hydrofarm 200 watt cfl fixture

I'm looking at a Hydrofarm 125/200watt cfl grow light to put in a 3' x 3' x 3' closet grow..anyone use this light or one like it??just wondered if it was worth to buy or should i keep going with my 10 42 watt cfl's....if i were to buy it i would still use some of my 42 watters for side lighting...my first grow i did 2 plants under 10 cfl's 42 watts and it worked out okay for 1st grow got little ove 1/2 ounce for 1st time not using nutes and using bagseed...do you think this light will help?

it is about lumens not just Watts. What is the lumen count

on a 125 watt 2700 k is 12800 lumens

And a 200 watt 6500k is at about 16000...

I'd say go for it....... a 42 cfl I think has something like 1600?? I think the single fixture would be less of a hassle but you should deff. keep some of the 42s for side lighting. it has a reflector too right? looks cooler? haha

thanks for your opinion...i think i'm gonna buy it..just wanted some info from some people who have expierience with cfl's...i would go with MH,HPS..but the space is small and my wife is freaked out over heat issue's..and we want to keep it as stealth as possible...hey if i can grow a couple of ounces every 3 months with 4 plants that would be freat for us...

that's the ticket. but yeah I've looked at them as well but never had the "guts" to get one. I just think it would save the frustration. of a ton of cfls. and when your wife gets paranoid and whatnot, simplicity= no nagging. haha I have a gf who tends to worry. shit......... I should take my own advice!

thanks alot guys

if your grow box is well ventilated, i would get a 150-250 hps/mh fixture, it would be about the same price as that cfl fixture. the hps would provide a better spectrum as well. a nice kit: http://www.htgsupply.com/viewproduct.asp?productID=48631

Wow that light is nice...like i said my only prob is heat i want to put it in a 3x3x3 space thats behind my walkin closet in my bedroom the whole space is sheetrocked with insulation theres a door on the 3x3x3 space if i leave it open with fans running hopefully it will stay cool...right now i'm growing with 10 42 wat cfl's and the temp in 78 deg and 45%humidity if i switch to this light i'm afraid the temps might be too much...how hot does this thing get??

150 watts of CFL put out the same amount of heat as 150 watts of HPS

hard to say how hot exactly, if your box is that small then i'm guessing you'd have some heat issues

not true

Thermodynamically, how can this not be true ?

The temperature distribution and maximum local temperature is different but the cooling needed is directly related to the number of watts. And there is additional power that is wasted as heat in the ballast to figure. CFLs have the ballast attached. The HPS/MH has the added advantage of placing the ballast outside your grow area, although not always practical to do so.

Hmmm I just looked and you are using CFL's
That would mean that you HAVE NOT ever used HPS because no one goes from HPS to CFL, NO ONE
How would you know how hot an HPS gets without using one?
I have used both CFL and HPS and they put out the same amount of heat
Usually HPS has one bulb while CFL has bulbs all over the place
CFL's has a better distribution of heat since all their wattage is scattered over the plant while HPS is putting out all that heat from one spot
You need experience to give advice and you clearly have none
Please, before calling me out at least type up something to back your thoughts
not true and a smilie face just makes you look like an ass for trying to call me out

buy it i have one works great and for 60 bucks its well worth it

See now that whole speech was just rude, and incorrect to say the least. I have used MH and HPS, my entire family is made up of caregivers or growers as you frogs would call them. Just because my entire grow life isnt posted on this forum doesn't give you the right to make judgments about me or my experience.

The hps will produce significantly more heat, that's why people use cfls to begin with. The best tradeoff between heat and light intensity is T5 Ho, cooler than cfls and midway between cfls and hps in intensity.

I actually run both a 400W MH and a 400W HPS at the same time (side by side) and can confirm that the HPS runs noticably hotter.

That said, a 1000W MH should still run plenty hot. You'll probably need some kind of cooling if it's not in a well ventilated area.

in conclusion
your a jerk
and should never talk to fellow stoners the way you did.
some nerve

you can grab the 200 watt hydrofarm (the BIG one), it will be warm to the touch but not by much. if heat is an issue, you can set up a small box fan to blow on the lights and circulate the air
In fact, I have to heat the room every now and then!
If you trelise and tie down the ladys, you can get quite a canopy. two of these large cfls are quite the light for small rooms. I have six ladys with two of these lights hanging in the center of a 2 1/2x2 1/2 shower. pinching and training helps kept them small but spread out
the stadium SOG, with the cfl hanging in the center, without the refllector, is the best option I've found to get the most use out of these lights.
I'll post a pic of my set up after I get a photo

they just went to sleep
this is just the funniest vomit face Ive seen!

these lights are hydrofarm full spectrum daylight 200w.
thay take a mogul socket and consume 200 watts each, lummen count (I think) is about 16000 each. keep them close and you should get deasent density out of your bud. the lack of hot bulbs alows for the light to be closer and not need light vents
the cfls can be 2'' away and not burn the plants
by hanging them in the center of a small space alows you to have more plants around the lights and you don't get as much unused light. I recomend air cooled hps's for a proper room, but if space and light vents are not an option, CFLs the way to go

these ladys are a week into flower. the 2 along (sour deisel) the wall veged for a month, the 4 c-4s on the bottom veged for 2 weeks. training them to trelis and run along the floor makes for a desent yeild and saves room,

these CFLs kick some serious lummens.
warm to the touch, but ain't gonna burn the shit out of you or your plants

Maybe with metal halides or hps's, the watts can give you a rough idea for cooling needs
Watts are a measurement of energy
Heat is another form of energy. If the light gets hot, there is a wast of energy


I understand the ballast can generate heat, but its nothing compared to an hps ballast. 90% of the light, 20% the consumption, and 5% of the heat= great for a small room
while the large CFL light is in full operation, you can grab the bulb
I would pay to see someone do that with an HPS!
