PlantFood is a program used in hydroponics, It is used to calculate the amount of salts needed to get a desired PPM ratio.

This is the one of the first programs I have ever written! I wrote it around 1991, and it was originally written in Turbo Pascal, I have since ported it to Free Pascal

It is a console application, so its not using an exactly modern interface.

The reason I wrote the program was, at the time my Dad was very much into hydroponics and kept asking me to calculate how much of this or that he needed to mix. Necessity it the mother of invention and the rest is history.

I took Pascal at school, loved the Borland IDE at the time, I remember being quite excited about Turbo Pascal, or anything PC'ish for that matter.

This is one of those sentimental things for me, anyway if you could use/improve on it go ahead!

• Considers the N, P, K, Ca and Mg ratios for various plants.
• Calculate using your own custom ratios.
• Add new salts/fertilisers.
• Compiles under Linux/Windows
• Very small footprint.
