Ken do you have to heat your greenhouse at night in the winter?
hey brother that's a good question, I have tried but it's way too big and not efficient.
right now the greenhouse has no walls!
I tore the plastic down during the summer
Round feb or march I will put the plastic walls back up and add supplemental lighting also, i will probably build a hoop house inside of the greenhouse again this year Lol
that way I can light dep in there.
I have these wire cables that heat the soil I tried them out last year and I think they work good.
someday I hope to have a real green house with hard walls, heating and ventilation ...not there yet though
