Thanks for your answer. What is your opinion on what I posted a bit earlier? The recipes of Heisenberg and Richyrich look very similar. They both did a lot of testing and are both experts in this field, but there is one thing that they seem not to agree on. In Richyrich' recipe you will find the instructions to add 1.25mL of Roots Excelurator per Gallon water. Heisenberg says to avoid Roots Excelurator, or at least be aware that it can trigger slime. What do you think?
