lol this is some funny shit... OP ...I see your question as a theory question ..and i understand that part .... I see you have an incan that is stateing it falls within the spectrum range for growing ....Your actual question is Valid so far ..... Where it all falls apart is this ....Heat vs output .

CLF's run cool ... cheaper ... have the CORRECT spectrum needed and are the answer to most peoples prayers , You say your going to use CLF ... Good Choice .... If you want to test your theory ....now is the time to do it ... and then show the results , Grow one under CLF ..and one under Incan .... and update the progress of both .... including temps ... light distence from plants .... and enargy bills

I look forward to the results ... Good luck .

I myself intend to try the sun poster thing ...As funny and as idiotic as it sounds .... i have a therory it might work ...and no im not kidding Cowboy :)

See guys ... this is how you deal with it :)
i lol'd so hard reading through the rest of this thread since i left.

i cant believe after some said they grew under incan lights that this argument still went on..

from what ive gathered it is possible but the amount of heat an inability to put the bulbs close to the foliage make them undesirable, not that they are in the wrong spectrum and that bullshit.

now on to Ventos suggestion:
i would love to test my theory but my space constrants make it impossible unless i get rid of my cfls, which would be a waste as i just spend alot of money on them.

but damn i didnt mean to start a fued on this forum so lets all just chill, im sure one day someone will try it(and someone already has) and the results will be presented and HOPEFULLY we can accept the results and not argue over it

actually the street lights near my work are 400s but maybe on the main streets and e-ways their even bigger. maybe 1k idk.
How do u steal a street light? thats very ballsy and like some one said i think there hps or mh Now ..AND someone said they cost more than cfls..i can get a shitty incandes..from the corner store for 75 cents it cost more 2 run tho..I HAVE A BETTER QUESTION ..WHATS IN THE CFLS THAT MAKE THEM MORE EFFICIENT THAN THE INCANDES. IS THAT PART OF THE REASON THERE SPRIALED?

They (CFL's) contain Mercury which reacts with gas in the tube when a electric current is passed through.. they also require less electricity to start the chemical reaction as opposed to burning a thin piece of wire contantly in a candescent bulb.. that's my understanding of the difference anyway

when i was a rookie smoker and kid i tried incandescent and they are fucking crap. your will get a very long skinny stem with 2 sepal leaves and 2 pot leaves. then it dies. trust me, dont even try it you will waste your time.

go HID preferrable MH for veg and HPS for flowering. T5s are good too but HID is best.

thats what you got. i had different results. i was able to raise a bushy plant that looks similar to what i grow under hps now.

Using Nothing but light bulbs?

No window light or any other type of lighting was involved.

i just read only the first page of this, and straight up 10 Incandescent lights put off about 5x the heat as 20 CFL' bulbs. On this principle alone incandescents are IN EFFICIENT enough to not be worth the time and effort to grow with them.

This being said, the first ever time i grew cannabis indoors i used one 75w incandescent light bulb. The plant grew, but it was way too fucking hot so i finished off the grow with CFLs'.

Also, they put off Lumens comparable to CFLs', but they also use 7-10x the wattage to do so.


So bottom line is, Incandescent lighting for growing cannabis is in efficient and not worth the time and effort.

lumens is a measurement of light energy at source which arent cumalative eg 50 lumens + 50 lumens is still only 50 lumens.(at source)
but what we're interested in is the light intensity at a given distance which is measured in lux or footcandles, which are cumalative eg 1foot away from 1 candle is one footcandle, 1foot away from 2 candles is 2 foot candles and so on.
so 2 bulbs, although the lumens dont double, are still "brighter" than 1 because the lux or footcandle has increased.
this is my take, on my google research, which could be wrong but would be delighted to be corrected by someone who actually knows their shit. and not someone who just reads posts and think they know their shit. wrong info is also not cumalative ie. just cos 10 people tell you the wrong misinformed shit dosent make it any closer to being correct.

lol that might be the most hypocritical comment ive ever read

o and btw Oneton footcandles are lumens per square foot so if one increases shouldnt the other one?
"lumen" is the unit of total light output from A light source.
"footcandles"/"lux" are units to indicate the density of light that falls on a surface.
( these are totaly different terms)
so if you had two 50 lumen lamps beside each other you have 50 lumens from two sources. you've increased the number of sources yes, but as "lumen" is the unit of TOTAL light output from "A" light source .what you have is still an output of 50 lumens but from two sources . at no point are you increasing the light output from "A" source
the footcandles/ lux (or the density of light on a surface) WOULD increase where the light from both sources overlap as it is recieving the light from two sorces...
hope this makes sence. like i say, its just my take on the shit i been reading, from proper sources not posts on forums.

To try to explain it further, lumens is a very specific spectrum of light (same spectrum as LUX, which was fairly well explained above). It is meant to measure the amount of human visible light, so it's what WE see as light, hence how bright WE see a source of light as being. Plants don't see the same spectrum as we do. In fact they see a spectrum 2-3 times the range we do, and they need that spectrum. Specifically lumens is a measure of yellow and red spectrum, plants need a range covering everything but green (this is why they are green, lol). There is a measurement of light intensity similar to lumens called PAR (photosynthetic active radiation), which rates the intensity of the spectrum plants require, and if you look at those bulbs they might be 1000 lumens, but only produce 100-200 PAR (if that...).
