Welcome to my site!

My name is Dr. Daniel Fernandez. I have worked as a consultant for the past 10 years in the hydroponic industry, helping growers with nutrient formulations, crop management and automation.

Our services

I provide different types of services to suite your particular needs.

I understand that not everyone needs the same type of assistance and I have therefore designed three specific type of services depending on your needs .

• An hourly consultation service where you can ask any questions and get answers to help you solve problems (150 USD/hour).
• A service for the formulation of a specific hydroponic nutrient recipe for your particular needs coupled with guidance in preparing this formulation.
• An on-going consultation service where you will have me available to answer questions and help guide you through your nutrient needs as your crop or hydroponic project progresses.
