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.
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.
