"Volcanic rock" in place of perlite?
    #2887954 - 07/14/04 01:11 AM (13 years, 6 months ago)

    I searched for this one, but didn't see it directly addressed....  I was at the garden store and saw "volcanic rock," one cubic foot in a bag.  It was a bunch of unshaped stones that were reddish in color.  Each one was about an inch and a half by 3/4 of an inch wide.  This isn't geolite, or lava rock.  Volcanic rock. 
    Would this work for a humidifying layer in a fruiting chamber?  I'd just like to avoid perlite as it's kind of messy.  Anyone used this?  Thanks! :grin:

Volcanic rock is lava rock. Lava comes from volcanoes. It should work the same as Geolite, im not sure about replacing it as perlite though. Just make sure to do proper cleaning techniques too make sure it wont contam your grow.

"I celebrate the Earth, my home, my mother, my grave, and as long as men are Man they must, if they would preserve the integrated being, do the same---[and preserve]--this rank casual hungry smelly sweaty lusting transitory body, my oozy pulpy liquid-bag-swollen body, bones, blood, hair glands, my bejeweled sex; I love and celebrate it all.  never to let men forget that they are animals as much as gods---that is one thing I shall say."

It's doubtful that it will have the same desird effect as perlite, even though perlite is technically very small white volcanic rock. Because of it's size and the size of the pours in perlite, it can effectively absorb and then re-emit water through these pours, where-as the larger size of the volcanic (red rock) will not function in quite the same way.

Perlite shouldn't be very difficult to locate. Most garden centers in big-box stores will carry it (Lowe's, Home Depot) and your local garden specialty store and nurseries should probably stock it too as it is a very common soil addative for water retention.
