I used the bigger ones in the bottom of my pot for extra drainage. Worked fine, but you got to be able to find some perlite somewhere. Go to a God Damn gardening store, anywhere and they will have it.

Volcanic Rock After my first grow that finished in a 5th week whole plant chop....:( im starting to get energies for the next try! :cool: Im trying to get perlite or vermiculite but the people that sell rocks are mentally-retarded where i live. Nobody knows shit about the rock names...they just sell *white rocks* or *red rocks*. Stupid... ANYWAYS! This is what i can get to place in the soil mix. Do you think this little 7mm red volcanic rock can substitute perlite or vermiculite? Volcanic red rock | Rating: 5
