Nutrient solution preparation kit for soilless cultivation
Educational kit for preparing stock and working nutrient solutions, learning pH/EC measurements and practising basic hydroponics laboratory techniques.
Students use the kit to prepare stock and working nutrient solutions, measure pH and EC, and practise basic hydroponics laboratory techniques. They study nutrient media and the principles of soilless cultivation, learning to weigh substances, dissolve them in stages, make solutions up to volume and label containers. EC and pH measurements help them assess whether a solution is suitable for cultivation and understand why concentrates A and B are stored separately.
