Hydro Roots does not contain any organic elements. Therefore it’s perfectly suitable for growing in hydroponic systems. This also ensures that nutrient solutions are longer stable. 

Due to phosphorus root growth is promoted, root length is increased and root cell division as well as root cell enlargement are improved.

Boron increases the activity of enzymatic systems which results in better nutrient absorption.

We recommend using Hydro Roots with Hydro A+B, Green Sensation and Power Buds. But all additives from our UNIVERSAL line can be infinitely combined. You are free to mix and match to your heart’s content!

You want your plant to have enough roots at the beginning of the flowering phase, so that it can use its energy to produce flowers. Therefore, stop giving Hydro Roots after the third week of flowering.

The main difference is that Power Roots contains organic elements, therefore it is less suited for use in an irrigation system. We’ve developed Hydro Roots, which is strictly mineral, so it won’t cause any problems in your (circulated) irrigation system. In conclusion, Power Roots is better suited for hand feeding and Hydro Roots is better suited for system feeding. If you insist you can still use Power Roots in a system, but make sure to clean it regularly.
