The study concludes with 84 people sampling the finished product....has parameters for the people to respond about taste,smell, color of the ash whatever the other one was...they combined all 4 as good bad etc. Lol
The parameters should have been seperated and respondants given their opinions separately for each given parameter. Taste, smell, high, color of ash. They just combine them all....this is what i hate about studies...its like create a wanted outcome and cook the "study" to get that desired outcome....why didnt they compare different substrates, fertilizers(synthetic vs. Organic), ph, temps, etc.
Id like to see a flush study based on ph...high ph 10. That will make everything unavailable to the plant cant take it up cant store it right? I could be wrong since i have a limited knowledge of chemistry....
