What grows well in a hot greenhouse?

One great strategy is to use the greenhouse primarily for heat-tolerant crops like tomatoes, cucumbers, peppers, and basil. While shade cloth and heat-storage systems like a Ground to Air Heat Transfer (GAHT™) system can help control greenhouse temperatures, it is still a warm spot in the garden.

What can you grow year round in a greenhouse?

How do you keep plants alive in a greenhouse in the winter?

This can be as simple as the addition of one or two layers of horticultural fleece over your plants (Remember to remove coverings during the day so they do not overheat.), and place some bubble wrap around your pots to help insulate plant roots and prevent clay pots from cracking.
