SHCS for a Pre-Fab (Harbor Freight) Greenhouse?
Can I use the SHCS system for my Harbor Freight Greenhouse?
I have tried to read the articles, but it is a bit confusing for a newbie. I need SHCS for dummies. ( :
I will only be growing plants in pots, not in the soil. (Using this for starting plants and holding over sensitive ones) Greenhouse is 10x12 with peaked roof of 10 ft. and four roof vents. Air cubic Volume is only 1080 and I only need to move a small amount of air. I think I only need about I need 159.6 feet of 4" tubing. I have very heavy red clay soil.
1) Do I have to build a concrete foundation? I was just going to put the greenhouse frame on brick (over sand) and put in a brick walkway inside.
2) Can I bury my tubing in the clay or will it clog with dirt...do I need to use rock instead? And if I do that, how will it get any heat exchange with the soil? DUH.
Thank you in advance for helping me. So far I have read some of sunny john's info and will be looking into L. David Roper's site (I just read about it on this site).
