I have a 3x3x7 tent with a 120w qb. And Vipaspectra 600. How far should my lights be from plants? I’m having some drooping and I think my lights are to close to the big plants??
About 12-18 with the viper...kinda depends on how much area you are trying to cover...I know for fact they don't flower well much outside the dimension of the light..I think at 12" it's only has about 400 ppfd.max.i don't have the other light so I can't say..but the viper will never wilt a plant..it's a great seedlings,small veg light..
