Mills Basis A&B — Bioavailable Base Nutrient

Mills Basis A&B — Bioavailable Base Nutrient

Not all base nutrients are created equal. Mills Basis A&B uses top-quality raw ingredients with a specific focus on bioavailability — meaning your plants actually absorb what you're feeding them, rather than leaving it locked in the reservoir. A favourite of serious growers who've tried everything and settled on Mills for consistency.

Why growers choose Mills Basis A&B:

• Bioavailability-focused formulation — nutrients in forms plants can actually take up, not just whatever's cheapest on the chemical market
• Complete macro and micronutrients — N, P, K, Ca, Mg plus full trace element profile, balanced for real plant demand
• Works across veg AND flower — one base nutrient through the whole grow, add boosters as needed
• Forgiving for novice growers — well-buffered, pH-stable, hard to over-feed when used as directed
• Tuneable for advanced growers — experienced users can adjust ratios for specific crops and conditions
• Premium Dutch brand — Mills has built a reputation on quality raw materials and consistent batch-to-batch

Who it's not for:

Mills works across hydro, coco and soil but is often priced above entry-level base nutrients — for first-time growers on a budget, Canna or HydroTops base are more approachable. If you're running a strict organic grow, check Mills' organic certification status against your requirements. Always use the A and B bottles together at the dilution on the label.
