During the incubation period of a PF cake does exposure to light become important immediately upon innoculation, or is the light only needed after 100% colonization of the cake? When does the light need to be introduced? |

Light stimulates pinning... nothing more.
Remember, the entire colonization process in a nuatural setting would happen under the ground. |

So with that rationale, do the jars need indirect light during the incubation phase as the pf tek says they do? |

Like I said.. the light is a stimulus.. for pinning.
If you were to colonize in complete darkness, and then introduce light, you'd still get pinning... It'd just take a bit longer.
In fact, if you introduce light too early.... you can get pinning before 100% colonization. [which is fine for invitro growers]
Best to begin exposure to light at about 75% colonization IMO.
Keep in mind..... there is no concrete do or die way to grow our shroomy friends.
As long as the basic requirements are met, there are a miriad of options to "tinker" with.... all , of course, falling within the basic criterium for sustaining a fruiting colony of mycelium. |

Direct sunlight is TOO INTENSE and not at all recomended.... Filtered or indirect sunlight can be O.K.
Plain flourescent tubes are probably the safest bet... They provide adequate light without giving off much heat |

I have a question about lighting its fall/winter now here in minnesota so I was wondering can I just give my cakes caseings whatever this light because It's not so intense as summer light? thier might be an advantage to winter now  can I leave them in the light all day now? because I don't know how fake light could be just as benifecial as mother natures light is thier really any diffrence? |

I am planning on using an O3 Actinic blue fluorescent I read somewhere to encourage pinning you want a light in 440 Nanometer range and mostly blue spectrum These bulbs are almost entirely in the blue spectrum and reach 440 to 470 nanometers they are used for Saltwater reef tanks.
Just a thought its convient for me I have a reef tank the bulbs are relatively expensive about 19 bux for 24 inch bulb
[ed. note: a few months later it was determined that these lights caused harmful mutations in the strains grown under it.] |

Here is the deal... shrooms are phototropic... they only use light as a stimulus. The stimulus (in this case) tells the fungus that it is above ground and it's time to fruit (spread the seeds (spores).
Plants... on the other hand, photosynthesize... meaning they convert the light to energy.
The mycellium(mushroom fungus) draws no energy from the light.... so the type of light you use makes little difference... and since we are growing shrooms in a controlled enviornment... the ability to produce the needed light to provide for the fruiting stimulus without the addition of heat (thus avoiding the drying influence and raising of temperature caused by heat) is in most cases beneficial.
For all intensive purposes... flourescent tubes of any type (the cheaper the better),since they are cooler than regular incadescent bulbs, are your best/safest bet for an indoor light source for shrooms.... but pretty much any light source is adequate to provide for the phototropic stimulus needed by the fungus to fruit. |

People I know use Sylvania Gro-Lux fluorescent tubes. Their light output (color temperature) is heavily biased towards the blue end of the spectrum, i.e., they are a very "cool" bulb. As noted above by Delta55 and Stamets (The Mushroom Cultivator), these short wavelengths encourage pinning. Sylvania Gro-Lux have been around for a long time and are used by people I know. Was also thinking of getting one of those Actinic bulbs from Top Bulb. Quite frankly though, most any old light seems to work... |

is light even really necessary at any point in the growing process? before you reply what a moron i am, think about it. fungi grow in the dark all the time. my college biology instructor said that since fungi do not go through photosynthesis like plants, obviously they should not require light. my instructor contends that fungi grow BEST in dark warm places. has anyone tried the entire process in the dark? results? |

While the fungus itself indeed prefers warm dark places.... shrooms are indeed phototropic.
That means the fungus draws no energy from the light(like plants with photosynthesis) but they do use the light as a stimulus.
The light stimulus tells the fungus that it is indeed above ground and it is time to fruit.
The fungus also is stimulated to fruit by a lowering of temperature, and a lowering of C02.
All three of these factors provide the stimulus to fruit..... you may be able to get some fruiting without the light stimulus... but it would hardly be under ideal conditions and I would question as to whether the flush would be very good.
Go ahead and try..... I'll stick to what I know though |

Hi, do the tap lights that run entirely on batteries provide any heat? If not, what would be the best way to provide heat and light for invitros without any cords (i.e. battery powered)? Thanks! |
Nan (Nanook)

Not much heat from a tap light. Beware they are going to require a set of batteries every day if you use them a lot, the expense quickly adds up.
Battery powered heat/light is going to be expensive unless you use a set of commercial grade rechargable batteries, keeping one set in the charger while the other set is doing duty.
I have never seen Teks posted on this topic. You are on your own as far as the R & D is concerned. If you come up with something that works, please post about it. |

Try an electric lamp. A small florescent light will provide light as well as some warmth from the bulb and ballast transformer. I have seen some in auto parts stores that have the ballast on the plug, the bulb is sealed in a water and shock resistant plastic tube with rubber stoppers in the ends. They do not get hot, but are warm to the touch.
Marx2k's Fruiting Chamber uses both a florescent bulb and a fish tank heater, yet the electrical load is small enough the whole thing will run off the lightest weight extension cord. |

hey ya'll- I've done this before actually- most novice electricians can do it- I wired 6 tap lights to a ac adapter... just bridge the lights, attach + to + and -to- to the adapter- I think it was a 9 volt(whatever the sum of 6 needed).
AH- the old lost art of soldering. |

