Depends on what you grow in. Soil, not so much, as Si is available from the soil and most good synthetics contain some anyway.
Now in hydro, that can be a good idea.
Silica will help strengthen cell walls, helps resist insect infestations and helps control P uptake.
Thank you! I grow in promix. I did use it in my cloning and had incredible results. It's simular to hydro.
Would promix along with nutes be enough that I won't need this?
yeah
Thank you! I'll keep it for my cloning and away from my soil.
