Most of the vegetables that we grow in the garden grow best at a temperature of 20-30 ° C and humidity 70-100%. In Siberia, we have such weather on the strength of 2 weeks in the summer, and even then not every year. The only way out is indoor cultivation. Greenhouses are quite expensive. In addition, they cannot withstand snow loads in winter. But the compact greenhouse, which understands for the winter, is a very good alternative, both in terms of money and ease of use.
I bought Clover 2 years ago. Now I have on the site already 2 factory lengths of 6 m and one home-made. Tomatoes, peppers, eggplant, cauliflower feel great and fully ripen. In addition, these greenhouses are good pest protection.
pros
keeps the temperature up to -2-3 ° С on the soil surface, vegetables do not freeze, cheap, easy to use
Minuses
the structure is rather weak, you have to strengthen it with homemade products - stakes, clamps, repair arcs, etc.
