Thread: Lighting

Hey guys question for any of the lighting experts on the site. I am using a 1000 watt hps to flower a 5' x 5' area. I find that the outsides are a little shaded. I am just wondering what the benefit would be to adding additional light. Usually I get 28 grams per plant, but I have limited space. So if I added another 400 watts during flowering what would be a reasonable expectation on my return?? Any help or experience anyone has would be greatly appreciated.

I use a 400W HPS and it covers 3.5FT SQ, A 1KW HPS will cover a 5x5 area well, I wouldnt add anymore lights I would change your style of grow if your unhappy with yields.. What medium r u using?

The strain is california orange and chronic. Both I thought were pretty good strains. From what I am getting you flower 1 plant under 650 watts? I am only getting 40 watts per square foot. This is why I am asking if extra light would be beneficial.

My medium is promix. I veg for roughly 14 days and flower for 60. I say a guy in the hydroponics section who flowered 8 plants under 3 1000 watt bulbs and says he got 6.75 ounces per plant. I am wondering if the extra light is worth it.

yeah maybe some extra veg time would help but they end up 4' tall as it is and there are roots coming out the bottom so I don't really know how much longer I could go?? Our pots look the same size, mine are just over 11 litre which is nearly 3 gallon. Do you use CO2, because I don't.
