mac Posted July 24, 2009 (edited) The T Scopulicola is nice one of my favorite cacti , i could happily roll out my swag & live there Edited July 24, 2009 by mac Share this post Link to post Share on other sites
bℓσωηG Posted July 24, 2009 The T Scopulicola is nice one of my favorite cacti , i could happily roll out my swag & live there Looks like my dream house also, but you wouldnt want to be a sleep walker lol, ouch! Kiwi cacti rock ,my introduction to trichs was in the south island ,at Orepuki .Its amazing how well they grow in the cold ,must be the abundance of volcanic rock you get there ,man i wish i could bring back a truck load of scoria from the beaches in Taranaki. Hang loose bro Share this post Link to post Share on other sites
Μορφέας Posted July 24, 2009 Its amazing how well they grow in the cold , be the abundance of volcanic rock you get there Does volcanic rock make cacti grow better?? How does that work? Do you mean the high geothermal gradient or that the minerals in the volcanic rock allow cacti to grow in the cold better.... wow cool. Share this post Link to post Share on other sites

Do you mean the high geothermal gradient or that the minerals in the volcanic rock allow cacti to grow in the cold better.... wow cool. Well it is very porous providing good drainage a favourite of japanese ariocarpus growers, and well alot of trichs do originate in valleys between and on volcanos in the South American Andes ,im sure the minerals are utilised by them too.. Pumus is good should find that ok in the eastern states on the beach after storms. I use alot of charcoal for added carbon and drainage . Potting mix definitly doesnt cut it my book. There are places where the soil is very warm from geothermal activity,farkin best you know what ive ever sampled taranaki thunder,pu,pu.

Μορφέας Posted July 24, 2009 (edited) very porous volcanic rock? i know sandstone is, breccia is, conglomerate, some volcanic rocks are porous, depends on the deposit though, some would be pretty poorly porous. Thanks for the explanation blownq! hmm volcanic pyroclastics will be the only volcanic rocks with any significant porosity, magmatic deposits of basalt rhyolite andesite granite gabbro ect would have poor porosity, if none at all but that of gas vesicles, lava deposits again, poor porosity except for gas vesicles...

Anyway scoria is very common on the west coast of the north island full of bubbles but does hold some water maybe too much. Share this post Link to post Share on other sites
Μορφέας Posted July 25, 2009 perlite, scoria, pumus are all volcanic pyroclast's, rocks that form from magma being blow out of the vent in the air, they are very porous and permiable. all other volcanics are crap ..lol I know my rocks, alot more then anyone else on this forum I'm willing to bet!
