I'm building a 12 ft x 13 ft green house onto my home. I have some wood rot and stuff to deal with so I decided to remove the two windows, replace them with a sliding glass door, and attach a greenhouse directly to my home. Should I go with concrete block footings filled with bag cement or form it up and call a cement truck to pour the footings ? I'm just doing the sides and front as the greenhouse will be a lean-to style. Wood frame and 8mm polycarbonate double wall panels. the floor of the greenhosue will be weedstop with pavers and gravel.

Just used a weed barrier for ours.
Use the footers typical for your climate.
What are your goals with it? If 4-season, it may be beneficial to trench down and insulate the perimeter and leave the earth exposed inside.
I just went down 2ft with pink board for mine. The insulation will help keep the greenhouse soil warmer overnight, and will help prevent the ground frost from sneaking in.
