Right im getting pissed about The FLUX

Dude.. don't start this shit again.. The lumen rating on your bulb is specific for it's color temperature (kelvin), so if you're using a 2700k (warm) that is 1000 lumens, it is, wait for it.. 1000 lumens of 2700k light at the surface of the bulb! Light meters can be calibrated to show the luminosity of any and all color temperatures.

yh i hear you thats what ive been saying you cant base your facts on a lux reader
The what would you base your facts on then? There is no other way to measure light than with a light meter. Luminosity isn't based on individual perception, photometric units are precisely defined and precisely measurable. They are based on an agreed-upon standard luminosity function which is based on the measurement of many individual eyes.

THIS is a good point. A lux meter is NOT monochromatic. The meter and our eyes may be slightly tweaked for green, but damn man I see red an blue just fine. The meter is just peachy fine. If you want to tweak the meter for the red and blue, add filters.

where do people keep getting the idea that using cfls is efficient.......they are way less efficient than hid...period.no buts or if you do this....thats it ,hid is the most efficient and less expensive lighting to run.....and packing 20 1000 lux cfls into a room doesnt give you 20,000 lux..it gives you 1000 lux that can cover a bigger area...but now you have a heat problem , because yes cfls get hotter than shit when you pack them all together..400w of cfls are going to be the same temp if not higher than 400w of hid......if you are growing one plant in a rubbermaid or something like that cfls can be to your advantage...but thats it..and even for one plant you need about 6 23w cfls positioned to encase the plant giving it light from all angles...and now you are using 138w when you can get a 70w hps from home depot for around 30 to 40 bucks and have much better results and use less energy and have less heat aaaaaaaannnnnd...its much cheaper....period.........

Ok yh i know but heat not and cfl are kinda shit but if you have the right ammout they save alot of money but
My main point is that
You Cant Base Your Facts Talking about something which is metal when a plant is bio.
i know you can only get one light intensity per a type of bulb but i plant doesnt just read (eat) what eva you wanna call it light intensity they must be more to it.

So by your logic, camera's don't "see" the same thing we see? They don't record an accurate image of what you take a picture of? They can't be trusted to provide facts? After all they're just glass and metal.. plastic and shit..

Hey ONETIMEONLY i have news for you lumens dont ass up.. If you have 5 100wcfl's in a reflector, and another plant under 1 200w cfl with its own reflector.. the 2nd plant will recieve light much better at the top. Now the only advantage of the 5 bulbs is it can cover more are but no area will be as good as the area directly under the bigger cfl. Just read the growfaqs and get your facts straight instead of trying to find a loopole where lumens add up lol. it doesnt exist

I just LOVE the metal vs bio thing.

I'm sure hes all on the lumens spec, but they were 'measured' on that same 'metal' meter

Now, what metal? Cadmium sulfide?, Selenium arsenic? Selenium teruliuim?
( a few SPs there)

Funny. Some things might respond similarly to the same stimuli applied to them. Hence a baseline for measurement. Kinda like a thermometer. I don't have mercury running through my vains, but I can feel a temp change.

And hell my eyes ain't 'metal' either.

wow fellas,
i'm still way new to growing but your discussion definently helped me out, especially the sun reference.
so bare with me here, AlphaNON, what youre saying is by adding more bulbs of the same lumen out put DOES NOT increase the lumens the plants are recieving but DOES increase the light distribution of said lumens??
is that kinda the jist??
thanx bro

That's correct. It's why buying a 400w 50,000 lumens HPS is a better idea than CFLs...I still did CFLs for my first grow, I dont really care :)

I'm not trying to discourage anyone from using CFL's, this discussion started out about all types of lighting. I use CFL's myself for clones and side lighting in shaded places. They have their place and are great for micro-grows, first timers, single plant setups, hard to vent places, bag seed experiments etc. But I hate to see people spend hard earned cash for exotic seeds, and then use CFL's with the belief that 10x 40watt 2,000 lumen CFL's will be equal to a 400watt 50,000 lumen HID. It's just not true, you're not saving any money or electricity, and while you might see good results in the way of flavor and quality, your plants will never reach their full potential under lighting that is merely a (figurative) match in the dark compared to the luminosity and intensity of the sun.

This dog was already dead before I started beating the poor fucker, it needs to be put to rest until compact fluorescent technology has progressed to the point that it can produce at least 100 lumens per watt.

THat sums it up. You won't get more then the most lumens bulb, but if they are all the same you can have that intensity (aka:lumen #) everywhere if set up right.

Trying to save a few bucks?

Get a HPS (MH are best for vegging and HPS for flowering.) I smoke flowers not leaves, so my money would be with HPS. HPS does fine veg state and MH does ok in flowering.

Got the cash? Get MH for veg and HPS fr flowering.

i just wanted to add something about 70w hps. i have a closet-type grow op with aprox. 20 square feet total so heat is an issue in my un-airconditioned top floor apartment. I have known for years that HPS is the best choice for lighting but the standard 150w-400w hps being sold at grow shops was just too much heat. So i went to a country store (home, garden and farm) to look for a low wattage hps. to my surprise i found two hps bulbs one at 35 watts and the other at 70w. i got the 70 watt one and looked for a ballast or some type of unit or fixture with a ballast but couldnt find anything. i then hesitantly asked the store clerk if they had ballasts for them. to my surprise he told me they do not carry any ballasts(other than florescent) and that a 70w wouldnt need a ballast because the watts were so low :confused: dumbass. anyway i bought the bulb for about 30 bucks including tax and went on my marry way. i the came home and scoured the internet looking for a 70w hps ballast to buy from canada (i dont trust borders) and finally came across one from home depots industrial supply building. with shipping and taxes it came to about 80$ which i thought was a rip off,, and that was for an unwired ballast/ignitor/cap with no fixture. little to say the wiring was a disaster,, there are so many fucking random wires coming out everywhere it seems impossible,, you have to know how to read wiring diagrams because it is nearly impossible to find a "for dummies" instructions on how to wire the exact ballast you have.

so im shhhabaked right now and totally forgot where that whole thing was going,, i guess what i was trying to say is your best bet is to get an air-cooled 150w minimum (for one big or two small) HPS for your op,,, fuck that CFL shit,,, people hail CFL for it low temps but what i think they dont realize is that its the bulb on the cfl that creates nect to no heat,, the ballast,, which is mounted on the bulb creates the heat... with HID you can mount the ballast externally to reduce on heat.

p.s. i still have to keep a fan on my 70w ballast to keep it safe to touch

and thats the end of my senseless, sporadic, stoned thinking

I got a 70W hps secuirty light from Lowe's for $30. Bulb and all Took apart the housing and mounted the ballast componenets on to a board. viola external ballast. just wire it up to an extension cord and go. And the ballast barely gets hot compared to the bulb on an HID. It'll burn you

without that 12 v comp fan screwed in away from the wall the top of that ballast would burn you.
i cant believe you got the whole deal for 30$,, we dont have lowes in canada... it would have been a little cheaper but i had the ballast shipped because nowhere had one locally. i ended up spending over 100$ by the end of it :(... but IT IS BETTER THAN USING 2 OR 3 45 WATT CFLS... in my stoned opinion...
