Can you use glass jars as mini greenhouses?

Is it cheaper to build or buy a greenhouse?
A lot of people will think that they can build their own greenhouse at a lower cost than buying a kit. That is not necessarily so. If you are buying a standard size kit with no modifications to it, you may be able to find this at a lower price than what it would cost you to assemble all of the materials you will need.
Do greenhouses need ventilation?
Without proper ventilation, greenhouses and their plants become prone to a myriad of problems. It also ensures that your plants get plenty of fresh air that they can use to photosynthesize. Additionally, good ventilation prevents pest infestations and will encourage important pollination within the greenhouse.
Do greenhouses need direct sunlight?
Generally, a greenhouse should get full sun, at least 6 hours per day, especially during the winter.

However, in especially sunny climates, high altitude areas, or for shade-loving plants, partial shade can be better.

Do greenhouses stay warm in winter?
