Believe me ive checked many gardening stores lol
Only thing i can get is the white stones they use at outdoor made from limestone. Limestone rocks i believe they are called. Does that work? (dont thing so cause it will turn the pH down a lot)
Kmakok Reviewed by Kmakok on . 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
