AN pH Perfect Sensi Bloom A & B (4 L Set): Home Grow Hydroponic Bloom Base
The Sensi Bloom 4-liter A & B set is the working size for a single-tent or small-room grower running pH Perfect Sensi Bloom through a flower cycle. Part A supplies calcium, iron, and a portion of the nitrogen. Part B supplies phosphorus, potassium, and the chelated micros that can't share a bottle with calcium. The pH Perfect chemistry inside both jugs holds reservoir pH inside the 5.5–6.3 sweet spot without manual buffering, which is the feature that makes Sensi a good fit for growers who don't want to live with a pH meter in hand. At 4 L each, a single grow gets you through roughly a full flower cycle in a 4x4 tent with room to spare on dosing flexibility.
Step-Up Size from the 1 L Starter, Pairs 1:1 for the Complete Base
The 4 L set fills the gap between the 1 L starter pair and the 10 L production size. Home growers running Sensi Bloom for the first time typically step in at 1 L, get a feel for the feed chart, then move to 4 L for the next cycle when they know the program works. Dose 1:1 for the baseline bloom feed. Sensi Bloom integrates with the full AN additive lineup — Voodoo Juice, B-52, Big Bud, Overdrive — so the 4 L base sits at the center of a program you can build out as the grow matures.
