Hi, My first post on this forum.
Leon a 67 year old retired Australian living in Davao Philippines and trying hydroponics for the first time.
Slowly putting an over engineered hydroponics set up together. Not easy here as not much available and what is is of really bad quality but that's part of the facts of life living here.
Was going to use Coconut husks, fibre etc as my grow medium as it's readily available here but have found a source of Charcoal which they use to grow Orchids. Looks good to my untrained eye and my question is has any one used or know of using Charcoal as a grow medium?
Maybe a 50-50 mix with the Coconut fibre would be OK?
First I want to try to grow some decent Tomatoes and Strawberries.
Started to build a flood and drain system, flooding from the bottom however realized the grow medium was light and could cause floating problems so I've modified my ideas and now going to use a flood type system from the top and draining from the bottom. Will have to work out the times and flow rates etc and that's part of the fun of having a hobby.
