3 TIPS FOR NEW GROWERS

Pick a growing style that works for you

The very first step new growers will take when beginning to grow autoflowers is choosing a growing style. There are many ways to successfully grow, and each system will have its own unique benefits and limitations. Prior to germinating their first seeds, new growers will want to choose whether they will be growing indoors, outdoors, or under mixed lighting. They will need to also select a growing medium, as well as a watering style and nutrient regiment. To ensure a successful grow, it is imperative that new growers research and select a system that works best within their own unique parameters and preferences.

Source genetics that both meet your preferences and work best in your chosen system

When selecting genetics, new growers will want to source varietals that first and foremost meet their individual preferences. This may include strain lineage, flavor profile, effect, THC%, etc… However it’s also important to select varietals that work best within a chosen system. For example, certain strains will grow smaller, while others grow larger. Some are better for indoor growing while others work well for outdoor growing. Some strains are heavier feeders while others are lighter feeders. Once a system is chosen, new growers can select genetics that work best within them to strengthen the odds of having a successful first run.

Familiarize yourself with how to dial in environmental and lighting needs for your plants.

Autoflowers grow best within an optimal environmental range. The three pillars of this include temperature, humidity, and light. To dial in temperature and humidity, growers should familiarize themselves with Vapor Pressure Deficit (VPD). To understand how much light a plant will need within a day, growers should familiarize themselves with Daily Light Integral (DLI). Lastly, proper airflow is imperative to regulating the environment of a garden. It prevents unfavorable microclimates by moving new air in and taking old air out.

MEPHISTO GENETICS x AMERICAN AUTOFLOWER CUP

January 2026 marked the 4th annual American Autoflower Cup, and this year our team made it out to Los Angeles, CA in full force! To celebrate our community, the Mephisto Genetics team hosted a meet & greet at The Woods in West Hollywood. Here, the MG team were able to connect with close members of our community. This included a few of our esteemed testers. Being able to connect face to face with our testers in an environment where we could open jars, calibrate our palates to one another, and intelligibly discuss flavor profiles and derive aromatic notes was priceless. The ambiance inside of The Woods garden lounge made the perfect backdrop to this epic meetup of growers and testers.

Subcool Seeds: Notes From the Breeder

Posted on January 12, 2026January 15, 2026 by Crystal Hinners

Subcool shares 3 tips for new growers, their favorite breeding project & a story!

BREEDER OF THE WEEK NASC JOURNAL FEATURE

BREEDER INTRO:

Subcool Seeds is dedicated to continuing Subcool’s legacy, bringing his legendary strains to a new generation of growers.

3 TIPS FOR NEW GROWERS:

1. Start Simple & Learn the Plant

New growers often try to do too much too fast. Pick a solid medium, a proven feeding plan, and give the plant time to show you what it needs. Healthy cannabis communicates clearly — leaf color, posture, and growth rate will tell you far more than any chart ever will.

“Strong roots and steady growth matter more than chasing perfection.”

2. Don’t Overlove Your Plants

Overwatering, overfeeding, and constant adjustments are some of the most common beginner mistakes. Cannabis prefers consistency. Let the medium dry properly between waterings, feed lightly, and avoid changing multiple variables at once.

“Less intervention usually leads to better results.”

3. Genetics Matter — Choose Wisely

Starting with quality genetics sets the foundation for success. Stable, well-worked lines are more forgiving, express better traits, and help new growers learn without unnecessary frustration. A great grow starts long before the seed ever hits the soil.

“Good genetics won’t fix every mistake, but they’ll forgive many of them.”

FAVORITE BREEDING PROJECT

That’s a tough one for us because the honest answer is we don’t really have a single favorite.

Right now, our focus is on preserving and continuing the iconic cultivars Subcool spent his career creating and championing. Each project carries its own history, personality, and purpose. Some are about flavor, some about structure, some about balance and some are simply about keeping something special from being lost to time.

At the same time, we’re thoughtfully bringing these genetics from 2012, into 2025, and beyond. Sub’s work was truly ahead of its time, so our goal isn’t to reinvent it; it’s to let it keep speaking in today’s market. That means carefully selecting for louder terpene expression, improved resin production, and extract-friendly traits, while maintaining the character, soul, and integrity that made these strains iconic in the first place.

If there’s a “favorite,” it’s the process itself: honoring the original work, selecting with intention, and ensuring these genetics remain available, true, and accessible for future growers. Every preservation project is a reminder that great genetics don’t just happen; they’re built, protected, and passed forward.

Sub always said the plants would tell you what mattered and we listen. Our favorite projects are the ones that protect his legacy: preserving the cultivars he believed in, refining them with care, and carrying them forward without losing what made them special.

BREEDER OUTRO: A STORY, TO CLOSE

It’s honestly impossible to narrow it down to one story. Some of our favorite moments weren’t about a single smoke sesh, but about the rooms we were lucky enough to be in. We’ve shared joints, laughs, and long conversations with some true legends of the plant; Subcool, Kyle Kushman, Mr. Soul, OG Raskal, Ross (one of the creators of GG4), and many others who helped shape modern cannabis. What stands out most isn’t just who was there, but the energy: growers swapping stories, debating terps, laughing about failures, and passing knowledge the same way it always has; one bowl at a time. Those moments remind us that cannabis has always been about community, curiosity, and respect for the plant and the people who came before us. That spirit is something we try to carry into our garden every single day.

