AN pH Perfect Sensi Bloom Part A (500 mL): Trial-Size Hydroponic Bloom Base
The 500 mL trial size of Sensi Bloom Part A is built for growers who want to test pH Perfect technology before committing to full-season jugs. The A side of the pH Perfect Sensi Bloom two-part base carries calcium, iron, and a portion of the nitrogen — the cations and mobile elements that have to stay separated from phosphorus in concentrate. pH Perfect chemistry self-buffers reservoir pH to 5.5–6.3 without manual adjustment, which is the feature most growers want to see in action before they scale up. One 500 mL bottle runs a small tent through one veg-to-early-bloom cycle when paired with Part B at 1:1.
Starter Size Before Stepping Up to 1 L, 4 L, or 10 L Bottles
This size is specifically the trial entry for a new grower or a veteran switching over from a different bloom base. 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. Dose at 1:1 with Part B through the flowering phase.
