Peppers set more fruit and ripen with stronger flavor when potassium stays high through the season, while herbs respond to moderate, even feeding that builds oil content without forcing weak growth.

Every product works in soil, containers, and hydroponic systems, is CDFA registered, and is third-party tested for heavy metals at our FDA-registered Madera, California facility.
