General Hydroponics Diamond Nectar Nutrient Additive - 1 gal

In this review of General Hydroponics Diamond Nectar 0-1-1, the bottom line is simple: growers who want a versatile, easy-to-use nutrient additive for a wide range of plants will appreciate this product. Our review found it works equally well in soil, soilless mixes and hydroponic solutions, and can be applied as a foliar spray, making it a solid choice for hobbyists and small-scale commercial growers alike. The single biggest reason to buy is its broad compatibility with fertilizers and pH ranges, which reduces guesswork when mixing feeding regimens.

Key Features

• Versatile application: Can be used on vegetables, row crops, trees, ornamentals and landscaping, allowing one additive to cover many plant types.
• Multiple growing media: Safe to add to soil, potting mixes, soilless rooting media and hydroponic solutions for consistent use across systems.
• Foliar or root feeding: Can be applied as a foliar spray or added to fertilizer mixes, offering flexibility in how nutrients are delivered.
• Fertilizer compatible: Formulated to be compatible with all fertilizers so it can integrate into existing feeding schedules.
• Wide pH tolerance: Usable across pH ranges and all soil types, which simplifies management in variable growing conditions.

Who It's For

This product is ideal for gardeners, greenhouse operators and hydroponic growers who want a single additive that can be used across many crops and systems. It suits users who prefer simple compatibility with existing fertilizers and those who switch between soil and soilless setups or who run mixed plantings.

Less suitable for growers seeking a complete standalone fertilizer with a full N-P-K balance, as this is a targeted additive with an N-P-K of 0-1-1 intended to complement base nutrients rather than replace them.

Pros & Cons

Pros

• Broad compatibility with fertilizers and pH ranges makes it easy to add to most feeding plans.
• Works across many plant types and growing media, reducing the need for multiple specialty products.
• Can be applied as a foliar spray for direct uptake or added to nutrient solutions for root feeding.

Cons

• Not a complete fertilizer by itself-its 0-1-1 formulation is an additive and must be used with a base nutrient program.
