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!

Thiamin as a biostimulant in hydroponic and soilless systems
Vitamin B1 (thiamin) is one of those additives that has circulated through the hydroponic community for decades, but the science behind its actual effects on plant growth has remained somewhat murky for most growers. Many products marketed for hydroponic use contain thiamin as part of their formulation, yet few growers understand when and how pure […]
Exogenous Sugar Applications: A deeper look
The application of external sugars (sucrose, glucose, fructose) to adult plants has generated interest as a potential biostimulant strategy, with research revealing complex concentration-dependent effects that range from beneficial to detrimental. While some studies demonstrate legitimate applications in stress tolerance and disease resistance, the evidence for routine commercial use in hydroponic production systems remains unconvincing. […]
Ascorbic Acid as a Biostimulant: Alleviating Stress to Improve Yield and Quality in Hydroponic Systems
The search for sustainable biostimulants to enhance crop productivity has led researchers to investigate ascorbic acid (vitamin C) as a promising alternative to synthetic growth regulators. This natural antioxidant compound has shown remarkable potential in improving both yield and quality parameters in hydroponic and soilless cultivation systems. Understanding Ascorbic Acid as a Biostimulant Ascorbic acid […]
Organic Sulfur Foliar Sprays: Beyond Sulfate Salts for Hydroponic Crops
Most hydroponic growers think of sulfur supplementation strictly in terms of sulfate salts like magnesium sulfate or potassium sulfate. However, plants can also utilize reduced organic sulfur compounds that offer unique benefits beyond simple nutrient supplementation. These compounds, including thiourea, cysteine, glutathione, methionine, and S-methylmethionine, function as both sulfur sources and bioregulators that can improve […]
