Ferna

From Ferna we stock one model, the Home Grow Box, in four sizes: 60 by 60, 80 by 80, 100 by 100 and 120 by 120 cm. So there is no series to work out; you are only choosing the floor area.

Where it sits, and why the height is in the title

All four are under Grow Tents. Every title gives the height as well as the footprint, and it climbs with the size, from 160 to 200 cm. Check that height against your own space and against what you want to hang inside: a lamp, a filter and the hanging gear together eat more headroom than most people allow for.
