Hesi TNT Complex is a nutrient for young plants or mother plants grown in soil or coco coir. Hesi TNT Complex should be used during the vegetative phase of plant growth. Switch to Hesi Bloom Complex when your plants start to flower in soil, or Hesi Coco for plants flowering in coco. The NPK percentages of Hesi TNT Complex are Nitrogen 3%, Phosphorus 2.3%, Potassium 3.1%. Use 2.5ml per litre for clones and mother plants, and 5ml per litre for growing plants, indoors and outdoors. Hesi TNT Complex contains all the nutrients your young plants and mothers will need, as well as vitamins, active sugars, and amino acids to ensure healthy growth. The Nitrogen in Hesi TNT Complex is 100% organic, meaning less salts and in turn improved growing conditions for young plants. (The fact that the Nitrogen is 100% organic results in a low EC value. Be careful not to overfeed, as this can lead to leggy plants that will struggle to get vital nutrients from the roots to the tips of the plants in the bloom cycle.) Hesi TNT Complex also contains all the nutrients your young plants and mothers will need, as well as vitamins, active sugars, and amino acids to ensure healthy growth. If you wish to use additives with Hesi TNT Complex, we recommend using Hesi Supervit throughout the grow and bloom cycles, at the rate of 1 drop per 4.5 litres of water. Also consider Hesi Root Complex to encourage vigorous root growth and to assist when plants are stressed, and Hesi Powerzyme – used once or twice a week - to keep the plant medium in optimum condition throughout the grow
