how do you prepare rye berry substrate with out a pressure cooker?
sorry for the noob question =(
you cant steam don't get hot enough with out one
u cant. The only way to get started without the pressure cooker if BRF.
All grains require a PC.
You really need a PC to prepare grains. Grains harbour things that cant be killed by steam sterilisation.
Stick with the pf tek, and if your wanting to improve results, then spawn to bulk substrate which only has to be pasturised. Like coir and coffee.
