I seen a lot of the commercial growers are using 1000watt hps on parallel movers with the light less then 12 inches from the top of canopy. Some say there are noticeable increases have been recorded with movers then the ones who haven't used them are saying waste of time. The money for a unit at the local hydro shop is about 300 bucks. The savings on equipment plus extra penetration from the light moving and closer to the plant seems to be very attractive. Im on the fence with with it. May go one more grow with the same old then have a few tests with movers. See if i can dial it in.
