Casing opinions?
    #6652877 - 03/09/07 01:09 PM (17 years, 24 days ago)

Opinions on my casing? Half the shrooms are growing dildos out of their heads, something can't be right.

Did you happen to use Lysol or any other petroleum product at or around your FC?

Nope, only thing that's been near the FC is Surgical Spirits. At one stage the casing was misted with 3% h2o2, nobody seems to be able to make up their minds if that's right or not. It's not too dry is it? How do you even tell if it's too dry?

Did you mist with straight h2o2 from the bottle, or did you mix it with water...either way using h2o2 on your casing is really not a good idea. By the time you put on a casing layer you should take the proper precautions to not have contams and shouldnt have to consider h2o2 necessary or wanted.

Also, how are you getting FAE in there?

The h2o2 came in a bottle that read "30 volume" which I assume means 30% so I diluted it 10:1 with water.

Fresh air is via regular fanning and it's a very large container with just a tiny casing in it.

hrm
my math says: 30% diluted by 10 is 3%, which is the strength of peroxide that most pharmacies carry, which is what ppl say dilute by 1:10, so you really want .3% peroxide solution.

did your casing fizz at all when you sprayed it?

Hmmm... I bought it from a pharmacy in South Africa. The bottles only read 10, 20, 30 and 40 Volume. No mention of an actual percentage anywhere. There certainly was no fizz or anything like that when I sprayed.

interesting...
no fizz is good

and just the bases are swelled, with tiny heads right?
im guessing too much humidity, causing water logging

and as rygo said, hows that thing being aired out, and how often?

edit: and how often are you misting as well?

I wouldnt imagine any bottle of h202 comes from pharmacy at 30%, so that prolly means 3%.

Haven't misted since pinning started. Fan it about 3-6 times a day. Didn't realise you could have to much humidity with perlite?

I guess the bases are a bit swelled and the heads a bit small relative to my last grow of Equadors (these are cambodians) which was done in the same FC but with wet sponges instead of perlite.

I've got little flaps at the top of the FC with a couple of air holes underneath, should I just leave these open all the time?

yep, leave em open
perlite manages to release an ass load of humidity
casings require about 92-95% humidity, you probably have 98-99% humidity at almost all times (except for when you fan)

btw, roger uses perlite, but he also drills hundreds of holes in his box to make sure theres enough air. no standing water in the perlite, just damp perlite, and he says in spite of the holes, perlite is pumping out 95%+.

btw, nice mutant on that casing. stamets had a picture that looks just like that mutation in one of his books.

I never put casings in tubs that are that much considerably bigger than the casing itself. Casings put off their own humidity when kept in a reasonably sized tub, thus no need of any perlite.

Otherwise you gotta start using the whole Cool Mist/Ultra Sonic stuff.

I might be mistaken, but I think I read that this can be caused by inadequate air exchange, or by humidity levels that are too high or fluctuate too much.

Many thanks guys!

So once I've got the humidity lowered should the problem with the water logging correct itself, i.e. will the shrooms reach maturation?

30 volume hydrogen peroxide is 10%, so you'll want to dilute it roughly 3 to 1 with water to reach the 3% level for killing off contaminants. It's incorrect that you want to dilute the 3% any more. 3% is the strength to spray on Dactylium(cobweb) for example.

I disagree with lowering humidity. Mushroom primordia form best in near 100% humidity with plenty of fresh air. This means you want fresh air and moving air, coupled with high humidity. If the casing layer is saturated, it means you've over misted, or possibly made it too wet to begin with, but high humidity will not get your casing layer wet, but rather will only slow down the evaporation of moisture from it.

Mutants such as you show in the first picture are genetic in nature and not caused by anything you did, or didn't do. If you clone one of those fruits, your entire next project will look like that. Personally, I think they're cool and have several isolated mutant strains that are fun to grow once in a while. Here's one of them below. Good luck to you.

Hey RR

This doesn't seem to be the case.

I had six casings like the pictures above: All of them were BRF cakes spawned to coffee/coir, cased in verm/coir and misted with an h2o2 solution. They all had exactly the same mutants and no single mushroom reached maturity.

As a control I cased one BRF cake directly with verm/coir, no misting, no bulk substrate. It's growing perfectly healthy mushrooms (will post picture soon), no mutants, which should read maturation any day now.

All of my cakes were inoculated with the same spore syringe. Surely this means that the mutations I had were in fact caused by something I did?
