General Hydroponics MaxiBloom 5-15-14 - 50lb

Water-Soluble Dry Concentrate for the Reproductive Stage, 50lb

Fast-growing annuals moving into their reproductive stage need a complete, buffered nutrient profile without a grower having to blend one from separate salts. General Hydroponics MaxiBloom 5-15-14 is a water-soluble, pH-buffered dry concentrate built as a stand-alone bloom-stage feed for hydroponic and soil-based crops.

The 50lb size is built for commercial operations that mix large batches and want a bulk supply on hand.

Key Features & Benefits

• Complete Nutrient Profile — supplies primary, secondary, and micronutrients in one dry concentrate
• pH-Buffered Formula — helps stabilize feeding pH as the concentrate dissolves into solution
• Water-Soluble Concentrate — dissolves fully for hydroponic or soil-based systems
• Reproductive-Stage Formula — proportioned for the flowering and fruiting stage of fast-growing annuals

Who Should Use MaxiBloom

Growers of fast-growing annual crops who want a stand-alone dry concentrate for the flowering and fruiting stage, without blending a multi-part liquid system, will find MaxiBloom built for that role.

About General Hydroponics

Founded in 1976 by Lawrence Brooke out of a Berkeley, California garage, General Hydroponics became part of the Hawthorne Gardening Company brand portfolio, a subsidiary of The Scotts Miracle-Gro Company, in April 2015. MaxiBloom pairs with MaxiGro as a two-part dry-concentrate system covering vegetative and reproductive growth.

Frequently Asked Questions

What growth stage is MaxiBloom formulated for?

It is formulated for the reproductive stage of fast-growing annuals, when flowering and fruiting draw heavily on phosphorus and potassium. The complete profile also supplies the secondary and micronutrients that stage requires.

How do I mix MaxiBloom into a feeding solution?

Dissolve the measured dry concentrate directly into water following the rate on the feeding chart, with no second component required. The pH-buffered formula helps keep the resulting solution stable once mixed.

Is MaxiBloom a stand-alone fertilizer or part of a larger system?

It is designed as a stand-alone feeding solution, though many growers pair it with MaxiGro as an optional two-part system covering the full grow cycle. Used alone, it still supplies a complete reproductive-stage nutrient profile.

Does MaxiBloom work in soil as well as hydroponics?

Yes, it is formulated as a stand-alone feeding solution for both hydroponic and soil-based crops. Growers do not need a different dry concentrate for each type of setup.

What is the difference between MaxiBloom and MaxiGro?

MaxiBloom is formulated for the reproductive stage at a 5-15-14 ratio weighted toward phosphorus and potassium, while MaxiGro targets the vegetative stage at a nitrogen-forward 10-5-14 ratio. Most crops run MaxiGro through early growth and move onto MaxiBloom once flower sites appear.
