Will a Cracked Weed Seed Still Grow?

With marijuana becoming legalized in more and more states and countries, like Canada, it’s only natural to think about starting your own grow. If you’ve had some seeds laying around for a while, it might seem like a no-brainer to use them. Still, what if some of the seeds are old and cracked? Will a cracked weed seed still grow, or should you just buy some new seeds?

A cracked marijuana seed usually cannot germinate, preventing it from ever growing. It’s recommended that you take great care to protect any seeds you plan on planting. At the same time, there are some people who carefully crack them, without damaging them, for better germination.

If you’re interested in growing some of your own marijuana from seeds, but you’re not sure how to tell if they’re good, we’ve got you covered. Below we’ll review the signs that a marijuana seed is good, and even show you how you can test your seeds. Then we will go over how to keep your marijuana seeds good for longer so you can always be prepared for your next grow.

How to Tell if a Marijuana Seed is Good

If you’ve got a handful of seeds saved up, some of them might be good. Fortunately, there are some tell tale signs you can look for to tell you whether or not the seeds you have can still germinate.

  • Check the seed for surface level damage: The surface of a marijuana seed should be smooth and dark. There should be a thin, slightly glossy, coating that protects the seed. Also, if you notice any small holes or cracks in the surface it is a sign of irreparable damage.
  • Ensure the seed isn’t brittle or easily breakable: While it’s true that great care must be taken to ensure a seed remains usable, they shouldn’t be so fragile you can break them by gently squeezing them. If you press the seed between your fingers and it’s brittle, or it collapses, it was never going to germinate in the first place.
  • Look at the coloring: Healthy marijuana seeds are usually darker in color. If you have a lighter color seed it could be a sign that it’s old and will no longer germinate. If the light coloring comes in combination with a brittle shell it is definitely too far gone.

Ensure that the seed you want to plant is firm, with dark coloring and a waxy coat on the outside. If it matches all of these requirements it will most likely still work. To find out for sure you can move on to the step of germination.

Testing Your Weed Seeds in Water

If you want more certainty that your weed seeds are good, there is one test you can perform that requires nothing but a small glass of water and the seed itself. Just don’t do this until you’re ready to germinate the seed because the exposure to too much water can ruin it otherwise.

  • Fill a cup with warm distilled water. The size cup you use isn’t too important because marijuana seeds are small and will fit in just about anything you’ve got.
  • Simply place the seed into the glass of water and check to see if it sinks or floats. If it floats, then in all likelihood it’s no good. If it sinks on the other hand, it’s a sign that it’s ready to go, and you should start the germination process ASAP.

Keep this test in mind if you ever go to grow anything else, as it works with many other types of seeds as well. The reason good seeds sink is because they still have all of their components inside, increasing their gravity. Bad seeds on the otherhand are often hollow or contain air pockets, which give them their ability to sit on the water.

How Long Do Weed Seeds Take to Crack?

Another way of phrasing this question is, “how long do weed seeds actually last?” When they finally give they may crack, lose their color or even become brittle and more easily breakable.

If they are kept out at room temperature most marijuana seeds will only last a couple of months. However, if they are kept refrigerated, they can last anywhere from five to ten years.

How Can You Make a Marijuana Seed Last Longer?

To make a marijuana seed last longer, you must first understand what it is that causes them to go bad in the first place. Too much Oxygen, humidity, light and sudden environmental changes all contribute to marijuana seeds going bad quickly.

To make a marijuana seed last longer, you need to store them in a place that is cool and dark with a consistent temperature. If you have a solid container you can put them in, the fridge is the perfect place.

Some experts suggest that if you have an extra fridge–like one in the garage–you don’t use as often, you should keep your seeds there. This is because opening and closing the fridge door can lead to temperature fluctuations that can damage the seeds.

What Can You Do With Cracked Weed Seeds

So, let’s say you’ve looked at the seeds you have and most of them can no longer germinate. Is there anything else you can do with them so they aren’t a complete waste?

If you have a bunch of seeds that have gone bad you can crush them up and place them in the soil of any plant to provide nutrients. As they decompose their nutrients will pass through the soil and into the plant you are currently growing.

So, Will a Cracked Weed Seed Still Grow?

Cracked weed seeds rarely germinate properly. The only exception is when people crack them a little bit before germinating them. This is because cracks often indicate that the seed is older and that important interior components have taken damage and been exposed to too much oxygen.

That said, if you have a bunch of cracked seeds you shouldn’t just throw them out. Grinding them up and spreading them out in the soil of a plant you’re growing can work as a great fertilizer. So when you find a seed that will grow, you can still put the ones that won’t to good use.

Inside, we’ll review the signs that a marijuana seed is good, and even show you how you can test your seeds. Then we will go over how to keep your marijuana seeds good for longer so you can always be prepared for your next grow.

How Long does Germinating Cannabis Seed’s (Wet-Paper Towel Method) take?

