House & Garden Soil Nutrient A - 5L

House & Garden Soil Nutrient A 5 L: Mid-Scale A&B Soil Base The 5 L jug of Soil Nutrient A is the mid-size Part A of the House & Garden two-part A&B base. Same chemistry as the 1 L and 20 L versions — primary macros and micros, plus the notable calcium contribution that distinguishes the H&G A-side from competing soil bases. Calcium drives cell wall integrity and active nutrient transport in enriched soil, and the formulation puts meaningful concentration in the bottle rather than treating Ca as a trace element. The two-part split exists because of precipitation chemistry — some elements would crash out if combined with Soil B in a single concentrate. Add Soil A to water first, mix thoroughly, then add Soil B separately. Liquid Soil Nutrient A for Hobby and Small Commercial Soil Rooms What 5 L gets you is the in-between volume hobby growers eventually move to once they've outgrown 1 L bottles but aren't filling 20 L jugs in a season. Pair it with the matching 5 L Soil B for volume-matched mixing across multiple plants. The size suits hobby rooms, small commercial setups, and multi-tent operations running continuous soil programs. The mixing sequence is the same as every other size in the H&G line, and once it becomes second nature the rest of the system is simple. Same rules at every size, same chemistry across the bottles. Key Features Part A of Two-Part Soil System: First half of the House & Garden A&B base. Carries essential macros and micros that pair with Part B. Calcium-Enriched Formula: Notable calcium content supports cell wall integrity and nutrient transport in enriched soil. 5 L for Mid-Scale Soil Grows: Practical volume for hobby and small commercial rooms running continuous soil programs. Macro and Micronutrient Foundation: Core mineral base that prevents nutrient gaps in high-nutrient enriched soils. Hand-Water and Drip Compatible: Liquid concentrate integrates cleanly into manual and automated irrigation setups.
