Last Saturday I went out in search of "coco fiber" I hear you all talk about. I found this one product "cocao mulch" which was the husks from cocao nuts. Smelled absolutely delicious like chocolate. The husks act as a ground covering. NOT. I finally found this stuff in the pic at the indoor grow shop for $4 for a 1.2 lb. brick. The bowl in the pic is from about 3 tablespoons, hydrated, of the dry fiber. Is this it?coco fiber

ok this is 5 pf cakes cased in coir. pinned in natural day light. the harvest was 109 shrooms. the mushrooms were also rather large. the casing depth was 1". took about 10days to colonize the casing layer and walla. low and behold a ton of shrooms. i love this coir stuff. very simple and easy. i suggest it to beginners who have problems with casings. 1

how are those flat cakes cased with coco fiber, could you give some detailed instructions on how it was done?

Eatyou, for future reference, what works better.. Usuing coco fiber to case with, or shit?

do you think that pinning in natural Sunlight makes a difference as opposed to artificial light

By Nan (Nanook) on Friday, November 02, 2001 - 12:17 am:

My questions are...

1) Do you Sterilize the coir?
2) Do you buffer the coir with Lime?
3) How is the Trich in the later flushes?

By Lichen (Lichen) on Friday, November 02, 2001 - 12:30 am:

to respond to plink's query, I'd say that the light makes no difference, whether sun or artificial light. Not with non-clorophyll plants. They are photosensitive, but they do not need direct light.

There is a major difference between shrooms grown in a terrerium on cakes and shrooms grown on dung or other substrates outdoors. They are short, and have large caps when grown outdoors. Indoors they get tall, with slender stems, but the caps usually stay small, only an inch or two in diameter. But sometimes they grow larger than that, depending on what tek you use. Like that one shroom Nan grew whose cap dwarfed a 1/2-pint jar...or the shroom we saw posted here growing in a gallon milk jug...these are huge, but not specifically because of whatever kind of light they were exposed to.

skunkyherb, I am not certain if I can agree with you on the herb, because I have never grown in artificial light. I always grow using sun and some one-toke shit this year, but I don't even know where I got the seeds, and I think the genetics have a lot to do with it.

1. Tim Leary, the casing is just a regular casing with coir on top and bottom. no flat cake.

2. Unkyherb, I have had great flushes with dung and lime, and peat and all others. but coco is the easiest i have tried aside from 50/50. no sterilization necessary. and in personal opinion the flushes are better on coir. but this has to do with many factors such as growing conditions, lighting moisture, temp and ect. [See P. Cubensis Growth Parameters]

3. Plinker, i have a vitalight which is the suggested light in the mushroom cultivator. it does well with pins but my results are so much better with natural light and have always been. i would suggest nature.


a) i do not sterilize the coir when first bought. maybe if i have opened the 15lb brick a few times then i will microwave it for about 2 mins or so

b)i do not use lime or oyster as a buffer. i may try it but i don't think it is necessary if this worked well. so i will probably do what is easier and works. which excludes using lime. i may do an experiment with lime or oyster shell next time to see if there is a difference.

c) you know nan, i am not too sure about the trich in later flushes bc that is my first coir flush besides one other tray and it is still taking a while to colonize the reapplied coir for the 2nd flush. but i will keep you posted on future flushes. that is a damn good flush for the first try wouldn't you say. that is why i am suggesting the coir to all. easy!!!!!!!!!!!!!!!!!!!!

By Nuecrew (Nuecrew) on Friday, November 02, 2001 - 02:19 am:

I have asked this once before. What is COIR? And what is the word "trich" as Nan used it? And Eatya, is it possible for a schematic or wordy description of your humidifier setup with the pvc pipe. I have asked for that info at least three times. (I know you don't owe it to me but I'm just dieing to know). Is it possible to keep a bookshelf size grown closet humid without a humidifier?

By Mrt (Mrt) on Friday, November 02, 2001 - 06:01 am:

Nice fruits!! T.C.'s are my fav. A bit slow, but its well worth the wait.

coir is coconut husk fiber.
trich is a nasty Green Mold.
and you could humidify a small closet by hand misting, without Humidifier.

