m0useanswered grow question a month ago its in the diary setup like AsNoriu said. When you enter it it has to be how growdiaries list the strain. or it work work. So start typing the breeder or its name and then click the one it is.
If the breeder is not listed or their strain is not it will show up as custom. You can email GD if its not their but they don't poplate new stuff to often.
