Im using an LED strip; mostly just to reduce fire hazard (house is more of a firetrap than dry kindling)

Ive really been trying to find information about if LED light is as effective as high wattage, 6500k+ florescent. As a biologist, i understand that almost any light spectrum will be enough to set the circadian rhythms, and i know that mushrooms dont do traditional photosynthesis. But beyond the fact that mushrooms use light as a directional source (like most plants/fungi), and that the circadian rhythms need to be set, i cant understand what the mycelium/mushrooms utilize in the light. Are they processing it in a way that higher wattage light would increase productivity? or it is really just a cycle setter.


If anyone had any research material on what processes exactly mycelium/mushrooms use light in, that would be an amazing help.

I should probably post this somewhere else as well. But anyone who has an opinion/preference on light, might know at least a theory of why one is more helpful than the other.

Maybe this info is out there, but wading through 13 year old info i get the general consensus that either LED is as good as florescent, or that nobody really understands it that well.

might lead to a great non-ms experiment....

Search threads less than five years old, using RogerRabbit in the filter.  I've given up all my LED lights and gone back to fluorescent.  At one time, our mushroom farm was 100% LED.  Performance dropped, and when the LED lamps were replaced with bright fluorescent, harvest weight returned to normal.

Mushrooms do not 'use light as a direction source' even though they are phototropic at certain stages in development.  Mushrooms derive energy from light and grow double or more in size and weight when proper lighting is provided.  They orient their caps toward the light to absorb as much as possible, not to 'know which way to grow'.

Natural daylight, or fixtures in the 6500K range provide the best performance at lowest lux.  Increasing intensity of light will increase performance.  I haven't found the upper limit yet.  Mushrooms which were grown near 400 watt metal halide plant lights had the best performance of all even though the MH I had at the time was 4000K.  It seems intensity made up for less than perfect spectrum, although it's anyone's guess which of the many peaks at various nm these lights produce which triggered the desired results or if it was a combination of all of them.

Please no comparisons to plants.  They're totally different and use different mechanisms, most of which can be observed but not fully understood at this point in our study of fungi.

What if you simultaneously used lower wattage lights  or Florescents with LED. Have you tried using lighting techniques simultaneously??

Right now I have 2 5000k CFLs for my SGFC & two 4' 8000k T8's I'm using for monos.

6500k is considered best.

From what I have read between 5000k-8000k will work without much noticeable difference.

I would stick within those ranges though with 6500k being optimal.

The reason I am running the 5000's & 8000's is I had them already and couldn't find the 6500's locally. What I have seems to work great.

some growers use LED to fill in shadows that's about it. most commercial growers use natural light from skylight setups and 6500k florescent, I have seen one commercial grower use LED rope lights in conjunction with skylight. but all of us hobby growers worth our salt use either spiral type or tube type 6500k bulbs at least 20w about a foot away from the grow. the spiral ones should be the ones replacing 100W incandescent.

walmart man.  Get yourself a 4ft shoplight with 2 6500k bulbs.  Throw that shit on a 12/12hr timer and you're good.  like $20 bucks.
My tubs are on wire shelfing so the shoplight is strapped to the shelf above and sits about 6" from the tubs.

Don't necessarily need a timer but this.

CFL,6500k "Daylight" brightness. I got mine in a pack of four for like ten dollars from Home Depot.
Make sure they're the swirly ones.

Edit: IF NOT, you can buy those sticks but I prefer my bulbs. I got a lamp that clips and pivots so I clipped it to the handle on my monotub and angled it down, fills the whole tub nicely.

Good luck OP.

my 4 ft shoplight sits right over two side by side 60quart monotubs.  Lights em all up and directly above.  Light is light but I like the nice clean look as well.

Someone said black light works but I forget the specified spectrum. Anyone?

What cycle do you use, meaning how many hours on and off? I currently get some daylight in the room, wondering if worth the switch to tubes
