Hello everyone. I m using silica fume in my plants. Seems to work perfectly. Effects noted after 1 aplication at 1×1000 concentration. Internodal lenght diminished considerably and 100% resistance to powdery mildew. I m aplying to the soil and foliar in veg.
Has anyone tried using silica fume as a silica source? I guess this is an industrial sub product. Could this be harmful to human health?
Silica dust is extremely harmful to human lungs. Be very careful with it. Only use it in well ventilated areas with a mask. It can cause cancer and other breathing problems.
