Looking for ideas on how to keep the temp in my greenhouse up!
Its wood, Windows all around, dirt floor, built in vents that I can close. No electricity. Gets warm with all the sunlight in during the day, but when i check the temp. in the morning, it's about 30-40! (We're having 50-60 days and nights in the 30's right now.)
Would I be better off keeping seedlings indoors for now?
Or is there anything I can do, like cover the seedlings with more glass/plastic and blankets for the night?
Thanks for any advice!
