Key benefits of Hesi TNT Complex:

Explosive Growth – Provides fast and healthy vegetative growth thanks to organic nitrogen that’s easily absorbed by plants.
Enriched Formula – Includes vital nutrients, trace elements, vitamins and amino acids to promote all-round plant health.
Low EC Value – Offers high nutrient content without increasing electrical conductivity, protecting delicate root systems.
Gentle on soil – Low salt content ensures no root burn and keeps soil structure intact.
Easy to use – All products in the Hesi range are colour-coded with an easy-to-follow Hesi Grow Schedule, making it an ideal solution for inexperienced growers and experts alike.

Perfect for indoor and outdoor growers looking to maximise flower production with minimal fuss. Use at half strength for young plants and up to 5ml per litre for the remainder of the veg phase.

It is important to bear in mind that the majority of the Nitrogen content is organic-source nitrogen so you should not work to an EC reading when using this product.
