Hello all. I'm using a BCNL Producer and I'm definitely going to scrog it (grow journal link at bottom of page). I'll demonstrate what I've done. These go on the outside of my box as a back for the magnet. They are held in place solely with magnetic force. These are the magnets on the inside of the box. They seem to attach with considerable force when they connect. I've glued hooks to each of them. This is what happens when I used a net that was a little too big for my dimensions I cut out one square and this is the result. A tighter net I think I already know the answer but I want to go with a tighter net, correct? What do you think of the magnets, is this a viable plan for growing with a scrog? My trellis hole size is 4.75" by 5.5". Too big? I am new to scrog but not to growing.
