Our Raised Bed Grow Kit makes simple growing even simpler. The rectangular base is made of 100% FSC sustainable wood, reinforced with aluminium for long-term durability.The greenhouse combines a polyethylene outer layer that traps heat with a micro mesh insect layer in a single cover. Each layer is zipped separately, with wide openings for easy access and maintenance of your crops.The frame is made from a durable, powder-coated steel, while the polyethylene greenhouse cover helps warm your plants in colder months, extending your growing season. Finally, the micro mesh layer within prevents insects from landing on and damaging your plants, while still letting them breathe freely.( Tall Version) Our Grow Kit comes in multiple heights, with the larger being perfect for tomatoes.
