General Hydroponics – Feed Charts, Nutrients & Full Kits

The General Hydroponics Flora Series is the foundation of the brand's nutrient lineup and one of the most widely used three-part nutrient systems in professional and home growing. General Hydroponics flora grow, flora bloom, and micro work together as a complete nutrition system — each one targeting a specific function, and all three designed to be used in combination throughout the plant's life cycle. Flora Grow supports vegetative development, providing the nitrogen and potassium profile that plants need during their early and mid-growth phases. Flora Micro delivers essential micronutrients and calcium support that underpin every stage. Flora Bloom shifts the nutritional balance toward phosphorus and potassium to drive flowering and fruiting.

The power of the General Hydroponics 3 part system is in the flexibility it gives growers. By adjusting the ratio of each component, you can dial in exactly the nutritional profile your plants need at any given point in their development — something a single-bottle nutrient cannot do. The gh3 part nutrients flora series is used across hydroponic, aquaponic, and soil-based growing methods, which is why it appears on feeding charts for such a wide range of cultivation setups. The General Hydroponics trio is the most practical way to purchase all three components together, ensuring you always have the complete system on hand rather than running short on one part mid-grow.

For growers moving from general nutrient products to a more structured approach, the General Hydroponics flora feed chart provides specific mixing ratios for each growth stage — seedling, vegetative, transition, bloom, and late bloom. The General Hydroponics florapro feed chart extends this guidance for more advanced cultivation systems. Following the gh feed chart takes the guesswork out of nutrient mixing and ensures that what goes into the reservoir or soil matches what the plant actually needs at that point in its development. Whether you are running a recirculating hydroponic system or feeding into soil, the chart-based approach that General Hydroponics builds its products around is what makes the Flora Series consistent and repeatable across grows.

Nutrient uptake in any growing system — hydroponic, soil, or aquaponic — is directly tied to pH. If the pH of your nutrient solution or growing medium is outside the optimal range for your crop, plants cannot absorb the nutrients that are present, regardless of how well-formulated the fertilizer is. General Hydroponics ph down and up products are the standard solution for this: pH Down Liquid lowers the pH of an overly alkaline solution, and pH Up Liquid raises it when the solution is too acidic. The General Hydroponics ph up and down range is formulated for precision — small measured additions produce predictable, stable adjustments rather than swings that overcorrect.

The ph for fertilizer application context matters because different nutrients affect pH differently when mixed. The General Hydroponics feeding chart accounts for this — it gives mixing guidance that takes the pH impact of each nutrient component into consideration, reducing the number of adjustments needed after mixing. The General Hydroponics up/down products are used after mixing to fine-tune the solution to the target range for your crop and growing method. Flora plant nutrient and ph control work together as a system: the nutrients provide the feed, and the pH products ensure the feed is actually available to the plant's root system.

For growers using General Hydroponics nutrients in soil rather than hydroponic systems, the General Hydroponics feed chart soil version provides the adjusted ratios and pH targets appropriate for soil-based growing. Soil buffers pH more actively than hydroponic water, which changes both the mixing ratios and the target pH range. The General Hydroponics chart for soil growing is a practical starting point that removes the trial-and-error period many growers go through when transitioning from hydroponic to soil or vice versa. The General Hydroponics ph down and up products work equally well in both contexts — the application method changes, but the chemistry and precision of the products remain the same.

The General Hydroponics starter kit is the most efficient way to begin working with the Flora Series system. The kit General Hydroponics puts together typically includes the core three-part nutrients, pH control products, and the measuring and mixing equipment needed to set up a functioning nutrient program from day one. The General Hydroponics kit removes the uncertainty of assembling a nutrient program from individual components — everything included is formulated to work together, and the ratios are based on the General Hydroponics feeding chart that the brand has refined across decades of grower data. For new growers, this means a faster start with fewer mistakes. For experienced growers setting up a new system, it means a complete baseline in one order.

Beyond the core Flora Series, general hydroponic products extend into supplemental nutrition that addresses specific growth challenges. The General Hydroponics bloom booster supports the transition into and through the flowering phase, adding targeted phosphorus and potassium above the baseline provided by Flora Bloom. The gh flora + calimagic combination is particularly relevant for hydroponic systems, where calcium and magnesium — two nutrients that soil provides passively — need to be actively supplemented in the reservoir. CALiMAGic provides both in a single concentrated formula that integrates cleanly into any General Hydroponics feeding program without disrupting the pH balance of the overall solution.

The General Hydroponics grow chart and General Hydroponics nutrients bloom guidance that comes with the product range is what makes the supplemental products easy to incorporate without overfeeding. General hydroponics series products are all designed to work within the same feeding framework — the base nutrients, the pH control, the supplemental boosters, and the root enhancement products all reference the same chart-based approach. Gen hydroponics as a system works because every product has a defined role and a defined point in the feeding schedule where it belongs. General hydroponic fertilizer products across the range are concentrated, which means a small bottle covers a large number of feeds — and the General Hydroponics feeding guidance ensures you use the right amount at the right time rather than guessing at application rates. The result is a complete, chart-driven nutrition program that works consistently across general hydroponic growing environments from the first seed to the final harvest.
