so i flowered once using a 400mh in a horizontal reflector with 5 small plants and got 3.5oz off it. i switched to 400hps but they used the gym reflectors vertically. out of three plants the same size i got 41g. this seemed backwards to me and im just wondering if changing the hoods to horizontal would fix this. also im looking for quality low cost full reflectors if anybody has their opinion.
