Greenhouse
The plastic cover protects against the cold and against light night frost, and the tent will act as a greenhouse.
This extends the season considerably. Already at the end of April or beginning of May, you will be able to harvest potatoes and prepare the first bowl of home-grown salad.
When the first batch of potatoes, radishes and lettuce has been harvested, chili, tomatoes and cucumber can be bedded out.
Greenhouse plants will thrive in the bed. An important reason is that aeration can be much more effective than in a greenhouse. Due to the flexibility of the plastic sides, they can be rolled up entirely to let the cooling wind flow in when the weather is hot.
Many crops may overwinter and continue their growth in the early spring. You will be able to harvest fresh crisp root vegetables throughout the entire winter. Celery, chives, spinach and parsley will do fine despite light frost outside. In this way you will be self-sufficient most of the year.
