Kinda jealous of your orange toy. I've been diggin a pond with a shovel. 30+ hours so far. I'm ripped now.

I found that, although it would heat up very nicely during a sunny day, the soil temperature was too low for the plants to really grow. It only held them, you might say. If it was sunny and 20 degrees (F) outside, it could still be 70 degrees (F) inside, but the cold soil was maybe 35 (F) and would rise a bit, but not enough for our lettuce, spinach, and radishes to grow. I have spent the last year building a system to add bottom heat, which I believe has got to help a lot. Welcome and good luck to you!

While I'm in total admiration of the greenhouse (which I'm sure will gain a lot of seasonal heat this summer and be more clement next winter), what I feel most is pure envy for the deep black soil in your first photo!!! Someone has been doing something very right on your land!

Pamela Smith wrote:I would build beds about 2-3 feet high. The cold tends to sink to the bottom. It will allow cold to settle to the floor leaving the bed warmer. If you put in planks in the alley way slightly above floor level it might allow the cold to settle under the planks. Making the whole greenhouse feel warmer.

I believe with the polydress and beds you can raise the temperature to an acceptable level to grow cool weather crops and maybe others as well. Start warming climate seedlings way earlier anyway.
Mike Schroer wrote:Comment on sealing the joints. I have read that the cheapest and easiest way to seal the joints is to cut another sheet of the polycarbonate material into 3 - 4" strips (7 - 10 cm) and screw that in on top of the seams. It makes a pretty tight joint and routes the water off the joint. You might see if this would work on your application.

Anyway, this was far from perfect and yours is absolutely gorgeous with the rocks, but maybe gives some ideas for future projects !

Judging from the dark rich soil under your greenhouse, the style of your outbuildings, and the cold weather, you must be in Hargita County. I'm guessing Csík ...
Question: why did you decide to build the greenhouse frame using metal? Did you consider using wood ?