By Swilly (Swilly) on Friday, November 02, 2001 - 05:47 pm:

nice ones brother man i cant wait to get my hands on some t.c.'s also what was your regular caseing you mentioned that you used?

By SYDYSTYK (Addict) on Thursday, November 08, 2001 - 11:34 am:

this question is directed to anyone who has an answer, say eatu took his beautiful plexi custom (or a terrarium of that size, actually a little smaller) and left all his casings/flatcakes inside but tried to grow with a couple christmas light size lights(all other parameters left the same), what would it do to his amazing yeilds?

shrooms aren't photosynthetic, they do not use light to fuel their growth.
so, assuming your proposed lights are bright enough to trigger fruiting,
then yield should not otherwise be affected.

By Nozza (Nozz) on Thursday, November 08, 2001 - 04:24 pm:

I suspect I do get bigger flushes when I use a fluoro when initiating pinning. Likely?

By Mrt (Mrt) on Monday, October 29, 2001 - 02:01 pm:

This might sound like a stupid question, but here goes.....when using coco fiber as a casing layer do you cut off an inch thick slab and put it on top of your colonized substrate or should you crumble it up? I have some in the mail but I've never even seen the stuff.

By Swilly (Swilly) on Monday, October 29, 2001 - 05:28 pm:

crumble it up

By Brettiejams (Brettiejams) on Monday, October 29, 2001 - 05:34 pm:

yes.. you want the casing layer to be uniform all the way across.... crumbling is the best way to get the stuff to a uniform size that is easy to work with.

Thanx guys!

Here are some treasure coast. 5brf cakes cased in coco fiber. pinned in dual chamber terrarium and fruiting in entrainments system.1

UUUh...I know you guys said that coco fiber is just a casing and shouldnt allow for spawning, but..

I finally found some and took some cakes out of the dunker and recased using only cocofiber. This was done 4 days ago, today I checked on the spread and it sure looks like its working through the fiber. Maybe not spawning but alot better results than I thought..This stuff is very cool.

Another positive recommendation!


the cakes were, however, originally grain spawned to compost before the first flush and dunk.

my batch of 'rye-spawned' coco fiber also seems to be progressing well.
now to get some pinning started...

By Joe Mamma (Madscientist) on Friday, January 11, 2002 - 03:09 am:

I cased up three trays off coco. Works well. ai have a few pins inside of a five days.

By kobayashi (Impalerzz) on Sunday, January 13, 2002 - 08:01 pm:

I am casing with cocofiber, and the spread looks good and even so were into pinning..

My Q: Myc is peeking thru, so should I add more coco over the top? Maybe getting more even pinsets, and less pin abhorts(my biggest problem to date)?

Should I just allow it to colonize the whole top layer, and if so do I risk overlay(75f, 90%)?

Thanks you all, I am eliminating my mistakes one by one.

you don't want everything covered, just the tiny valleys between the high spots, roughly 20-30% of the total.

By kobayashi (Impalerzz) on Monday, January 14, 2002 - 04:58 pm:

So should I add some more moist fiber to the top of the casing during pinning/fruiting?


By quote: (Quote) on Monday, January 14, 2002 - 11:49 pm:

no, not during pinning/fruiting.
you only sometimes patch the first spot it breaks thru, to give the rest time to catch up.
but once it breaks thru again, let it be.

By kobayashi (Impalerzz) on Thursday, January 17, 2002 - 07:57 pm:

Any reccomendations on the amount of misting cocofiber casing should be getting prior to first flush?

They seem ok, although my grandma says the fiber on top is a tad dry, and its pulled away from the sides a bit..

that's something you'll have to develop an eye for as you gain experience. just go low, a little at a time, that's easier to fix than too much.

By kobayashi (Impalerzz) on Saturday, January 19, 2002 - 06:21 am:

do you think "low" is just a fine mist once a day??

yup, one or two squirts.
