I imagine the light levels in a grass field would vary widely by the minute.

lol yes they would prob with all the movement and weather (clouds cover)
but
still within a certain range and were really just looking for an average figure for cubensis conditions as not all fruits will grow in the exact same conditions, grow to same height ect so you would expect a range rather than a set figure. :smile:

Yeah, I guess you could average it out. :thumbup:

Still, just because they grow in the wild doesn't mean they are getting optimal fruiting conditions in the wild.
Not that you are saying they do...just pointing out the obvious, I guess. ~~~> Nature can be improved on.

yes its very subjective and i agree wild dosent always mean optimal but i guess the mushrooms have had millions of years to evolve and adapt with those wild parameters and to grow and adjust themselves and their internal systems to work optimally with those parameters , is this not how evolution works?
but its all  theory and swings and round abouts really :smile:

Yeah, I understand evolution. But again nature can usually be improved on.
Perhaps if they were given the option of fruiting from Brown Rice Flour and
fanned and misted hourly, they'd have 'evolved' bigger and better for that?

The only requirement for a species to evolve is being able to out survive and out reproduce any competitors...
...in a given environment. Change the environment and the whole playing field is different. Thus, you get:

yes i agree and domesticated mushrooms probably have drifted somehow since we have been cultivating them on differnt substrates and conditions.

and giant veg like that pumpkin have been bred to produce specimens like that no wild pumpkin even in the same conditions would never reach that size.
when we select and breed plants we break genetic equiblium and increase gene ratios of the traits being selected. in effect we force and speed up evolution.
its not always optimal conditions but rather genetic pathways and growth responses that are altered to produce such specimens.:smile:

but yes i still agree somewhat :smile:

:nodofunderstanding: We're in agreement.

So, the point of this thread is what are the optimal lighting conditions for cubensis.
I have nothing to add, & am just absorbing the knowledge much as a mushroom w/ light.

By the way my lux meter have 3 settings x1, x10 and x100. My measures where on the x10 setting. That means that what i measured 300 lux units they were actually 3000 lux units. X10 is the channel setting we use to measure our light for our mushrooms.

As van told me, if they grow in open fields, on a cloudy day, they easily receive anywhere from 1000 to 20000 lux units or even more, depending on the day hour, even they may get direct sunlight which is like infinite lux units lol.

Generating 20000 lux units will have a big impact on your electricity bill. If you want to recreate the light environment, you would have to program the light to start at 0 lux units(night time) and start raising the lux units gradually simulating the daybreak all the way to 12:00 o'clock PM (20000 lux units or so) then gradually decreasing lux units simulating the afternoon light all the way to night time. And we are not taking into account the light color spectrum, because in nature cubes don't grow at a fixed wavelength spectrum of 6500K. We would have to automate also light wavelength spectrum.

Too much $ and too much automatisation devices $$. Is a dream guys, cubes grows fine with an average 6500 K bulb light.

The point is finding what is optimal and most efficient to me. If I get 4 oz from a flush with ambient light and 6oz from having an LED over it then it may be worth using an LED. If you only get 4.5oz with an LED though it may not.

There's lots of speculation here.
I'll mostly add that I've found light so effective that I give my tubs a combination of 2 6500k CFLs and 2 blue "party" CFLs and have excellent results for only a tiny additional price (I use socket splitters).  I've also tried 4 blue CFLs with excellent results but mix it up to give a larger light spectrum (which anecdotal evidences suggests isn't necessary as they seem to ignore anything not in the green/blue section).
Addition of UV lights seems to have no real impact on growth but does increase the tanning seen when submitting them to heavy blue light.

When I get around to it I plan to do actual tests on a mono culture, but that's been put off for now.

I'm no expert but from what i've read lux lumens only measures visible light.
Par lumens are actual useable light. So brightness doesn't seem to be as important as once thought. It's the spectrum and the distance it can travel.
Most of the light used by plants isn't seen by the human eye so it could be the same for mushrooms.





unless mush photosynthesize i dont see how Photosynthetically active radiation make a difference??? i could be wrong ,dont hold me too it :smile:




I'm just saying  the light spectrums mushrooms may utilize we can't see with the naked eye. 6500k lights are broad spectrum. We see the white/blue light from them but they also emit reds and greens etc.
The blue white spectrum is the most prominent hence the color.
What the mushrooms utilize from any light may be in the spectrums our eyes can't pick up.

The best way to test is with LED's because you can use specific narrow band spectrums. A certain someone who shall remain nameless lol.. uses 455nm blue to trigger pinning and 680nm red to inhibit pinning.

LED"s are pretty easy to build if you have a soldering gun. The LED's and LED drivers aren't very expensive either. You can find everything on ebay or amazon.

The more light the better i guess. I don't even think if there are fruiting problems related to an excess of light. Unless you use UVc lights and that stuff, then you could get some mutations and shit like that.

Exactly, the only problem I've had with excess light is the heat drying out the substrate, which was an easy fix.

A while back someone posted their P.Mexicana grown under 400 somthing nm light and those Mexicana were amazing. This user had very little posts and is a TC. If I can find it then my post will be more meaningful
