Unique composite framing is designed to give you years of service with absolutely no maintenance required — just put the greenhouse up and use it. And every one of their greenhouses feature amazing Solexx Greenhouse panels, so you know your plants are getting the optimal diffused light needed to accelerate plant growth. Solexx Greenhouse Covering is strong and shatter proof to protect against wind and snow. Solexx is white for a reason — it produces an even diffused light proven to accelerate plant growth by 30%. Cutting-edge framing a combination of composite tubing (the same material used to make bridges), steel fittings, and PVC provides superior strength and stability against wind and snow. The white Solexx Greenhouse framing reflects the greenhouse light — sending more light back to your plants. Your Solexx Greenhouse will arrive with color-coded, pre-cut greenhouse frame which makes assembly easy. Also, composite material does not transfer the cold into the greenhouse (metal frames do).
