Homebox XS 

The small sized Homebox XS is perfect for limited growing areas. This compact indoor greenhouse is also lightweight, weighing only 20 pounds. 

Great for beginners, the Homebox XS is a complete grow room tent that you can assemble it in a matter of minutes following the simple illustrated instructions and well labeled parts.

The Homebox XS is made from 100% Black-Out fabric with a water-proof reflective white PE inner lining. The tough canvas outer tent even provides equipment and filter supports, plus ventilation windows.

The Homebox XS has a metal structure frame with strong nylon push-lock corners for sturdiness. Once assembled, you have a grow tent enclosure that is completely sealed and virtually light proof.

The top-to-bottom zipper, combined with the side-to-side zippers at the floor and roof, gives you easy access to the interior of your indoor greenhouse. There's even a removable floor that's water-resistant and washable.
