(left to right) |
Fi-Grow rock wool is produced from molten slag rock and the fiber is granulated immediately after fiberizing. Fi-Grow is totally sterile and inert and is an ideal medium for plant propagation, compost extending and soil conditioning. The rock wool fibers are designed for ideal fiber size, texture, capillarity and structure to enhance plant growth. Fi-Grow is available in its natural state as a water absorbent (WA) granulated form. Three-size grading (Coarse, Medium, Fine) is available to suit the particular application and mixing needs.
