What are the characteristics of vermiculite on flowers?
The chemical formula of vermiculite is (Mg, Ca) 0.7 (Mg, Fe, Al), 6.0[(Al, Si), 8.0] (OH4.8H2O). Monoclinic system, usually in flakes. Brown, brown or tan. Grease gloss. Hardness 1~1.5. Density 2.4~2.7g/cm3, vermiculite calcined at 800~1000 DEG C, the volume of rapid expansion, increasing 6~15 times, high up to 30 times. The average density of vermiculite after expansion is 100~200Kg/m3, because the vermiculite which has been roasted and expanded has fine air barrier, so it has good insulation performance.
No, vermiculite can keep warm and moisturize, but vermiculite doesn't have the nutrients needed by plants, so you need to add fertilizer occasionally
