if i have a mix thats supposed to be 1 part peat, 1 part perlite, 1 part sand how do i measure this out?
for example am i supposed to measure it by weight? so 1 pound of peat, 1 pound perlite, 1 pound sand
or am i supposed to measure it by "cupfuls" so like 1 cup of peat, 1 cup of perlite, 1 cup of sand
thanks for the help
