I have some dolomite lime ( if I remember right ). And for the purposes of the mix I was thinking to use up the perlite I formerly used for cloning in, and have been collecting in random containers.
I don’t have any calcium carbonate in powdered labeled form. But if I remember right- that’s what oyster shells are made of, and I have lots of those.
I believe that CalCarb is optional, but I understand both will buffer the peat. IDK if oyster shells will have the same effect as mined calcarb. When I buy it from CustomHydro, it's sold as Mississippi Lime, but I get lost in all of the products that is called Lime. The important factor that is sought though is the ability to buffer the acidic peat. I think Farside's ratio of perlite is in the range of 20% whereas I use in the range of 40%. It's my opinion that greater drainage will allow the roots to grow quicker due to being able to dry the soil out quicker, but that's just my theory.
