HID vs CFL

[JackdaWack]

Your asking rediculous questions. what do you want to know? in simple terms. What light spectrum to use or as an ass hole would state, what par levels to use? lumens are given by watt.

[Shallow Hal]

dunno about cfl's but the 600 watt lamps i use produce 95000 lumens each . thats alot of cfl's

[Volker]

your missing the point, a cfl will never be as good as an hps for flowering,

You're missing the point as well, I think. There's no argument that MH/HPS is superior to CFT for growing.

The point is that CFTs are excellent in tiny, enclosed spaces where ventilation is an issue. Very stealth. Try putting a 150W HPS in something the size of an office copy paper box. You can easilly put 150W of CFT in there. You won't get the same results you would with a 150W HPS, but you would get results.

Again, I must stress that HPS is the "tried & true" light of choice. Superior for growing in a grow room in every way. But it just ain't gonna work in a "shoebox" without major hassles.

I agree, this seems like a circular argument. I've grown one plant in a 1x1x3 foot space with 5 CFL's and honestly yileded fined. Take into account it was 5 motherfucking lights for a tiny little ass space, so I better have yielded something descent. However, if you're thinking of growing anything more than that, in a larger space, I'm agreeing with these fellas, HID is the way to go. I understand they may be initially expensive, or depending where you are, hard to come by, but if you're seriously interested in cannabis propogation, than you should invest. Again, personal choices, you definitely can grow fine with CFL's its more like the difference between making 9 bucks an hour or 20. You probably are gonnna have to work a bit harder but they pay off is obviosuly better (i realize this is a subjective analogy). Anyways, HID's the way to go if you wanna grow pro. and as for PAR, seems irrelevent to me.

Volker i stated that aswell in another post in here. I dunno what answers this kid is looking for. I mean he went from hid vs cfl to par levels(light spectrum). I stated above that if your space is small and no great ventilation then a cfl will work and will give you results, however an hps is far superior if you have the environment controls.

i mean this kid comes in here copy pasting shit off wikpedia, making abselutly no sense, and i dont want kids coming in here getting false information on lumans and light spectrum colors. its so stupid i told him to drop the whole matter because it was irrelavant and hes gone on to wikpedia thinking i know nothing. Any one whos taken a chemisty class knows this stuff with out a complicated explination. Lumens = power of light. Par = range of light plants use(visible light), which differs from veg and flower. But no one talks about PAR they reffer to it as the light spectrum. To answer your question in the beggining hagbard, if you want potency density and better maturation time, get a hid system. 20 cfls will not run cooler, maybe 5 of them will, but i have herd of people with cfls having problems with proper ventilation. plus instead of worring about one light burning your plant, you get worry about 10+. And to answer his question on par levels for cfls i belive cool white contains all levels of light, PAR. Warm white, contains more red spectrum, The higher par levels.

Volker i stated that as well...a cfl will work and will give you results, however an hps is far superior if you have the environment controls.

Bleh! Soory, missed that. Guess we on the same page, then!

hehehe... When I salvaged and mounted the squirrel cage fan out of a trashed microwave, my closet temps shot down from high 80s to upper 60's. I only run the fan if I notice the temp in mid to upper 80's. I think I may have enough ventilation to put a small HPS in there. There's a few 75W to 150W HPS "security lights" I can "snag" down the alleys...

Only problem is, it vents into the kitchen. Right now, with CFTs, I can defo smell it when I walk out of the entry foyer into my apt. If/when I go HPS, I imagine that smell will only get worse. I still have to find another chunk of pipe & elbow to vent it to the kitchen exhaust, which vents to the roof.

[canuck grower]

Oh man, I never even thought about the kitchen exhaust! I'm in an apt too and if I can figure out a way to live without a stove for 2 months I'm going to consider moving the stove and setting up a flowering box there. I would have to get a microwave...

well if i can manage to contain the smell in my bedroom this time that might not be necessary, so I guess I'll find out in the next 2 months sometime.

a standard 400 watt hps bulb will put out 50000 lumens initially it will drop some with use wich is why it is changed out well before the end of its life span, you have the same problem with flouros they lose lumens with use also so dont think you have any advantage by using flouros instead of buying one bulb to change out in your hps, you will be buying however many flouros you may have to change out to as maintence, well before they burn out just to keep the lumens up.

thats basically the conclusion i finally came to. cept i found a nice 600w digital HPS-MH combo with bulbs, reflector, and 15' cords... problem is its 300 miles away, it'll have to wait for a road trip i guess.
