I know this is a s old . But howd it work out , Rubi ? What did you grow in it? I am considering it for sempervivums . The mix I currently use has been 75% pumice and 25% Coco Loco potting mix . I had some that didn't do too well due to the rains in summer this year. So I'm considering trying Pine bark in the mix as well. I am using my vacuum mulcher to make it the right size and it is a lot of work. I spent $90 on the motor. I probably would've been better off just blowing the money on bonsai jack pine bark fines. 🤣. But I figured I could use the leaf blower/mulcher. It's a tad awkward. And it is kinda heavy. I may return it and get a different one. I chose the Toro brand because it has a metal impeller.
