The Goliath Grow Tent, 10 x 20 ft | 1680D, Height 83 to 95 in

Sizing a Room Around the Goliath Grow Tent

Ten by twenty feet gives two hundred square feet of floor inside the frame. Standing height is 6 feet 11 inches, and the included 12 inch extension kit takes it to 7 feet 11. That works out at roughly 1,380 cubic feet standard, or 1,580 with the extension fitted. Volume is the number that sets your fan, rather than floor area. One full air change a minute needs a fan moving about 1,400 to 1,600 CFM. Derate that by a third once a carbon filter and ducting are in line. The tent gives you the ports to do it, with ten 13 in sockets and six 11 in sockets. Ten 3 in cable sockets handle the wiring separately from the air. Four square air inlets sit at the bottom, which is where passive intake belongs. Doors run front and back in an H configuration, with a rear access door as well. Four side windows and four observation windows let you look without opening anything. A heavy-duty spill tray is included, which at this footprint is not a small item.

Working Out Air Changes Per Minute at This Scale

Air changes per minute is the figure that decides whether a tent this size behaves. A small tent forgives a weak fan, because the volume is small and the walls are close. Two hundred square feet forgives nothing. Heat and humidity stratify in a space this tall, and stratification is what ruins a canopy. So plan for circulation inside as well as extraction out of it. Oscillating fans along the long wall do more here than a bigger exhaust does. The frame is the other thing to think about before assembly. Poles are 22 mm across with a 0.7 mm wall, in steel with interlocking pins. The frame is two to five times stronger than competing tents. Hang weight from the poles with a load figure in mind rather than by eye. The tent also uses 1680D fabric and a diamond reflective liner. Reflective walls redistribute light rather than creating it.
