All-In-One Powdered Base Nutrient for Soil

Veg + Bloom Dirty nutrient has been formulated to get the best out of soil-based growing media. Hydroponic Research nutrients are powdered nutrients formulated for growers operating at huge scales, where tiny differences in performance have huge pay-offs. They're designed to squeeze as much as possible from your plants, which explains why customer feedback on this range has been exceptional.

Dirty contains all of the macro and micronutrients needed for optimal plant health, and also packs in amino acids, fluvial acids, bio active growth stimulants and silica. The team at Hydroponic Research have combined an array of bottles into one powder, saving you money as well as lots of time and effort. Many other nutrient ranges force you to buy a lot of the ingredients separately.

The range couldn't be simpler, and Dirty has enough nutrient content to get you through a full grow. We'd suggest adding some Shine, from week three of flower. It's loaded with phosphorus and potassium (PK 22-12), which will help to push fruit development as far as possible.
