I use to hear about people giving their plants beer. I have tasted bong water and i dont think i want to grow up on that shit. I also heard it was good to feed it egg then crush the shell up with it.
No, there are plenty of facts available. What you want to study is Horticulture, plant biology. Black Lights are called black lights because they put out only a small amount of visible light. The rest of the light is in the non-visible range and it's called Ultra Violet. This is the light that causes phosphorescent materials to glow, your body to produce melanin that causes you to tan, and photosensitive polymers to harden. What it does not do is aid in plant growth.
Plants take in water, oxygen, and nutrients through their roots. If you watered an orange tree with orange juice, how do you think it would do? Do you think the oranges would take in the extra Vitamin C and become super-C charged? No. It doesn't work like that. Besides, try pH testing some bong water. It is very acidic, to the point that it would adversely affect a medium such as soil that acts as a pretty good pH buffer. Not to mention all the other ick in the water. Plants do not require any of these ick nutes, and if it doesn't require it in one form or another, it's not going to absorb it. It can only act adversely here.
No, these half-baked theories are ridiculous when you take the mysticism out of it and apply a bit of simple science.
