1000w cfl wa u think?

wat temps u running in ya grow room fletch. no matter how hard i try ,, without having the light a pointless ditance from plants ,, the temps always rocket past 30.c,

Gotta differ Fletch. I have an Afghan goo outside who has hit well over 130. I heard about root-fry etc., but she's fine. If I can find a thermometer that goes over 120, I'll post it next to her flopping in the breeze. Today the shade will hit 107, so the patio glare, direct sun, etc. will take it well over 130. I think the difference is the indoor bulbs are too hot to be too near the plants whereas the sun will never be that near, though may be that hot or hotter. On that note, a friend of mine grows 100 plants at a time using HPS bulbs and he pays $2700 a month in power bills. Yikes!

Kat did you deduct the wind velcity factor and drop the tempersature by that as it may say 120 ona thermometer but just like in the winter wind chill drops the temp it feels if you do it correctly...In my smaller 4x4x6 tents with a single open reflector the temps in those is around 80-82... In my 4x8 tents 2 600 watt lights that I put in cool tubes temps about 70 with fans on and about 77 with fans off. In an 8x8x8 room with 3 1000 watt lights temps around 80-84 with open reflectors or about 74 with cooltubes

also at temps above 90 without high co2 yield,potency and time to finish all take a hit which Jorge Cevantas did a few studies on explaining those issues with places like florida and NM or arizona compared to southern places where temps are aroun 80-85

84 wats that in .c bud isnt it over 30.c

Me personally i cant grow crap outside. I tried and tried everything Put outside is dead within 2 weeks time lol and soil grows hard as hell to me I can vegg a mom fine in soil but grow to finish not so much..I luv aero and hydro so simple easy and clean and fast

oh sorry forgot not all in the US thats F no idea what C would be converted

when i run my co2 at 1500 ppm I like to have temps in the 80-87 Farenhiet range

You have great control over all that. I admire that. I still don't understand why outside temps can go so high and indoors where we're trying to re-create nature with light, everyone tries to emulate 'beautiful' weather temps. My outside plant is in a corner surrounded by light walls with no air movement today. Temp was 120+ out there and desktop weather shows 101. I'll say she'll get up to close to 140 by the end of the day. She loves that so why would it be important to maintain the low degrees inside if not for the closeness of the lights?

Of course you are right when it comes to really young plants and hps lighting, but I think the situation is different with cfls. For example I can put a cfl right up on an even young plant with no problems. I know I've done it, but you could never get away with that using an hps. undisputable fact.

Cap, you're wrong. Just admit it, you're making yourself out to be a deuce.

You keep saying HPS is so much hotter than CFL, and it's just BS. I guy just came on and said using cool tubes HPS can be kept really cool. CFL growers use fans to keep there lights cool. It's the exact same shit as far as I'm concerned.

People keep saying, "well look I can touch my 250 watt CFL, but you cant do that with a 600 watt HPS." no shit sherlock

And finally what's with you getting all defensive about when I first said 1000 watts of CFLs can be just as hot as HPS. Telling me not to put negative stuff on your thread. I didn't think I said anything negative, I just freely expressed my point of view.

I think you just really wanted me to comment on how well you can keep your 1000 watts of cFL's cool. And how you can touch your 250 watt bulb, and you only use 4 massive bulbs. Well good job I dont think many other people can keep 1000 watts, as cool as you can.

That 4 bulb cfl shit is the craziest thing I've seen. You gotta ask yourself what's the light penetration to. I'm guessing hid lamps have way more light penetration than a cfl. Not bashing cfl's either because I seen some nice hydroponic grows with them but most grows I see the plants are so tiny. Anyway good luck

No problemo homie that's what the real members in here do!

I have to respond to this one too. Hilarious.

I love how you gus are trying to make me out to be some big vilan or something. All I did was thank Tom_420 for pointing out that 1000 watts of CFl's is just as hot as 1000 watt HPS.

All of a sudden you guys are talking about negative comments, and what a "real member" should act like. If you guys want to see what a actual disrespectful member of rollitup looks like, look at each other Cap and Sweetsmoker.

Also I want to see a video of someone holding their hand on a 250 watt 6500k cfl for 5 seconds. Your hand will burn. When I grew with cfl's even the 27 watt cfl's felt hot to the touch after an hour on so I can imagine that a 250 watt will give you atleast a 3rd degree burn.

Sometimes you can touch the side of the bulb where the fan is blowing, but the other side of the bulb is usually F'n hot. I dont know what's with all these people saying CFL produce almost no heat. Anybody who's plugged in a 40+ watt bulb should know the bulb is getting hot.

Also just because you're keeping your bulbs cool, does not automatically mean your keeping your chamber cool. The fan can blow the heat away from the bulb and heat will still build up in the grow chamber.
Again, exhaust can be used by both CFL's and HPS to keep chambers cool. But for everyone else, other than Sweetsmoker, keeping a growroom with 1000 watts of CFLs cool is usually more difficult than Cap and Squirtsmoker are making it out to seem. I rest my case

well i can touch my 65 watt cfls with an uncomfortable heat but I also can touch my cool tube with a 1000 watt bulb burning in it all day and the gl;ass is barely warmer then my hand hard to feel the heat.. I love cfls to use around the house to save money so My hid lights can run happy and cost less (-=..I will build one of these reflectors and slap in 4 65 watt bulbs which are claimed to be equal to 300 watt standard bulbs and kind of see what happenes. i have a bunch of 125 watt and 200 watt and 250 watt cfls for my store on orde so will play with those too when they come in...I like expirementing this will be great for vegging young plants and clones though or as corner lighting i believe

wow, you are a freakin DOUCHE BAG !!!

Bar care to put the name of who your comment is for?

hang on a sec mate u came on here talking bout how im an idiot for buying 1000w cfl, you was the one insititng trouble also i cannot remember me or fletch calling u names and i also wont sink to your level and respond in the same manner. if u also bothered to read the thread proper u wud know that i have an intake and outtake fan u twat. goes back to wat i said about people ta;lking about things they dont fully understand, maybe if u had any relevant comments then people would listen to what u have to say.

also mysticclown i believe hps do pump out more photons which is wat triggers the rate of photosynthesis, and u r right to say hps have better penetration. i will be be keeping my plants at 3ft and hoping that the 64,000 lumens of light in my 3ft square room ,that is in the excact p.a.r that the plants require, (AS OPPOSED TO HID THAT HAS ONLY 15% OF SPECTRUM THAT PLANTS SEE) come a close second!! all i need is to bring my temps down bout 4.c and its in the perfect range, which im thinking will benefit the growth rate a bit as well, thanks for ya input bud. and yes cfl bulbs do warm up considerably but they do not even get close to heat of a hps.........

Yea thats true they don't come close to the heat of an hps and 1 good thing I guess about cfl's is that you won't need to configure exhaust ports unless you truly need to depending on the ambient temperature in the room. Honestly I want to see your results using this 1000w cfl and compare it to some 1000w hid grows. Cooler temps all the time may actually knock the HID users out of the ball park when it comes to a cfl that pushes out that many lumens and has that type of PAR. This should be interesting.

cheers mystic i dont think id like to stand up to 1000w hid test though lol, maybe a 600w i wud be over the moon if my cfls cud contest with a 600w hps grow. i am optimistic yet somewhat pessimistic lol. only 1 way to find out though
