General Hydroponics MaxiGro & MaxiBloom 2.2 lb Bundle — Vegetative and Flowering Water-Soluble Nutrients

General Hydroponics MaxiGro and MaxiBloom bundle provides stage-specific dry nutrients formulated to support vigorous vegetative growth and robust flowering in hydroponic and soil systems.

These two complementary powdered fertilizers come in a combined 2.2 lb package designed to feed plants through both the growth and bloom cycles. MaxiGro supplies a balanced profile of nitrogen and supportive elements for leafy development, while MaxiBloom shifts the ratio toward phosphorus and potassium to encourage flowering and fruit set. Because they are water-soluble, both products dissolve quickly for easy mixing in reservoirs, hand-watering, or drip systems.

How do these nutrients fit into a hydroponic schedule?

Use MaxiGro during the vegetative phase to promote strong stems and abundant foliage, then transition to MaxiBloom when you want to prioritize buds, blossoms, or fruit. Follow feeding charts for concentration and frequency to avoid overfeeding and keep EC/pH monitored. The switch typically happens at the start of the flowering cycle or after transplanting to a bloom-focused environment.

• MaxiGro for vegetative stages: higher nitrogen for leaf and stem growth
• MaxiBloom for flowering: increased phosphorus/potassium balance
• Water-soluble powder: mixes quickly for reservoirs and hand applications
• Use recommended dosing and monitor EC/pH for best results

What mixing and application steps should I follow?

Dissolve the recommended grams of powder into warm water separately before adding to the main reservoir to ensure even distribution. Always add nutrients to water, not water to nutrients, and stir until fully dissolved. After mixing, measure electrical conductivity and pH and adjust as needed for your crop and growth stage.

• Dissolve each formula thoroughly in a container before adding to your system
• Measure and adjust EC and pH after mixing to match crop needs
• Replace solution on a regular schedule to prevent salt buildup
• Store unused powder in a cool, dry place away from humidity

Will this bundle work in soil as well as hydroponics?

Yes — these water-soluble formulations are suitable for both soilless and soil applications when used at appropriate rates. For potted soil, use reduced concentrations and monitor plant response; in hydroponic reservoirs, follow full guidance for nutrient strength. Adjust frequency and volume based on container size and plant demand.

• Hydroponic reservoirs: follow full-strength feeding charts
• Soil and containers: use diluted solution and less frequent applications
• Ideal for drip, ebb-and-flow, and hand-watered systems
• Observe plants and adjust concentrations to avoid nutrient burn

How should I store and handle the powders safely?

Keep containers sealed in a cool, dry area out of direct sunlight and moisture to maintain product stability. Use gloves and eye protection when measuring and mixing concentrated powders to avoid irritation, and clean tools and mixing vessels after use to prevent residue buildup. Dispose of any unused mixed solution according to local guidelines.

• Store dry, sealed, and away from humidity
• Use protective gloves and eyewear when handling concentrates
• Clean mixing equipment to prevent cross-contamination
• Follow local disposal rules for leftover nutrient solutions

Who is this for: Growers seeking a straightforward, stage-specific nutrient system will appreciate this MaxiGro and MaxiBloom bundle. It’s suitable for hobbyists and experienced cultivators using hydroponic, soilless, or container gardens who want an economical way to feed plants through vegetative and flowering cycles. If you prefer easy-to-mix dry formulas that let you control concentration and timing, this bundle offers flexibility and proven compatibility with common greenhouse and indoor systems.
