Growing spinach in the greenhouse?
I plan on trying to grow some spinach in my 10x10 greenhouse. Ive never tried this and would appreciate any feedback. Its a polycarbonate greenhouse with bubble wrap as an extra layer of insulation. I have a well insulated north wall, and a sand gravel floor to insulate from the ground. I plan on taking some cedar 1x6's and making some small raised beds that sit on top of the sand. Whats a good planting mix for spinach?I have a milkhouse heater for nightime cold weather. I do have some black 55 gallon barrels that I could also place on the north wall for passive solvar heat. Is this worth trying as well or should I not try it. Lots of ?'s for me, so any answers and knowledge would be appriciated.
