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.
After 36 hours, 2/2 of the cracked seeds and 1/2 of the uncracked (the one on the left) have shown tap roots.
If you crack weed seeds just before germination, it may help them sprout
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.
I’ve come across a forum thread where people discuss buying a special cannabis seed cracker tool. I 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.
Just firmly hold the seed with your finger tips, with the ridge positioned vertically and the pointy end facing outward. Gently bite on it with your teeth until you hear it crack. Then use your favorite germination method.
lmao!! Thanks, that made my morning!
Also the towel has to be wet, I mean soaking wet, not dripping but soaking, you do not want a puddle but moister, it helps it soak through the shell and makes it easier for the tap to absorb.
The Coral Reefer
We all have our own plans and ways, I am gonna try a light scoring with a razor blade or scalp, not deep just a light score along either the sharp edge, or maybe a couple over the rounded top and bottom edged on some of these bags seed see if it helps take in some more water and crack. Seeds have some stored energy which is there to help a tap and base leaves develop. but if they use it all breaking the shell they cannot then push to set the tap and break the earth/soil/medium. NO BUENO. ( Learn this farming ** not bud btw real farming ** since I was a child so over 20 years. )
Right now i am messing with bag seeds cause I dont wanna fuck up my nice attitude seeds until i have a pretty solid system down.
whatever technech you use try not to damage the inside embrio of seed
Another method of making the outer shell more penetrable is scarification, and the most straightforward way to do this is to use sandpaper. Take a matchbox and line its inside with sandpaper, or roll a piece of sandpaper into a tube. Then, place the seeds inside and shake them for a minute.
The problem with these stimulators is that you never know the correct dosage. The information shared on marijuana forums is anecdotal, and legitimate studies have only been performed on other crops. So, if you decide to use any of these additives, do some research or ask other growers, and always err on the side of caution.
This procedure is similar to cracking because you’re forcefully opening the seed—not by applying pressure this time, but by using a sharp knife. Please consider this a last resort—suitable only when all else fails.
3. Crack Your Weed Seeds
Although prime cannabis seeds are typically younger, old weed seeds may still be viable! However, you have to go about germinating them differently, as time tends to harden these magic beans. Learn how to germinate your old cannabis seeds to achieve a bumper harvest.
Instead, take a glass of water and throw your seeds into it. Twelve hours will be enough for the shell to soften a little and the water to finally get inside and wake up the embryo. Don’t forget to check the seeds regularly. As soon as they crack and the taproot appears, you should take them out. Seeds are living organisms and they need oxygen. Leave them submerged for 24 hours or more, and they may drown.
That’s why it’s so important to store cannabis seeds in a dry place—so they don’t germinate prematurely, become mouldy, or rot.
Use a sharp knife to cut the whole length of the ridge, on both sides. Be sure not to cut too deep and damage the embryo.
