Thanks fan. I found a pic of your 25 cob setup on your 1g/w grow thread. I can't see it completely but I think I figured out how to get 18 cobs in a 4x4. Does this look right to you?
X = 3000K
0 = 5000K
X....X....X
...0....0 (these are spaced between the X's)
X....X....X
...0....0
X....X....X
...0....0
X....X....X
This setup spreads out the 5000k more efficiently than using 16 cobs. I'd prefer 16 cobs or less since 18 is a few buck more.
This might be off topic, but I was watching growmou5's take on CRI and he stated the higher CRI come at a cost of producing less light. Even if it gives a higher/better spectrum. Is that why the higher CRI's are used as much? Less light? How does this does relate to photons produced by light?
I'm exhausted so forgive me if this is a stupid q's... i'm brain farting now.
Very nice Graytail. I always enjoy Icemuds stuff. Very interesting. If Im not mistaking I may have started that conversation in the mars thread when I once asked Sara why they dont put just a few green led's in their lights. She said it would do nothing and the plants dont need it.
The science Icemud presented in Graytails post is nothing but pure science. A whole lot of scientific research papers is all he posted. It shows that green can in fact be absorbed better than red or blue for photosynthesis in intense light situations. Nothing but science in pdf from actual scientists from Icemud. He has probably done more research in spectrum than all members of 420 combined.
Yes, I think so. That is one dude that knows his stuff when he speaks. He always has science and proof of fact on his side
No. Just in general how science always seems to advance and contradict what was once fact. From food to space.
Didnt mean it to sound like just your meter man. I meant mine too. Thats why I mentioned that whole flashlight to the sensor thing. Mine is known to be pretty good but still....$500 is cheap when talking about a tool in that area of science.
Yeah, that would be a nice tool to have for sure. I would like to see what its ppf accuracy is with each portion of the light spectrum. Some tools will heavily favor certain parts of the spectrum. Different types of light sources mess with them too. Cool tool though.
