The Pro Mix Kit 9.46 Liters Athena allows you to prepare homogeneous nutritional concentrates for indoor cultivation, reducing weighing errors and improving accuracy in each irrigation through Pro Core, Pro Grow, and Pro Bloom.

The Pro Mix Kit 9.46 Liters Athena is a complete mother solution preparation system designed for growers seeking consistency, speed, and nutritional control.
Each powdered component comes pre-dosed to be mixed in a 9.46-liter jug, avoiding the need to weigh small amounts of fertilizer for each preparation.
This way of working helps maintain a constant mineral composition between reservoirs, something especially important in indoor growing facilities with automated irrigation, fertigation, drippers, dosing pumps, or several cultivation sectors.
The kit works through a two-component nutritional strategy per phase: Pro Grow + Pro Core during growth and Pro Bloom + Pro Core during flowering.
Athena's dry fertilizers are formulated to dissolve completely, generate clean concentrates, and reduce the appearance of particles or sediments when mixed correctly.
The manufacturer recommends first preparing the concentrate and then using the necessary amount to reach the electrical conductivity indicated in the nutritional chart, instead of adding small portions of powder directly to the final reservoir.
This set belongs to the professional line of Athena fertilizers and brings together the three main products of the Pro program: Pro Core, Pro Grow, and Pro Bloom. The 2.5-gallon version includes three sachets of approximately 2.27 kg, three 9.46-liter mixing jugs, dosing taps, identification labels, and laminated preparation instructions. Each complete sachet is mixed inside the corresponding container, creating a concentrated mother solution ready to be dosed into the irrigation tank.
The format is practical for indoor crops where reservoirs are prepared frequently. The identified jugs allow each concentrate to be kept separate, while the taps make it easy to extract controlled amounts without constantly opening the containers. This organization reduces confusion between products and streamlines the daily preparation of the nutrient solution.
The Pro Mix Kit 9.46 Liters Athena is used to transform dry mineral fertilizers into standardized liquid concentrates. The main objective is to ensure that each reservoir receives the same proportion of nutrients, avoiding deviations caused by inaccurate scales, moisture in the powders, or differences during weighing.
During vegetative growth, Pro Core and Pro Grow are combined. This mixture provides a mineral base aimed at structural development, leaf formation, photosynthetic activity, and root growth. During the flowering stage, Pro Grow is replaced by Pro Bloom, keeping Pro Core as the base. The combination provides phosphorus, potassium, calcium, nitrogen, and microelements adapted to a phase with higher energy demand.
It also allows for organized work with fertigation systems, mixing tanks, injectors, and dosing equipment. The solubility of the Pro line helps keep pipes and drippers free of buildup when preparation, cleaning, and water quality are correct.
To prepare each concentrate, you must use a clean jug and reserve a different container for Core, Grow, and Bloom. It is recommended to work with reverse osmosis water or water with low conductivity, preferably warm, to facilitate dissolution.
Athena indicates that a 2,270-gram sachet should be completed up to approximately 9.5 liters of final solution. This means that the mark on the container represents the total volume of the concentrate, not the amount of water to be added initially.
During growth, the same proportion of Pro Core and Pro Grow recommended in the nutritional program is used. In flowering, Pro Core and Pro Bloom are applied. It is not advisable to mix the concentrates together in the same jug. Each concentrate should be added separately to the reservoir water, stirring between additions. Afterwards, it is necessary to check EC and pH before irrigation.
Pro Core provides nitrogen, calcium, and essential microelements. The formulation includes calcium nitrate and chelated micronutrients such as iron, manganese, copper, and zinc, as well as boron and molybdenum. These elements are involved in chlorophyll formation, plant structure, enzymatic activity, and various metabolic processes.
Pro Grow is formulated for the vegetative phase. It contains a mineral ratio aimed at growth, with available nitrogen and a set of macroelements and microelements. Athena states that Pro Grow does not contain urea or ammoniacal nitrogen, a feature designed to maintain controlled mineral nutrition.
Pro Bloom provides phosphorus, potassium, and microelements for flowering. The formula uses potassium sulfate instead of potassium nitrate, providing sulfur along with potassium. This composition is developed to meet the mineral needs of plants in stages of high metabolic activity.
It is a concentrate preparation kit that turns the Athena Pro dry line into three easy-to-measure liquid solutions. These are not three factory-prepared liquid fertilizer jugs, but a set with soluble fertilizers, graduated containers, and dosing accessories.
The main difference compared to manual weighing is that each bag contains the exact amount needed to fill a jug. This way, the grower does not need to calculate or divide the powder into numerous preparations. This feature improves repeatability and allows concentrates to be stored in an organized manner for use as the crop progresses.
The operation is based on preparing a mother solution of known concentration. Once each product is dissolved, milliliters of the concentrate are extracted and added to the final reservoir. The amount added will depend on the volume of water, the development stage, and the desired EC.
This method allows nutrition to be adjusted without handling dry fertilizer at each irrigation. It also favors automation, as the mother solutions can be connected to certain compatible injection or dosing systems. Athena describes the Pro line as a two-part formula per stage, developed for facilities seeking efficiency, control, and stability between mixes.
One of the main benefits is the reduction of weighing errors. By using complete sachets, the mineral ratio remains stable in each concentrate. It also reduces the time spent measuring powders and simplifies training for staff in charge of irrigation.
The high solubility makes it easy to prepare clean solutions compatible with numerous dosing equipment. In addition, the phase-separated system allows you to use only the necessary components: Grow + Core in growth and Bloom + Core in flowering.
Other notable benefits are ease of storage, clear identification of each concentrate, reduction of sediments, dosing by tap, and the possibility of preparing reservoirs uniformly. These advantages make the kit a suitable option for advanced grow tents, indoor rooms, hydroponic facilities, and projects with automatic irrigation.
