I'm putting together a spreadsheet of the various requirements to grow different vegetables in hydroponics, e.g.:

  • days to first harvest
  • pH range
  • EC (Electrical Conductivity) range
  • Light range
  • Temperature

I'm thinking that having something that people could collaboratively edit could be useful. For example, also stating the variety, nutrients, method or grow light that was used. That could lead to creating common “recipes” for specific types of crops. You could even have recipes that change during the growing the period, for example increasing night time temperatures and decreasing daytime temperatures for fruit production in pepper plants after they reach their mature height.

I’m publishing this as part of 100 Days To Offload. You can join in yourself by visiting
