It pairs with Sensi Bloom Part B 500 mL for the matched trial pair. Once the pH Perfect buffering proves itself in the reservoir and the plants show response, growers typically step up to 1 L or 4 L bottles for the next cycle. The 500 mL size is also useful for growers testing Sensi Bloom in a single tent alongside their existing base nutrients before making a full swap.
