Thanks for the heads up!
How disappointing for you though! Did you have a backup method for identifying the seedlings or are they mostly unknown crosses now?
I've been considering different label options lately. For years I've used the the Avery White Permanent Durable Labels (the ones that say "Durable I.D Laser Labels" on the sheets) and they last really well. I love them, but up here in Canada I can't find the size I need, so I'm considering trying Uline's Weather Resistant Laser Labels (model no. S-16643) next time. They advertise that they're recommended for vinyl drums, outside inventory or nursery flower pots and are made with tear-resistent polyester to repel moisture--so they better hold up! (If anyone has tried them I'd love to hear how they worked out for you.)
