I found an open source nutrient calculator: HydroBuddy
Blog from the developer, Dr. Daniel Fernandez, dating back to 2009: http://scienceinhydroponics.com/blog-archive
I’m just diving into the archive, but already I’m blown away by how legitimate and well researched his posts are. Wanted to share this out and spark discussions on all things nutrient related.
What questions do you have regarding hydroponic nutrients in theory and in practice?
What sources of organic nutrients or unrefined minerals do you find to be worthy of further investigation for use in indoor ag? Have you experimented with any?
Please share your experience managing your hydroponic nutrient solutions.
