I was just curious to know if anyone here has experimented with various forms of light from the spectrum?

No, but from a plant physiology class I learned that a blue light photon (B) will start a plant seed germinating, and a red light photon (R) will stop a plant seed from germinating, or halt it in its earliest stage of germination.

Ex:

R + B = germination
B + R = halted germination
R + B + R = halted germination
B + R+ B = germination

The only light experiment I know for mushrooms is that UV light causes genetic damage, i.e. PF Albino.

Also, indirect light is needed to induce good pinning, which can be seen via Hip’s Neglect (invitro) Tek.

(B)lue and (R)ed light photons.

Light is a form of electromagnetic enery, which is observed as waves or particles. A photon is a single particle of electromagnetic light energy.

Also the info I posted earlier was INCORRECT, it is actually red and far red light, not red and blue. Sorry for the misleading information (trying to remeber something from a 45min lecture a few years back), but here is a link to what I was trying to put into words:

and here is a high school experiment that I also found on the web:

but mushrooms aren't plants,
and spores are not seeds.

In the first link it mentions that blue light effects fungi:

"Blue light has profound effects on many plants and fungi. In plants there are at least two blue photoreceptors, with a hint of a family on the horizon. The blue photoreceptors control:
phototropism - the bending of plants or fungi towards light..."

Here is something else I just found:
