If light is so important
    #21265760 - 02/12/15 07:27 PM (9 years, 11 months ago)

Then are any of you guys using HPS.There is no debate thats it has the best range of lumens to replicate nature.
Im still in the old school mind set that i dont need lights to grow mushrooms.But if you guys are telling me i DO need lights then there is no doubt in my mind HPS or atleast MH would be better then florescent.
how much does it play a factor beyond Genetics/moisture content /RH and /FAE.
would a 1000 watt light be better then a 500??
lights and mushrooms... you guys are crazy.
edit- a lot of albino mushrooms have seem to lost there ability to detect light.(although this is not confirmed science workman has confirmed  the same thoughts)
Is light gona help them?

in regards to albino mushrooms they tend to tip over as they mature, mushrooms switch from a geotropic to phototropic response as spores mature and the cap starts to open.  Something about the lack of pigment in the spores also causes an error in the phototropic response and the mushrooms tend to nod over.
that was what i got from workman
i will let the light discussion be handled by others lol

I've seen a coorelation between light and cap size. Not really like a 500w will produce saucer caps vs a regular flouro will produce half dollar caps. More like a you have light, or you don't.

It's not really like photosynthesizing plants where they NEED light to produce food. There, yes a HPS is definitely superior. For mushrooms energy from the light would be secondary to the nutes obtained from the sub


--------------------
The mushroom speaks: '"I am old, older than thought in your species, which is itself fifty times older than your history. Though I have been on earth for ages I am from the stars. My home is no one planet, for many worlds scattered through the shining disc of the galaxy have conditions which allow my spores an opportunity for life... How the hypercommunication mode operates is a secret which will not be lightly given to man. But the means should be obvious: it is the occurrence of psilocybin and psilocin in the biosynthetic pathways of my living body that opens for me and my symbiots the vision screens to many worlds"

Light is important, especially light in the blue spectrum.
You don't technically need light, but it makes one huge difference!
HPS and MH both peak in yellows and the warm side of the spectrum whereas 6500K CFLs have a larger peak in the blues.
A second issue to watch out for is heat, you don't want to overheat the mycelium, which is why CFLs work well.

If you are looking to experiment with lights beyond CFLs I would look into LEDs, there are a number of threads here about them and LED technology has increased quite a bit.

well only One way to find out for sure. do a test!
1 FC with hps for lighting
1 FC with cfl for lighting
1 FC wIth No lighting
All other growing variables consistent.

then post your results! It Would be interesting to see The difference.

However I Have a feeling NO light When fruiting would not produce much If Any fruIts..

You would need to grow with a monostrain to control genetics.

Cubes will grow without light but they end up extremely lightweight and spindly with tiny pencil eraser sized caps.

You can fruit cubensis in the dark I believe,

Didn't they used to do that before we realized how much they liked light?

Was looking into lumens the other day and found a good quote

The consensus is color spectrum is more important than intensity, which is also not as important yet not irrelevant.

Todays MH are at 6500k

Hps 2100k

Dual arc is both in one bulb afaik

A high output T5's would be better from my perspective. Less electricity used and not much heat. Obviously they're florescent.

Induction lamps look pretty cool though. Expensive but they're supposed to last forever.

They're expensive, but I've been having good luck with OttLite T-20 tubes in my shop lamp.
As a less expensive replacement (7 bucks instead of 20) I bought a Philips full-spectrum grow light, and I'm using one each of that and the OttLite in a twin T-20 ballast.  Seems to still work well, so when the other OttLite burns out I'll replace it with another Philips tube and see how that goes.

I'm also pretty ambivalent on the light subject.  While I agree with much above, I haven't really seen anything cut-and-dry myself.  It's definitely one of the things on my list of things I intend to experiment on.  How would you feel about doing the experiment?  You don't need an isolate for that; ignore anyone who says so.

I read an article some years ago by RR where he found that the strength and the spectrum (and angle? or was that another article?) of light directly related to pinning.

i believe this to be true,  we just have to look at the distance we keep our lights away from the mycelium.

if it was about intensity we would have the lights alot closer than we do!!
anyone who has grown plants with cfls will no they need to be and inch or two away from the plant to be effective.

this is because the lumens or lux level diminishes the further away from the light source you get, and cfls are very poor(pathetic really) at projecting the lumens out over distance.

i predict if someone was to use a light/lux meter in a monotub with the cfl above the intensity at substrate level would be very poor in relation to what the lamp pumps out! and probably equals around the same intensity as shady spot outdoors under the intense lumen prodution of our sun

just because it looks bright and light dosent mean many/all lumens are reaching the substrate!!!

Anything is awful at projecting lumens out over a distance.  That's the entire basis of the inverse square law.  But while I'm passionate about this hobby and respect everyone here, I really don't think that the field of mushroom cultivation as a whole is really competent enough at this point to be able to draw conclusions about efficacy from common practice.  So much of what we do is just anecdote, intuition and hearsay. 

Oh, and you are supposed to put your lights close to your fruiting chambers.

You definitely don't want HPS, wrong spectrum.  Standard MH bulbs from the hardware store are about 4,200k color.  You can get specialty MH bulbs any where from the standard 4,200k all the way up to 20,000k (the higher ones are typically used in reef aquariums).  The biggest meatiest shrooms I've seen were grown outdoors under sunlight.  The couple of things Ive put outside in flower pots all had dense stems, none of this hollow stuff you get inside.  Not to say that it can't be done indoors, I've seen some beasts here on the forums.  You can grow them in complete darkness, ambient window light, a cfl or even using an big old ballasted grow light.  So I'd say it's a combination of all the things required to grow them:  RH, temperature, food , light and of course genetics plays a role in every thing.  You limit one of those requirements and you limit your potential.

The main reason you have to keep the cfls more than an inch or 2 away from the myc is because of the heating/drying effect the bulbs can cause.  Not so much an issue with plants, but with something as sensitive to RH as myc, it's a huge deal.

The other reason people don't use high wattage lights is the energy consumption and all of the extra stuff that comes with firing up a 400w or higher bulb inside (ventilation etc).  Most grows on here are a couple of SGFC a few monotubs etc, that's a lot of extra energy and detracts from being able to grow mushrooms on the down low.  CFLs/fluorescents just fit most people's needs better.  It's no different than MJ growers using the cfls instead of the big boy lights.  The CFLs may fit their needs and get them by and work, but just working and the best results are 2 different things.

I think it's splitting hairs.
People have had plenty of pins and good growth without getting all science-y about Kelvins and spectrums.

Mushroom can grow in very little lighting. Like this grocery bag I  had full of coir/verm/brown rice. No I left this bag out on the floor because I planned on throwing it away but what happened next amazed me I produced a bigger flush in the bag. This is a picture of how it was growing

It gave me a beautiful unexpected flush.

I have one question about power consumption though currently I have a 7watt cfl 6500k, I'm curious to know know much money it costs to keep it going for 12 hours a day for a month
