How to tell if a seed is dead? Here are some tricks

Sometimes hemp seeds do not germinate because they are lifeless. Here’s how to spot a dead hemp seed and avoid wasting time

In previous articles, we have repeatedly stressed how the quality of cannabis seeds can make all the difference in achieving a healthy and productive plantation.

Poor quality seeds can lead to weak and unprofitable plants or even to no germination at all.

RED CRITICAL

RAINBOWS

GORILLA GLUE

PSYCHO XXL AUTOMIX

This article will learn how to recognise quality hemp seeds (such as BSF seeds) and tell if a seed is dead and therefore totally useless.

Dead or bad hemp seed: here’s why quality is essential

In the field of hemp growing, some choose to buy ready-made seedlings, and those prefer to plant the marijuana seeds themselves so that they can monitor the growth of the plantation from the very beginning.

Of course, in order not to waste time, it is essential to make sure that you are dealing with quality seeds of the right genetics (such as auto-flowering seeds, feminised seeds, etc., which you can find for sale at SensorySeeds), but above all, they must be alive!

Yes, you got that right!

If the seeds are too old or have been stored incorrectly, they may have lost their ability to germinate, and so, even if you put your mind to it, the seedlings won’t grow.

In the next section, we will clarify the main signs that the seeds you have in your hands may be lifeless.

Dead seeds: how to recognise them?

Many novice cannabis growers are tempted to buy low-quality marijuana seeds because they are sold cheaply.

Up to this point, it all seems quite normal. However, in such cases, the problem is that the seedlings often do not grow, and it isn’t easy to understand the cause.

Many people wonder what they might have done wrong and try to figure out what to do if the seeds do not germinate.

Of course, sometimes you make mistakes, but you have to check whether the seeds you have bought are still alive in other cases.

Knowing how to distinguish high-quality seeds from bad ones is very important to avoid wasting time and money.

Let’s start with the appearance.

Good quality seeds usually have a kind of waxy layer that shines when exposed to light. As a result, their colour can vary from brown to grey or black, with some speckling.

If you are dealing with white or light green cannabis seeds, they are immature and unable to germinate.

Seeds that appear ‘dried out’, have cracks or dents are of poor quality.

You can also tell by touch whether the seeds are good or not.

If you hold a hemp seed between your index finger and thumb and apply pressure, some seeds crumble, while others do not at all. The quality ones and the ones most likely to be alive are, of course, the latter.

A test is considered almost foolproof to see if hemp seeds can germinate: water immersion.

If by putting them in a glass with warm water they float, then it means they are dead or rotten; whereas if they go down, they are of good quality.

Of course, all these tricks apply to seeds of all genetics and types.

If we have intrigued you, you too can try floating feminised seeds, fast seeds or auto-flowering seeds from your collection (but remember that growing cannabis is not allowed in the UK).

Concerning the flotation test, however, we would also like to point out that it should only be carried out during the hours before sowing and that the seeds must be removed from the water within 24 hours. Otherwise, they will be irreparably damaged.

Live seeds which do not germinate: what is the cause?

If also thanks to the advice given above, we know that our seeds are alive but still do not germinate, there is probably another cause.

Let’s see what the main ones might be.

  • Soil which is too cold
  • Sometimes it is the temperature of the soil that is too cold that prevents marijuana seeds from germinating. If you keep the soil warm enough, you will see faster germination.
  • Incorrect choice of substrate
  • It is usually recommended to use a relatively friable and light substrate when sowing cannabis. If the seedlings do not germinate, the root growth may be prevented by too loamy and difficult to penetrate.
  • Sowing too deep
  • Cannabis seeds, being relatively small, should be planted close to the surface of the soil. Otherwise, the sprouts will not be able to emerge.
  • Insufficient irrigation
  • Sometimes cannabis seeds fail to germinate because they are not watered enough.
  • It is essential to keep the soil well moist, as this is the only way for the seeds to swell and germinate.

To conclude

As we have seen, you can use a few tricks to find out if your cannabis seeds are dead or not.

Unfortunately, even if the seeds appear to be alive and of good quality, they may have genetic defects. That is why the best choice is always to buy quality fast flowering seeds (such as BSF seeds) at the outset.

After this in-depth analysis and always remembering that cultivating and consuming cannabis is forbidden in the UK, we invite you to consult the seed proposals in our SensorySeeds.com store.

The Good Germin’: How To Germinate Old Weed Seeds And Bring Them Back To Life

Before there were marijuana clones and mother plants, there were marijuana seeds, the foundation of the cannabis industry. And here’s some big news for you: The price of quality marijuana seeds is going up while availability is going down.

If you were waiting to buy seeds of the famous, scintillating heritage or landrace marijuana strains we’ve been featuring, now’s the time. I’ve been tracking seed prices of quality strains sold by reliable cannabis seed resellers, and I’ve found that in the past year, prices have gone up an average of 30 percent.

