Please help. Summers here on the California coast are often below 50 degrees and I'm strongly considering purchasing one of the following greenhouses at Harbor Freight before I start my first limited OUTDOOR grow involving a maximum of 6 AK 48 plants...Harbor Freight Tools

A greenhouse will retain heat into the night, protect the plants from the plus 15 MPH winds we often get here every afternoon, keep them dry when it decides to rain here and there, prevent mold from developing, and finally, help confine odors during flowering and alleviate detection, I hope. Ak 48's reportedly smell a lot.

Q. My only concern against a greenhouse is this: Does the polycarbonate diffuse the direct sunlight enough to warrant not using a greenhouse throughout the summer?

I can't find any pro's or con's on this subject on the site, so I hope you'll give me some feedback, and soon. Thanks!
