Why do mica blocks the passage of auxin and allow moisture to pass through?
Mica by phengite, quartz, garnet and Jin Hongshi etc., can appear albite, zoisite and chlorite, garnet rich Fe and Mg, phengite in Si up to 3.369, is also high.
Anyway, remember to block the passage of auxin and allow water to pass through. The control variable allows the variable to be single, verifying the effect of auxin on plant growth
