Little greenhouses have trouble with big temperature fluctuations. They
get very cold on a chilly night and get hot real fast on a sunny day. I
suppose the white (rather than clear) covering would help a little.
I would think you would have to add a lot of heat to keep it above
freezing in February.

I think was called the hobby gardener. They wanted 425 bucks plus s&h. It
was portable with white plastic covering and was 5X6. The price seems kind
of steep. I live in central Illinois and wonder if one would be advisable in
this area. I wonder if plants would freeze if I started seeds in early
February. Thanks for your opinions.
