My last rig was a combination of x2 strips and cobs but it was a bit too big to be practical for working on and when in use (and i kept hitting my head on it) .My current rig is two frames of x2 strips with a driver each so i can use them independently of each other or together as one bigger unit. Also it means i can vary the height of the rigs to allow for tall and short plants in the same space. I’m loving this rig, best i have ever used and future proof
