I shoot for no less than 50 degrees. They don’t need to be at higher temps at night.
