I want to use it to get a jump start on daylily seedlings in the spring. I'm so over starting them inside during the winter. Some veggies and a few other things would be started in it as well. No plans to heat it ....
I know that bigger is always better, my husband used that logic when building his pole barn. Funny, that he doesn't think that way when I'm contemplating a greenhouse. I liked that if I start with a 8 x 16' unit, it looks like you can add on.
