I have 2 1000 watt hps's tilted up slightly at eachother. In a small bedroom.
It's working great. the lights foot prints barley reach eachother in my room, but they do hit a little and it doesn't cancel anything out in my room.Are you guys talking about hps and MH canceling eachother out????
Because my 2 HPS's tilted up at eachother is working so well ,I wouldn't change my set up. It's like 2 suns.Both sides of my plants are always getting full light.And the spectrum penetrates all the way to the floor.
