seeds with cracked coats plant or pitch?
every year it seems, when i harvest seeds for next years crop we get a bunch of rain that causes some of my seeds to swell and crack the outer seed coat enclosing the bean. are these seeds still viable? i have always tossed them, but now am thinking if they will still grow, that would help out with some varieties i have limited seed stock.

If you have limited seed, it can’t hurt to save them. but I would recommend performing a germination test before you plant them. The broken seed coat – and the exposure to moisture – may seriously reduce their viability.
You are just across the Lake from me, so I get the same early Autumn rains – and inevitably, some damaged seed. Even if the seed proves to be damaged, don’t pitch them. Throw ’em in the bean pot. I’ve got several pounds of mixed beans in an ice cream bucket now, and will make a big pot of soup with them. Kind of an adventure, since I grow different beans every year. it never tastes (or looks) the same twice.
thanks for the reply zeedman.
i know germination test is the thing to do, just never done it for some reason, and i do like bean soup so waste not want not.
i’ll give it a go.
Should I use a metal roof?

Is there hope for this room?
I have a bean jar too that I toss any bean into for soup. If it is past it’s prime, I leave it for seed. . I also go ahead and pick them when dry and even if I’m not saving them for seed, I put them in my soup pot jar.

Cannabis Seed Cracking Without a Cracker Tool
If you crack weed seeds just before germination, it may help them sprout
Sometimes, marijuana seeds are too weak or too old to sprout quickly, so you need to use some techniques to help them germinate. In this post, I will describe just one method – cannabis seed cracking.
The idea is that cracking requires some energy from an embryo and not all of them are strong enough for that. If you do this job for them, you help your seeds save energy and germinate faster. Besides, the process of germination requires some water to penetrate the shell, and if the seeds are old or haven’t been stored properly, their shell can get too dry to let water inside. The downside to this method is that you can damage the embryo if you squeeze the seed too hard.
Cannabis Seed Cracker: Is It Really Necessary?
I’ve come across a forum thread where people discuss buying a special cannabis seed cracker tool, and even watched a video where a weed grower uses it for seed cracking. You may google this gadget and spend a couple of dozens of dollars on it, but in my opinion there’s nothing special about a seed cracker. It’s just a simple contraption to hold a seed in place and gently apply pressure on it until the shell gives way with an audible crack. The cracking is done one seed at a time.
The good news is that you can do the same with your teeth just as easily!
Just firmly hold the seed with your finger tips, with the ridge positioned vertically and the pointy end facing outward, and gently bite on it with your teeth until you hear it crack. Then use your favorite germination method.
Cracked vs Uncracked
In my little experiment, I used 4 seeds of my OG Kush Auto that I’ve created myself. For some reason or other (because these feminized seeds were made by self-pollination maybe?), these beans are not very quick, especially if the room temperature is low, like it is now – 65-68 °F (18-20 °C). Let’s see if cracking makes any difference.
I’ve just placed 4 pot seeds between wet cotton disks.
After 36 hours, 2/2 of the cracked seeds and 1/2 of the uncracked (the one on the left) have shown tap roots.
After 60 hours, the situation has changed in favor of unckracked seeds. A least, the one in the bottom-right corner seems to be the winner.
72 hours (3 days) have passed, and the last seed to crack is also the strongest. The seeds that were cracked have crooked and somehow yellowish tap roots.
What Has My Cracking Experiment Demonstrated?
It is true that when you crack your marijuana seeds before germinating them, they may show tap roots earlier. However, the first one out of the gate isn’t necessarily the winner. Out of four seeds that I germinated I would definetely choose the one that was the last to crack. So, if you have a good fresh batch of seeds, don’t risk damaging them by cracking their shells. If the seeds are too old or haven’t been stored properly and wouldn’t germinate in a regular way, cracking may help.
