Gold Label Hydro Round Substrate

Gold Label Hydro Round substrate is specifically designed for growing hydroponically. Dutch quality medium for hydroponics.

Gold Label Hydro round 8-16 expanded clay pebbles have a very solid outer ceramic layer, which limits the uptake of water. They are ideally suited for intense irrigation hydroponic styles of growing. Be aware that though the pebbles are very dense, they can float in deep ebb-flow systems. We recommend top watering systems for Hydro. For ebb/flood systems we recommend using our Gold Label Hydrocorn clay pebbles. As the pebbles are round and have a very even shape they leave a lot of space for air in the root system. The closed even pebble makes it hard for the roots to attach, enabling easy cleaning and re-use of your substrate.

Directions for use to get the best results with Hydro Round Substrate 

Rinse and soak Hydro before you use it the first time. Measure the pH value, as new pebbles have high pH bring it down with pH- to an appropriate stable pH.

The recommended pH range is 5.5- 6.5, however, this depends on your nutrients.

After each grow (or even during) flush with enzymes to clean.

Always work very clean to prevent infections when using inert hydroponic substrate.

If you had any disease or infection, disinfect the substrate with a hydrogen peroxide solution. We recommend disinfecting the substrate at least once a year.

When reusing the substrate, leave the small root material in it. A second grow on the same substrate can give you a better result.

We recommend using Gold Label Hydro nutrients on Hydrocorn. These professional hydroponic nutrients quality ingredients facilitate the plant's nutritional uptake process. 

If you recycle your nutrients make sure that the pH and EC level stay within range. Work very clean to prevent the spread of pathogens throughout your crop.

Clean your tank and replace your nutrient solution at least every week.
