My Blog
Through my blog – a top 50 hydroponics blog according to feedspot – I share my insights, research and experience in hydroponic culture. I strive to make this blog a reliable source of high quality, practical information for both commercial hydroponic growers and hobbyists alike. These are some of the blog’s most popular posts:
Welcome to my site!
My name is Dr. Daniel Fernandez, and I have been a consultant in the hydroponic industry since 2009. I specialize in nutrient formulations, crop management, and automation, providing tailored solutions to optimize growers’ results. I hold a bachelor’s degree in chemistry, as well as a master’s and Ph.D. in nanoscience and nanotechnology. With over 15 years of experience in nutrient solution chemistry and crop management, I am dedicated to helping you elevate your crop production to the next level.
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 (250 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.
Hydrobuddy - Open source software for Nutrient Formulations
This site hosts HydroBuddy – a software I programmed – which is the most popularly used open source calculator for the formulation of hydroponic nutrient solutions and fertilizers. This software has been helping hobby and commercial growers prepare their own fertilizer formulations from 2011 with more than 10 thousands downloads in its lifetime. There are also many peer reviewed academic publications that have used hydrobuddy. Feel free to use or modify this software for your nutrient preparation needs. It’s free and OpenSource!

Methods to Enhance Terpene Production
Introduction Terpenes are a large and diverse group of natural compounds that constitute the most abundant class of plant secondary metabolites. These volatile organic compounds play critical roles in plant defense against herbivores and pathogens, mediate plant-plant communication, and attract pollinators (1). Beyond their ecological functions, terpenoids have immense commercial value in pharmaceutical, food, cosmetic, […]
Exogenous Terpenes in Agriculture: Can External Application Improve Crop Performance?
Terpenes are among the most diverse and abundant secondary metabolites produced by plants. While these compounds are well known for their roles in plant defense and stress responses, recent research has explored whether applying terpenes externally to plants can provide practical benefits in commercial agriculture. This post examines the current scientific understanding of exogenous terpene […]
An Expanded View on Root Zone Temperature in Soilless and Hydroponic Systems
When we think about optimizing hydroponic systems, most growers focus on nutrient concentrations, pH levels, and lighting conditions. However, one of the most critical yet often overlooked factors that can dramatically impact plant performance is root zone temperature. Understanding the intricate relationship between temperature and root physiology can be the difference between a mediocre harvest […]
NIR Devices for Leaf Tissue Mineral Analysis
Traditional leaf tissue analysis can cost 50 to 150 USD per sample and take weeks to complete, forcing growers to make nutrient decisions based on outdated information. Near infrared (NIR) spectroscopy devices could theoretically change this reality by providing real time, on site mineral analysis of leaf tissues at a fraction of the cost and […]
