High Humidity? Please Help
    #799355 - 08/06/02 07:43 AM (15 years, 8 months ago)

I've had mixed success with my first batch. First I had 5 PF cakes in 1/2
pint jars in a transparent plastic container. From them I got about 9 grams
of dried goodies. I was hoping for 17.5, but not that bad for a first try,
right? The problem is that I think the humidity was too high. There was
always condensation on the sides of the container, even if I didn't spray.
In fact I didn't spray very much at all. My question is was that bad? I
figure if I can see the water on the side the humidity id pretty dam high,
right? But my stuff seemed pretty much on the small side and there were many
aborts. There were a lot of good ones, but a few seemed very squishy almost
like they were starting to rot. Most of the larger one seemed to have
problems supporting their own weight and when I went to get spores from one
it completely tipped over. I can say I wasn't very careful about
sterilization at that point but I wasn't foolish either. Many of the squishy
ones had a dark center. Any ideas? Contamination?

I had originally made eight jars but only five fit into the container well.
I wasn't too worried about the other three since this was just a test run.
However after the first 5 I tried to see if I could do something with the
rest. Now these jars were old - 3 to 4 months old. And one of them had what
look like contamination even though is was probably just one that grew
smashed up against the jar and got wet. Anyway the other too looked

I broke these up on water saturated perilite that was baked in an oven
covered with foil at 250 F for an hour (then cooled of course). This was set
about a day and a half covered until the mycelium started to grow (wow its
still alive). Then sterilized (pressure cooker 15 psi 25 mins) and cooled
perat moss / vermiculite (1:1) was placed on top of the broken cakes.
Everything looked good - Mycelium growth followed by pinning everywhere. I
was very happy, but that was it. They all look aborted. The largest abort
(1-2 cm) was picked after about a week after I noticed it and was very water
logged, squishy, and dark on the inside.

Now I know these cakes were old, did that have something to do with it? I
know you're supposed to have very high humidity, but could it be too high? I
only say that because they almost seem to be drowning. At first I'd air out
and spay about one daily but a good amount of water pooled under the pan
holding the casing (large drops not completely covered). I didn't spray as
much but continued to air once a day. Condensation was always present on the

Anyway if any of you experienced people have some ideas or comment I would
appreciate it. I'm going to have someone start my second batch and well I
don't want to F it up.


P.S. Also, the light I've been using is mostly indirect natural light. Does
it help to keep the light on 24 hrs.? Direcly above or is indirect okay?

The moisture on the side is condensation... although it might mean you have high humidity, what it actually means is the temperature inside the terrarium is higher then outside of it. Ivest a couple of bucks in a hygrometer so you know for sure and go from there.