Hello, Im very very new at growing. I have alway’s been interested in growing, but never really had the urge to try. I put 1 Pure Kush seed in a glass of water at Room Temp. 24 hours later the seed sank. I gave it one more FULL day in the glass and then i moved it to the wet paper towel method. It has been in the paper towel for about 4 days now and still no root or crack? I was just wondering if this means the seed is dead? or does it just need a little more time? Someone told me it takes around 2-3 days. TOTAL. And my seed has been germinating for about 6 days total. 2 in the water cup, 4 in the paper towel. Any thoughts?

Once it sank you should have taken it out. You likely “drowned” it.

I’ve had great success with the water method, 100%. Once it sinks I go directly to soil. 3 days later, sprout.

2-3 days is typical, they can take longer. I doubt you drowned the seed either, some people germ seeds just letting them sit in water, I know they can continue to grow after they pop submerged in water. Is the paper towl being kept fairly warm?

At first, i had the paper towel on a plate, and put a plastic bowl over it to keep in the mostiture. But I dont think it was staying very warm the first few days. Now I have the paper towel in a little black box and I put the box above my water heater and now the paper towel feels warm.

Each strain is different i have a few seeds that took 12 days i gave up on them thank god i checked on them 5 days after i gave up. I put my seeds in a plastic baggy sealed in a wet paper towel under my tv and almost have 100% with germination. After these seeds germinated and popped soil they took off. Hopefully it is a good seed you have there if you have anymore try them too but beware growing is very addicting i got addicted almost to like heroin addiction here with my growing i eat sleep love my plants and cannabis its horrible

yea dont give up man some seeds take longer. next time try putting the paper towel in a plastic baggie and then put that somewere war and dark. personall i use jiffy peat pellets. i had one out of a batch of 12 that didnt sprout recently and the best thing is you can put the pellet straight into the soil.

The might pop then if they were being kept cold. I have nothing but problems trying to germinate without heat. You also dont want your paper towel to be too wet. just damp no dripping water.

They need to be warm. My method is glass of water until sunk. Into paper towel damp, not dripping wet. Fold it twice and place into plastic bag. I set the bag ontop of my router, its a nice warm location that doesnt get too hot. Just be sure to FOLD the paper towel, the extra layers are protection from too much heat and also from the light if your router is in the light(which mine is). My last germination attempt was on 34 seeds, 17 widow, 17 blueberry. Had 100% germ on the seeds. They were non fem from BCSeedKing.

Just my 2 cents.

it can take 1 day up to 2 weeks. glass of water is fine it will not drown as there is o2 in the water after it sprouts a little tail (another day after it pops) remove it from the water as there will now be a slight risk of it drowning.

I have 4 Orange bud seeds and 1 seed I found in some purple.. they all sunk now I’m.waiting for them to sprout in paper towels. 1 has even gotten green not mildew but a wet flower green no sprouts in a apt so Where is the bed place for good heat.. in paper towel inside plastic bag in side a black plastic bag and inside a drawer. Been 6 days now.. should I just pop these in miracle grow?

I use the papertowel method. I don’t look at them until after 48 hours. I usually see most with small roots. 24 hours later and 95+%
will have a 1/2 inch root or bigger and ready to go into dirt. Remember to keep the soggy papertowels sealed air-tight, especially
after the 48 hour check.

I’m new to growing herb but not to gardening. I don’t use the shot glass method as I’ve had a 0% success rate but using the paper towel method i place the towel between 2 paper plates and set it on my cable box(warm and constant) 2 days later maybe all but 1 pops half inch tails. I was away for 3 days once and a few had shed their seed casing and had embryo leaves and grew into the towel, but I just cut around the root and planted the into my grow medium(paper towel is biodegradable) and they grew just fine.

green isn’t good.. . I sed to use paper towl on a plate on top of the TV, back when Tv’s where thick enough to set stuff on, heh, but I felt the evap from the plate cooled too much, so I switched to paper towels in a small (6 quart) sterlite with lid on, and set it behind computer tower so the exhuast fan blows on it. Watch TV on the computer now too, heh

I wouldn’t use the paper towel method. Your seeds will be alot better off if you germinate directly in soil. what I do is soak the seeds in plain water for 12 hours prior to planting to hydrate them, which will speed up germination. It’s also possible that you may have a batch of bad seeds. in general, good seeds will sink, bad seeds will float. Here it’s some resources on how germinate marijuana seeds:

I dont grow any of the good shit like any kids of kush or what in florida its all called dro but i mainly grow high grade mids cause I think its the cheapest and easiest way to grown weed other then just throwing them bitches in dirt and hope they grow. but anyway when I germinate my seeds I take a paper towel put two seeds on it fold it over pour water of it put it in a bag and that the seeds do their own thing when they start to sprout i give in about another day or two (or until the roots have grown at least an inch) then i put them in little starter pots and put them outside until the grow about a foot them in my closet with a fan and two led lamps (i only grow for personal use) it takes about about 4 months sometimes sooner before they are ready to harvest
