we do get it my friend, hps = better yield. i have done several hps grows with strains such as lr2 g13 haze bubblegum warlock and at the mo 400 hps blue cheese.. wat the issue is is heat where i grow, i have copters cruising at night and 32.c heat belting out of my shed isnt a gd thing lol. im sure most cfl grwers have just as gd a reason for there choices, i know with gd ventilation etc etc but the vents gotta go somewhere and not evry1 has somewhere to put it, also cfls do give a nice quality little plant which will q easily give the grower a healthy stash, wat i was trying to achieve wit my 1000w watt was lowr temps more stealth and still get a decent enuff yield to make it worthwhile
hps is deffo better if u can but cfls arnt to be sniffed at either

A non-air cooled 4 bulb 250w fixture is going to throw off as much as if not way more heat than a 1000w air cooled bulb. How is this less detectable? At least with the HID's you just run the vent so it looks like you keep your washer and dryer by there. The dryer vent pumps out WAY more heat than your grow room. How are choppers going to see that. They only see it when people vent 6 lights into their attic over one of their bedrooms.
And at least where I live they need a warrant before they can do any of that anyway. It's not the "helicopters" that are gonna get you man, it's telling people about your shit. And using 1000w of CFL's isn't going to change that.

gd job none of my non growing m8s know then the other reason i went cfl, is due to seeing other grows locally, i was amazed that a friends cfl grow during veg, under 2 125w cfls kicked the fck outta my 250w hps in size and health, fair enuff in flower it wasnt that great but did get sum tight tasty nugs. i was thinking if get 1000w of them babys then i reckon im in for a very fast veg time and a some tight nugs, and my cfls will have a 6 " intake fan straight frm outdoors blowing over them and a 4" taking heat out. this was the set up also with my hps but during hot days was coming home to temps of 34.c not gd

Give it a try, I just don't it'll work so great. But ya know what, you can always switch to the HPS during flower. Why don't you flower at night when it's not so hot?
If you're fowering during the day choppers can't see shit. They don't even look, the heat radiating from the roof is WAYY too high to have your grow lights effect it.

I would have the 6in as an exhaust and 4in as intake. Don't be fooled my 200w CFL get bloody hot! I have a small fan for each on and a 6in 425 cfm exhaust and two 250cfm intakes.gd job none of my non growing m8s know then
When it's 80 outside it is 85 in my tent (fans on full). At night its not a problem as when I am pumping in air at 64 it keeps the temp at around 74... a little low in fact.
I am having my lights off from 12 to 6, the hottest part of the day is around 3. I leave the fans on full tell about 8 then I turn them down to half power so I dont loose all my heat. In the winter I think I might put another couple of CFL's in there just to keep it warm and get my ratio 70% bud, 30% veg. The CFL part stays cool but it is the internal ballast that warms it up.
With 1000w watts your grow your plants are going to love it. Just don't think that because they are CFL's that they will be cold.

I don't know how I didn't catch that. How powerful are these 6" and 4" fans? Why would you EVER have a 4" exhaust and 6" intake? Sounds like you need a 6" exhause and a 4" exhause with a passive intake. But it really depends on if these are like 6" PC fans, squirrel cage fans, inline fans, can fans. What are we talking about here?
I'm glad someone with CFL's chimed in before you were fooled into thinking that 4 250w CFL's crammed in a hood isn't going to be HOT AS SHIT. It's going to need to be air cooled and it's going to need some CFM.

i thought that u needed to have twice the flow going in the room as whats going out or u are danger of suffocating ya plants, am i wrong wud it be better if i reversed the fans ???? i plan to grow a scrog or lst the palnts so i can get max penetration, my nxt grow is easy rider so my lights will be on 20 hours a day, i really hope they dont get as hot as the hps or i jus wasted loads of money the main selling point was low heat out put, apparently u can put only 4" from plants without burning them. they also had pics to show this in effect, best nt burn em or they can have em back

I did a test. With all my 872w of CFL switched ON and all my fans OFF. I got the temp up to 97.... I could of gone higher but I did not want it to burn down!
My tent is also small, although I have a HUGE amount of air moving through it: because it is a small tent it heats up fast! What size tent are you going to be growing in?
I love my CFL's and I am stoked I went with them. The plants use very ounce of light.

