Extend the growing season of your favorite plants! Our portable garden cold frame measures 71 x 41 x 133 cm (L x W x H), providing plenty of space to cultivate vegetables, fruits, flowers, herbs, or seed trays, adding a touch of green to your balcony, garden, or patio. And the 3 shelves can be easily moved allowing you to place plants of different heights. More importantly, the structure of our mini greenhouse is made of solid fir wood with exquisite craftsmanship, which is sturdy and durable enough for outdoor use. And it is not easy to crack or deform. And the mini greenhouse uses transparent polycarbonate sheets to protect plants from wind and rain while letting them enjoy enough sunlight for better growth. Other than that, there exist 2 openable roofs and 2 lockable doors, which not only allow you to water and fetch plants easily, but also promote air circulation. Our mini greenhouse is a perfect helper for managing your favorite plants!
