Shop hydroponic base nutrients at A-Grade Hydroponics — trusted A+B formulas for coco, soil, DWC and NFT systems, built for stronger roots and bigger yields.
Hydroponic base nutrients are the primary feed source for plants grown without soil, supplying the core macro and micronutrients needed at every growth stage. Whether you're running a coco coir tent at home or a full NFT system, our range covers A+B two-part formulas for growth and bloom, suited to beginners through to experienced commercial growers.
Base nutrients are the single most important input in any hydroponic setup — without a properly balanced feed, even the best lighting and system design won't produce healthy, high-yielding plants. A good base nutrient delivers correct nitrogen, phosphorus, potassium and micronutrient ratios (EC and pH-stable) across vegetative and flowering stages, supporting strong root development, vigorous foliage and improved bud or fruit set.

How to choose
Coco vs. soil vs. hydro formulations
Coco and hydro systems need a base nutrient formulated for run-to-waste or recirculating feeding, while soil growers benefit from a slower-release, buffered formula — check the label for your medium before buying.
Beginner vs. experienced
If you're just starting out, a simple two-part A+B base is the easiest to dial in and forgives minor dosing errors. Experienced growers running precise EC/pH schedules may prefer a base designed for layering with boosters and additives.
Growth vs. bloom
Most base nutrients are sold as separate growth and bloom formulas — growth formulas favour nitrogen for foliage, bloom formulas shift toward phosphorus and potassium for flowering and fruiting.
