Since you can use 100% coco coir as a substrate....
Does that mean one could theoretically spawn a colonized grain jar
to to a tub of un-pasturized coir?
I guess there's only one way to find out ;)

Also make sure any coir you leave laying around is completely dry, as I've had damp stuff in a container go green before

pasturizing their coir casings."
I agree. foaf stopped pasturizing and just started using it off the brick and didn't get any contam problems.
"are there any threads of people using 100% coir for substrate. if so what is the colonization speed on it?"
Well, I don't have pics but foaf usually spawns coir casings with brf cakes using 3 - 1/2 cakes and 1 pint of coir. (already moist and expanded) Spawn was mixed with the coir very well and compacted down. Allowed colonization for 4 days before adding casing layer (verm/coir) and exposing to fruiting conditions. Nice pinsets followed 10 days later. Worked great, each of those casings produced about 18g-21g dry from the first flush and kept going for 3 or 4 good flushes. (dunks in between)
EDIT: Also, foaf ran out of verm once and did the Double End Case tek with coir on some BRF cakes and got great results.

and the nicest I've come across is Atami Bcuzz Coco.
It's available at hydroponic shops worldwide.
The quatlity is top notch, and it's not compressed like most coco.
"From the beaches of Sri Lanka and other tropical islands, Atami produces coco peat.
Coconut shells are cut and cleaned, then steamed and buffered. Coco substrate is light and stable.
Atami coco substrates are internationally certified by RHP. Available in 50L bags"

Its commonly used as substrate in amphibian terrariums because of its moisture holding ability. Its kept very moist and comes in contact with lots of froggy fecal matter and still doesn't start to grow mold very easily.

I have used coir for the first time to case and I am a bit worried about the moisture that I have in my casing right now. I cased the crumbled cakes about a week ago and the growth is popping up on the suface at about 50-60% coverage.
Now, the coir is much drier looking than when I cased it....this is evident by the color. It is not as dark now. When I take a pinch off of the top where it is not colonized it does not feel wet....but when I put it on my lips, I can feel that it is damp. This is the way I automatically went to do it as my lips are more sensitive than my hands. How moist should they be right now? I have the casings in a growhouse with the humidity at 90-98%.
I am bugging out since I think I should have misted these casing earlier in the process, but now since the mycelium is popping up on the suface, I stand the chance of doing damage to them if I spray.....this is my logic anyway.
What is my play here?

Also I'd recommend keeping your lips off the casing. Mouth's are pretty dirty as far as bacteria is concerned, although we do all reallllly love our mycellium. :D

I think this may too much right now. Who would have known...a digital timer with 30 minute minimums. I think I may need another. Guage says 98% on a polytherm after 30 min cycle, down to 95% right before it kicks in. If I am correct, I should get this at 90% after primordia start, right?
btw, I didn't put my mouth _on_ the casing......I pinched a bit of loose coir from the top of the casing and tested _it_.

If I can just get over that stunt....even if there will be a stunt of growth, I think making it more moist will be adventageous in the long run. Am I on the right page? I done screwed up already, by not keeping them up on max moisture....coir _does_ indeed dry out fast
Btw, is there any quantitative way to tell me how moist these should be right now?
Posted 16 October 2005 - 09:46 AM
i'd just dribble/inject water gently as/where needed instead of misting

you should have already gotten moisture levels in
the casing up before.
if your casing is drying out too fast,
you may need a thicker layer, or higher humidity, etc.
but you can/should mist before pinset, as needed.

It's best use imo, is as a filler material in a balanced compost mix. Mycelium can easily colonize it, and coir holds a ton of moisture. However, its cost makes that use prohibitive.
i have a local place that will sell it to me for $.50 a brick....and will cut me a deal at 50 bricks to $.30 a brick.
