House & Garden Soil A – 1 Liter

House & Garden Soil A is Part A of the two-part Soil A&B base nutrient system, formulated specifically for use in enriched soil growing media. It delivers balanced nutrition across all essential plant nutrients and is particularly notable for its significant calcium contribution, which helps maintain cell wall integrity and supports vigorous vegetative development.

Why Choose House & Garden Soil A

House & Garden Soil A is designed for growers who use enriched soil mixes and want a base nutrient that accounts for what the soil already provides. Here is what separates it from generic all-purpose feeds:

• Formulated for enriched soils: Unlike general-purpose nutrients mixed for inert substrates, Soil A is calibrated for soils that already carry background fertility. This reduces the risk of over-feeding nitrogen or phosphorus into a medium that already contains them.
• Balanced across all essential nutrients: The formulation covers all macro and micronutrients required for plant growth, so you are not relying on the soil alone to fill gaps in the nutrient profile.
• Significant calcium content: Calcium is often under-supplied in liquid base nutrients but is critical for cell wall formation, tip burn prevention, and overall plant structure. House & Garden builds a meaningful calcium load directly into Soil A rather than requiring a separate cal-mag supplement in most standard-dose programs.
• Two-part system chemistry: Keeping Part A and Part B separate in concentrate form preserves nutrient stability — compounds that would react and precipitate if combined at high concentration remain shelf-stable until diluted in your reservoir or watering can.
• Available in multiple sizes: The 1-liter format suits small operations, home gardens, and growers who want to trial the system before committing to larger containers.

Best Uses for House & Garden Soil A

This product is best suited to the following growing contexts. If your setup falls outside these scenarios, review the Compatibility section below before purchasing.

• Potting-mix gardens with pre-amended soil: Soils blended with compost, worm castings, or slow-release fertilizers benefit from a nutrient solution dialed back on background minerals. Soil A&B was built with this scenario in mind.
• Vegetative and bloom phases in soil containers: The balanced nutrient profile supports plants across the full growth cycle when paired with the companion Soil B. No separate veg-stage and bloom-stage formulas are required.
• Indoor container growing: Growers running pots under artificial lighting who want a consistent, measurable nutrient input alongside an organic-enriched substrate.
• Transitional feeding programs: Growers moving from an amended-only approach who want to introduce liquid nutrients without overhauling their existing soil setup.
• Growers managing calcium deficiency: Because Soil A carries a significant calcium load, it is a practical choice in environments where calcium deficiency (tip burn, blossom end rot) has been a recurring problem under previous nutrient programs.

For root-zone development programs, a product like Advanced Nutrients Tarantula can complement a Soil A&B base feed by adding beneficial microbes to the rhizosphere. For a molasses-based supplemental carbohydrate source, Earth Juice Hi-Brix Molasses is compatible with most soil-based programs.

Compatibility

House & Garden Soil A is intended for use in enriched soil growing media. It is Part A of a two-part system and must always be used alongside House & Garden Soil B to deliver a complete nutrient profile. Do not use Soil A as a standalone nutrient — Part B supplies complementary mineral ratios that together create a balanced feed solution.

Growing medium compatibility: Enriched potting soils, amended garden soils, peat- and coco-amended mixes that carry background fertility. It is not formulated as a standalone product for inert media such as rockwool, perlite, or hydroton, where House & Garden’s dedicated hydroponic or coco base nutrients would be more appropriate.

Supplement compatibility: As a mineral base nutrient, Soil A&B is generally compatible with House & Garden’s additive range (such as Roots Excelurator, Top Booster, and Shooting Powder) as well as third-party biological additives. Always add Part A and Part B separately to the reservoir rather than mixing concentrates together, and add each component to water before adjusting pH.

Water compatibility: Suitable for use with municipal tap water and reverse-osmosis water. When using RO water, ensure your base EC is accounted for, as the low mineral starting point of RO water may require you to use the Soil A&B at the upper end of the recommended dose range to hit target EC levels.

Dosing Guidelines

Always follow the dosing chart published by House & Garden on their official website or included with the product. The notes below are general guidance derived from the product’s category and formulation type — not a substitute for the manufacturer’s feed schedule.

• Shake before use: Liquid concentrate nutrients can settle during storage. Invert and shake the bottle several times before measuring.
• Use equal parts A and B: In a two-part system, Part A and Part B are almost always dosed at the same rate. Measure identical volumes of each into your water.
• Add to water, not water to concentrate: Pour concentrate into your water volume (not the reverse) to avoid precipitation in the measuring cup.
• Add Part A first, then Part B: Mix thoroughly between additions. Do not premix A and B in their concentrated forms.
• Check EC and pH after mixing: Target EC and pH ranges for soil growing typically fall between 5.8–6.5 pH and 1.2–2.4 mS/cm EC depending on growth stage and plant type. Adjust to your specific crop requirements.
• Calibrate dose to soil background fertility: In heavily amended soils, start at the lower end of the recommended range and monitor plant response over 7–10 days before adjusting upward.
