RAW Genetics sells clones directly to the public from https://secretselections.io/
Also, sometimes Rasta Jeff of IRIE Genetics also has clones, and those can be found at https://iriedirect.com/ .
Lastly, there’s always https://iwantclones.com/ which has an enormous selection.
Personally, I think RAW has the most consistent selection at a really good price. You 3 unrooted slips, sometimes 4, and I’ve never had a slip from them fail to root.
Jeff’s clones are harder to come by, but his prices are incredibly fair. Get them when he has them! Look for Lemon Jeffrey #1, I’ve grown it 2 runs in a row now.
