It's definitely an interesting idea that should be considered. It reminds me of coal plants and how nowadays we can have the proper systems in place that capture all the bad from coal burning while still generating all the electricity (filters, trapping systems, containment protocols). It does seem that obviously open air burning is bad but with the right systems in place this can be a viable option for removing plastic waste. The problem as with most things is having enough money to build the proper facilities. I also think people are just put off by the idea that burning something can actually be beneficial so there does seem to be some closed mindedness when approaching this topic. People feel a little better about themselves by recycling or throwing things away properly rather than just being like "wellllll I lit it on fire". If we all just accepted and researched all ideas instead of treating plastic pollution as a black or white subject, I feel is where the answer truly lies.

It does seem that too high of humidity will lead to increases in bruising. Finer water particles will help as well so yeah as Erik mentioned the Hart system. Bruising is damage to the cells which can be caused if the cell is unable to breath. If the water particles are completely covering sections of cells then they are unable to breathe causing cell damage. I guess it would be awkward with a lions mane fruiting body but any ability to cut the fruit bodies off the block instead of hand twisting and grabbing may also help but i don't know more of a guess. 

Also if you wanna skip that incubation period from culture to spawn, we have all our blue oyster species available as ready to noc grain spawn as well.

Yeah this plays along with idea that Bacteria are smart and always learning as well. If you give bacteria a problem it will eventually figure it out. But if you keep switching the problem Bacteria won't have the time to adapt and learn how to handle the new problem. Or in our case we are preventing the bacteria from learning how to take over our mycelium. A better way of thinking about it might also be bacteria and drug resistance. You keep hitting the same bacteria with the same drug after enough generations some resistant bacteria will appear. You introduce 1 phenotype to bacteria over and over eventually it will adapt and have a generation that works against this 1 phenotype.

I haven't personally seen people grow lions mane on logs but it is an option and I think it gets mentioned in Paul Staments growing guide. For logs in general they tend to take much longer to produce a fruiting body but the fruiting bodies may be a little more full and contain more compounds of interest. This is especially true for Reishi so I don't know how it would apply to lions mane. As Erik mentioned short logs help cut down the time to see fruiting bodies and since it is a dense food source you will probably see multiple fruits. For lions mane bag cultivation is a lot quicker and still produces bountiful fruits with all the desired compounds of interest. Side note, We had someone use lions mane block as compost for their garden and come next year he had fruiting bodies coming out of the ground, which was very cool to see for lions mane.

cooler conditions but everything should still be all good to go. Refrigeration earlier on than hitting the leading edge is probably the more reliable and safer method. Should also make things less stressful and easier to plan without always worrying about the perfect moment to transfer. But then also like I mentioned a few days after hitting edge is no problem at all.

So the leading edge is what gets emphasized as it's the best location from which to obtain mycelium (place of most cell division). That being said even if the mycelium has spread all the way to the edge of the plate it is still viable to be transferred and will grow on grain. We sometimes aren't quick enough to grab the plate at that "perfect" time and will often have to use plates that have hit the wall of the plate. In this case we just take cutting not from the wall of the plate but a little removed like 1cm or so in case of any contamination from the parafilm. Okay back to the question, a few days after hitting the edge of the plate is perfectly fine even without refrigeration. Problems arise once it's been around a week or more at the edge with no refrigeration. Refrigeration at that point will still extend the shelf life of that plate. Refrigeration at the midway point is very viable I would just keep an eye on if the leading edge stays healthy since it would be dividing under
