VIVOSUN S848 4x8 Grow Tent, 96" x 48" x 80" — Observation Window and Floor Tray

A 96 x 48 x 80 in tent — 32 sq ft of floor and 213 cubic feet of volume — built around a metal frame rated to carry real equipment overhead rather than just enclosing a space.

From our own use

We have used grow tents in a garage. A tent turns a corner of one into a contained grow space.

The 400 lb figure is the one that matters

Most tent comparisons stop at fabric thickness. The number that decides what you can actually run is the load rating on the top bars, because a light, a carbon filter and an inline fan all hang from them, and a filter is heavy before you add ducting. At 400 lb this carries a full lighting and filtration setup with margin, which is what separates a tent you can build a room around from one that merely holds plants.

Sizing the fan to the volume

At 213 cubic feet, the usual target of exchanging the tent's air roughly once a minute puts you around 213 CFM before losses. Add headroom for a loading carbon filter and every bend in the ducting — but remember carbon needs contact time to adsorb odour, so a fan run flat out can remove less smell than the same fan at half speed, while being far louder.

Carbon filter intervals, and what shortens them →

Hexagon-pattern Mylar versus a mirror finish

The hexagon texture scatters light rather than reflecting it as a beam. Scattered light reaches the sides and the lower canopy; a mirror finish mostly sends it straight back the way it came.

What you still need

This is a tent, not a kit — fan, filter and ducting are separate purchases. If you would rather not match those yourself, the 4x4 complete system ships specified to work together.
