Why X Nutrients Bloom FX Comes in Three Bulk Sizes Volume is the only thing separating these three containers from each other. The formula is identical in all of them: a concentrated liquid phosphorus and potassium supplement guaranteed at 0.3-0.8-2, with nitrogen present only in trace. Where the sizes differ is the scale of operation they suit, and the difference is larger than it looks on the shelf. One gallon mixes about 252 gallons of finished solution at the label rate of 15 mL per gallon. The 2.5 stretches to roughly 630, and the largest container reaches about 1,261. Shipping weight climbs with it, from 10 lb on the smallest to 50 lb on the biggest. All three go into soil, coco, soilless blends and recirculating reservoirs with no change in method. The base is inorganic rather than organic, and the line carries no OMRI listing. That rules it out of certified organic production, which is the first thing to check before any of this is worth reading. Picking a Bud Enhancer Size Against Your Tank Volume Work backwards from the reservoir, not from the price. A room mixing a hundred gallons a week through an eight-week flower will move most of a single gallon in one cycle. That makes the smallest container the honest starting size for a one-room grower. Step up only when two or three rooms draw from the same stock. A concentrate sitting open for eighteen months does nobody any favours. The largest container earns its place where a dosing pump and a bulk tank already exist. Decanting something that heavy is routine there rather than a two-person job. Mixing rules do not change with volume. It goes into the reservoir on its own, never premixed with another concentrate, and pH gets set once everything else is already in. The ramp schedule is the same as well, climbing five millilitres a gallon each week of bloom. Track EC or PPM as that number rises. The trade-off with bulk is commitment. These sizes only pay off once the feed programme is settled and the line is not about to change.
