paulk- The whole set up cost about $600. The hoops were free as it was an abandoned greenhouse the the grower was happy to get rid of. The poly and inflation fan cost $300 and about $300 for lumber. Thats not too bad considering I'll have a cozy place to work all winter (A friend just donated a wood stove ....the boat shed is going to be more comfortable than the house this winter!)
When you start applying the epoxy barrier coat and/or using chemical strippers, you should remove the ends of your greenhouse AND wear a VOC mask. This stuff can do neurological damage, so treat it as a serious hazard.
For ventilation install an exhaust fan in one end and an inlet vent in the other end - easy to do. Depending what paint you use a positive air supply mask is a good idea too.
