What are you not sure about? That the wall reflectance increases the beam angle from either 90 or 120° to 180°?Not sure about that one, my par meter reads different numbers at different spots of the tent, especially if I'm up close to the lights and down lower, different readings.
The center hotspot is there due to this place receiving a higher amount of crosslighting. I'm not doubting that but what I doubt is the correct application of the inverse-square law with its standard false interpretation that energy/photons just miraculously disappear with distance. (see quote in post #38 for context)Hot spots are present when you get different reading at different places
They don't disappear they are reduced, it's common sense.but what I doubt is the correct application of the inverse-square law with its standard false interpretation that energy/photons just miraculously disappear with distance. (
This ^You need to be able to fully saturate that substrate to run off.
Is it “intensity of light” or is it photon density? Or are we talking about the same thing?However, the intensity of light is inversely proportional to the square of the distance from the source, so plants twice as far away receive only one-quarter the energy. (The Inverse Square Law)
How did lighting become such a complex subject here...lmfao...Jesus Christ .....Is it “intensity of light” or is it photon density? Or are we talking about the same thing?

Good luck with your grow @cabinetmaker74Are you done cursing and being disrespectful trying to kill an otherwise informative discussion?
My 7 g pots go thru 1g of water every other day.Holy crap only 3 cups.. My plants were drinking 12 cups every 2-3 days in 7gallon fabric pots
The photons don't disappear. They spread farther apart, i.e., the density decreases. I think we can assume the number of photons emitted is constant. It's the density of photons as a function of distance from the source that matters. I agree that this doesn't account for the reflection from the sides of the tent or the effect of items inside the tent. Speaking of which, I noticed that light measurements are affected by whether the tent door is closed or open. For that reason, I close the door as much as possible when taking readings.The center hotspot is there due to this place receiving a higher amount of crosslighting.

That's about what I use for my 7-gallon pots, depending on the growth stage of the plants. It's usually 3 or 4 days between watering, though.My 7 g pots go thru 1g of water every other day.
420 picoliters 420 times a day. I grow in thimbles.My 7 g pots go thru 1g of water every other day.
