I just did a quick forum search, they probably are great people but there are a few threads here which said their genetics weren't so good and the gorilla glue imparticular was mentioned. Just a heads up.
I'm looking at S1's as well, probably gonna be a pheno hunt though, maybe an S2 would be a better choice if done right. Yup to bad clones are hard to get here, perhaps it'll get better next year but doubt it, I'm thinking "careful what you wish for" is gonna be the thought of the day when legalization happens.
Edit: just an FYI but there are clones available for sale at a few dispensaries in Eastern Ontario, Deseronto comes to mind lol.
