ZeroTol HC vs. ZeroTol 2.0

ZeroTol HC is formulated for home and hobby growers - same PAA chemistry as ZeroTol 2.0, sized and labeled for smaller-scale growing operations. For commercial CEA and greenhouse operations managing disease pressure across multiple plants or rooms, ZeroTol 2.0 is available in 2.5, 30, and 55 gallon.

Because ZeroTol HC leaves no residues and has a 0-day PHI, it pairs cleanly with biological applications - use it to knock down existing pathogen populations first, then follow with biological inoculants or beneficials that would otherwise be disrupted by residual chemistry.
