Sure can. Some growers line the roof with insulated reflective foil.

Indeed, Mash, and they also use old tyres to insulate the walls..

OK I am now in over my head. TYRES ??

Don't forget nailing the curtains in the closed position, and adding a little extra something to stop the UV showing.

While looking for information on the use of lime in building construction, today I stumbled upon two sites devoted to growing that magic weed.

This thread is now so far off topic, and is moving onto areas that it shouldn't, I am going to lock it after this post.

All in the best interests of the site.
