AN pH Perfect Sensi Grow Part A (500 mL): Trial-Size Hydroponic Veg Base
Sensi Grow Part A at 500 mL is the trial size of the calcium-nitrogen side of AN's pH Perfect Sensi Grow two-part veg base. Part A carries calcium, iron, and the nitrogen that drives leaf expansion and chlorophyll production during veg. Calcium sits on the A side because it can't share a bottle with phosphorus in storage — that separation is standard across every serious two-part base. pH Perfect Technology auto-buffers the reservoir to 5.5–6.3, which at the trial scale matters because a new grower evaluating the Sensi program wants to see the buffering work before stepping up jug size.
Pairs with Part B 500 mL for the Complete Trial Kit
The 500 mL size is the testing-scale entry point. Pair it with Sensi Grow Part B 500 mL at 1:1 for the complete two-part veg base over a short trial cycle. Once the grower has seen pH Perfect buffering hold the reservoir through veg, they typically step up to 1 L or 4 L for the next cycle. Sensi Grow Part A is also available in 1 L, 4 L, 10 L, 23 L, 208 L, and 1000 L — the full ladder runs from trial scale up to commercial barrel and tote for large multi-room facilities.
