House & Garden Soil Nutrient A 20 L: Production-Scale A&B Base
The 20 L jug of Soil Nutrient A is the production-scale Part A of the House & Garden two-part A&B base for enriched soil. Same chemistry as the 1 L and 5 L versions — primary macros and micros plus the significant calcium contribution that supports cell wall structure, active nutrient transport, and structural integrity through the full crop cycle. Calcium is one of the elements that most lower-tier soil bases shortchange, and H&G builds it into the A-side at meaningful concentration. The two-part split exists because some of the elements in Soil A would precipitate if combined with Soil B in a single bottle. The mixing rule is the same at every size: add A to water first, mix thoroughly, then add B.
Large-Volume Soil Nutrient A for Continuous Production Programs
What 20 L gets you is reduced restocking frequency for production rooms running multiple zones or greenhouses on continuous feeding schedules. Same feed quality across the full container. It mixes cleanly in both drip irrigation and hand-watering, runs without residue, and pairs with the matching 20 L Soil B for volume-matched mixing across rooms. This is the size for facilities that have already validated H&G on smaller bottles and want bulk volume without committing to a full drum. Ignoring the A-then-B mixing rule at 20 L scale is more expensive than at hobby scale because the precipitate goes everywhere.
Key Features
- Part A of Soil A&B System: Carries the primary macros and micros that pair with Soil B for a complete two-part base in enriched soil.
- High Calcium Content: Supports robust cell wall structure, nutrient transport efficiency, and consistent mineral delivery through the crop cycle.
- 20 L for Large-Scale Operations: Bulk format for commercial rooms, multi-zone greenhouses, and continuous high-volume soil programs.
- Complete Mineral Foundation: Delivers the core macros and micros that prevent nutrient gaps in enriched soil environments.
- Drip and Manual Watering Compatible: Mixes cleanly into solution for both automated drip and hand-watered environments.
