Hi all,
cheers Darrel
Yes it isn't true. You don't need the buffers. have a look at <"The soil substrate .....">I use the Alkaline Buffer to stop my pH from dropping below 6, which I believe would cause my nitrifying bacteria go dormant. The acid buffer is to stop my pH from being pushed up too high. Please correct me if I am wrong on the low pH/nitrifying bacteria thing
