Light movers are fanfukintastic if they are used in the proper way for the right reason,they will not increase your grow area the way they are advertised,this is not their strong suite,what they are great at is crerating an evenly light canopy at all times.
I use my movers 3 at a time covering the exact same floor space that the 3 lights would normally cover just hanging there,by doing that the moving lights will give the most intense portion of the light to the entire grow area & no area of the grow will ever be under light at any time,the plants on the outer edges will recieve the intense light the plants in the middle of the grow receive.
I use a single for veg but running 1 mover at a time is pretty much useless in flowering,if yo8u want rock hard dense nugs you need multiple movers witth multiple lights.
