Looking for info relating to seed germination? Whether you’re a novice or a complicated hashish grower, that is the information for you. High Times Cultivation Editor Nico Escondido solutions all your develop questions in his weekly Nico’s Nuggets column.
The Question: What Can You Tell Me About Seed Germination?
Hello, Mr. Nico!
I’ve a really technical query relating to seed germination, and I do know you’re simply the person to ask. I’ve a pal who holds a PhD in plant physiology, and he as soon as advised me that plant seeds might be “turned on and turned off,” such that they germinate at a fee of 100 %, or by no means.
For the lifetime of me, I can’t keep in mind how precisely he stated to do that, and I’ve misplaced contact with him in the meanwhile. I assumed I’d attempt my luck with you. Any information on this topic is appreciated! Thanks and sustain the great work my pal!

The Answer: Seed Germination Basics & Technical Theories
Thanks very a lot for writing in together with your wonderful query—and in your religion that we’d be capable of present some perception! I feel I’ve an concept of simply what your pal was speaking about when he described turning a seed “on and off” when it comes to germination.
Seed Germination Basics
To begin, we should first perceive that not all hashish seeds are viable for germination. Seed viability may be decided by the seed’s measurement, colour, moisture content material and age.
Young, immature seeds have very low charges of germination. These seeds are smaller and look very pale or white in shade.
Bigger, plump seeds which are darker brown in shade, with black tiger-like stripes are often good bets for greater germination charges. Seeds that have to be saved long-term (greater than six months) ought to be stored within the correct circumstances—in an hermetic container and in a dry, darkish and funky place.
To germinate seeds, there are fairly a number of straightforward propagation strategies.
Perhaps the only is to put the seeds between two moistened paper towels and lay them flat on a tray or plate. Keep the tray on prime of a heat equipment or delicate warmth mat, commonly moistening the paper towels. After a number of days, you will notice the basis ideas start to sprout.
If the seeds are being troublesome, you’ll be able to attempt floating the seeds in a glass of water for a day to assist soften them up. Some superior growers even use delicate cleaning soap options, razor blades and plant hormones to extend germination charges on previous or heirloom seeds.
Advanced Seed Germination
All of that being stated, there are some extra technical theories on plant seed germination which were examined. And whereas a few of these theories have been confirmed utilizing particular seed varieties, it isn’t recognized if these methods work on all plant species.
Perhaps probably the most well-known concept on turning seeds “on” and “off” for germination includes the flowering sign that triggers hormones in crops to fruit or flower. These similar alerts can be used to set off germination—or render seeds nonviable.
These “signals” are actually the absorption of particular mild frequencies.
In flowering crops, leaves of the plant decide up these frequencies, often in a selected order and period, which then triggers the discharge of hormones inside the plant that alters the plant’s organic features.
The Phytochrome Red (Pr) pigment in plant leaves that absorbs pink mild from the spectrum, in wavelengths between 660 – 760 nanometers (nm), is the primary sign caller. The pigment referred to as Phytochrome Far Red (Pfr), which absorbs purple mild at 760 – 800 nm, is the second sign caller.
Much in the identical means that these leaf pigments set off flowering, seeds—with only a single flash of sunshine at these frequencies—may also be turned “on” and “off” for germination.
When purple mild at 660 – 760 nm hits a seed after which is instantly adopted by a flash of purple mild at 760 – 800 nm hitting the identical seed, the seeds won’t germinate. Reverse this course of, and the seeds will germinate at a really excessive fee, if not in totality.
Trials with hashish seeds have indicated that this works for the hashish plant species; nevertheless, in sure subspecies of hashish (and strains containing numerous and hybridized genetics), the outcomes have been lower than sure.
Still, many savvy breeders and seed producers have included these methods into their practices with good success. Conversely, it has lengthy been suspected that Customs & Border Control businesses, in addition to different regulation enforcement businesses, have additionally practiced these methods on hashish seed shipments throughout worldwide borders, although that conspiracy concept appears a bit far fetched.
