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.

Thanks. This is great info.

Very helpful, thank you.

I just bought a bag of espoma organic perlite. Do i need to sterilize that prior to placing my cakes in the tub?

Is there an alternative to bleach cause my mom can’t touch bleach
