I think the heat is going to be a drawback to growing these veggies in a GH in your zone. Why not grow them outside?

I do have an outdoor garden as well but I was hoping to grow something in the greenhouse that would make it more useful than just sprouting seeds in. I am not a flower person so that isnt an option as far as usefulness.

The cost to cool your GH would make it impractical for summer use. Once all my veggies and flowers are out of my 2 hobby GHs in late April, we cover them and they remain empty utill early October. We cover them to help prevent heat/sun damage to the poly and the painted wood structures inside. After all the plants are outside, I clean the poly and remove all the dropped leaves. I just do a good cleaning and leave it until fall.

I say go for it, why not see how they do and how much trouble it will be to cool it. One thing that i like about the greenhouse is it is pretty much a controlled enviroment.

My lettuce is'nt all gritty and it is much easier to controll the water.

I know it is going to take some doing to keep that greenhouse at 90 degrees when the outside temp is over 100.

you will have to have some way for the plants to polinate as most of them require bees.

it is going to take a lot of soil to fill those containers also. Maybe this year try it on a small scale and see how it does.
