my mycelium turns blue/green all the time
    #7408031 - 09/14/07 07:46 AM (16 years, 4 months ago)

it has been the second time now, that the mycelium of my preprepared cubensis ban hua thai cake (from magicmushrooms.org) turns green/blue
i keep it in a "2-storey" terrarium with water at the bottom (there's a heating staff in the water (turned to 24° Celsius))
the cake sits on the lattice in the middle
i have grown shrooms in that terrarium many times before and only got that blue/green mold thing once (that was because there was too much sunlight shining on it, which is definitely not the case now)
i sprayed the first of the kit, whose mycelium turned blue/green subsequently with casual tap water (i thought, that this was the reason), so the second time i sprayed with cooked and then cooled water (i've done that many times before, it always worked well)
after 3 days, the mycelium turned green/blue again
i always washed the terrarium thouroughly before putting in the cake and before that, i even washed it inbetween flushes
i'm not sure, if the blue/green stuff is mold or something else
the place where i keep it is pretty dark all the time, but not too dark, so there is some light there, as i said, previous kits growing there never faced that problem
what could be the reason?
i don't want my next kit to get the same problem
thx in advance

Not to say I'm an expert but I've read enough here to get an idea of possible problems...

First off, contams CAN grow in absolute dark but incubating with "some" light present likely aids their invasion. Stick to total darkness IMHO. It also sounds like you might be winging it a bit with your washing techniques. Granted, that alone may not be the sole cause but if it indicates your general way of handling your grows, you might want to look over your adherance to which ever tek(s) you are using. There may be some gaps in the processes you are letting happen. Just my .02c.



EDIT: Also, I've seen some valid arguements against having any standing water in your terrarium/FC. I saw a pic of someone using a similar set up and they had a glass of water just sitting in the tank near the cakes (to add humidity). People resoundingly called out that they should take it out. It makes sense to me that having standing water all by itself might be a nice breeding ground for contams in general. Enough so that even nicely colonized cakes would be under siege as a result. I'd assume having a 2 story set up with standing water below the cake rack would also lead to these problems. Maybe I'm wrong though and one of the REAL experts here can correct my assumptions.

my advice...
1.) learn how to grow mushrooms without a kit....
2.) perfect sterile technique
3.) stop using heat it makes a better enviroment for contams.
4.) use moistened perlite at the bottom of your terrarium not water
5.) make sure humidity stays above 90% and provide plenty of fresh air exchange


to be perfectly honest i didn't understand half of what you explained, but to me it sounds like your method needs a lot of improvement, i've never gotten a contam because of too much light. you shouldn't have to wash your terrarium between flushes either a colonized cake is fairly contam resistant. perhaps you could show some pics of your setup, because i cant picture what you're talking about with a two story terraium with water in the bottom with a heat wand, but it sounds like a perfect enviroment to grow contams in, and not so ideal for mushrooms, i could just be misunderstanding you though.

This is a problem. Find perlite... Warm water is like a resort for nasty shit to grow in.

since i don't have a digicam, i drew a picture of the growbox in paint (it looks retarded, but you should get the picture):

http://www.file-upload.net/view-408017/growbox.JPG.html

the black thing in the water (which is blue :wink:) is the heating staff, the red stuff is the heat
i put it there, because it gives the right temperature (24°Celsius) and contributes to the right humidity
anything wrong with that setup?
it has worked well many times before, but it could be totally wrong
i'm not at all a professional grower, nor am i a wealthy man, so i can't invest money in different methods to maintain temperature and humidity

it sounds to me like your problem is humidity, not contams, but i may be wrong. standing water with a heating element will give off far less humidity than damp perlite (which is what you need to buy)
you should brush up on beginner techniques, because i've never ever ever seen anything with standing water in a fruiting chamber...that's just bad practice my friend

Get rid of standing water. If you can't find perlite, you can use paper or cloth towels in the terrarium. Replace paper towels or wash cloth ones every three days to prevent molds and/or bacteria from growing on them.

I've ran terrariums with a large bath towel soaked, then well rung out and folded loosely, then laid into the bottom of the tub. Humidity stays as high as several inches of perlite. People with humidity problems in mini-greenhouses can also hang a damp bath towel or two inside the greenhouse for a great boost.

whenever I "spray" the cakes, I get contams. every time.

recently, there was a mist that just stuck to a cake, and after a few days the water turned to a golden gel, and i swear a few of the gel-droplets started to grow like mushrooms. I was waiting to see what happened, however I checked one morning and saw about 3 different colors, so I chucked it.

I have learned to spray the inside walls of the chamber (be it a terrarium, or plastic bin), and sometimes I pour some water into the bins, so that the bottom layer of perlite soaks it up a little, and there isn't any standing.

after my last kit has been contaminated by the bluegreen mold again, i decided to stop doing the "heater rod in standing water"-tek
i want to try it with some perlite next
so, my questions are
can i use the heater rod without water?
it looks like this:
http://www.elektroniktreff.de/aetzen/heizung.jpg
if you turn it on and touch it, it's preetty hot,
so hot you immediately stop touching it
i'm worrying, that it will either damagage the terrarium,
the perlite or the cake
where should i put the perlite?
should i leave it in a plastic bag?
or should i put a perlite layer on the ground of the terrarium
here is the pic of the growbox again:

You shouldn't need the heating rod at all. You should be fine fruiting at room temperature.

well, i'm not sure about that
room temperature in my case is 18-21° Celsius
at night, i open my window, cause i need fresh, cool air for sleeping
temperatures sink even further at night
so, you guess, i can be fruiting at an average of 18°Celsius?

No problem. Don't heat terrariums. Cubensis will fruit indoors easily from 15C to 30C. Allow the temp to rise during the day, and fall at night for best results.

ok, thx for the answers
i will give it another try without the heating rod
should i simply put the perlite at the bottom of the terrarium?
should i soak it in water before?
how much should i use?

Take the perlite and soak it in water for awhile, then drain it well.

It works BETTER that way than any standing water. Simply resoak it when it dries out, but always drain it well.

EDIT : a 3" layer is what I'd use.

so 2 more questions:
where do i get perlite, if i don't want to order it on the web?
what kind of shops should i head for? headshops?
are there also other kinds of ordinary shops, who sell it?

and, if i want to do PF-tek, do i NEED a pressure cooker?
don't the jars break in the pressure cooker
should i put water in the pressure cooker?
if i should not put water in the pressure cooker, doesn't that damage either the jars or the bottom of the pressure cooker?

Holy shit man... You need to search around a bit and read up...

1. Perlite is for gardening... Search places that sell gardning stuff.

2. A pressure cooker is VERY helpful, but people seem to do without. I'm not sure how, since I have one. And no, when used properly they obviously don't break the jars. And yes, you NEED water in there or else it burns up and ruins everything.

Keep reading and using the search posts function. :goodluck:
