Grow Room in progress

I have had a lot of luck with these, and they are very inexpensive...

fresh2 compact fluorescent light bulbs remove odor while emitting energy efficient light

just dont use them during flowering.
600 watt light is most efficient watts to lumens

Only thing that really has my mind working overtime is cooling on the lights. I know we already bounced this around but came up with a thought or 2. Question is 1 big mofo fan to cool all lights? Keep in mind that this will finally be running a total of 4 lights when complete.
or 1 fan at each light but on lights using same duct work? would also like input on cfm size for whichever route being suggeted. Thank you in advance for your input :jointsmile:

I run 4 600w lights on one fan, however the venting is 8", fan runs at 700cfm, no problems at all.

I guess my main worry was if running 1 fan to cool all lights and that fan craps out on me then I am baking whatever is under the lights!!

SN you say 700cfm on an 8" duct, are you running a vortex type fan or?? also I found a cfm calculator on 1 of the hydro sites and says for my size room I need to have aprox 380 cfm for an exhaust fan (which will be sep from the light fan) this sound about right?? Sorry if some of these questions are redundant I just dont want to buy things more than once hehe :thumbsup:

taxes are back and first purchase has been made. 2 Nextgen 600w ballasts and 2 Yieldmaster II reflectors are otw!! :thumbsup:

went and got the 3/4" plywood for floor taoday and got that put down. now to start on the walls

ordered the fans today, 2 6" vortex type, but held off on filters as I am a lil confused atm. Wtf is the difference between a carbon filter and a carbon scrubber?? 1 fan will be mounted outside of room and blowing into the light ductwork and other fan will be inside room exhausting air out of room.

;)hi tinytoon,i'm not 100%,but i think its just the spelling,if i'm wrong,i'm sure this will prompt someone to correct me,then we'll both know!:thumbsup::jointsmile:

A carbon filter goes on the outside vent to stop the smell venting outside.

A carbon scrubber stays inside and just keeps recirculating the air inside the room to reduce odor.

ok it's built and getting ready to place pots for the ebb and gro system, what is the average amount of space a plant should have?? I thought I read somewhere 1.5 sq ft but cant remember :wtf:
