Maxi Series

Family Overview – Maxi Series
The Maxi Series is a two-part, dry, water-soluble base nutrient line built around potent, stand-alone formulas: MaxiGro for vegetative growth and MaxiBloom for flowering and fruiting. Both are single-part, milled dry concentrates that mix cleanly into solution, are easy to use in day tanks of any size, and are versatile enough for both hydroponic and soil-based environments. With appropriate levels of primary and secondary nutrients, MaxiGro and MaxiBloom are concentrated enough for commercial scale, yet still come with a mess-free scoop for smaller growers.

How the Maxi Series Program Works

  • MaxiGro is used from seedling/cutting through the vegetative growth stage.

  • MaxiBloom is used when plants move into flowering and fruiting.

  • Each product is a stand-alone, single-part formula; you run one at a time based on growth stage.
