Since the body of your greenhouses are opaque and not clear, won’t that inhibit plant growth?

On the contrary. The opaqueness of our fiberglass greenhouses offers benefits and protections that glass panes and plastic sheet-ed greenhouses can only dream of. First, the materials in fiberglass actually enhance and brighten whatever amount of sunlight is present and evenly diffuse and distribute that light from floor to ceiling throughout the interior. Second, this opaqueness which you speak of prevents the scorching of your plants due to overexposure to direct sunlight. And that equals less busy work and less ruined plantings for you.
