Whether you are new to gardening or quite the experienced gardener, a plastic polycarbonate greenhouse is the perfect choice to helping you achieve your growing goals.

Twin wall polycarbonate is 100% UV protected, longer lasting and diffuses light better preventing it from scorching your plants.

The greenhouses double sliding doors allow easy access and the rear sliding window offers a quick way to ventilate the greenhouse on those hot summer days.

There are screw holes in the framework which allow the greenhouse to be attached and anchored to a base of your choice.

  • Brilliant Product

    Posted by Andy Carter on 22nd Feb 2015

    I ordered the Ultimate Greenhouse (1.2m) on 3/2/2015 it arrived on the 13th.I sorted all the parts out and it was erected by the 17th. The instructions were very clear and easy to follow. The end result is extremely pleasing. I built two lots of staging out of old pallets and have already filled one with seed trays. We have had some very heavy since I built it and it is completely dry inside. Your product is very good value for money and I would not hesitate to recommend one to anyone else.
