Some may value the alleged speeding up more than the decrease in yield. In another thread you mentioned people not being concerned with BE, which is true, grain is cheap.

Homebrewers will aerate their wort prior to pitching yeast, the additional oxygen promotes a fast yeast growth, this ensures a vigorous brew to take off quickly. This speeds up the brew time, and decreases the potential for contams to take hold. Oxygen is then restricted since you do not want the sugars used up making new yeast rather than alcohol.

This could work in a similar way, speed up colonisation so contams have less chance to take hold. You sacrifice some of your substrate to get this.

If something reduced the maturation time of sclerotia to 50%, but lowered the yield to 50% then many might do it.

BTW My grow area is usually only 16C, so I do incubate
http://en.wikipedia.org/wiki/Room_temperature
Most here tend to be growing in bedrooms, where 18C (64F) is the  "recommended room temp".
If you want air circulating in a colder room then you could put the jars on electronic devices in standby mode, like dvd players

I'm curious to see the results of further testing of this possible variable. I would try it, but not until I see more results for myself.

Here's an interesting bit of information. I have some petri dishes with Ps. cubensis Orissa strain culture on them. Half are plain MEA agar, the other half H2O2 MEA agar. The ones with the H2O2 are all doing far better than the ones without. This in my experience is quite unusual, the H2O2 usually slows the growth of mycelium markedly but I'm having very different results with this particular strain.

Do you mean h2o2 in your actual MEA or in the TIT with the MEA?

H2O2 in the actual MEA. Different to what you're talking about, I know, but still relevant.

Yeah I'm not too sure really, it's quite strange. Usually I've had the polar opposite effects as mycelium really doesn't like H2O2.

If you added it to hot agar it may have degraded quickly turning to oxygen and not having much of a disinfectant/slowing effect.

Yep, you got me there! Most say mature sclerotia is stronger though, maybe sclerotia is not the best example. But do you see my point? say your cube grow of 1 kilo of dry grain gave a fresh yield of 1 kilo over 6 weeks. If you could get 1/2 kilo in 3 weeks many might prefer it. People could be in a rush, going away on holidays etc. Many will toss grows that could get another small flush from, not being worth their while.

Just figured I'd chime in here... I had 3 jars that were just *not* colonizing fully... They smelled fine, and showed no signs of bacterial contamination... They wouldn't colonize the bottom even after I flipped them upside down.

I added 100ml of H2o2 into the bottom of a small Tupperware container (about 1cm up the jars), and put them in it, and closed the lid...

Came back 3 days later to find that one had fully colonized... And two hadn't moved at all.

Unforuntately, one of the ones that hadn't fully colonized yet pinned invitro (I'd assume from the burst of oxygen and lower temperature due to evaporation of the H2o2 that was covering the bottom of the glass jars.

Not sure what this means, and I didn't bother to read the entire thread, but I figured I'd relay my results.

Nope, that certainly didn't happen. I added it when it was cool enough to handle. I also knocked up a few other dishes with another species and had the polar opposite effect. This culture hates the H2O2 but is growing fine on the agar without, so it definitely has not degraded.

Of course it would have pinned lol but my silly theory is that if you do it from the start the myc gets use to it or whatnot.

what percentage was your h2o2?

Tripsis exactly what amount of H2O2 did you add the the petri dish with the Orissa?

1ml of 3% H2O2 to 150ml of agar. It sounds strange I know, but the Orissa culture seems to love it yet the other species I have going wouldn't touch it and I had to transfer them last night.

prehaps a better idea is your orissa isolation is just more aggresive.

h2o2 attacks living cells.
