We've heard quite afew different ways of measuring our growboxes.... so i figured i'd show the way i always measure mine,(and im pretty sure everyone else uses this way too, but every now n then someone will say somethin lie length width depth, or length height width, or length x width or somehting... and for one think its kinda confusing using so many different ways... i kinda forget what i was gonna say, but heres the pic..
yip, that's how i do mine too mate, i see a lot of posts like what you were talking about, with lots of weird dimensions.......Peace out.........Sid
