All-In-One Powdered Coco & Hydro Nutrient for Hard Water

Veg+Bloom Tap/Hard nutrient has been formulated to make life as simple as possible when growing in coco and hydroponic media, like rockwool, clay pebbles and Lava-Lite Hydro-Gro+. 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.

Tap/Hard formulated specifically for hard water areas, helping to neutralise alkaline water supplies. Tap / Hard is ideal for anybody with a starting EC over 0.3. If you're at 0.3 or below, check out RO/Soft.

It 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, which complicates things, takes up more time and leaves more room for error.

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