I was talking to a guy at a bird shop this weekend. (I love cockatiels). Anywho, he said to get the closest to actual sunlight you have to go with the flouresent rather than tunsten filiment lights. There are some tunsten bulbs that claim to be close to sunlight, good for the dark winter months etc. |

Hey guys, thanks for all the info on temperature. Some of you suggested I try out Hippie's invitro tek, and I've been thinking about it. Whenever I decide to start I think I'm going to do about 10/12 jars, with half using hippie neglect, and half double end cased in a perlite terrarium (per nan's recomendation). I'm still a little concerned about temperature. But I think I'm premature in my worries. I won't be starting until January, and who knows what my room is going to feel like then. May be colder, or may have the heat on 24/7 and be 75-80*. I'll just have to wait and see.
Anyway, If I'm using 1/2 pints to make my cakes, is there going to be enough room in the jars for invitro tek to produce shrooms? I think I've heard of transplanting to pint jars or something after invitro pinning, but I can't remember.
Either tek is going to require some light. Which I can't pull off easily because, A. I don't want shit sitting out in my room. and B. I don't want to run extension cords into my closets or cabinants (looks a little suspicious)... So.. I was thinking about buying a few of those lame "Touchlight" things. I believe they're battery operated and you just push them to turn on and off. It would probably be a very soft light, but if my terrarium used plastic wrap, I think it might be enough. Anyone have any thoughts on this, or some other idea. Remember that I would really rather not run electricity into my closets, battery power is perfered.
Thanks guys

You'll get yourself some babies with Invitro, and as for Light, although some folks do different, you really only need a couple hours a day when pinning and fruiting, if even that much. |

Hippie's neglect tek [Growing Invitro] was, I believe, an idea concieved for use with low proflie 1/2 pint jars; at any rate, it works quite well. The fruit conforms to the inside of the jar. You'll be surprised how much room there is in there.
As to your lighting problem, maybe battery power is the right choice. Get something with rechargeable batteries, get a couple sets of Ni-Cad batteries, and it should work. Maybe one of those nifty handheld flourescents that fold, or some such |

Ok, so if I put the terrarium/jars out in the open for a few hours a day (indirect sunlight + flouresent light in the room).. that should be enough? Maybe give some battery powered light at night, or is that more or less optional. Thanks guys.

If i were you id just let em chill in their jars and everyday take them outa the dark for 1-2hours, not even... Just put em out when no ones around or you are in your room to see whos goin in and outa it... thats what Id recommend, batteries are expensive. If you have closet doors set up the jars so you just have to open the closet and light hits the jars... ive heard of ppl getting pins with 20mins of light per day... |

you can get pins just by leaving them on the computer desk. long as there is a light and you can see the jars you will get pinning. when i had my first rubbermaid i just broke a lamp around the house and duct taped it onto the lid. it wasnt a fire hazard because it was a flo and wasnt to much wattage. a glowing rubbermaid looks odd LOL. you can also get a rubbermaid and cut around the sides and then put plastic on top of the lid and just give it light threw the plastic. or you can get clear 'maids. your choice, hope this helped. |

Yea, I was thinking batteries would either get expensive or time consuming (having to rotate rechargeables) if I had to leave them on most of the time. And if they don't need constant light, why not just sit them in the open for a few hours. I can swing that, I just don't want to have my set up in the open all the time. Thanks.

jared (Jared112)
| | Posted on Tuesday, December 04, 2001 - 05:38 pm: |

Any kind of lighting (white light) will work. Scientific studies show that it only takes 1/1000th of a second strobe flash to induce pinning. That is all the light is for is to make the mycelium start shooting pins. that and the mushrooms will grow towards the light, so I'd say an hour a day from something even as dim as a taplight:
Would be sufficient enough. |

what if you had jars out for 1.5wks in indirect light, and then put them somewhere with almost no light, will they fruit invitro? they were getting fuzzy/bumpy before their disappearance from the world of light. |
jared (Jared112)
| | Posted on Tuesday, December 04, 2001 - 09:22 pm: |
|
You could do that, but It don't really matter how long you expose them to light, it matters how often you expose them to light. For an example mycelium needs light to pin right? well if you expose them to light for a few days, and put them in a pitch black fruiting chamber, they will grow and fruit. However there will no longer be any pins growing. You should expose them to light at least once a day. Basically its God's way, the mycelium grows underground in most cases or wherever there is no light. Then it knows when to fruit when it gets hit by light, its kind of like saying "Ohh I can see light, I must be breaking through the surface, time to fruit some mushrooms"
That's the way I see it anyway. |

they can fruit in the dark, once light has triggered pinning to begin already.
but the yield is much better if you can just give them a few minutes of light daily.
for invitro aka hippie's mycro tek aka neglect tek where you fruit in the jars, expose to light from germination on. |
