House & Garden Soil B 20 L: Production-Scale A&B Base for Enriched Soil
The 20 L jug of Soil B is the production-scale Part B of the House & Garden two-part A&B base for enriched soil and amended growing mixes. Same chemistry as the smaller bottles. The B-side carries macros, micros, and the significant calcium contribution that distinguishes it from Soil A — calcium drives cell wall development, nutrient transport, and structural integrity in enriched soil systems through the full crop cycle. The two-part split exists because some of these elements would precipitate if combined with Soil A in a single concentrate. Pair Soil B with Soil A by adding A to water first, mixing thoroughly, then adding B. The mixing rule doesn't change at scale, and ignoring it at production volume is more expensive than at hobby scale.
Bulk Liquid Soil Nutrient for Multi-Room and Commercial Grows
What 20 L gets you is reduced restocking frequency for production rooms and large greenhouses where you'd otherwise be filling reservoirs across multiple zones from smaller jugs every other week. Same feed quality across the full container, because every gallon comes from the same batch. It mixes cleanly in both drip irrigation and hand-watering, runs without residue, and pairs with the matching 20 L Soil A for volume-matched mixing across rooms. This is the size for facilities that have validated H&G on smaller bottles and want bulk volume without committing to a full drum.
Key Features
- Part B of Soil A&B System: Completes the two-part nutrient pair with the macros and micros needed for full-spectrum soil nutrition alongside Soil A.
- High Calcium Content: Supports robust cell wall development, nutrient transport, and structural integrity in enriched soil mixes.
- 20 L for Production Scale: Large-format volume cuts restocking frequency for commercial facilities and multi-room grows.
- Complete Micro and Macro Profile: Secondary and trace elements that prevent compounding deficiencies in high-nutrient soils.
- Drip and Hand-Water Compatible: Liquid concentrate mixes cleanly without residue in drip irrigation or hand-watering.
