  • SI is essential to the leaf and stem strength and allowing the plant to hold up heavier fruits.
  • This fertilizer is intended as a supplement to a regular fertilization program.
  • Studies have shown that when used in cloning and seedlings silicates help speed up the growth by as much as 80-90%.


Ensure your plants are getting all the nutrients they need, with Structural Integrity from Humboldt, a rich source of potassium silicate that will promote a range of important biochemical processes. Soil is often deficient in many of the nutrients plant's require for optimal growth, inlcuding silicate. Silicate is used by plants for all sorts of things, such as increasing stem strength and improving structural intregrity –  there's a reason why Humboldt calls this product Structural Integrity! When plants are physically stronger,  this means tha are able to climb higher towards sunlight and might succumb to all sorts of nasty diseases. Structural Inegrity can be used in hydroponic systems, as a foliar spray or as a general application, improving growth by up to 80-90%!
