I am not an Aussie and I haven't ordered from said seedbank, but....12 days that isn't an exceptionally long time I don't think for an international package to get to you from the netherlands. It could take 2 weeks I just got my seeds today that i ordered from the netherlands (sannies seeds) on the same day you did. I have shipped stuff from the us to Australia and it took like 18 days, I think you guys just have slow customs inbound. Cant help with the MF ratio....what seeds did you order?
