Tomato greenhouse with a slanted roof. At the beginning of growth, it is important to protect the delicate young tomato plants from the weather. This XL tomato greenhouse is designed to shield against frost, wind, and UV radiation. Its slanted roof allows rainwater to easily drain away. The extra-large base area of 200 x 80 cm provides plenty of space. Melons, chilies, or eggplants can also thrive here under ideal conditions in the cold frame. By adjusting the zippers to different widths, you can influence the climate inside. Tip: Set the tomato greenhouse a few centimeters deep into the ground for added stability.
