Planting substrates

 
I have collected and used several substrates over the years ... but what gives me the best results?

With the help of fellow APSA and TASA members I hope to develop a testing protocol to evaluate these and other substrates.
The initial thinking is to do a single water column test using sunlight as the light source.
 
 
 This is the the plants I will be using .. Vallisneria sp. 'Mini Twister' it has proven to grow well in previous outside experiments with ADA aquasoil, PFP and silica.
Samples of the various substrates to be tested ...
 
 
 
 
 
  Keen to know how much of each substrate was used ...

See howmuch
