FloraSeries Hydroponic Nutrient System (1 pt)
The FloraSeries package provides FloraMicro, FloraBloom, and FloraGro—each engineered to meet cannabis plants’ changing needs from vegetative growth through flowering. FloraMicro supplies nitrogen, calcium, and chelated micronutrients to support rapid development, while FloraBloom and FloraGro target bloom initiation and strong structural growth. The three-part system enables precise control over nutrient ratios to optimize uptake and plant health in hydroponic, coco coir, or soil-based setups.
Base A & B Two-Part Hydroponic Formula
Humboldts Secret Base A & B deliver a complete, balanced nutrition set with essential macronutrients (NPK) and secondary elements like calcium and magnesium. The two-part system simplifies feeding—just mix equal parts of Base A and B with every watering. It works across deep water culture, coco, traditional soil, and other grow media, making it versatile for home grows and small commercial setups. Regular weekly feeds promote steady vegetative growth and consistent flowering potential.
CALiMAGic 1-0-0: Calcium & Magnesium Blend
CALiMAGic delivers a concentrated blend of readily available calcium and magnesium to address common secondary nutrient deficiencies in fast-growing cannabis plants. It helps prevent blossom end rot and tip burn, supporting healthier fruit formation and leaf integrity. This supplement integrates with hydroponic or soil systems, making it a practical add-on when Fe and Ca/Mg balance becomes an issue during rapid growth or stress periods.
Flora Series 3-Part Nutrient System (1 qt)
This 3-part formulation mirrors the FloraMicro, FloraBloom, and FloraGro components in a compact, quart-size setup. It is designed to fulfill cannabis plant nutrient needs across growth phases by providing nitrogen-rich micro nutrients, balanced phosphorus and potassium, and essential trace minerals. The three-part approach enables precise delivery and adaptation to plant demand, enhancing growth consistency in hydroponic gardens and alternative media alike.
FloraSeries Trial Pack: FloraMicro, FloraBloom, FloraGro
The FloraSeries trial pack provides the core trio—FloraMicro, FloraBloom, and FloraGro—in a compact sampler. It is ideal for growers evaluating the three-part system or adjusting feeding regimens for cannabis cultivars during different growth stages. The nutrients are formulated to support robust vegetative growth and steady transition into flowering, with chelated micronutrients that aid uptake in hydroponic environments.
FloraSeries Trial Pack (1 qt) – Alternate
This alternate FloraSeries trial pack echoes the core nutrition suite of FloraMicro, FloraBloom, and FloraGro in a 1-quart size. It is suitable for growers seeking flexibility in mixing and adjusting nutrient ratios as cannabis plants progress through growth stages. The balanced formula helps maintain steady uptake and supports plant vigor in hydroponic and soilless environments.
VIVOSUN Base A & B Bundle
The VIVOSUN Base A & B bundle provides a two-part, comprehensive nutrient system designed for fast vegetative growth through flowering. It includes macro- and micronutrients that promote rapid, healthy development and higher yields. The water-soluble formula stabilizes nutrient solution pH and improves nutrient absorption, supporting consistent performance in home grows, especially for cannabis cultivators who rely on repeatable feeding schedules.
Buying Guide: Key Purchase Considerations
- Grow medium compatibility: Ensure the nutrient system works with your setup (deep water culture, coco coir, soil, or a mixed media approach).
- Growth stage targeting: Three-part systems (like FloraMicro/FloraBloom/FloraGro) allow precise control across vegetative and flowering phases, while two-part blends simplify feeding schedules.
- Calcium and magnesium needs: Supplements such as CALiMAGic can prevent common deficiencies in rapidly growing cannabis plants.
- Ease of use: For beginners, pre-mixed or trial packs may reduce guesswork; seasoned growers may prefer modular components to tailor formulas.
- Stability and solubility: Choose nutrients that dissolve cleanly in water and maintain stable pH to avoid lockout and deficiencies.
- Media versatility: If you rotate between hydroponics, coco, and soil, select products known to perform well across media.
- Availability and support: Widely available brands with clear feeding guidelines help maintain consistent schedules and results.
- Cost-per-use: Consider bottle size, dilution ratio, and frequency of feeding to estimate long-term cost per grow.
