Botanicare Nutrients, Growing Supplies & Flood Trays
Botanicare is one of the most established brands in North American hydroponic horticulture, with a product lineup spanning nutrient solutions, plant supplements, growing accessories, and the flood trays that have become the category standard in ebb and flow growing. Their Cal-Mag Plus calcium and magnesium supplement is among the most widely used Ca-Mg products in hobby and commercial hydroponics; their Pure Blend Pro and Readygro soil amendment product lines cover a broad range of grower preferences from mineral hydroponic programs to organic and transitional soil approaches.
Botanicare Nutrients
Botanicare's nutrient lineup is anchored by Pure Blend Pro -- a one-part complete nutrient formula available in Grow and Bloom formulations, designed to simplify feeding to a single-product program while still covering the full macro and micronutrient profile required for complete plant nutrition. Pure Blend Pro Grow and Bloom are compatible with soil, coco, and hydroponic systems and are popular among growers who want a straightforward program without the complexity of a three-part system. Botanicare also produces the CNS17 line -- a professional-grade mineral nutrient concentrate in separate Grow, Bloom, and Ripe formulas for growers who want more stage-specific control. Liquid Karma (organic bio-stimulant) and Silica Blast (potassium silicate supplement for structural strength) round out the core product lineup.

Botanicare Cal-Mag Plus
Botanicare Cal-Mag Plus is the most widely used calcium and magnesium supplement in hobby hydroponics -- a liquid formula containing 3.2% calcium, 1.2% magnesium, and 0.1% iron, with 2% nitrogen as an amino-acid nitrogen source. It is the standard recommendation for soft water, RO water, and coco coir grows where calcium and magnesium supplementation is essential from transplant through late flowering. Add Cal-Mag Plus to the reservoir before base nutrients at 2-5 ml per gallon depending on water baseline and growing medium.

Botanicare Flood Trays & Growing Accessories
Botanicare's flood trays are the industry standard for standardized inside dimensions in ebb and flow growing -- available from 1x1 to 4x8 ft in black and white configurations, with true inside dimensions that make plant count and container layout planning straightforward. Their slide bench rolling system is one of the most widely deployed commercial rolling bench platforms in North American CEA operations.

Botanicare FAQ
What nutrients does Botanicare make?
Botanicare's main nutrient lines are Pure Blend Pro (one-part Grow and Bloom formulas for simplified single-product feeding programs) and CNS17 (professional mineral concentrates in Grow, Bloom, and Ripe formulas for stage-specific control). Cal-Mag Plus (calcium, magnesium, and iron supplement) is their most widely used standalone product across all growing programs. Supplement products include Liquid Karma (organic bio-stimulant for enhanced nutrient uptake), Silica Blast (potassium silicate for structural strength), and Aqua Shield (beneficial microbial inoculant for root zone health).
What is the difference between Botanicare Pure Blend Pro and CNS17?
Pure Blend Pro is a simplified one-part formula -- a single bottle covers the full nutrient profile for each growth stage. It is the most accessible entry point in the Botanicare lineup, well-suited for growers who want a straightforward program without multi-part mixing. CNS17 is a professional-grade mineral concentrate in three separate stage-specific formulas (Grow, Bloom, Ripe), offering more precise stage-specific nutrient ratios at the cost of more components to manage. CNS17 is popular with commercial operators who want Botanicare's formulation approach with more stage-specific control. Both work across hydroponic, coco, and soil growing media.
How do Botanicare flood trays compare to other brands?
Botanicare flood trays are the category standard for standardized inside dimensions -- their 4x4 tray measures true 4 ft x 4 ft inside, making container layout and plant count planning straightforward. Competitor trays often list outside dimensions, creating confusion when fitting containers inside. Botanicare's slide bench rolling system integrates directly with their tray product line and is the most widely deployed commercial rolling bench platform in North American CEA operations. For growers comparing Botanicare to Active Aqua or Duralastics trays, the Botanicare premium is justified by the consistent inside dimension standard and the availability of a matched commercial bench ecosystem.
How much Cal-Mag Plus should I use per gallon?
Standard dosing for Botanicare Cal-Mag Plus is 2-5 ml per gallon. Starting point: 2-3 ml/gallon for soft tap water or RO water in hydroponic systems; 3-5 ml/gallon for coco coir grows where the medium buffers calcium and magnesium from solution. Add Cal-Mag Plus to the reservoir first before your base nutrients, then adjust pH after all products are mixed. In RO water programs, Cal-Mag Plus at 3 ml/gallon is essentially mandatory as a baseline supplement -- RO filtration strips calcium and magnesium along with other dissolved solids, leaving water deficient in both for plant growth requirements.
