About Hydrotops nutrients

Hydrotops nutrients have been making nutrients for the UK grower for quite a while. The nutrients have been created for UK water. They even go one step further and offer a service to formulate their nutrients for your own personal tap water. All we have to do is send them a sample of your tap water. As far as we know Hydrotops are the only company to do this.

With a very dedicated following by certain growers, most of them would say that once you have tried Hydrotops there's no going back!
