Tips & Tricks For Seed Germination

Looking for information regarding seed germination? Whether you’re a novice or an advanced cannabis grower, this is the guide for you. High Times Cultivation Editor Nico Escondido answers all of your grow questions in his weekly Nico’s Nuggets column.

The Question: What Can You Tell Me About Seed Germination?

I have a very technical question regarding seed germination, and I know you are just the man to ask. I have a friend who holds a PhD in plant physiology, and he once told me that plant seeds can be “turned on and turned off,” such that they germinate at a rate of 100 percent, or not at all.

For the life of me, I cannot remember how exactly he said to do this, and I have lost contact with him for the time being. I thought I might try my luck with you. Any info on this subject is appreciated! Thanks and keep up the good work my friend!

The Answer: Seed Germination Basics & Technical Theories

Thanks very much for writing in with your excellent question—and for your faith that we might be able to provide some insight! I think I have an idea of just what your friend was talking about when he described turning a seed “on and off” in terms of germination.

Seed Germination Basics

To start, we must first understand that not all cannabis seeds are viable for germination. Seed viability can be determined by the seed’s size, color, moisture content and age.

Young, immature seeds have very low rates of germination. These seeds are smaller and look very pale or white in color.

Bigger, plump seeds that are darker brown in color, with black tiger-like stripes are usually good bets for higher germination rates. Seeds that need to be stored long-term (more than six months) should be kept in the proper conditions—in an airtight container and in a dry, dark and cool place.

To germinate seeds, there are quite a few easy propagation methods.

Perhaps the simplest is to place the seeds between two moistened paper towels and lay them flat on a tray or plate. Keep the tray on top of a warm appliance or mild heat mat, regularly moistening the paper towels. After a few days, you will see the root tips begin to sprout.

If the seeds are being difficult, you can try floating the seeds in a glass of water for a day to help soften them up. Some advanced growers even use mild soap solutions, razor blades and plant hormones to increase germination rates on old or heirloom seeds.

Advanced Seed Germination

All of that being said, there are some more technical theories on plant seed germination that have been tested. And while some of these theories have been proven using specific seed varieties, it is not known if these techniques work on all plant species.

Perhaps the most well-known theory on turning seeds “on” and “off” for germination involves the flowering signal that triggers hormones in plants to fruit or flower. These same signals can also be used to trigger germination—or render seeds nonviable.

These “signals” are really the absorption of specific light frequencies.

In flowering plants, leaves of the plant pick up these frequencies, usually in a specific order and duration, which then triggers the release of hormones within the plant that alters the plant’s biological functions.

The Phytochrome Red (Pr) pigment in plant leaves that absorbs red light from the spectrum, in wavelengths between 660 – 760 nanometers (nm), is the first signal caller. The pigment called Phytochrome Far Red (Pfr), which absorbs red light at 760 – 800 nm, is the second signal caller.

Much in the same way that these leaf pigments trigger flowering, seeds—with just a single flash of light at these frequencies—can also be turned “on” and “off” for germination.

When red light at 660 – 760 nm hits a seed and then is immediately followed by a flash of red light at 760 – 800 nm hitting the same seed, the seeds will not germinate. Reverse this process, and the seeds will germinate at a very high rate, if not in totality.

Trials with cannabis seeds have indicated that this works for the cannabis plant species; however, in certain subspecies of cannabis (and strains containing diverse and hybridized genetics), the results were less than certain.

Still, many savvy breeders and seed producers have incorporated these techniques into their practices with good success. Conversely, it has long been suspected that Customs & Border Control agencies, as well as other law enforcement agencies, have also practiced these techniques on cannabis seed shipments across international borders, though that conspiracy theory seems a bit far fetched.

