2001 Growers Log - May
The Cramer 824 is doing very well and beginning to vine. There was some discussion earlier this week about opening devices. I've been using the one in the photo on my cold frames for several years and it works great. There is a small knob on the device (not visible in this photo) that allows you to set the temperature at which the device will lift the lid. The one I have is available from Lee Valley Tools.