You can put them closer to the plants because the heat is dispersed along all of the surfaces of the bulb. In HID the heat and light comes from a single source so it's intensity is higher in that one spot. Cumulatively you'll still be looking at nearly the same heat.
And no, you need more exhaust than intake. Negative pressure doesn't cause a lack of Co2. It does however make fans work harder and fail sooner. So you don't want too much negative pressure.
Ohh man, with that setup the way you had it wasn't going to vent correctly at all. Try it with JUST the 6" fan as an exhaust first.
Oh yeah, and describe the fans better.

Think about it... if all your fans are taking air out. All you need is a passive intake and it refills the tent with fresh air. I like to have some air blowing in over my CFL's to help cool them. You can for sure have them 4-6 inches away from the plant's and they will not burn them (just dont put them that close when they are seedlings). All I am saying is you need to be taking the hot air out of the room.
Dude you will not regret getting the CFL's. I fucking love mine. I was just surprised at how hot/warm they got.
I would also use 18 6 hours of light. I dont think 4h is enough time to let the plants rest and generate resin.

my outake is a 70w fan that i aquired from a public toilet its big and my 4" is frm hydro store and is run through a cf i also have a reg fan blowing direct on light to cool it a bit my room is 8 ft tall 2 ft wide and 10 ft long here sum pics[/QUOTE]
also a pic of the buds at the mo
i have the fans as i do cos its wat i picked up on here?? am i wrong i cud v easily alter the flow and drill some 4" holes in my wall, but i thought bringing in fresh air wit co2 was agd thing?

Those are some good looking lights
. Here is my advice. Run your grow room for a could of test days. See what the temp is at night and 3pm (hottest part of the day). Your fan you got from the hydro shop. I would use that as the exaust. Just make sure it is being ducted outside and that there is no way is it being suck back into the room. And just see what your temps are if they are above 85 your going to need a bigger exhaust. I would also place a small fan that is blowing air over the CFL's so that you dont get a hot bubble. But your going to grow some great bud with those lights. Just make sure you are not letting it get to hot.

hope so cliddy will do a test run for a full day an night an see wats up, the 4" is my ou take at the mo so can jus leave it as it is , where theres a will theres a way!! cheers for ya advice

Bringing fresh air in for a co2 is actually a bad thing sort of. With co2 the room has to be sealed and levels have to saty around 15000 ppm while lights are on. You can do timed air exchanges but only like 3 in a 12 hours lights on period. I use timed fans and dampers that open and close when the fans are on or off. You want the area to keep the co2 in at all times and if you you do something like keep bringing fresh air in the whole time your wasting co2 and not benefiting as you should. You can do like I said 3-4 room clears then make sure those happen right before a new co2 fill of the room and your good.

and i wont starve plants of air ? do i need to drill out 4 holes then so th 2 to 1 ratio stll applys? also my room isnt air tight will this matter appreciate ya advice jus shame i didngt catch u sooner

I meant in terms of energy consumption man. I found that my bill was less than when I'd used hps in the past. Ballasts are inefficient, costly and give off too much heat. I'm not in a position to dispute which gives the most light penetration, but I've yet to see any significant drawbacks, except that it's maybe taken a little longer to finish flowering than I expected. Perhaps if I was using a whole room I'd have to take a different approach.
I dont get that statement? if you use 1000watt hps ballast or 1000 watts of cfl the consumption is the exact same? A digital ballast runs both mh and hps and has no heat from the ballast zero. Its as cool as the room air temps so no heat there. They also run silent weigh about 7lbs, are dirt cheap and more efficient actually giving 30% more light then a regular magnetic ballast light so they are highly efficient. Heat well i dont get much heat from them so cant really say. The cfls are good to me for lowering costs around my house. It costs me about $40 a month to run 2 600 watt digital ballast on 24 hours a day. I have ordered for my online hydro store a new light though thats nuts. Its a T8 LED tube. They fit regular T8 shop light fixtures but are filled with led lights. I ordere red,blue, and mixed to see how they output and If I like I will carry them...
