The Mars Hydro Grow Tents are the first LED engineered grow tent specifically for growing with Mars Hydro products. Quality comes first featuring double thick Mylar with a 99% efficient reflective surface. The tents collect and reflect any light emitted outside of the canopy footprint and delivers it directly back to the plant. These tents are designed to reflect the spectrum provided by the LED grow lights. This special surface easily outperforms any other grow tents available. These tents are quick, simple, and practical solutions to creating a controlled horticultural environment. They are easy to assemble and come with all the useful features you would expect.
