General Hydroponics FloraSeries hydroponic nutrient 3-part trial pack, 1 qt, customizable feeding

The FloraSeries Trial Pack is a three-part hydroponic nutrient system (FloraMicro, FloraGro, FloraBloom) in 1 qt bottles that gives growers complete control over feeding at each growth stage.

Designed to let you create bespoke feeding regimens, this trial pack contains the core components of the trusted FloraSeries: FloraMicro, the foundational blend rich in nitrogen, calcium and chelated micronutrients; FloraGro, formulated to support structural and leaf development with nitrogen, phosphorus, potassium and magnesium; and FloraBloom, focused on phosphorus, potassium, magnesium and sulfur to encourage flowering and fruiting. These three concentrates are mixed into your reservoir in sequence so you can dial in ratios and timing to match plant needs, growing conditions, and desired results.

How do I use the three FloraSeries bottles together?

Add the concentrates to a clean reservoir of water one at a time, always starting with FloraMicro and stirring thoroughly before adding FloraGro and/or FloraBloom. Adjust amounts according to stage-specific feeding charts or your own recipe to supply primary, secondary and micronutrients in the proportions plants need.

• Start with a filled reservoir of fresh water.
• Add FloraMicro first and mix until fully dissolved.
• Introduce FloraGro and/or FloraBloom afterward, stirring between additions.
• Modify volumes to match vegetative or flowering phases and system size.

What nutrients does each concentrate supply and why does that matter?

Each bottle targets a specific nutrient role so you can tailor feeding to development phases. FloraMicro supplies nitrogen, calcium and chelated micronutrients as a base; FloraGro boosts structural and foliar growth with N-P-K plus magnesium; FloraBloom emphasizes phosphorus, potassium, magnesium and sulfur to support reproductive development.

• FloraMicro: nitrogen, calcium, chelated micronutrients for overall growth support.
• FloraGro: balanced N-P-K with magnesium to strengthen stems and foliage.
• FloraBloom: phosphorus, potassium, magnesium and sulfur for flower and fruit support.
• Combination feeding lets you alter ratios without changing product brands.

How does this trial pack help me fine-tune a feeding program?

Because the FloraSeries separates nutrients into three concentrates, you control dosage and timing for each nutrient group. That flexibility helps you respond to plant stage, water quality, and observed growth patterns, enabling incremental adjustments rather than wholesale formula changes.

• Mix-and-match dosing to create custom nutrient recipes.
• Respond to deficiencies or excesses by adjusting one bottle instead of all nutrients.
• Suitable for experimentation in small systems or as a sample before scaling up.
• Works with hydroponic reservoirs, ebb-and-flow, drip and other recirculating setups.

What safety and mixing steps should I follow?

Handle concentrated fertilizers with care: use clean measuring tools, add concentrates to water (never water to concentrate), and keep containers sealed after use. Follow label directions for dilution rates, store away from children and pets, and calibrate your reservoir volumes for accurate dosing.

• Add FloraMicro to fresh water first and stir until dissolved.
• Then add FloraGro and FloraBloom, mixing between additions.
• Wear gloves and eye protection when handling concentrates.
• Keep an accurate log of recipes and reservoir changes for consistent results.

Who is this for: The FloraSeries Trial Pack is ideal for hobby and small-scale hydroponic growers who want hands-on control of their nutrient program, gardeners testing the FloraSeries before committing to larger bottles, and anyone who prefers mixing bespoke feed recipes for different growth phases. It’s especially useful for growers who value adjustable nutrient ratios, need a compact starter set for experimentation, or run recirculating systems and want a reliable base of primary, secondary and micronutrients.
