“The environment selects, the organism adapts.” ~Theodosius Dobzhansky
The first "F1" seed I ever grew was an Aurora Indica by Nirvana, pictured here in 2013.
This is an example of the earlier F1-style hybrids that Nirvana and other breeders pioneered in the 2000s. The Aurora Indica F1 seeds produced incredible amounts of weed even on a tiny plant. These days, breeders have taken F1 breeding to the next level. Aurora Indica F1 seed grown out, from 2014.
The technique is borrowed from traditional agriculture. At the grocery store, many tomatoes, peppers, cucumbers, squash, broccoli, and cabbage are actually grown from "F1" hybrid seeds.
"F1" cannabis seeds claim... - "Hybrid vigor" - better overall growth
- Clone-like uniformity - know what to expect
- Strong germination - faster start
- Resistant to stress - less to worry about
- Excellent yields - more weed for you
Sounds amazing, but is it true?
Yes, F1 seeds actually can offer those benefits... when developed properly. But if F1 cannabis seeds are so great, why are they so rare? Here's why "F1" seeds are rare online- Hard to breed - A good F1 seed breeding program that lives up to the benefits takes multiple years.
- Difficult to maintain - F1 seeds come from a pair of clone lines that must be carried on indefinitely.
- Costs more
- F1 seeds require extra maintenance to produce on a commercial scale.

Herm seeds (the "poor man's feminized seeds")
|
|
Did you find seeds in your buds even though no male plants were around? "Hermie seeds" refer to seeds you find in your cannabis buds without the presence of male plants. You may wonder, "What happens if I grow these hermie seeds?" Can you grow seeds from a hermie cannabis plant? Yes, but there are pros and cons.
|
Here is what cannabis growers can expect when growing hermie cannabis seeds: Pros - Free Seeds - These are seeds you find in your buds. Cannabis seeds cost money, and getting free seeds without any effort is appealing.
- All-Female Plants - If both parents were female (at least mostly female), as is the case with
herm seeds, all resulting cannabis plants will be at least mostly female and grow buds. In a way, herm seeds are unplanned, naturally-formed "feminized" seeds.
Cons - More Likely to Herm - Unlike professionally feminized seeds (which are created with a
special chemical process), hermie seeds come with more uncertainty. Although the resulting plants may or may not show any signs of herming, unfortunately the chances are higher. That's because for each herm seed, herming is in its genetics.
With high-quality cannabis seeds, plants usually only herm under major stress like nutrient
deficiencies, light stress, heat stress, unusual light cycles, etc. With really great genetics, plants won't herm under any conditions. But a seed from a hermie parent is more likely to herm even in perfect conditions. The plant went through extreme stress, so it was no surprise to find seeds.

5 strains with strong germination and classic smells across the decades
|
|
Some seeds simply sprout better than others. These genetics can give you a head start due to above-average germination rates. Purple Haze - These Purple Haze seeds achieved a 99.3%
germination rate in a recent test. Grows well outdoors, and buds will delight growers who miss that "Thai" weed smell from the 60s.
|
Northern Lights #10 - Northern Lights has always been known for exceptional germination rates, but this #10 cut has particularly strong sprouts. A very short flowering stage gives a quick harvest, and buds capture that US West Coast 70s
smell.
Green Crack - Let's move forward a few decades, to when Snoop Dog popularized "kush" smell. Green Crack captures the smell and effects of that mid-2005 kush. This is the weed I grew up on, and Green Crack always has a place in my
heart.
Do-Si-Dos - Do-Si-Dos was first developed in 2016, and breeders have continued working with the lines due to the exceptional bud quality and resiliency. This version of Do-Si-Dos is easy to grow, with its sweet floral smell, chill vibes, and
beautiful purple-tinged buds.
Black Cat Kush - This is a brand new strain with chunky, dense buds. Most buds have at least a purple tinge but 1 out of 5 plants produce dark purple buds that look almost black after being dried, hence the
name.
Do you all like hearing about what strains capture smells and effects from the past? I'd love to cover some of the classics like Maui Wowie and White Widow. Hit reply and share a classic strain you miss. I will share where to get modern seed versions of the most popular strains next week!
