Beating Green Mold

Howdy all, just for the record I am not a chemist and cannot corroborate with any of the evidence submitted previously for or against the use of bleach in growing mushrooms. I can however show you my results. After my first flush I noticed green mold starting to invade my cakes that were nearly spent. This presented me with the perfect opportunity for a trial run of the notorious Bleach Dunk!

This is a picture of my cake after its first flush. It really wasn't that green, I just got scared and hosed the whole terrarium with hydrogen peroxide turning most of the little aborts green


This is a picture of the cake just after I put the 1% bleach solution in.



This is the cake after 12 hours of sitting in the fridge.



Here is our little friend again after being re-double end cased and placed back in his home.



All of these cakes were dunked using bleach at the same time. The pins are forming after only three days.



Going crazy two days later, I forgot to take a pic before I started plucking so the ones on the chicken wire are from the cake at top right.



Finally the next day I am happy to say that nearly 100g wet came from only three cakes on their second flush. Add about fifty to that because many weren?t ready by the time I left for work this morning.



If I start to die of dioxin poisoning I?ll post a note on the board. The cakes only smelled of bleach for less than a day. I was also able to clean out my terrarium in the process and I am happy to say that I see no more signs of green mold. (Adam Sandler voice) "Hydrogen peroxide is good!! It kills the germs and makes the shrooms happy and good!! Bleach is better!! It kills everything in it's path and leaves the mycelium shiny and new!! Oh really fool!? REALLY!!"

How can a bleach dunk at that concentration be harmful?

"Under normal household use, sodium hypochlorite is broken down in the environment into table salt, oxygen and water. Other substances may be formed, to a small extent. These by-products are most often referred to as AOX (adsorbable organic halides). A great many studies have been made to provide a risk assessment of household bleach in terms of its formation of AOX.

The conclusions drawn were:

the amount of AOX is very small both in absolute terms and relative to other human activities and natural sources,
the majority of these AOX are easily degradable,
the AOXs formed are primarily water soluble and not bio-accumulative.
highly chlorinated species, such as dioxins, are NOT formed. "

I work in the food service industry and we dissinfect everything with bleach which is highly recommended by most if not all of the health boards in north america.
Also a mixture of bleach/vinegar/water is used for the sterilization of fresh produce to kill micro-organisms

"The important factors affecting the germicidal properties of chlorine include the acidity (pH) of the solution, the concentration of the chlorine in the solution and the temperature of the solution. The most economical and readily available form of chlorine is bleach. Bleach is a solution of sodium hypochlorite (NaOCI) in water. Most common laundry bleach is 5.25 percent sodium hypochlorite in water. Sodium hypochlorite solutions are very alkaline with a pH in excess of 9 or 10. At this high pH, bleach is not a very effective germicide. The pH of the bleach solution must be reduced to between 6 and 7 in order to form hypochlorous acid (HOCI). Hypochlorous acid is the most germicidal form of chlorine in aqueous media. Thus, when bleach is added to water to form a germicidal sanitizing solution it is necessary to adjust its pH to between 6 and 7. The easiest and most economical way to do this is to add distilled vinegar to the bleach-water mixture. When enough vinegar is added to adjust the pH of the solution to between 4 and 5, the solution is mostly hypochlorous acid (HOCI), and its germicidal power is greatest. However, when the solution pH is between 4 and 5 it is very corrosive to metals. Thus, using the bleach solution at a pH between 6 and 7 gives satisfactory germicidal power and the solution is not excessively corrosive. When the pH of a bleach solution is decreased to below 4.0, deadly chlorine gas is formed. Thus, it is important to only reduce the pH of the bleach solution to not less than about 6."

Next time you try the dunk Hippie try adding vinegar to get the proper Ph level and see if it makes a difference.

I find that this tek is cool and all. 1% bleach in water probably isint very harmful, especially when its used just to grow shrooms.

However, bleach has been known for its envoirnmental hazards. I never use bleach anymore because once it goes down the drain it'll probably end up int he ocean. Its extremely detrimental to our envoirnment. It usually will kill anything in its way at full concentration, but at 1%, it doesnt seem like such an issue?!

lol
you have got to be kidding me.
what 'experts' at forestfloor ?
some wannabe pseudo-experts flamed me when i posted it,
but they aren't experts by any means,
and posted irrelevant nonsense..
you want to talk about dangerous,
prove it.
they could not.
i bet you can't either.
don't let ignorance be your guide,
think for yourself.
this tek works, and is perfectly safe.

hey, thanks for the great info.
i've searched all over but did not find such clear instructions on ph's role in the germicidal effectiveness of bleach, i'll add some vinegar to my next series of experiments, and pass the word.
thx, again.

nice flush & pic.
i don't think bleach dipping is going to be very useful on casings, more useful on cakes.
surprised though that you beat the mold, usually it burrows underground and comes back.
check out this link, everyone, for more great info on bleach dipping.

Nice Job, Hippie...

So that is a Pint jar you got that dunking in, right?..

Q: approximately how much bleach is 1% in a pint jar?..

Thanks!..

use 1 cc bleach per 100 cc water.
also, adding 2 cc vinegar per 1 cc of bleach will improve germicidal properties.

Other than the inherant problems with this idea listed on FF, there is also the problem that their are a number of different types of green molds, penicillium, cladosporium, aspergillus and trichoderma being only the most common - each of which being able to tolerate different levels of toxins introduced into their environment.

lol
and bleach kills each and every one on your list. and most others as well. it's one of the most effective disinfectants around, and very safe around humans.
if you did some research you'd discover that even NASA used bleach to sterilize space craft so they won't accidently contam other planets.
the grocery store uses it to clean your produce,
bakers use it to make flour white,
which they put in our bread, etc.

and the bleach at those levels you have prescribed kills all those molds including endospores, yet does not cause mutation of the mycelia or cause the fruits and mycelia to build up toxins? Only cubensis mycelia would be able to grow in that kind of toxic substrate and i could not see it having positive effects on its growth
At best it could be a short term solution, like antibiotics in agar media. Repeated use of antibiotics results in mutations... Personally i thinks its far safer just to improve your technique so that you dont have contaminants in the first place.

well, you're certainly entitled to your opinion.
but that's all it is-
just your opinion.
you offer no evidence on any issue,
just lectures on what you think everyone else should do.
but i seriously doubt if everyone will heed your call
to just do more cleaning,.
