All the perlite just separates from the soil. Since adding the perlite did somehow make the drainage worse I decided to add the other 20 lb bag of this soil I had. So, we ended up with 40 lbs of this soil w/ an extra 8 cups of perlite added to it. It won't drain. It turns to mud. The particles are too fine.

Since I couldn't add any peat to it...because it's being tested against peat!...I opted to put stones/pebbles in the bottom of all the pots that were being planted w/ the PS. This seemed to help. I didn't use stones/pebbles with any of the other mediums. I also used the lone terra cotta pot that I only have one of for planting w/ PS, since it has larger drainage holes.

Here's a pic of the PS straight from the bag.
