Inorganic material experience......Magic blocks?
I´ll have to surf the net about those leca products.......
I have this idea of wanting to grow my orchids freely, mainly on a stub of wood, but I have recently stumbled across a material called magicblocks, which is supposed to work well with orchids planted on these blocks. Has anyone heard about this before. (Sorry, a little off topic) Thanks. Victoria "Ray @ First Rays Orchids" skrev i en meddelelse ... Ah yes. Thanks. Basically, some of the rock wool has water-repellent coating. It still holds water via capillary action between the fibers, but not nearly as much as the regular hydrophilic fibers. I believe the perlite is added to make it more airy. My own experience is with LECA products, but I have used some rock wool in the past. For me, it has some of the same negative attributes of sphagnum (too easily packed, making it too soppy), but cannot decompose. -- Ray Barkalow First Rays Orchids http://www.firstrays.com Secure Online Ordering & Lots of Free Info!

Diana It contains a small amount of beads of perlite and mostly of something like rockwool, but in shredded small balls. It is supposed to both contain and expel moisture. Victoria |
