Just made a cold frame to move some tomato seedlings too, is my angle too big?
So I managed to scavenge a couple of old windows and have turned the first one into a cold frame. From my research the angle recommended was 30 degrees for the slant of the window however on all the cold frames I see online and on youtube the angle seems to be a lot lower. Have I done something wrong here? The angle is definitely 30 degrees that I have made it. The hight really works for me though as I am going to put some tomato seedlings in to start hardening off.
