Wish I could help and give you a real true answer but I really am not sure I am still a beginning grower my self just starting out . Does seem like i have seen somewhere on ere before though that if the tail on the seed is a certain length they should make it but am not sure . I just got my order of seeds today but I cannot plant mine for a couple days because of this storm we have coming in so I am almost in the boat you are in trying to figure out the proper way to store mine until im ready to plant.
First of all... I would say that when you get your seed in you need to get it in the ground asap.
If you do have to store it in the fridge do your best to minimize that time.
Make sure it stays slightly moist but not wet. The seeds will start turning light whiteish color when they start to dry out. Add a few drops of water at that point and mix them up good. I check mine every day, and mix them when I do have to store in the fridge.
It is not unusual for some seed to \"tail\" where the seed coat is split and the tip of the root is starting to come out. But that should only be a small percent of what you have in a good batch of stratified seed. I have received seed in the past where something like 3-4% of it was tailing. You do have to be careful with them - if you break off that tail I don't think it would survive.
If you do have seed where the majority are tailing like that, I would get them in the ground asap, and be very gentle with covering them and getting them planted.
Appreciate that info TNhunter they just arrived a little while ago it took them a few days to get here three to be exact . I figured they would be dry so I unbagged them and put them in between two damp paper towels for a few minutes then let them get a little air so they weren't to wet and rebagged them and plan on planting them tomorrow and hope the storm doesn't wash them away . Also when you say if they turn a whiteish color they are to dry , you are talking about the outside shell right ? Because I bit one of my seed into and the inside is white . Idk thanks for the info though .
