Malocan. If you could by chance do a simple test with only a few metering points
Of any difference from a fully reflective area vs anything less.

Fully reflective as in white or silver floor ceiling and walls vs the normal non reflective floor and ceiling. Facing the meter up of course. Just interested to know actual numbers benefit of a high reflection ceiling and floor and walls.

By eye fully reflective ceiling and floors seems super bright. But knowing plants light receptors are only on the top of the leaves I wonder if there's much benefit.

Leaves act as diffusers. There is definitely a point. Any light not being reflected is converted to heat, and that's a real shame. Actually any light being reflected is also converted to heat, just not as much.

Hello,
Yes i will do that test, but i have to say that leaf will be not from weed plant. just from a normal plant with a bit bigger green leaf.
Atm i dont have any weed plants:/

That sounds like too much work. Did you go with Ideal or BJB? Only the BJB focus the light a little. I'm just curious what the footprint looks like without them at all from 24 inches. Maybe they are unnecessary? I have the same reflectors.

Are you typing in that footprint data manually? Or is that something your amazing miracle machine stores for you? I had to do some copy and pasting and searching and replacing to get it into excel.

less blue and red, all sucked up by chlorophyll a and b
minimal change in far Red. leaves are transparent for this wavelength
also less green but this depends on the number of leafs between the light-source and the sensor

That's what charts I saw looked like online. Here: http://www.edaphic.com.au/knowledge-base/articles/light-articles/spectrometers-reveal-how-plants-detect-their-neighbours/

But I'd still like to see it done personally, because @Malocan has an awesome new toy to play with. I'm sincerely jealous.
