Olet oikeassa, optimaalinen lämpötila on itseasiassa hieman korkeampi. HuMy:ssä viitataan lähinnä siihen, että normaaleissa huonelämpötiloissa (usein 22-23 astetta) on kolonisoitumisen nopeus jo sitä luokkaa ettei erityistoimille ole tarvetta. Itse olen pitänyt huoneen lämpötilassa ja suuretkin, jopa 5 litran kokoiset pussit, kolonisoituvat melko nopeasti, usein 2-3 viikossa. En siis ainakaan omien kokemusteni perusteella näe tarpeelliseksi tehdä erillistä hauotomoa. Sellaisen rakentamalla voi säästää aikaa, mutta kokonaisuudessa ei puhuttane mainattavasta erosta. Panostaisin ennemmin esimerkiksi kannan eristämiseen ja nesteviljemien tekemiseen, jos haluaa säästää aikaa ja saada parempia tuloksia. Täytyy kirjoittaa asiasta tarkemmin seuraavaan versioon oppaasta.
Shroomery RogerRabbitilla on asiasta myös suhteellisen vahva mielipide:
"And I've been trying to correct that disinformation for years. It's all based on a chart somebody mailed to stamets many years ago showing 86F to be the peak temperature for growth of cubensis on a petri dish, and everybody just accepts it as though Moses carried it down from the mountain on a tablet of stone. However, every single experiment I did to try to duplicate that with extremely accurate temperature monitoring was unable to verify that bogus 86F figure. What I have repeatedly found regardless of strain is that cubensis colonization remains rather flat from about 75F through 81F. Beginning at 83F, the rate of growth falls off sharply. By 86F, growth has slowed down nearly 50% what it was between 75f and 81F. These experiments were conducted on petri dishes that produce little to no heat because of the very thin layer of mycelium. In jars, up to several degrees of heat is produced by the colonizing mycelium; so definitely don't go over 80F to 81F if you're looking for maximum rate of growth. Furthermore, bacteria and thermophilic molds such as Mucor, the black pin mold are stimulated by higher temperatures. Therefore using an incubator set to 86F is certainly favoring bacteria and molds, while slowing down mushroom mycelium growth. Below is a picture of one of my colonization shelves. It sits in my bedroom at normal room temperature and quart jars of rye berries colonize fully in ten days, and pf jars colonize fully in 14 to 21 days, but usually closer to 14. How often do we see posts where people have incubators set at 86F, and they're asking why their jars aren't colonized after four to five weeks, and they have large spots of yellow liquid forming? The liquid is metabolites that the mycelium secretes in response to stress, usually from competitor molds and/or bacteria. What has happened, is they've slowed down the mycelium while stimulating the competitors."
