LECA ROCKS(Geolite) suggestions...
    #4269929 - 06/08/05 12:10 AM (13 years, 13 days ago)

Question: In my PMP I have the standard GEOLITE and I have heard various things about contams. I know for a fact that if you dont change out the water for say 2 or 3 months, you get mold from experience. But The rocks themselves are baked at 1200 degrees celcius. I know they're pourous and some aerobes could be lurking in there but then again, aren't fully colonized cakes pretty resistant anyhoo? So Basically, to autoclave or not to autoclave the geolite...that is the question. I would normally just say give em the clave! It can't hurt anything. But My grow system is already set up and ready to go and I am about to be the mother ahem' / father of many..specifically 3 x 1/2 pinters of Alien's substrate cakes (will be used for casing) and 6 x 1 pinters of Alien's substrate ( Will also be used for casing), 4 BRF 1/2 pint cakes and 6 x 1 pint brf cakes ( Will be used for casings). So my QUESTION!!!!! could i get by with not sterilizing the geolite this time and simply adding some H2O2 to the PMP every now and then, or will that h202 get evaporated and hurt my mycelium when I go to hopefully pin and then hopefully fruit?

Personally, I'd clean it out, with alcohol..

Take out rocks, put in a bucket or something, add a bit of alcohol n water....maybe bleach?...Not sure if bleach is a great way to go...

Rinse....then maybe Bake it in the oven for a bit...

That's just me being Meticilious though :cool:

h202 in small concentrations (5% or less) shouldn't harm anything.
