[greenblaze]

ok so i framed out my grow room and have all my supplies but my fans...

iv posted on many sites and asked many ways and i still havent gotten the answer im looking for.. so can someone please help me on this so i can begin my grow

some info on my grow 2 help

-its 9ft high 10ft long and 5ft wide

-i have 2 4x5 tables in their with 9 plant in each table

-above each table is a 1000w hps light with air cooled reflectors

i have one of thoes enviormental controller that turns on and off fans 2 controll temps

all i really need 2 know is how i controll the air in the room

i want 2 have the lights cooled by a different fan then the one ventillating the room becuz i hear its alot eazier 2 keep a constant temp that way...

but other then that do i just need a

intake/outake fan? and if so what size should they both be for a 450cfm room

also i forgot.... yes i know that their is many different sites that explain my question but i cant figure it out i know my room is 450cfm but iv heard that the out take should be 4x the intake and some places iv read that the intake should be slightly lower then the outtake i just need some expert advice on this one

You'll need a fan to run constantly through your vented reflectors, obviously. A 300-400-cfm inline, or similar, would be good; both ends of vented reflector ducting should be located outside of the grow area. As far as the room temps, if your room is 450-cubic, a similar 300-400+cfm (a 450cfm fan would theoretically exhaust your room in one-minute) exhaust fan would do for two lights. Get a charcoal-filter at about the same cfm as the exhaust, place the inline exhaust-fan on the filter, drawing through the filter, attach a length of 6" flex-duct to the fan, and put the end of the duct outside your room, preferably through a proper-sized exit hole (not through an open doorway as this would defeat the purpose). If intake must be incorporated (sometimes you can just run the exhaust and there are enough cracks in the room to act as a passive intake; not the case with a closed-door room, though), use a slightly smaller fan than the exhaust; not much smaller (20%?), just enough to allow negative pressure to build. 300 in; 400 out. Too much in, you're pushing odor out through cracks before it's exhausted/charcoal-filtered. Too much out, you're sucking plastic off the walls. Slightly less in is good. Exhaust should be sucked from a higher elevation, but this doesn't really matter if you have some good air-movement in the room and your exhaust is adequate. Your temperature should be 78-82 while on.

TYVM i just orderd my fans and now i can finally get going on my room... i got 5 fem bubblegum seeds i started germing last night ganna pick the best one and make it my mother... just curious u think my goal of 3oz a plant is realistic.. i have 9 plants in a 4x5 grow box with a 1000w air cooled above each bed(2beds so 18plants)

my real goal is 3p's total so i guess 2 1/2-3oz would do

"my real goal is 3p's total"
That's pretty realistic. I could see three if you veg them up to the proper size before starting their 12-hr cycle. You should veg for about two-three weeks (2-ft), having nine plants under each 1KW lamp; they'll stretch another 6-12" in the first two weeks of flower-cycle (12-hr).

thanks its going 2 get pretty complex after awhile i have 10 strains i plan on growing and im going 2 get it so i can harvest a new strain every 3 weeks or so but yea once i get some plants 2 show ill give yall come pics

 

[TurboBob]

just take it one step at a time right now. then worry about how much each plant will be worth. shit happens

so iv come 2 being sober and i realise i dont need 18 plants and it would be much eazier 2 just split the room i have in 3.... split it in half and then split one of the halfs again so i can use have of it for flower and then 1/3 of it for veg and 1/3 for mothers/clones

also seeing as this is only my 3ed grow, 1st real serious one with a good amount money invested. i figure it will be eazier to controll 9 plants on 1 table with 1 light but my goal is still 3oz a plant
