The highly functional Deluxe 4’x12’ Greenhouse is constructed with a strong aluminum frame and twin-wall, UV protected polycarbonate panels for great heat retention. The Greenhouse extension kits connect to make the 4’x16’ – all the parts you need are included. The corner stakes slot into the four corners of the top level of a 4’ wide Frame It All™ raised garden bed for great stability. Both side windows lift up for total access and have stays to hold them open at your desired height level for free air flow. Erect at the first hint of spring to seed early and provide protection from adverse weather to your young plants. The window panels can be easily slid out and stored in the hot summer months, then replaced in fall extending the season into the winter. It is as attractive as it is functional! Raised gardens are better than in-ground, for growing at home because: you control the quality of the soil and nutrients. You will also get a larger crop of easy to pick, veggies, fruit and flowers. They are easy to manage with access from all sides and because they’re above ground they drain better. No clumpy, heavy soil to turn and almost no back-breaking bending over to weed! They are quick and easy to assemble with little effort.
