RZ INTRODUCES ROCKWOOL IN OKURA

RZ LDKO CilegonPEKANBARU. Thursday (9/4), RZ urban farming team visited Tebing Tinggi Okura Village, Rumbai Pesisir District, Pekanbaru, to introduce Rockwool to the local society and train them how to use it.

Rockwool is a horticultural growing media made from the natural ingredients Basalt rock and Chalk. These are then melted at 1600° C into lava which is blown into a large spinning chamber, which pulls the lava into fibers like “cotton candy.” If you have ever visited a volcano you have probably seen these fibers flying around in the air surrounding the volcano.

Once the fibers are spun they are then compressed into a mat which is then cut into slabs and cubes. The rockwool granulates are just bales of uncompressed fibers. The process is very efficient, producing 37 cubic foot of wool from 1 cubic foot of rocks.

Since rockwool is born in fire it renders the product chemically and biologically inert and creates the ideal growing medium for hydroponics. Since its development in Denmark in the early 1970’s, rockwool has become the major vegetable and flower production medium throughout Europe and North America.

In this opportunity, there were 18 local residents who participated in this training. “Thank to RZ for the training, it is beneficial and useful for us,” a participant said. ***
