CitySens Mineral Plant Nutrients – 300 ml for Hydroponics, Indoor and Soil Plants

Description

CitySens Nutrients is a 300 ml bottle of mineral plant nutrients developed to support healthy growth in both hydroponic systems and soil-based plants. This nutrient mix is designed for indoor gardening, soilless growing and everyday plant care, and it can also be used for flowering plants and orchids grown in pine bark. The formula combines 14 mineral elements that plants need for balanced development. While many conventional nutrients include fewer elements, CitySens nutrients include a broader mineral profile with the elements provided in their intended proportions for steady growth.

Getting the nutrient concentration right is one of the most common challenges in hydroponics and smart gardening. Too little and plants stall; too much and you risk salt stress or nutrient burn. The free EC & Nutrient Calculator takes the guesswork out of it — enter your reservoir size, tap water EC, and target crop, and it tells you exactly how much nutrient solution to add.
