I am using a 35/65 perlite/FFoF mix for my girls right now but my soil has gotten really hard and my water retention is TERRIBLE! It used to be fine, I would pour about .5L into my 2 gal pot and get absolutely no runoff. Now, when I pour .5L in, it seems to just shoot right to the bottom and drain out, I'm getting about 30% runoff (which I know is optimal, but I prefer to have no runoff due to my cramped grow conditions.)
Is there anything I can do to improve the water retention of my soil, or from now on am I going to have to water more frequently?
