House & Garden Soil B 5 L: Mid-Scale A&B Base for Enriched Soil
The 5 L jug of Soil B is the mid-size Part B of the House & Garden two-part A&B base. The chemistry is identical to the 1 L and 20 L versions: macros, micros, and a meaningful calcium contribution that defines the B-side of the H&G two-part. Calcium drives cell wall integrity and active nutrient transport in enriched soil through the full crop cycle. The two-part split exists because some of these elements would precipitate if you combined them with Soil A in a single concentrate, so H&G separates them and asks you to add A to water first, then B. The 5 L size lands between hobby and production volume — too much for a single tent, not enough for a commercial room.
Liquid Soil Nutrient B for Hobby and Small Commercial Soil Programs
What you get in the room with the H&G Soil A&B pair is steady mineral availability across veg and bloom, no compounding deficiencies in nutrient-dense mixes, and clean reservoir chemistry once you follow the A-then-B mixing sequence. The 5 L bottle is the right pick for hobby growers running multiple plants, small commercial setups, and multi-tent operations that have outgrown 1 L bottles but aren't filling 20 L jugs in a season. Pair it with the matching 5 L Soil A for volume-matched mixing. The line works for both hand-watering and drip systems without residue or clogging.
Key Features
- Part B of Two-Part Soil System: Completes the H&G A&B base pair with the secondary and trace nutrients needed for full-spectrum soil from veg through bloom.
- Calcium-Rich Formula: Significant calcium content supports cell wall integrity, nutrient transport, and structural development in enriched soil.
- 5 L for Mid-Scale Grows: Practical size for hobby rooms and small commercial operations between 1 L and 20 L volume.
- Macro and Micronutrient Delivery: Supplies the secondary and trace elements that prevent compounding deficiencies in high-nutrient soils.
- Drip and Hand-Water Compatible: Liquid concentrate mixes cleanly without residue in both hand-watered pots and drip irrigation.
