CHB Premium 21

Premium 21 is an organic certified, soil applied, highly compatible liquid humic product. Bio-Gro’s product technology allows the humic acid colloid to be mixed with other liquid fertilizers and remain evenly dispersed without compromising colloidal structure, unlike standard humic products in which colloids agglomerate into large particles, with reduced surface area.

Premium 21 reaches the roots, where it’s needed.
