House & Garden Soil A – 5 Liter

House & Garden Soil A is Part A of a two-part base nutrient concentrate designed for plants growing in soil and enriched growing media. It delivers balanced macro and micronutrition — including a significant quantity of calcium — and is always used together with Soil B to provide a complete nutrient profile across all growth stages.

Why Choose House & Garden Soil A

House & Garden Soil A is the first half of a balanced two-part base nutrient system built specifically for soil and enriched growing media. The two-part format keeps chemically incompatible nutrient compounds separated in concentrated form, which extends shelf life and maintains stability until the moment of mixing.

The formula contains every essential macro and micronutrient required for healthy plant development, and is notably high in calcium — an element that plays a structural role in cell wall integrity and is commonly deficient in heavy-feeding crops. By pairing Soil A with Soil B, growers deliver a complete and balanced feed in a single reservoir fill without the need for supplemental calcium additives under normal feeding schedules.

• Two-part system keeps concentrated nutrients stable and chemically separate until dilution
• Contains every essential macro and micronutrient for all growth stages
• Significant calcium content supports cell wall development and reduces deficiency risk
• Formulated specifically for soil and enriched media — not a repurposed hydro formula
• 5-liter bottle offers a practical volume for small to mid-size grow operations without the bulk of larger sizes

Best Uses for House & Garden Soil A

Soil A is designed for growers working with soil or pre-amended growing media who want a clean, complete base nutrient without relying on multiple separate bottles for primary nutrition.

• Vegetative and bloom feeding programs in soil-based grow systems
• Enriched potting mixes where a base nutrient is still needed after the initial charge period
• Gardens where calcium delivery through irrigation is preferred over foliar application
• Growers transitioning from a single-part nutrient to a more complete two-part system
• Commercial and hobbyist soil grows where nutrient consistency and batch-to-batch reliability matter

If you are also running a root-development program, products like Advanced Nutrients Tarantula or Earth Juice Hi-Brix Molasses can be used alongside a two-part base nutrient like Soil A & B to support beneficial microbial activity in the root zone.

Compatibility

House & Garden Soil A is compatible with all soil and enriched growing media formulations. It is not intended for hydroponic or coco coir systems — House & Garden produces separate Hydro and Coco A&B lines for those substrates.

Always use Soil A together with Soil B. Neither part alone provides a complete nutrient profile. Mix each part separately into your reservoir water before combining to avoid precipitation.

Soil A is generally compatible with most organic additives and supplements used in soil programs, including molasses-based carbohydrate supplements and microbial inoculants. When adding multiple products to a reservoir, add Soil A and Soil B first, then pH-adjust, then add supplements. Check pH and EC after each addition.

House & Garden Soil A is available in multiple sizes (1 L, 5 L, 10 L, 20 L, 200 L, and 1000 L), so growers can scale their purchase to operation size. The 5-liter size is well-suited for home growers and small commercial rooms running up to a few dozen plants per cycle.