Now, let’s talk about the challenge of germinating old, stale, or otherwise defective marijuana seeds.

No matter if you get your marijuana seeds from seeded buds (sometimes called bag seed), from seed resellers, from friends, or from dispensaries, seeds from different strains can show substantial variation in size and minor variation in shape. What you should be concerned about are seeds that don’t look like the seeds in the main photo accompanying this article.

Properly bred, dark-colored and patterned marijuana seeds like the ones in the above photo are seeds that by far possess the highest germination rate and produce plants with the most vitality and performance.

But if your cannabis seeds are pale, green, gray, shrunken, split, dried out, misshapen, poorly marked, or possess a hazy sheen (kind of like old wax that dried on a car before it could be buffed out), then those are defective cannabis seeds. Take a look at the below photo, which shows defective cannabis seeds that are far less likely to germinate.

Green, split seeds and seeds that aren’t properly shaped (mature cannabis seeds should look like miniature footballs) are immature seeds that didn’t fully ripen before the buds they were forming in were harvested. These seeds are a waste of your time.

Seed defects develop if your seeds have been stored improperly, or if the seeds are more than 4–5 years old. Also, if you get cannabis seeds from the less-reputable resellers, you might receive old or otherwise defective seeds. I’ve seen growers who eagerly awaited their seed order, only to be disappointed when they tore into seed packs to discover easily identifiable duds.

In many cases, the disreputable seed seller won’t refund the order or send a replacement order, and the would-be grower is left with a mixture of acceptable-looking seeds and defective ones.

Seeds that are grayish and sheeny are old seeds, and likely desiccated. Old seeds sometimes split or crack. If seeds of any shape are pale, light brown, gray, split, or cracked, they’re defective. But you may be able to salvage some of them so they grow out into plants that yield buds.

Tried And Tested Methods For Getting Old Seeds To Germinate. But Do These Methods Work?

Growers offer many tactics for germinating old seeds, and I’ve tried all their suggestions. I want to emphasize from the outset, if cannabis seeds are grossly immature, they’re unlikely to ever germinate, and it’s not worth trying to. For that reason, the following germination suggestions are for seeds that were allowed to mature and ripen fully before they were harvested.

Method 1: One of the most generic suggestions for germinating old, stale seeds is to soak them in reverse osmosis water pH adjusted to 6.1 for 24–48 hours, before placing the seeds into a rockwool cube, rapid rooter, peat pot or other germination media.

Result: I’ve seen no benefit from this suggestion.

Method 2: This one is rather extreme and time consuming. It involves scraping off the outer layer of the seed, sometimes including the shell itself, exposing the embryo and cotyledon, which are usually white, gray-white or greenish-white.

You then place the unshelled seed material into your regular germination media. Obviously, this is a severe tactic, and you shouldn’t expect it to work. But if the alternative is to not germinate the seeds at all, it’s worth a try anyway. If it doesn’t work, you’ve lost nothing. If it works, you’re a winner.

Result: It worked for me about 15 percent of the time I tried it on old seeds.

Method 3: Another radical tactic is to manually split one side of the seed shell, narrowly exposing the embryo and other internal material that is usually protected by the hard outer shell. The split seed is immediately placed in the usual germination media.

Result: My success rate for this tactic has also been about 15 percent.

Method 4: Over the years, I’ve seen companies offer “old seed soak kits” that allegedly contain special materials that stimulate old seeds to germinate. I contacted those companies and asked for third-party test data and ingredients information so I could ascertain if its products have any validity. Strange that the customer service reps refuse to provide information beyond vague, meaningless verbiage such as, “Our product contains bio-catalysts.”

They also refused to provide product samples. I have to tell you, if a hydroponics manufacturer or seeds producer isn’t confident enough in their products to provide samples for testing, this is an indication that their products are no good.

Result: Grower friends of mine bought several brands of “old seed soak” products and found them to be no more efficacious than soaking old seeds in pH-balanced reverse osmosis water, or just putting unsoaked old seeds into germination media.

If “seed soaker” products contain anything useful at all, it would likely be gibberellic acid, which has been used to treat marijuana seeds to induce germination, vitality and female gender.

Method 5: I’ve done experiments with stale, old seeds using a gibberellic acid pre-soak (i.e., adding gibberellic acid to get the soak solution to 100–150 parts per million), pH adjusted to 6.1, versus reverse osmosis water at pH 6.1.

Result: I had a marginally better germination rate from the gibberellic-treated seeds.

There are other experiments you can conduct if you have old seeds and you want to see if there’s any hope for them. Experiment with using seedling heat mats at a slightly higher temperature than for fresh marijuana seeds. Another tactic is to place the seeds less deep in germination media than you normally would, at about 1/4 inch (normal depth is about 1/2 inch).

