Hey guys, first time grower here, ive been through the forums trying to get as much info as possible. I wanted to put what I had planned out there for you guys to comment on and let me know what could be improved on.

Ive got a 3'x3'x6' veg room, ive got a 250w mh setup from my aquarium I was going to use. I also have 5 cfl bulb fixtures with "Y" fittings so I could have up to a total of 10 CFL bulbs. The plan is to have 2 mothers and about 4 clones vegging at a time. The cfl's were going to be placed above and down between the plants. Here's a couple of diff cfl's i was looking at using.

First question is will this be enough light for veg? too much?
Second, I live in hawaii and have reg temps of 85deg during the summer. Will the heat from the MH not be worth having the light? Should I just go with an all cfl veg room?

I was going to use one intake and one exhaust fan as well as a small fan blowing in the room.

Anybody have a similar setup? Whats needed to keep your room cool with that amount of light.

Thanks

you should get a 250w hps/mh conversion, if you got good ventilation then you should be fine but i needa get my 250w hps soon bro i got similar setup using cfl's to.

ya, mh seems to work best for veg growth while the hps are good for flowering. The reason I chose to go with the smaller cfl's is because they smaller wattage ones have a higher lumen/watt ratio. I could probably use that large 250w cfl in place of the mh if the heat from the mh is too high although I think the mh will put out more lumens per watt then the cfl you linked.

If i go with 7000lumens per sqft then i would need a total of 63000 lumen for my 3'x3' grow space!?! One 250w mh puts out around 25,000 lumen and the 30w cfl's put out 2100 per bulb and if I use all 10 bulbs then im still only sitting at 46,000 lumen giving me roughly 5,100lumen per sqft. Unless i threw a 1000w mh bulb or a couple 400w im not sure how i could possibly hit that 7000-10,000 lumen per sqft with cfl's without spending a boat load of cash.

The general consensus seems to be that one 400w mh bulb is sufficient for a 3x3 grow room for veg growth. If thats the case those probably put out somewhere between 35,000-40,000 lumens. My one mh is putting out 25,000 lumens so with 15,000 lumens from the cfl's I would be replicating a single 400w mh bulb right? Or does it not work like that when mixing bulbs?

Thanks for the advice

yea bro that makes sense but the MH is way hotter then that 250w cfl i was talking to this dude at my local hydroponic store yesterday an he was telling me cuz i asked him about the mh and he said it would be much hotter and might as well go with that big cfl, or get a good ventilation system for that MH. so i just picked up a 125w
