hey..
i bought a 250w CFL light from $35 from someone selling at canplant.
Cannabis Forums Message Boards - Marijuana Growing, Medical Marijuana, Cannabis Club, Dispensary, News RSS Feed - PLUG & GROW CFL 250W LAMP BLUE - 6400K CHEAP! LAST STOCK : Classifieds
the light is very good for my growth.. i use it with my 250w hps lights...
i wanted to know if i can test the lumens on these.. cuz maybe he is selling it cuz they are crap?? not sure.. i need to test them.. how can i?
Look at the wattage of it and google it. I believe I have a link below on lights and lumes.
yes.. thanks.. check used your linksQuote:

what will the temp in Fahrenheit will be for x2 300w CFL lights? i am havin probs with my 600w hps + cooltube.. too hot.... do you think i can achieve 80dF with my new x 2 300cfls?
closet (3ft x 4ft x 7 ft high) ventilated with a desk fan too.
Need more info. How are you venting with the 600w HPS? What is the CFM of the fan? How is it setup - does it vent from the grow room into the fan and out of the closet? To where? Where does the input air originate?
You may be able to solve your fan problems without changing your lights.
Killer your best bet is to upgrade you fans. I'd drop the computer fan and get like a 10 to 15inch fan in there especially when running a hps in there. But it's never to bad to have a few fans in there. Were are you exsauting the hot air to? Is it in the same room being recycled? Also at walmart I'd look into a portable AC unit you can get.... They work the charm.
i already had 2 separate holes in my wall leading to the outside... all exhausted air is going outside and i have a tube connected to the hole which brings cool air in...
my extractor that pushes air through the cool tube extracts at 187 m3/h (meters cubed per hour) extract rate.
187 is low isnt it? i want to get the RVK 150E2-A1 which is- Flow extraction: 420 m3 per hour .. but it should very loud! and i cant have it this loud!... i have a silencer too but i think that the device will be humming loud!
Deal with the fan issue. That computer fan just won't cut it. You don't need to get a jet engine in there, just a small inline will do. Take a look at Panasonic Whisperline fans. They make some smaller units that are very quiet and would likely meet your needs. Best prices I've found are at westsidewholesale.com
why are you mentioning that i am using computer fans? lol.. i never said that once...:)
Do you have any ducting going to the holes in the walls to extract the hot air? If you get duct (homedepot it's 2.50 I believe) put 2 of those bad boys with fans on the inside of your growing unit to blow thehot air through the holes you will have better results. Do you hve any pics of your grow area.. It might help leading you in the right direction with the heat issues.

i do... but isnt it risky? the eye in the sky have thermal vision too! if they a bunch of heat coming out, you will get it!Quote:

Can you tap into the chimney or another existing vent? If so, read up on local code as there is a right way and wrong way to do these kind of mods. You want to do it the right way... I'm not all together clear on your setup so it is hard to give adequate advice. It seems you have a grow tent in a closet venting from and to the attic? Is that correct? Can you give us more info on your fan? What is the make? Is it inline, squirrel cage, or other? What is the CFM rating or is that the same as m3/h? I'm thinking it is. Also, do you have a fan controller so you can dial in the speed to suit your needs?
It sounds to me like your fan is under powered or that you are drawing hot air from the attic which isn't able to adequately cool your tent/light.

whats wrong with with x2 300w CFL lights? seriously? around 38000 lumens.. each sq ft will need around 9000lumens.. 5000lumens per sq ft would be sufficiently enough though for optimum growth.. cfl lights penetrate more too..
23w CFL = 1600 lumens = 69.6 lumens/watt
30w CFL = 2000 lumens = 66.7 lumens/watt
40w CFL = 2600 lumens = 66.3 lumens/watt
compared to
150w HPS = 14000 lumens = 93.3 lumens/watt
250w HPS = 28000 lumens = 112 lumens/watt
400w HPS = 50000 lumens = 125 lumens/watt
600w HPS = 90000 lumens = 150 lumens/watt
i see it as, 7000lumens per plant, which means you can grow around 14 plants. i only have 5 plants...
i have A 600w hps which produces 90000 lumens, therefore, i need to have around 10 sq ft of area... i dont even have that... i jumped to a 600w hps as i always buy the best, but forgot to research about it! if i had 10sft of area, i wouldnt have a problem as the heat will spread and extracted..
my grow size is 6sq ft!
Now you can run cfls straight through the whole grow cycle but make sure the cfls are with in 2 inches of the plant tops. Now as you figured out the hps will be way to hot for that room unless you have proper ventilation. But you are on the right track my friend!!
