To be honest most mpc's now are not exactly great
their very lightness thus easy to carry, is in itself a problem. so convenient to carry and so cheap they seem good value
I have taken to using john innes......the worst JI is better than mpc for me.....for seed sowing, cuttings and potting. Using half perlite and half JI for seed sowing; according to variety (agastaches, pelargoniums,,aeoniums) 80% perlite and JI for cuttings and JI for permanent planting.
used this way, composts don't dry out as quickly and the extra weight provides stability in the wind etc. I also discovered little or no weevil occupancy
