      I only use food grade rye as well. It has made a profound difference in lowering contamination rates. It's ironic that you're making these videos, because I almost simultaneously switch to brown rice as. I'm finding there's not a lot of information on prep. If you'd like to share your process, I'm all ears!

      @@Loader138 video coming up one of these days, but very simple. For regular brown rice: boil water fully, then add grains and simmer on low-medium heat for 9 mins. Then rinse thoroughly with cold water, and then strain vigorously to get rid of as much excess moisture as possible. Once no water is falling off the colander after a vigorous shake, then I will load into jars and sterilize in my instant pot for 2 hours.

    From my research and experience endospores can survive heat only when they are in the dormant stage and heat is a great catalyst for waking them apparently soaking in heated water for a few hours allowing them to cool for a few more then drying and pc or pc twice first time for one hour then again for two hr. or something like that. This gives the endospores time to wake up so they are vulnerable. Or you could just source grains that don’t have as many endospores. I hope that helps.

    • @Mycophilia
      @Mycophilia  Рік тому

      Yes, sounds like you’re trying to describe a process called tyndallization, and it was used more commonly in the past before PCs were fully adopted. Again, my grains were fine. Until a moth infestation; they were not bought as dirty grains.

    Great video! A few question how do you store your cultures? because the other day i tried reviving some cubes from agar slants kept in the fridge around one year old and it was just dead(good thing i had some spores prints), but all my other gourmet mushrooms(oyster,enoki,lionsmane,chestnut,etc) are perfectly fine, can cubes not handle the cold?
    Also what is your thought on the senescence of cube mycelium, can i keep growing from the same agar culture or do i have to go back to spores? i have had non conclusive results in my experiments, gourmet varieties seem to do fine with with endless growing of the same mycelium.

    • @Mycophilia
      @Mycophilia  Рік тому +1

      That’s strange, they can last many years stored in slants but your fridge may have simply been too cold for them as they are a tropical species.

      Senescence is real, and depends mainly on how you store the cultures and how often you expand them. The better they’re stored, the less senescence. A culture can last for a long time if they are treated properly.

    Just lost two full tubs to Trich overnight. Very frustrating. One day it was fine, the next it was all green. I am sure you have already tried this Sage but because I am trying to be hyper aware of contamination I would pasteurize my Coir to hydrate and then add to a bag and sterilize in the PC then add to the sterilized tub with a casing layer. STILL getting contamination on some tubs but I have to think that it HAS to be coming from ME or the environment. I don't have too many areas in my house that I can use as a clean room so I have to improvise. Such is life. I just keep trying and watching your channel for the good tips.

    @dack4545 Рік тому +1

    Liquid culture is way faster than agar and just the same amount of contamination chance ,when you think about the process. 👍

    • @Mycophilia
      @Mycophilia  Рік тому +2

      Yes faster when it’s already made properly, but contamination rate is much higher in getting to the clean culture. It is an added step to agar, so by that virtue alone it brings more risk and time, plus the liquid makes it hard to spot various types of contamination compared to the 2d outline of an agar plate.
      The faster colonization really hinges on whether you will be growing lots of any single culture, aka you are growing commercially. Most hobbyists are not constantly growing the same culture, which really would be the only time the speed of LC really means anything.
      Additionally, you have to wait for the LC to colonize, and then test it on agar. So unless you’re growing commercially, and the initial time investment is worth it to you (because you intend to grow lots of it), it takes a lot longer, and brings greater risk than simply growing out agar and inoculating with it. As you see in this video, full colonization in 8 days. That is completely fine by me lol

    Hi.
    I'm just starting out so I've been watching tutorial vids almost non stop..
    One thing I've noticed is everyone talks about contamination and how it's bad etc. But I havent seen anyone explain what happens if you haven't spotted a contaminated batch and put it to bulk.
    What happens next? Do they still fruit and if so, will the mushrooms be ok to eat or will they make you sick? Or will there be obvious signs if they have managed to grow?
    It would be great to see a short vid explaining the cons of not spotting contamination and why it's so bad.
    Sorry if this seems obvious but as i said, I'm new to this and keen to learn all i can.

      I probably wouldn't have eaten anything that didn't look or smell right as I'm quite fussy but it's good to know that some risk can go beyond having fruiting bodies..
      I'm taking great care at every stage and your tutorials have been a great help.
      I decided at the beginning to wrestle with agar plates and although it's taken me a few attempts in refining my process I'm glad I did because I never realised just how interesting and amazing it is to observe the cycle of growth. I think I'm hooked..
