Hi Jake! Great bargains! I too, have a GardenMart frame. 21x30. We haven't built it yet, we only have the metal framing. So I'm reading anything and everything I can get my hands on before we put it up. Placement, plastic?, shelves? heat?, questions, questions, questions. I'm concerned that it may be too tall, but then again, never had one before and know nothing about it. Any info would be appreciated. Thx.

Hi regina,

We like ours, we placed ours east-west and have a single layer of 6 mil poly on it. I like the height, it allows for the higher side openings. Granted it makes heating a much tougher prospect. We want to try growing tomatoes, peppers, and cukes in there during summer. Our problem will be keeping it from getting too hot. We have some fans but they won't be enough, we're looking into shade cloth. We like the shelving, and it is heavy duty.

Jake

Congratulations. That's about $15,000 worth of greenhouses when purchased new!
