yes i do. never thought of that.
gonna have to go to a full shade 13.

just one question though, if light truly is additive, then why does my torch not make the slightest bit of difference during daylight hours outside,

You mentioned daylight... which means the sun, and it's several times brighter. Kind of like the difference between a 99 MPH fastball and a 100 MPH fastball.

i can't see that as i don't have java installed nor do i intend on installing it.
you just stated "You mentioned daylight... which means the sun, and it's several times brighter. Kind of like the difference between a 99 MPH fastball and a 100 MPH fastball."
if light were additive then how is that the case, what your saying in this sentence is that its only as bright as its brightest source, a weaker source will not make it any brighter.
if that is the case how can 2 cfl bulbs of 1000 lumens each or whatever make the intensity twice as much, surely if a torch is not bright enough to add to the day light outside then light can not be additive in the manner in which you are describing

It's not that the torch does not add to the brightness of the day. It in fact does, just on a scale you can't notice.
A torch hardly lights a dark room...

It does add, but as I said, it doesn't compare to the sun. You're adding a penny to a dollar(or whatever, you still do not have enough for a Bic). Your perception of it doesn't register the change. It's not multiplicative unless both sources are equal in lumens, and equal in distance to a leaf.
If you take two lights and put them near each other, you'll notice they create shadows from one another. Then compare that shadow color to the brightness around it(that's receiving light from both sources). You'll see the difference.
Again, do you even use a reflector? Your line of reasoning would render them absolutely useless in this alternate world you apparently live in.
And flashlights.... Those obviously also do not exist in this fantasy land. You can also not cook ants with a magnifying glass. Seriously? This is where you're taking this with your line of thought.
Which is why I typically just stop responding when people get this 'out of touch with reality'.

your obviously taking this as some sort of attack on your knowledge, why can't people debate and discuss anything without getting trying to beat people down.
there is clearly a massive difference between cfl and hid, i know this first hand from experience
you can show me as many charts as you like and whatever proof, but the proof is in the pudding not in the instructions on how to make it
read back over this thread and i haven't bashed cfl's, but they are not now and nor have they ever been equal to hid lighting.
I agree you can get some satisfactory homegrown results out of a cfl that guys like you are clearly more than happy with.
i'm not saying they are rubbish, i'm just saying they are not on the same level as a hid lamp no matter how many you use and how many total lumens you achieve you will never get the fat dense buds with cfl that hid provides

I thought your concern was that light is not additive...?
We only tried explaining a handful of times... Forgive us for getting aggravated.

It's an attack on common sense. Which is so rare is a fucking super power.
This has absolutely nothing to do with any light type versus another. I think they're all just great.

No not really, i've seen this guy tea tree around a little and I was just seeing what he knew, all i did was question, i never expressed my opinion on that all i was doing was testing the guy to see if it was knowledge he had gained himself or if it was just something he half read and had nothing to back it up.
My words were not offensive i didn't attack anyone and no point did i call anyone wrong

Really? Baseball is so boring that I forget sometimes that there's ANYTHING moving upwards of 10mph involved in the game.
I do like the game of baseball, I don't like the 6,000,000 games/yr they feel are necessary. Who can follow a sport that can be played in double-headers?
Too many games that take too long.

just for the record though, the simplest way to prove that light is additive, without all the science to try and baffle people that don't understand what the hell you are talking about is if you have two hid lamps together, you can physically see the light reflecting back off the wall, and you can see how it increases, where the lamps overlap you get a triangle of increased light on the wall which is visible to anyone.
This is why i will use 2 x 600w lamps to flower 4 females

nice contribution there vaporbros, i'm so happy that was your 800th post, at least you made it count for something

Light is to some extent additive, but it doesn't seem to work in the practical application of CFL's. The intensity still diminishes far too quickly outside of the optimal distance.
If it were "truely" additive, this wouldn't be the case. The light would become "brighter" and therefore the degredation would be similar to an HID.
Maybe the answer lies in the right kind of reflector that can house multiple CFL's in a certain type of pattern. I don't really know, but I know that what we've got now doesn't work and doesn't appeart to be "additive" in the sense of growing marijuana with them.

yeah since we all judge other people by the # of posts they have...... Mr. 71
i added just two 23w CFLs to my flower cab and i can notice a difference. The whole cab lights up brigher and i can see more light hitting the plants. Im also running a 150w HPS

I added 3 68w CFL's to my 2 400w HPS's and you can see a difference because of the light spectrum, not the brightness.
But, I ended up taking 2 of them off because the reflectors I had on them blocked my HID's too much and it was counter-productive.
I left one because I happened to come across a way to mount it where that's not a problem.
I was going to find a way to mount them without reflectors to use the other 2, but then I thought about it, it's like throwing sand at the beach. They already have HID, what was I thinking?
