There' not even close to 60 strains available right now. Most the LPs with any product are only offering 4-5 strains each. The only LP right now with more than a handful is Peace Naturals and they seem to be always sold out of all but 2-3 strains at a time. Tweed looks they are starting to offer more too. I wonder if they realize there is like 500+ different medical strains with more being developed all the time. Offering 5 strains isn't going to cut it.
Bedrocan=5 strains
CanniMed=4 strains
Mettrum=4 strains (more coming soon!)
Tweed=10 strains (listed so far, they claim to be offering 25+ eventually)
Peace Naturals=15ish strains (website is down, couldn't get an accurate number)
That adds up to 38ish strains if each and every one of those is completely different.
