MILLS BASIS A 1LTR

Precipitation-Free Base Nutrition, Part A, 1 LTR

Concentrated base nutrients that combine calcium and phosphate compounds in a single bottle risk precipitation, clouding the concentrate and clogging dosing equipment before it ever reaches the reservoir. Mills Basis A is formulated as one half of a two-part base nutrient system, keeping its mineral profile separated from Basis B's until both are diluted together in the feeding solution.

At 1 LTR, this size suits trial and hobbyist growers testing Mills Basis A on a single reservoir before committing to a larger bottle.

Key Features & Benefits

• Two-part base nutrient system — keeps incompatible mineral compounds separated at concentrate strength, preventing precipitation in the bottle.
• Liquid concentrate formula — mixes directly into reservoir water alongside Basis B at a 1:1 ratio.
• Used as the foundation of a full feeding program — supports base nutrition across vegetative and flowering stages when paired with Basis B and any supplemental additives.
• Consistent formulation across bottle and bulk sizes — delivers the same concentrate strength whether dosing from a 1LTR bottle or a 1000LTR tote.
• Part of the Mills Nutrients line — designed to work as a matched base system with Basis B rather than as a standalone fertilizer.

Who Should Use Mills Basis A

Growers running a base nutrient program who need Basis A dosed alongside its Basis B counterpart, from home growers dosing a single reservoir to commercial operations feeding at scale.

About Mills Nutrients

Mills Nutrients formulates two-part base nutrient systems for hydroponic and soil feeding programs, splitting incompatible mineral compounds across an A and B bottle so growers get full nutrient concentration without precipitation risk.

Frequently Asked Questions

Why is Basis A sold separately from Basis B instead of as one bottle?

Combining certain calcium and phosphate or sulfate compounds at full concentrate strength causes precipitation, so the two-part system keeps each half stable until they're diluted together in the reservoir.

Can Basis A be used without Basis B?

No, it's formulated as one half of a matched two-part base system and is intended to be dosed alongside Basis B at a 1:1 ratio, not as a standalone fertilizer.

How is dosing consistent between a 1LTR bottle and a 1000LTR tote?

Both are manufactured to the same concentrate strength, so dosing rate scales directly with reservoir size regardless of which container size a grower purchases from.

Can Basis A and B be used alongside supplemental additives?

Yes, the two-part base system is designed as the foundation of a feeding program, with growers typically layering in bloom boosters or other additives on top while tracking total feeding strength.

How should Basis A be stored between uses?

Store the concentrate in a cool location out of direct sunlight and reseal the container tightly after each use to maintain consistency between doses.
