You bought a 4x4 tent/ light combo kit ?
what do you mean with "u postition rated but they are designed for vert" thanks for the reply
Thanks for the reply, and clarifying the vertical. Where are you growing? In a tent ? Cmh seems to be the best bet. led looks good but it is hard to find a reasonable canadian source
I'm not growing in a tent, open room.
Thank you, what is the coverage like for 1 of the sun system 315's? Do you get more coverage with a vertical bulb ?
It's solid for 3x3. Acceptable out to 3.5 for the outer branches in my opinion. My 315 actually has higher par readings @ 18" directly below the light than my double ended 630. The 630 has a little wider coverage though, solid for 4x4, acceptable for 4.5 but if you have a 5x5 tent it does well, I know of a couple people running it in a 5x5 and doing well. My area is more open so I loose a fair amount of light. I'm very happy with my 630de but put it this way, if I go buying anymore cmh's they will only be the vertical 315s. Much better efficiency of lighting per sq/ft, they cover almost as much as my 630 at half the watts.
When I was hunting, I found these white ballasts that we're a bit cheap looking, I ended up with this black Prism Lighting Science ballast. It appears to me that Prism sells their ballasts with Sun Systems hoods and Sun Systems sells their hoods with Prism Ballasts. I'm not expecting top of the line, but I'm thinking the ballast is decent enough to partner with Sun Systems.
Good point on going vertical and the light degrading, I have never really thought about that. Another question I have about running a 315w cmh, is the noise the ballasts produce, I have read that they are noisy from some people and pretty silent from others. Do you have any idea what kind of noise levels come from the ballast?
