thanks for all the info about the lights. Right now my plants are 7 days old and stand at about 3 inches. Is this a good time to add the 150w hps. Can one 150w hps support 3 plants that are 2-3 feet tall? does it hurt to have two different light specturems in the room such as the cfl's and hps at the same time? everyone on this site are great people thanks for all the advice.

That's fine if what you want is to start over every time..However for a continual grow, CFL's work the best..imo..Cost of running is less with CFL..I run4.5Kcfl's and the electric is only $15 more a month, with hps, it would run me $50-$75 more a month...at least, at $350 norm,ally, that's too large a jump..Only if the ballast is one designed to fit the MH bulbs, otherwise you would need to invest the cash in a conversion bulb to fit the ballast you currently run. There's a really good article in the indoor forum that discusses light penetration, CFLs to HPS in terms of coverage and range of usable light, and although the CFLs are not nearly as efficient as HPS, lumen output / wattage speaking, the CFLs do offer great short range light; such as seedlings. Once the plant develops foliage and continues to grow vertically the light that the CFL bulbs contain is not as effective at penetrating the dense new growth. This is where the HPS has the edge as it's large light output will far outperform CFLs and will provide a much broader, denser canopy of light; more plant usable energy. If you intend on growing a whole crop with CFLs, you either need a lot of wattage or you need to redirect growth to the top with trimming to the lower third of the plant. Just my two cents, take it or leave it. Happy Growing all

I recommend that because I don't believe Weed2Die4 is running perpetually. I start over every time, I find it better to just grow smaller quantities of bigger plants. You need to put money out to get results, that's something I've come to terms with. Where I live there are 6 grows every square KM of my region so the price for electricity doesn't concern me or the authorities. I'm an efficient, environmental person as is and I only use about $62/mth for hydro now.That's fine if what you want is to start over every time..However for a continual grow, CFL's work the best..imo..Cost of running is less with CFL..I run4.5Kcfl's and the electric is only $15 more a month, with hps, it would run me $50-$75 more a month...at least, at $350 norm,ally, that's too large a jump..
will a 150 MH bulb fit in a 150 hps ballast?
