Good day y'all! I am from Canada and I am in prime time repot season and cant get my hands on any acadama, pumice or lava rock. I have heard that Safe T Sorb, sifted perlite, and bark or coffee grounds work well. Does anyone have any experience with this? Are there any other suggestions? I have mostly pines, junipers, and a few larch! Thanks in advance.

Which province? I am in NS. I ask because I am past re-potting season here.

T-sorb, perlite and bark mix is nigel saunders special canadian mix. Should work good in Canada.

sifted perlite, why not and composted bark would be good, there may be gravel for you, for the coffee grounds, don't know a nitrogen fertilizer