It’s about giving people a growing experience that they’ll take pride in. There is so much noise in this industry, and while we may not be the loudest in the room, we certainly mean what we say. The genetics that you’ll find here have been rigorously tested. They are on the menu because we love them, and nothing less. We have unique access to some of the best genetics in the world, and relationships with the breeders who’ve created them, and we want to pay homage to all of their hard work, while also striving to raise the bar and to create something new, something inspiring, and something you can trust.

bad apple cannabis seeds by dirty bird genetics

Bad Apple (Original Volume 2 Release)

Beth's Picks:

Pine Tree Kush:

(Grape Jelly* x Platinum Kush Breath Remix *Jelly Breath x Chocolate Pie)

I have an affinity for this plant. Ben says that when I look at it, I get this shit eating grin on my face, and I know he isn’t wrong. The buds are so dense. SO dense. She’s all calyx and they stack in this unique, knuckly way. She’s a bit of a stretcher with semi-long internodal spacing, but the gorgeous, boutique flowers she amasses are actually respectably sized unlike many of her ilk, and they’re some of the best quality flowers I’ve ever seen. To top it all off, her terpene profile is this striking mash up of pine, lemon pinesol and grape. It’s super complex and one of my favorite terp profiles ever.

Roadside Haze:

Sour Lime Haze x Skunch

The Roadside Haze was one of our first that I felt nailed that perfect trifecta of yield/morphology, quality, and terpene profile we are looking for when we breed. The quality and potency of this strain is incredible considering how well it yields and how vigorously it grows. She’s incredibly sturdy and an all-around powerhouse.

Sour Moose:

Sour Lime Haze #5 x Moose & Lobsta #11 F1

It was so darn hard to choose a winning pheno out of this run. From veg on, this cultivar stood out in a serious way to the whole team. Her stalks were crazy thick, her leaves were super large, and her health and vigor was super striking. She was one of the most gorgeous powerhouses we’d ever tested. And that didn’t stop with veg. Every single one of her progeny were keepers in their own right, and her homogeneity was notable for an f1 cross. I think the potential in these genetics is off the charts and we are really excited to continuing breeding with this line.

Siobhann's Picks:

Cold Queso:

Dam-a-lam* x Skunch *(Dolato x Chocolate Pie)

Beautiful plant. Super terpy and frosty. Extremely smooth smoke - mellow high. Easy to grow - great for low ceiling grows.

Cold Queso Tester by Dirty Bird Genetics

Bad Apple:

The Brunch “Lover’s Cut” x Dirty Mimosa

A Brunch and Dirty Mimosa mashup with terps that come out atrociously addictive. Moderate internodal spacing allows for good airflow without defoliating.

Dirty Mimosa Bx2:

Dirty Mimosa 'White Cap Cut' x Mimosa

Takes something great and makes it better. A powerful zippy sativa in 50 days, in half the space with twice the yield of a traditional sativa.

Sarah's Picks

Cold Queso:

Dam-a-lam* x Skunch *(Dolato x Chocolate Pie)

... because of the crazy terps.

Sour Moose:

Sour Lime Haze #5 x Moose & Lobsta #11 F1

Incredibly easy, very little maintenance with great yields and awesome results. Will not disappoint any grower.

Mezzaluna:

Total Eclipse x Skunch

She may need some love and attention as she puts on weight, but man what a gorgeous plant. Really dark people with beautiful contrasting soft orange with hunts of pink in the fan leaves. She looks AND smells great.

Devin's Picks:

Thousand Islands:

Thousand Oaks x Maui Wowie 2.0

Knockout power for the novice smoker. Unlimited power for the daily user. Incredible growth speed and overall strength.

Sex Melon 2:

Watermelon Slush x The Brunch "Lover’s Cut"

Majestic looking when vegged out, and a colorful beauty in flower. Taste’s fruity and is a perfect hybrid to smoke early and often.

Maui True Blood:

Hawaiian Dream x Royal Blood x Family Secret

The death star of cannabis. A tank of a plant and an unreal smoke.
The strain was originally bred by Sticky Finger Seeds.

Ben's Picks:

Sour Lime Haze

MMXX x Elmo’s Army (Moose and Lobstah x Super Silver Haze)

...is probably my absolute favorite strain we've made so far. It is a very vigorous grower with high yields, amazing trichome accumulation, and some of the most sour, citrus-lime terps of all our strains. It works exceptionally well as a seed mother and has proven itself as a great breeder with its ability to pass along a lot of great traits to several strains. Sour Lime Haze is also very easy to grow as she is not picky about nutrients in my experience and can handle many environments with ease.

Sex Melon

Watermelon Slush x The Brunch "Lover’s Cut"

... is probably my second favorite strain but it is a very close second. The vibrant purple calyxes contrasting with the rust orange stigmas during flower creates a visually stunning cultivar. Aesthetics aren't the only reason I love this strain. The terpene profile is probably the most pungent with its complex blend of fruit, melon, potpourri, and something a little floral. A good yielder with plenty of internodal spacing to create channels for air flow during its growth without being too stretched out. The Sex Melon has also proven itself as a great breeding mother by consistently producing high seed yields in all of the projects she's been involved in.

Thousand Islands

Thousand Oaks x Maui Wowie 2.0

... has proven itself as an amazing addition to our lines. The sheer stalk strength of this cultivar alone is impressive with thick lateral stalks growing towards the light source without any staking necessary even during late flower when the buds start testing the branch strength. The dank and almost umami/ savory food flavors and smells of this plant also make it a stand out in the garden. The Thousand Islands is another very high yielding seed producer with excellent pollen catching stigmas. Any breeding project she has been involved in has been a dream with no setbacks due to odd flowering time or non-viable stigmas.
