I don't grow veggies anymore since my kids are all grown and married. I grow flowers. However, when I did grow tomatoes and peppers, I saved all my gallon milk jugs. and made mini greenhouses out of them. I cut a doorway which I aimed to the East for summer sun. The door can be cut out or left on one side which would act like a hinge. The screw top I removed. The jug was held in place with a dowel sticking up through the top and sunk into the earth. The jug too was planted 1" into the dirt.
1] Will acclimate plants since the plastic softens the sun's rays.
2] Will help keep plants warm.
3] Prevent frost kill of tender plants.
4] Will prevent damage from cutworms.
This idea I have used for flowers also. The opening can be cut smaller. The idea of it is ventilation and morning sun.
I started my tomato and pepper plants mid-March when I lived in zone 5. Keep in mind that the days to harvest is not from when you plant the seeds. It is from when the plant is actually planted in the garden.
