I use these cases which have alpha numerical slots.
I write the same alpha/numerical system on all the tubes and throw them all in a ziplock.
In Excel, I make a chart with the same alpa/numerical.
When saving pollen, I just grab whatever tubes out of the bag, have my chart on a clipboard and record pollen parent with the corresponding alpha numerical designation written on tubes and then put them in the correct slots. In the winter when there's 4 feet of snow you can transfer your handwritten data in Excel so it's readable. :0 I no longer grow seedlings but like to donate the seeds.
The cases and tubes are from Earthstar but just saw a note that he's going out of business.
