I had some scrap lumber and 4 mil plastic sheeting lying around and decided to build a small green house. My craving for fresh vegetables as we settle into late winter. This is fairly experiemental and done without too much research or bothering to do all the maths. I’ve planted some beets, broccoli and argugula with the hope of harvesting in early spring. As we approach warmer days the house is portable and can be pulled off. To create some thermal mass I’ve put some gallon jugs full of water and created a black plastic 2 gallon bag suspended on the early morning side to get heat all day. I am going to get a thermometer with a high low setting using a Home Depot gift card and try to avoid overheating or freezing. My oldest daughter is very interested in the greenhouse so hopefully this will be a good project for learning together which is always best. Comments and advice welcome.
