Question Noob: Confused on what types of lights to use
permalink
Hey wassup guys and gals,

Damn i just came across this forum, and this forum is crazy. Damn, I like everyone's setups. I had a setup about 2 years ago, but didn't get much out of my plants though. I need help on the lighting. I'm totally confused wether Metal Halide, HPS, or CFL are better for the grow room. Currently I'm looking at a 400W MH/HPS ligt for my grow room. I will be using the MH for veg stage, and use the HPS for flowering stage. I don't know if that is necessary now that I seen people growing with CFL's and getting pretty damn good results. If these people used MH instead of CFL's, would they have yielded more buds? I don't want to really run anything more then 400W because of the energy bill in HI aint cheap. Please help I'm so confused?!?

well i dont kno anythin about MH ot HPS but i do kno CFL is good for grow boxes/cabs. if your growing a plant that dosent get that big and ur using a grow box then i'd go with the CFLs. i see that u want 400 watts. so im guessing your growing anywhere from 1-4 plants?

depends , NOW< you can use a FULL SPECTRUM MH for flwrng , use 400watts for up to 5x5 growing room, smaller room smaller the wattage, in terms of mh vs/ hps, well HPS are more efficient on you bill, but a full spectrum MH will prove higher yields in the long run... but either will do nice

I started mine under 9 x 42W cfls but at three weeks purchased a turnkey growbox that has 400W super hps for flower/200W cfl for vege. I am pleased with my results.

the hps has become highly popular and highly recommeded by many....yield and speed of growth....generally are optimized. some will argue that MH gives better "quality" to finished bud with a compromise on yeild.

I have seen it recommended and I believe I will adapt by turnkey growbox with 2 MH (100W) and 1 (250W) hps. I may also supplement with some other light sources but that is as yet undetermined.

Well, it all depends on your personal preference, the dimentions of the grow box, and how much money you want to spend. In any event, I never suggest buying mh, and hps. If anything, maybe a conversion bulb, but you could also just use a hps for veg, and flower. The reason I said about the dimentions is because if you have a fairly small room, a hid is NOT the way to go. The temps will be in the 100 range if it's under 8x8. CFL are very nice for small spaces. They (most) put out enough lumens (if you have multiple) to even flower under them. Like I said, it's about your preference.

8x8, even if there are fans for ventalation? Well I'm going to be growing them in a walk in closet with cardboardwalls. I'll be hanging the light from the hanger bar, which i about 5'8" high. I'm thinking that I'll be giving the space about 3.5x3.5. It will not be enclosed until the flowering stage so I don't think it will heat up. I'm not to sure how much heat the light gives off that' why. By the way I live in Hawaii, if that makes a difference. thanks.

Unless you're using a 150w, with a fork-load of ventilation. But if it were me, I'd go with the cfl. You might not get quite as large buds as with a hps, but it's cheap, and works very well. They practically don't give off heat. A little, but it's insignificant. Someone else on here did a stealth grow with cfl (4 warm, 3 cool, I believe) and had fantastic results. For the area you're describing though, if you really want to use hid, go with a 150w, with ventalation. Hope this helped, peace.

Also, you should have an input vent, and an output. Fans will only blow the hot air around, but with an intake right where the hps is, the temperature given off by it will be removed fairly quickly.

Here is my opinion ...
if you have the room and budget go with MH and HPS
if you have the room and half the budget go with CFLs and HPS
if you have half the room and half the budget go with CFLS

or if you feel drawn to one of them - go with that.

Ah Crap, so sorry. I only really measured the space where I'm going to be groing will be about 2.5x2.5x5.75(its way smaller then I thought).

I know this changes a lot, I gues I should be running CFL then. I really wanted to use the HID lamps.
