For me HPS gives: - Less lights - you wont need a dozen to 1/2 dozen bulbs in your cab
- better penetration than CFLs. A 250W hps can penetrate a foot.
- More lumens per watt than CFL(which is a shitty way to measure light. Lumens are for our eyes)
- Better control over heat - cooltubes will make a cool cab.
- faster flowering time than CFLs
- yealds are larger than CFLs
Now, I do use CFLs to side light in my cab and it works great.
You might want to look at either the stanlety blower at walmart (30-40USD) or the blue blower at home depot / lowes (50-70USD) for a cheap blower that you can simply modify. I have a blue blower that has 3 speeds 100, 200, 300 CFM that I got for 70USD. I took lots of metal tape and attached it to my 6" duct to cool my lights and vent out the cab.
Good Luck!
I think 100w per square foot is what "people" have said works for CFLs |
I will go see about this blue blower you are talking about (HD is a 2min walk from my door!!) cheers!!, what area is it in ?? what is it used for ??
I hope that it is enough light?? I feel as I should be adding more??
I do have a 4"(110V) fan that will be in there too

I have to disagree. My 23W Warm White CFL bulbs put out 1600 lumens and my 70 Watt HPS security light puts out 4900 lumens.
Simple division returns 69.56 lumens per watt for the CFL and 70 lumens per watt for the HPS. I don't see the advantage of the extra expense for a HPS lamp and cool tube.

hey oldschool!! thanks for the never ending tips !! sorry about that slip up on the other lighting post !! I should learn to keep my fingers off the keyboard !! I will learn someday!! but can you give me anymore pointers for my set up ??
for this grow room I don't think its worth spending the $$ on a HPS and I know if my wife see's that kinda light pluged in she'll give me the boot anyway so just to be on the safe side I won't use a HPS....
cheers
