The whole time I have been here i have seen to many threads on "what light should i buy" or "will this light work". So I have some free time and I am just going to go through the basics.
Lights to use:
I'm going from the best(you can use) to the worst ( you can use )

-------------------------------------------

HPS (high pressure sodium) and MH (Metal Halide) light


-------------------------------------------

The fluorescent "tube" light.


------------------------------
The compact fluorescent light's


------------------------------

Lights not to use!:

normal light ( Incandescent )


-------------------------------------

Halogen Light Bulbs


-------------------------------------

Black light

-------------------------------------

Grow light (Incandescent )


-------------------------------------
more will be added later..( this is just a start )

wow thats alot of info cant let you do this by yourself so heres some help as you can see that Purlite stated earlier on what to look for in fourecents heres my two cents the best place to get them is here www.1000bulbs.com/category.php?category=2086 I was told by a few members here that the 85 watt would be compatible with a 150 watt reflector($6.97) from homepedopot if im wrong please correct me

Say I will be using CFLs ( Helical)...

I know for vegging I want the 6500k spectrum, and for flowering something like the 2700k, but theoretically, cant I just get 4100k and use it the whole time, or no?

[toastybiz]

No, you can't just average the conditions. You might do OK, but each phase of growth is maximized by a certain spectrum of light.

[ctcoyote16]

ok, Thanks toasty

how can i find out the light spectrum?

[mr.niceguy619]

how would my plants grow if i was in a spectrum of:55,000 lumes(sp) for veg. and a spectrum of:38,000 lumes(sp) for flowering? because i was thinking of buyin this light:http://www.htgsupply.com/productdeta...?productID=208 if anyone has any input, or can help me...please post and share your knowledge

Lumens is light output not color spectrum. You are looking at a 400w MH/HPS combo, which is a great grow light depending on how many plants.

well a 400w hps/mh......i was hoping i could grow 6-8 (do you think its only big enough for 2 plants?)

[toastybiz]

400w is fine for 6 plants. I think 8 is pushing it.

I'd like to see more stuff on Fluorex bulbs. I just bought one (being shipped now) and am going to try it in veg cycle instead of 400w HPS. I did a little research and they look like they might beat CFL on price vs. effacacy.