You can try placing a T5 high-output fluorescent lamp over them even before they germinate, as if the light can coax them back from the dead like Jesus did with Lazarus.

Of all these methods, one thing’s for sure: Always use proper germination techniques, materials and procedures, regardless of the condition of your marijuana seeds.

Old Colombian Gold: After Germination, More Challenges

If old, stale seeds germinate at all, it usually happens several days after fresh seeds germinate. Expect fresh seeds to sprout 1–5 days after you start trying to generate them. But I’ve seen old, stale seeds that germinated after 13 days.

Even if you manage to coax defective seeds to germinate, you still have some challenges. Here’s an example of what I mean…

I had rare seeds given to me back in 2011. They were allegedly pure Colombian Gold genetics sourced from a lid of partially seeded buds in the early 1980s. Proper storage for cannabis seeds is in an airtight container in the non-freezer part of a refrigerator, and that’s where these had been since they were sourced.

The person who gave me the seeds said the last time he’d grown them was 2003. He had a 50 percent germination rate, but the strain was too difficult to grow outdoors where he lived due to climate conditions and because his locale’s high latitude is the wrong growing condition for a tropical sativa like Colombian Gold. After that failure, he put the remaining seeds back in the refrigerator and forgot about them.

I didn’t expect much from those old seeds. They were so tiny, about the size of a pinhead, and were pale gray, with that sad, dull sheen that characterizes old or dead cannabis seeds.

Still, Colombian Gold is a valuable strain and I had an indoor grow room I could easily control to give that rare heritage strain the environment it needed in which to thrive. I soaked the seeds for 24 hours in reverse osmosis water to which I’d added a very tiny amount of the vitamin B booster B-52, which is useful whenever you have stressed plants or seeds.

I planted 17 seeds about 1/4-inch deep in rockwool cubes and kept the seedling heat mat at 80°F. After five days, I saw no germination. But at day seven, one seedling popped its head above the cube, and by day 11 I had five Colombian Gold seedlings.

Five seedlings aren’t enough for a grow op, so I started fresh seeds of other sativa strains. Those seeds germinated in three days or fewer.

I measured performance of the Colombian Gold seedlings against the seedlings grown from fresh seeds. Two of the Colombian Gold seedlings were mutants — their early set of true leaves failed to develop properly, and the next sets showed the same mutation, so I terminated them.

One thing to expect from stale, old seeds: They often show mutations. Also, expect weak growth and dullness. The three remaining Colombian Gold seedlings popped their heads above the rockwool, developed 2–4 sets of normal leaves, then stalled.

As the seedlings from other strains gained height every day and their leaves grew larger, the Colombian Gold seedlings went into suspended animation. I tried giving them varying doses of light intensity and wavelength. I kept them on the seedling heat mat. After three weeks, when seedlings from fresh seeds were nearing a foot or more in height, only one Colombian Gold seedling had grown taller, but it was still several inches behind the fresh-seed seedlings.

I ended up keeping only one Colombian Gold female. It never had the vigor, root development, bud development, stalk sturdiness or harvest weight that fresh seeds of the same strain would have yielded.

This poor little female clearly lacked vitality from its earliest days, and generally plants grown from old seeds often have to be babied along. This means giving them extra doses of vitamin B, less light intensity than the other plants in the garden, more staking and other structural supports, more carbohydrates (like Bud Candy and Microbial Munch), and more potassium silicate (like Rhino Skin) to strengthen their weak stalks.

These compromised plants lack vigor, and may take longer to mature and develop in both grow phase and bloom phase. They might have hermaphroditic tendencies, weak stalks, insufficient root development, or be especially prone to spider mites, gray mold, pythium root rot and other attackers.

I had to baby that Colombian Gold, but she rewarded me with authentic sativa buds that were long, thin, and a beautiful golden color. The high was stellar and very 1970s-ish.

If the plant had been stronger and more vital, I would have kept it as a mother plant or waited until I had suitable male pollen before breeding her. But she was an experiment, the seed she came from had lain dormant for too long, so her adult life was feeble. I was lucky to get any nice buds from her at all.

Mind you, old and stale seeds aren’t always a dead end. I’ve had nine-year-old marijuana seeds that sprouted within seven days and grew out to be lovely, strong, heavyweight marijuana plants. And those seeds had been stored in a plastic bag inside a sock in a drawer in someone’s bedroom!

The message here is that if you have defective seeds that are immature, don’t waste time on them. But if you have old seeds, there’s little harm in trying the tactics I’ve discussed to see if you can grow out any of them. You might be able to get rare genetic treasure from old marijuana seeds, which makes it worth the effort to try to germinate them.
