Mars Hydro 4x4 Grow Tent 1680D – Light-Proof Indoor Grow Tent 48"x48"x80" with Reflective Mylar

A 4x4 tent that can't hold its shape or seal out light will ruin a full cycle of work — the Mars Hydro 4x4 is built to handle the weight and keep your environment locked in.

Constructed with 1680D Oxford canvas and a heavy-duty powder-coated steel frame, this 4x4 ft tent blocks light completely with double-stitched seams and a dual-zipper door. The 98% reflective Mylar interior maximizes every photon from your light, and the multiple ventilation ports give you full control over airflow and humidity. Sets up in minutes with no tools and ships fast from U.S. warehouses.

The most popular tent size for a reason — the 4x4 gives you enough canopy for a serious yield without taking over the room. Pairs perfectly with the Mars Hydro FC-3000 or TSW2000 for a complete 4x4 setup.
