Had a couple of ideas

I have had a couple of small greenhouses. The one we have now is in its fourth year as I recall. I had to order it from Home Depot, the stores don't carry them. It is a snap together setup of hard coated plastic, not plastic like we had before. They snap into aluminum guilds.

Took me and a friend about four hours to put it together. Last year we didn't do much with it. This year we have better plans. I will start seeds in the house about the end of February, then take them to the green house as they get hardy enough. We don't normally heat ours, but I have used a small space heater out there on occasion when winter lingered on a bit.

The first green house we had I got all excited and started the first week of Feb. I had my first ripe tomato by the first week of June! But it was way to early to start plants in our area. Had to use a lot of heat and the plants where ready to set in the garden, long before the garden was warm enough. I do try and get a couple of cherry tomato's started early as we give them to our Mother's for Mother's Day. They both set them on their porches in large pots and eat ripe tomatoes till frost.

I placed ours so that our garage blocks most of the westerly wind, our trees help as well. We still get a far bit of southern sun exposure, plus my green house has yet to blow away. I lost one of the first two the same way Derick, did.
