    General Hydroponics Flora Nova Bloom Available in 1L, 4L, & 10L FloraNova 

    Any Plant, Any Media

    FloraNova is a breakthrough in a bottle. Its patented formula gives you the robust fertilizer strength usually found in a dry form, but with the quick application of a liquid. That means you can give your plants the nutrients they need, rapidly and easily. 

    This user-friendly fertilizer hybrid contains a unique combination of minerals and natural additives. It's ideal for all plants and multiple types of gardening.

    However you choose to garden, FloraNova delivers the nutrients all your plants require. No more guesswork about soil vs. soilless garden needs. And because it releases mineral and organic nutrients throughout the plant cycle, you can count on rapid growth from new starts all the way to fruits and flowers.

    Two Steps to Plant Nutrition
    FloraNova takes a two-step approach to bringing nutrients to your plants: 

    • FloraNova Grow supports and nourishes plants from their first moments of growth into later stages. It's also ideal for delivering needed nutrients to mother plants and new cuttings so you can establish them with confidence.
    • FloraNova Bloom, designed specifically for fruiting or flowering stages of growth, promotes vibrant color and higher yields.

    Calcium + Magnesium

    Calcium and magnesium are a necessary part of growth for many plants, but that doesn't mean they get as much as they need naturally. General Hydroponics CALiMAGic provides the supplemental elements necessary to optimize plant nutrition and to prevent all-too-common problems.

    A concentrated blend of readily available calcium and magnesium, CALiMAGic is a fully soluble product that won't clog spray lines or drip emitters, and can easily be combined with fertilizers.

    Mineral Magic
    Calcium-intensive plants require higher levels of the mineral to thrive and avoid issues with growth and production. 

    For instance, tomatoes that don't have enough calcium develop blossom end rot, a common disorder producing blackened, soft indentations that mar and weaken the fruits. Even if there's enough calcium in the soil, it may be blocked from getting to the plant because the pH is too low. Or, plants that are prone to magnesium deficiencies, such as peppers, suffer from yellowish and drooping leaves along with reduced disease resistance from root to flower.

    CALiMAGic delivers the power of calcium and magnesium in a form that prevents secondary nutrient deficiencies and builds stronger plant structure.

    General Hydroponics Kool Blooom Powder Available in 2.2lb, & 16lb

    For Flowers and Fruit

    Dry KoolBloom & Liquid KoolBloom are superior plant supplements that will substantially improve crop production and increase the weight of your yields. Liquid KoolBloom is used early and continually builds up flower production. Dry KoolBloom is used  late in the bloom phase to increase weight, yield and to encourage rapid ripening. Dry KoolBloom provides an intense final push at the end of the plant's life cycle. Use Liquid Kool Bloom at the beginning to maximize the effect of Dry KoolBloom at the end. Start with liquid, finish with dry.

    Beautiful blooms come from expert care. Liquid KoolBloom bolsters your efforts with essential nutrients your flowering plants need for vigorous growth, bigger blooms and increased flowering sites.

    For use between the vegetative and flowering phases, Liquid KoolBloom enriches plants with key components that increase nutrient uptake from roots to buds. With that level of nutrition, more of your buds will get what they need to reach the flowering or fruiting state, and develop into larger blooms or fruits.

    Great Roots, More Flowers
    Many types of flowering plants have young, delicate root systems that can be easily disrupted by external stressors, especially during the transition into the flowering and fruiting stage. 

    These challenges can negatively affect that plant cycle and cause buds to fail. Liquid KoolBloom's unique formula gets plants the key nutrients they require — all the way down to the roots — in a way that strengthens and promotes robust growth.

    Liquid KoolBloom is used early to build up flower production, while a companion product, Dry KoolBloom, focuses on the later stages of ripening.

    When flowering and fruiting plants are in their last stages of growth, how you address their unique nutrient needs will determine whether you get a bounty or just a bunch of buds. Get bountiful, with Dry KoolBloom.

    Specifically designed for that final push when buds transition to flowers or fruits, Dry KoolBloom is a nutrient supplement rich with phosphorous, potassium and other ripening elements. In combination, these components give plants precisely what they need, from roots to blooms, to be more productive and vigorous.

    Multiple Benefits
    In addition to increased flower density, Dry KoolBloom promotes greater oil and fragrance production along with faster ripening. Highly concentrated and cost effective, this supplement offers macronutrients that are primarily responsible for flower and fruit growth.

    Dry KoolBloom is used for the ripening stage to increase the intensity of the plant's flowering and fruiting process. A companion product, Liquid KoolBloom, focuses on the earlier stage of transition, from vegetative to flowering state. The combination of these two supplements forms the foundation of our most potent flowering and fruiting formula, bringing you increased yields and bigger, brighter blooms.

    Clean and Clear

    Over time, every hydroponic, soil-based or coco coir system can develop fertilizer residue as a natural part of the growing process. This accumulation can result in excess salts that will eventually cause your plants undue stress.

    Clear those concerns and get a cleaner system with General Hydroponics FloraKleen.

    Specifically designed to dissolve fertilizer salts, our solution not only flushes excess residue, but also releases a nutrient bond between plants and the system. This connection helps plants make the most of remaining fertilizers, especially in the crucial week just before harvest.

    General Hydroponics FloraNectar Available in 1L, 4L, 10L, & 23L

    Sweetener

    Even when fruiting and flowering plants are productive, an extra pop of powerful sugars can intensify sweetness and aromas. FloraNectar gives you that burst, in a unique blend designed to take your plant to the next level.

    FloraNectar is formulated with molasses and essential minerals to deliver numerous benefits for both plants and soil. It offers an ideal food source for beneficial microorganisms, increasing their growth rate to boost soil respiration. 

    The beneficial process of respiration releases carbon dioxide from the soil so that plants can use this naturally occurring chemical compound for growth. 

    Six Flavors, One Purpose
    FloraNectar comes in six flavor formulas: FruitnFusion, PineappleRush, BananaBliss, GrapeExpectations, SugarCane and BlueBerry Dream. These bring a higher degree of aroma to fruits and flowers. 

    No matter which formula you choose, FloraNectar will help your plants regulate key metabolism processes. This allows plants to achieve a balance between respiration and photosynthesis, leading to more abundant fruiting and flowering activity.
