According to the latest brochure from Paul Stamets, he says that scientists don't yet know the exact mechanism that mushrooms use to turn light into energy, but they're all in agreement that they do. A normal day/night schedule works far better than 24/7.
Light becomes a pinning trigger when there is full colonization of the substrate, high humidity, and a loss of moisture from the substrate due to fresh air exchange. Provide all of the pinning triggers and you'll see stellar results. Use light in the 5,000 Kelvin to 7,000 Kelvin range for best results. Bright light has proved far superior to dim light. RR

Works better specifically for pinning, fruitbody formation, sustaining vegetative growth, or all of the above? I suppose it's time my cat set up a timer, cuz he's too retarded to remember to switch the lights manually.
The mechanism by which they absorb light isn't known for certain, but there seems to be a lot of interest in melanin in this regard.

So if I wanted to do an experiment, one monotub with light one without, all other variables controlled for. What effects should I expect on the tub that fruits in complete darkness?

Fewer fruits, uneven pinset. Uneven growth, sometimes in odd directions. Lower overall yield, and less spectacular individual shrooms. That's what I'd expect.

Really? 5500K won't cut it at all? I have a 5500K bulb, do you believe it wont be effective at all, or just less effective than the higher temp colors?

5,500 Kelvin will work fine. Once you get above 5,000K and below 7,500K, the difference is minimal. The important thing is not to use incandescent light bulbs, which at 3,000K are too 'red' to be of much use. RR

Sweeeet. Hey whats the deal with lights and lids and stuff. I mean, could one grow in a closet where the light is like 4 or 5 ft. above a container with a translucent, plastic lid? Plus, what if there's a translucent glass cover on the light? Would one lose color temp or important light waves in this situation, or anything like that?

Here's a picture of the growing area in my underground mushroom farm, now complete. You're looking at ten shelves, each nearly 20 feet long and 3 feet wide. That's 400 watts of LED 6500K light rope stretched out over the 200 feet of shelving, for 2 watts of LED per linear foot of shelf. It's bright as daylight in there, although the picture really doesn't do it justice. There's room for 500 substrate blocks, and the temperature stays a steady 58F, even when it's 100F outside.
The rocks on the floor are for humidity, much as perlite serves that purpose in a terrarium. After spraying the rocks with water, humidity stays at near 99% for up to a week. I ran a water line to the farm and installed a faucet right in the growroom, so spraying the substrates and floor/walls will be easy. RR

!!! That's quite a sight there.
So the LED's are working out for you, I take it? Do I remember that you are powering this off solar? Or wind, maybe?

WOW. that's just bad ass! you said that the mushies absorb light energy is there a limit to how much they can absorb? is there a point where it starts to become detrimental to the mushies?

is the 58F like mid ground temp for all the mushrooms I'm taking it there is more then 1 kind growing in there...

How about the LED grow light panels? They are in the 460-470 nm Blue spectrum, is that ok to use with tubs?

58F is the ground temperature in this area(and most areas) year 'round. With all that steel in ground contact, it keeps the air at that temp, which just happens to be best for shiitake, maitake and oysters, my three main cash crops.
More light is better than less light, provided it doesn't heat up and/or dry out your substrates. I found a few years ago that a few minutes of direct sunlight each day works wonders for stimulating massive pinsets and have been recommending such since then. RR

Thats a really nice setup! I just hope your LED lights dont discolor and change the light spectrum. They are known to discolor over time.
I have seen some really neat solar powered LED light rope that lasts over 9 hours per day. Would be of great use to someone who doesnt have a power supply nearby.

Up until this summer, all I had was solar panels. The co-op finally ran power lines up here as part of the economic stimulus package so I actually have utility power now. I originally ordered all LED so I could run them on solar. RR

On the subject of light, will adding an additional light in the yellow spectrum to help w/ photography have any kind of negative interference on the daylight spectrum bulbs? I don't like how blue the photos turn out in the growing area and want to add a bulb in the 3500 range.

Just add a growlight in addition to the blue light. It uses all colors of the spectrum, just like the sun. I figure since mushrooms have been using the sun forever, why not imitate it?
