Just want to add that this needs to be rinsed very very well with regular water before using again as I made this a quick video. I would flush at least 5 times as some plants are sensitive to bleach. I have a few small holes that the perlite cannot go through and use a fine mesh sink screen so that I can easily flush the water but not let any of the perlite down the drain to clog it.
Hello, I am unsure what you refer to with cakes? If referring to mushroom growing, then yes, I would sterilize unless your cakes are 100% colonized and at no risk for contamination.
@plntfriends OK thank you. Yes they are fully colonized and I am currently soaking them in water. Tonight I will roll in vermiculite and place in the tub. Thank you!
