44,000 lumens and 728 watts of CFL's!

[Marc Benson]

I'm obsessed. I admit it. Too bad I have the dreaded "Black Thumb Disease". But the plants look like freaking Christmas trees! Lights hanging all over 'em! Not cheap to do it this way though. Just anal about cfl's.

12 43 watters
4 23 watters
1 40 watt strip
1 80 watt strip

And here's a pic of what that many cfl's look like.

ZANDOR says that you can't add the lumens.

meaning, if you have 10 light with 2900 lumens a piece, you still only have 2900 lumens.. NOT 29000

sucks right.. he explained it.. and aI understood.. but I guess I was lying to myself cause now I just think he is a party Poooooooooper..

YOU HEAR ME ZANDOR!!!!!! you're a party POOOOPER

grrrrrrrrrrrrrrrr

please take a better picture.. that thing is ridiculous

I love you

I questioned some people that are very much in the know on lights and light energy. Here's what they said.

"The whole discussion in terms of lumens is pointless and not applicable to mj, or any plant. Nevertheless, doubling the lumen output in the same space will also double the lux (lumens per square meter) or foot-candles (lumens per square foot).

800w of HPS produces twice as many photons as 400w of HPS. This can be directly measured, there's no need for speculation."

and

"Light measured at the source is radiance. Light measured at a distance from the source is irradiance.

We are primarily interested in photosynthetic photon flux (radiance) and photosynthetic photon flux density (PPFD, irradiance). Other useful units are watts (radiance) and watts per square foot (irradiance).

Lumens are not a useful unit of measure of radiance for our purposes because the lumen is biased to human visual perception. The corresponding units of irradiance (lux, foot-candles) are also not useful."

Go figure. All I know is that if you had one 43 watt bulb in there that the plants wouldn't be as dense. Basically that's what you're suggesting that Zandor is suggesting.

Sorry love but is that from an episode of "Star Trek" I'm sorry Marc but I read that and it cracked me up

Anyway Marc how are Amanda and Stumpy?

Do me a favour Marc, when you grow the next crop just relax, let nature do the hard work and just look forward to reaping the rewards
Marc just look at some of the beautiful pics you have shown me, all the flowers and the trees, all done by nature
I tell you if I lived close by I'd be in there, getting rid of half the lights, all the nutrients and telling you to go and have a beer and relax
Then I'd go to the feild with the horses in, bag up some muck and feed that to you're girls

Please don't think I'm telling you off Marc because I'm not............speak to you soon.......................love mand xxx

Well for one thing it's not really a 'real' photo of what the light looks like coming out of the grow area. I was just funnin ya. ha

Nope not from Star Wars. Just from one of those guys that can't just say something simply. Like some doctors. You ask them what's wrong and they go on at length with very technical and sometimes unheard of terms. Then you say..."What?"

But his point sounds valid. Lumens is a measure of light intensity for humans. Plants could give a rat's ass about lumens as it doesn't relate to what they need. They need the energy the light generates. It doesn't matter how bright it is to the plant. Just so it gets the energy. We could call it "cabumblefuk's" instead of lumens, but lumens is what we've been "trained" to recognize.

But if I had posted the subject of this thread "44,000 PHOTONS!" most people would've posted responses like, "So how many lumens is that?" I'ts what we're used to.

And you can tell me off all you want Mand. Just don't tie me up. Well.... maybe just once.

What happened??? I got lost.. and all dicombobulated

[chisme]

lolo i got lost after the cfl pic

Ahhhh! Marc! My eyes hurts!!!

Thank God for that Marc I thought it "welding goggles time"


Oh and do I regret doing that little bondage post You see I'm a easy going type, farliy liberal minded, nothing wrong with a little bit of fun.
However I knew this guy, seemed ever so nice. I once visted his house and found another side to him
He was totally into bondage and wanting to be humiliated, he had alsorts of restraints, chains, and things I dread to think what they were.
I left in a hurry and told him I was once married to a oddball, I was not about to get involved with another...................just too much for me.

Mind you I do regret not just tying him up just leaving him there


Just one of lifes experiences I guess


love mand xxx

Sorry but I still think lumens are the way to track it.

Yes i too cnanot understand if I have one bulb at 10K lumens and add 5 more, how the resulting light doesnt equate to more lumens.

Also, sure plants done see like we do....but we dont 'see' lumens and we dont 'see' photons either. We see what is rated at a CRI, or color rendering index.

Plants see KELVINS.

Heck I am not gonna write a bood about lumens and photons anyhow.

I just gonna say get your ass some high Kelvin temps CFL and go to work
