1.2m Grow Tents

About

1.2m grow tents – 120 x 120cm – are the single most common tent size in UK grow rooms, and for good reason. The footprint matches what one proper fixture actually covers, it fits in a spare bedroom, and a 5in or 6in fan and filter is enough to control it. Why 120 x 120 is the default size It matches one light. A 600W HPS or a 450-660W LED covers 1.2 x 1.2m almost exactly. Nothing is wasted at the edges and nothing is left dark. It is manageable. One fan, one filter, one light, one timer. No zoning, no balancing two fixtures against each other. Everyone builds one. Bud Box , Gorilla Box , HomeBox , Green-Qube , Secret Jardin and AC Infinity all make a 1.2m, so you have genuine choice on price and build. 4 to 6 plants. Comfortable with a normal veg, more if you train them. 2.0m or 2.2m tall? Most 1.2m tents come in both. Once you subtract pot height, hanging distance and the fixture itself, a 2.0m tent leaves under a metre of usable canopy. Go 2.2m if you run HPS, use large pots, or veg for more than a few weeks – see tall grow tents .