From growing a few plants, to producing a large cash crop harvest, there are a large number of Cannabis seeds Australia gardeners who produce outstanding Marijuana from high quality Cannabis seeds. You can also find feminized autoflowering seeds which provide the dual benefits of a quick harvest and no need to identify plant sexes. The ideal is to germinate at the beginning of may, so that the plant seizes the maximum growth rate and we can enjoy an optimum harvest in middle summer.
Cannabis ruderalis is also a non-THC potent strain, so when it is cross bred with high-THC-producing sativa or indica, it retains some of the ruderalis properties, and some of the sativa or indica properties, leading to a lesser THC content than a strictly non-ruderalis strain.
You want a fast growing short term plant that is Sativa dominant. Of course, people do not just have to buy cannabis seeds locally in the UK in 2018. The cannabis seeds and buds you buy today are either purebred indicas or sativas, or a combination of sativa and indica parent plants.
Good for planting above ground crops with inside seeds. Big growth real Vigor, a real unique sticky feel to buds, old school flavor, I like strains like this, a real weed. In the past, landrace strains that happened to be sativas were eschewed by gardeners for indicas and crosses that featured shorter flowering periods.
Ganja is sometimes employed in place of bhang in the preparation of these beverages. Most Indica strains are faster to mature than Sativa’s allowing for earlier harvests. Good yields are easy for beginners and more advanced growers alike. You can either purchase cannabis seeds on the internet or from a local source.
Normally, cannabis ruderalis is not grown for recreational use, as it’s low THC levels are on par with hemp, and it rarely grows over two feet in height. As they approach harvest, your plants must be closely monitored. Automatic feminized cannabis seeds are very popular for the fact that they stay small.
Because of its high levels of CBD, Cannabis indica has also been the more prized of the two species in the treatment of insomnia (CBD tends to promote feeling of sleepiness or drowsiness), pain relief, and in relieving anxiety because of its sedating effects (Wujastyk 2001).
This ‘feminizing’ is accomplished by triggering one female cannabis plant into producing rogue pollen to fertilize another budding female plant. The modern ‘autoflower’ plant rarely has a life of over 10 weeks, with a vast selection of the autoflowering varieties being ready to harvest from seed in a mere two months.
Remember that the price of a seed doesn’t necessarily correlate to the strain’s quality, and don’t break the bank on your first grow. These seeds should be about 50% male and female. Many an overeager grower has regretted flowering too early, while more cautious ones often wait longer than necessary before harvesting.
It is sturdy and hardy Indica-dominant marijuana plant, dressed in brilliant hues, that produces several rock-hard buds all over its side branches. Seeds are available, but growers can also obtain some clippings from a healthy plant to grow as a clone. Those growing cannabis know there are many cannabis strains to choose from.
It will also be observed that the number of those who had been convicted, in this group, is much larger in the case of ganja and charas users than in the case of bhang consumers. Not very wide, it produces large, dense buds covered in an ocean of resin crystals of very high medicinal value and from which emanates a very strong odour of sweet pineapple or sweet citrus fruit such as mandarin.
Select from the very best in Dutch auto flowering genetics. Auto flowering is one of the techniques used to speed up the harvest time of the marijuana plants. Plants started outdoors late in the season never get very big and never attract the least bit of attention when placed next to weed plants of similar or taller stature.

Premature seeds in my bud

Im wondering what problems i might be having with this Chemdawg from barneys farm (5 year old strain keep moms about a year before recycling them into new moms) recently noticed potency seems down and im seeing premature seeds through the bud and no hermi problems, wondering if my genetics could be diminishing or what could be causing this issue, thanks for the help.

Could be a few things. I guess to start out, was your grow space totally light-proofed? Light leaks can cause a plant to turn hermaphrodite. I’ve also heard that environmental stress can cause this as well. Did you have any males for any period of time during that grow? Unstable genetics can give an increased chance of a plant turning hermaphrodite. I’m not sure if the seed’s age would or wouldn’t impact that. I’ve seeds about 5 years old though and thus far none have produced seeds. Is the Chemdawg by chance the autoflowering version?

No it was a feminized seed pack grew them all out to select good phenos for a mom plant kept the mom alive through cloning new moms from the original and have done so for 5 years now, so now this mother plant has been recycled from a clone of itself 5 times now, not sprouting new seeds of chemdawg sorry if i was confusing with my question. I feel like the genetics may be degrading over time, i feel like it may be because of one of the cuts i took to be a mom was a bad cut, i don’t really know whats going on its potency hasnt been up to par and like i said i have premature undeveloped seeds inside throughout the bud recently in the last few grows of it, and no hermi problems like i said there are no hermies or male flowers at all, i havent had anything hermi or even spit a banana out what so ever, its not a hermi issue at least its not imo and i feel like maybe some type of stress with light could be an issue but its light tight in there, im wondering if maybe there are other enviro triggers or conditions that may make the plants more prone to seeding? Idk really stunted here and have tossed alot of ideas around with other growers and still drawing up a blank here
