It was found that plants thrive well on a mineral substrate. Around 1970, the material was first used for cultivating plants. Scientists discovered that plants can absorb the nutrients they need from water and that soil is not always necessary. The mineral (hydroponic) substrate can absorb a large quantity of water while also holding a very high percentage of air. This is an ideal opportunity for professional plant cultivation. Product information The main advantage of growing on substrate is that it allows the nutrient supply to be regulated and optimised. The House and Garden Hydro A\u0026amp;B nutrient base is primarily intended for this growing method. It is also free from contaminating ballast substances, ensuring that the substrate's hygroscopic capacity is fully preserved and utilised. The unique composition of pure, high-quality nutrients from various elements, including EDDHA iron, allows the plant to feed quickly and efficiently during both the growth and flowering periods. Achieving an optimal effect The main advantage of cultivation on a mineral (hydroponic) substrate is that it enables regulation and optimisation of nutrient supply. The House and Garden Hydro A\u0026amp;B nutrient base is entirely geared towards this cultivation method. Thanks to its unique composition of different elements, Hydro A\u0026amp;B is the right choice to provide your plants with all the nutrients they need during both the growth and flowering periods. Preparing the nutrient reservoir Fill two thirds of the reservoir with water. Add A first. Mix well. Add B and mix well. Adjust the EC value: start the growth cycle at EC 1.2, increase gradually according to the growth schedule until the end of flowering, and finish at EC 2.0. Add pH- (down) or pH+ (up) for nutrient solution adjustment to maintain a value from 5.7 to 6.7. Fill the reservoir to the top with water. If necessary, use root-growth or plant-flowering stimulators. Your nutrient reservoir is now ready for its first watering. Tap-water EC value + Nutrient Hydro A\u0026amp;B EC value = EC of ready-to-use nutrients. Tip Do not add Hydro A and Hydro B at the same time. This will lead to incomplete nutrition, precipitation and clogging. Use calibrated EC values and pH meters. Before planting, thoroughly moisten the substrates (+\/- 90% moisture) for optimal absorption. Fill the substrate or growing container with water at a light nutrient concentration according to EC 1.2 and leave for one day. Cut the bottom of the substrate or open the growing container and allow excess water to return to the nutrient reservoir. The substrate is now ready for planting. From now on, keep the substrate slightly drier to allow the plant's roots to seek nutrients and water. This will prevent the plant from becoming lazy. Quantity and available pack sizes 1 litre for every 250 litres of ready-to-use nutrients 1, 5, 10 and 20 litres.\u003c\/p\u003e\n\u003cp\u003eHydro A\u0026amp;B Basic Nutrients.
