Booster PK+: a targeted supplement for flowering

Booster PK+ is a flowering supplement that provides phosphorus and potassium. The kit contains two 125 g sachets, which you can open and use separately. Its role is to supplement the base nutrient supply, so plan its use alongside what the plant already receives from the base feed and growing medium.

When introducing Booster, the combined composition of the base solution and supplement matters. If you add several nutrients to the water at once, record all the amounts added and check the finished solution. This keeps it clear, when making a later change, whether you adjusted the base nutrient dose, the supplement or the water volume.

The start and duration of flowering depend on the plant you have chosen. Time the use of Booster according to its dosing instructions and the actual development stage. The name of the kit and the recommendation for 1 m² do not, on their own, define a fixed weekly programme that can be used unchanged for every growing setup.

Water and growing medium together determine your starting point

The Mineral Feeding range can be used in soil, coco, rockwool and hydroponic systems under the appropriate application conditions. When choosing a medium, check whether it contains nutrients added in advance and which watering system you use. This information helps you select the manufacturer's nutrient feeding instructions suited to the setup.

Your source water may already contain dissolved minerals before you add the powders. Tap water, reverse-osmosis water and rainwater may require different approaches. If you do not know the water's composition, consider obtaining water quality information or professional advice. The amount already supplied by the water matters particularly when planning calcium provision.

An EC measurement provides information about the solution's electrical conductivity, while a pH measurement shows its acidity or alkalinity. The two values answer different questions, so they support checks together. Using the same water source and measurement method makes it easier to compare successive batches of solution and notice changes in the starting conditions.

Preparing the nutrient solution step by step

With powdered nutrients, accurate weighing and an accurate water volume are both important. First decide how much solution you want to prepare, then calculate the mass required according to the instructions for the particular product. Choose scales that can accurately measure the small doses you intend to weigh.

Use a clean container and tools for mixing. Carry out the final checks once all the nutrients you plan to add have dissolved, because this is when you can assess the solution that will actually be applied. The following sequence helps organise preparation; for the specific doses, always follow the instructions for the product and medium you are using.

1. Measure the water you will use and check its starting pH and EC. Record the water source too if you work with more than one type of water.
2. Choose a programme suited to the plant's development stage and growing medium. Check which product is needed on that occasion.
3. Calculate and separately weigh the amount of powder. For a dose specified in grams, measure in grams; check the mass rather than estimating by volume.
4. Add the required product to the water and mix thoroughly. If the programme also includes a supplement, add it as instructed.
5. Check the EC of the finished solution, then assess and, if necessary, adjust the pH according to the manufacturer's mixing instructions.
6. Record the water volume, products used, doses and measured values. Apply the solution in a way suited to your growing system.

Planning doses and quantities for your system

If the instructions give a dose per litre of water, calculate it using the number of litres you intend to prepare. This lets you make different solution volumes from the same recipe and keep track of how quickly the pack is being used. Calculate Grow, Hybrids and Booster separately, because the amount available of each differs.

The recommendation for approximately 1 m² helps you assess the size of the kit, but the number of waterings and water used each time also matter alongside the area. Writing down the planned solution volumes in advance lets you estimate which component will be used more. Update this estimate during actual use, because the plants' water uptake may change with their development and the conditions.

When changing nutrient programmes, also review the products used previously. If a product from another manufacturer remains in the system, you need to consider its composition and application conditions as well. This helps you avoid planning the same supplement from several products on top of one another. Record the changeover date and new recipe too, so that successive waterings can be clearly traced later.

Observation and changes you can track

In a brief growing log, the date, development stage and watering details together are much more useful than isolated measurement figures. Note alongside them any change in the water source, growing medium or nutrient solution composition. These records may later help you understand the conditions in which you applied a particular dose.

If a plant's appearance changes, examine watering and environmental conditions as well as nutrients. A symptom alone is not enough to choose the appropriate action. Measured values, previous treatments and plant development together provide a better basis for making a decision. In an uncertain situation, recorded information makes it easier to request targeted advice.

Storage and keeping mixing equipment clean

Reseal the sachets after use and follow the storage instructions on the label. Use a clean, dry tool to measure the powder and keep the open pack away from the mixing water. One of the two Booster sachets can remain unopened until later if you initially need only the contents of the other.

After use, clean mixing containers and measuring equipment according to the equipment manufacturer's instructions. Label the prepared solution to show what it contains, particularly if you use several containers at once. Clearly identified packs and records also make accurate work easier the next time you mix a solution.

Safe preparation and application

Before use, read the label on each sachet and the products' safety data sheets. Choose the necessary protective equipment and handling and storage conditions based on these documents. Grow, Hybrids and Booster are separate products, so each has its own instructions.

Carry out weighing on a separate, organised work surface and keep the nutrients in clearly identifiable packaging. Follow the label and safety data sheet when dealing with any spilled solution or powder as well. A carefully prepared workflow forms the basis of both accurate dosing and safe use.

Frequently asked questions about the Mineral Starter Kit

Exactly how long will the kit last?

How long it lasts depends on the volume of solution prepared and the dose of each product. The recommendation for approximately 1 m² gives you a reference for the area; you can estimate a specific duration alongside your own watering and nutrient feeding plan.

Could a separate calcium supplement be needed?

This depends on the composition of the water and medium. The specified kit contains Grow, Hybrids and Booster products. Decide on separate supplementation using your source water information and the manufacturer's recommendations, particularly when using soft or reverse-osmosis water.

Is the sachet weight enough to determine the dose?

The pack size shows how much nutrient is available. To determine a single dose, you also need the particular product's application instructions, the water volume and the growing conditions. The scales help you accurately weigh the mass you have calculated.
