Excellent Tool! Review by Bullree

Easy to install (after analyzing the instructions carefully), functions smoothly and efficiently. Has already proven to be invaluable in growing early season plants. (Posted on 4/24/13)

Ingenious Review by Desertographer

Bought one of these 8 years ago and it's still growing strong. Absolutely essential cold frame accessory for high altitude gardens where sun is intense but nights are cold. (Posted on 11/3/12)

'Love em! Review by Karl

I've had two of these on a cold frame and it's the difference between success & failure. Prior to installing them, we'd either forget to open the cold frame, and our things would cook. Or we'd likewise forget to close the cold frame, and things would freeze. This little gem of automation picks up where we leave off.
