@Grower13 @99PerCent . Aeration/drainage is your friend, but does it have to be perlite? I still use it, but I´ve been trying with other materials in my current run, rice hulls (regular and charred) and pumice, and probably will look to experiment with sand (although the weight concerns me). Perlite here is expensive and not readily avaibale, aside from a non-renewable resource and nasty to work with (that dust)-
