CFL 6x6500k our 150watt HPS for vigiate stage ?

[ninfreak]

Would it be better to use 6x26w 6500k CFL our one 150watt HPS in a grow box of 47inch high 23inch wide and 18inch deep just asking because the HPS looks way to orange colour and the 6x26w CFL 6500K looks way whitish blue I am a newbie at this and the CFL 26watt is = to a 100watt Incandescent light bulb




thanks

Personally I like CFL's in small areas. 6500k is great for veg, and 2700k are more geared for flowering. Mixing the two spectrums is even better. If you plan on going 6 bulbs you might want to go 5 x 6500k and 1 x 2700k for veg. Then go 5 x 2700k and 1 x 6500k for flowering. That combo will give you killer buds in your small space. I'm not really sure how much heat one single 150 HPS bulb would produce, but it's probably going to be equal or maybe slightly hotter then all those cfl's together. Whatever you decide I'm sure both would work great. I'm leaning towards the CFL's since it would be more usable combined lumens.

thanks i like your idea 5x6500k 1x2700k then cfl look more natural then the HPS but i hear mix feelings towards the CFL and the HPS

Ideally for veg you don't want to use a HPS bulb. A MH conversion bulb or CMH bulb (if your 150w ballast is pulse start) would be significantly better.

Between a HPS and CFL's for veg I would choose the CFL's.

grate what about the flower stage use 6xcfl 2700k our the HPS

for flowering definately go with the hps. just make sure you have enough vertical room for it. they cannot be anywhere near the top of the plant. at least a foot away with very good ventilation. if thats not possible definately go with the 2700k cfls.

I would also use the HPS for flowering if you can deal with the heat. It's only a 150w so you should be able to keep it closer than 12" from the top of the canopy. I have a 250w closer than that. Just do the hand test - if it's too hot for the hand it's to hot for the plants.

thanks for the help my first time grow so i will use 5x6500k and 1x2700k CFL
for veg and use the HPS for flowering

That will be a good setup. Don't forget you can still add a CFL or two during flowing with the HPS bulb and get a bigger yeild. As long as you can control the heat that is.

My cab is 3x2x4 and I'm running a 250w HID hood..the only issue I have is managing temps. You've got to be pretty organized to get that done without sacrificing airflow.

If I were doing it over, I would go T5 or CFL for veg and flower just cause it's easier to manage.

CFL's do still put out heat but not nearly as much in that small of a space. You'll do well with CFL's.
