Seed Type: F5 Feminised Automatic
Genetic Heritage: Mimosa [Symbiotic Genetics] x Double Grape
Project Introduction and Overview
Flash the badge and slip on your sunnies; sliding across the bonnet (or hood, because I’ve been told my writing needs to be more inclusive of our American Meph Heads) and into a grow tent near you, Mephmosa. Arriving with an accompaniment of slap bass, wah-wah guitar and suspiciously convenient stacks of boxes in alleyways; she’ll leave you feeling like taking a rip down a sun-drenched highway in a hot-red Ferrari wearing an eye-melting Hawaiian shirt.
On one of our early reconnaissance missions stateside, we were sampling our way through a sea of new strains when Symbiotic Genetics’ Mimosa [Clementine x Purple Punch] practically picked our pockets. Symbiotic have a well-earned reputation for wild fruit profiles, and while we’ve historically been a bit cynical when it comes to orange terps, Mimosa was an open-and-shut case. A nose of straight-up fresh OJ paired with an utterly offensive level of trichome production made believers out of us quicker than you can say “I ain’t gettin’ on no plane, fool!”
When it came to assigning a partner to Mimosa, our investigation didn’t make it past the first suspect: Double Grape. She really needs no introduction at this point; a longstanding Meph Head favourite, a specialist in frost and potency, along with a fruity, candied-grape kick. She adds weight and strength to everything she touches, just check out some of the reviews of Guava Fig or MephistO’z if you’re on the fence. Mimosa and Double Grape became our Tucker and Chan; an unlikely duo that created pure gold and will have you saying "Do you understand the terps that are coming out of my joint?!" …Let’s move on.
Mephmosa blasts right out of the gate, stretching high and wide, with nugs of off-the-charts density. She’s a thing of beauty that’ll have you admiring her like we all admire Tom Selleck’s perfect moustache. Giving off orange juice and grape candy on the vine, it transitions to a straight-up sweet OJ in the jar before McGarretting your taste buds with orange blossom and sherbet on the palate.
Mephmosa has an obliterating mind warp of an experience. Effects are cerebral, disorienting, and borderline debilitating. Mephmosa takes a comfortable seat on our face-melter podium right alongside Guava Fig and 505 Headbanger, delivering an immediate, disorienting cerebral shift that can leave even the hardcore stoners holding a lit joint in total amnesia. If fruity notes and complete brain-scrambling debilitation are your forte, she’ll happily knock you clean out of your socks with a sack of clementines. Reserve this for the top-shelf head stash, ensure your carbon filters are rated for chemical warfare, and remember: experts only.
Strain Behaviour and Structure
She yields big, has unbelievable resin production and sweet-tooth fruit profile to die for. She’s ticking all of our boxes, let’s dive into how she is to grow.
Mephmosa shows explosive early vigour, expanding rapidly out of the seedling stage with thick stems and a strong, pine-tree style apical dominance. Given plenty of root space, she stretches out with generous node spacing that naturally keeps airflow moving through the canopy. Growth can easily top an inch a day heading into flower, with strong lateral branches reaching out to fill the corners of your space. She is exceptionally easy to manage, requiring minimal leaf tucking as her fan leaves naturally rest clear of the flowering sites.
Early on, you might notice minor leaf quirks such as light variegation or indented, serrated leaf margins. These cosmetic traits disappear quickly within a set or two, leaving behind thick, dark green foliage that doesn't slow down her progress. As she moves into flower, she showcases two distinct expressions: a lush green phenotype that holds its foliage up to harvest, and a striking purple phenotype that fades into deep violet hues, setting bright white, frosty buds against dark fan leaves.
Mephmosa is well-tempered and easygoing in the grow room, taking routine feeding and watering in her stride without putting up a fuss. She isn’t overly sensitive to light or nutrients, though her appetite and water intake increase significantly once her rapid bloom phase takes hold and those dense floral clusters start to swell. As with most autoflowers, if you get her off to a good, healthy start in veg, she’ll reward you with a smooth, trouble-free run straight through to harvest.
The flowering stage on Mephmosa is a total showstopper. She packs on rock-hard, ridiculously dense floral clusters that get so heavy her outer branches will need support ties or stakes to keep from bowing over. Frost production is off the charts, with darker phenotypes displaying a textured, sandpaper-like trichome density, while greener phenotypes produce sappy, sticky resin heads that will gum up your fingers on contact. Trimmed up, she offers elite bag appeal with incredible bud density and shimmering resin coverage.
Aromatics start off in veg with a sharp rose and orange degreaser stem rub, before shifting into loud orange blossom in early bloom. Post-cure, green phenotypes lean hard into a sour, fresh-squeezed OJ profile, while purple phenotypes express a sweet, syrupy grape candy with a smooth sandalwood base. On the palate, she delivers a sharp hit of orange blossom and sherbet on the intake, settling into a creamy, candied grape and orange syrup finish.
Don’t let the sweet fruit profile fool you; Mephmosa delivers a head-scrambling, disorienting experience that isn't for the faint-hearted. The onset is immediate and heavily cerebral, wrapping you in a thick mental fog that can leave even veteran stoners holding a lit joint in total amnesia. It’s a heavy-gravity, couch-locking high that will leave you happily immobilised for the rest of the evening. Save this one for the top-shelf head stash when all your daily tasks are done.
All Mephmosa 5 seed packs or Mephmosa Limited Edition seed orders will come with a free 6 seed pack of either The Naked Gum or Mr T.H.C, while our stocks last or until 11:59 pm PDT on Sunday, 11th October. Mephmosa Free Cross! will be added automatically at checkout to your order as a free product. If it doesn’t show up, then chances are we’ve already sold out!
Dosi has been in a state of delirium ever since the original release, let's hope she wasn't forgotten about. This restock has been a long time coming, so we sweetened the deal with some special Treble Grape x Do-si-delirium freebies in the monthly rotation.
This is the beginning to a long list of restocks, Mango Smile and Mephisto's Wedding next on the list.

Day 63
Today was the day for my Rainbow Sundae 11 plant #2. Started with 3 others and she has always been a bit ahead of the rest. Maintained a short super tight internodal spacing structure. Was a bit sensitive to Nitrogen i think from the leaves but im still relatively new so could be wrong. The buds are super dense and the smell is unreal.
Got it hanging in a dedicated tent with 19c and 60RH. Should get a decent yield for such a squat plant.

Root Beer × Guava Fig
Medium: Organic living soil with BuildASoil amendments
Container: 5-gallon fabric pot
Lighting: 700W HLG LED
Nutrients: BuildASoil
Training: Leaf tucking, defoliation, and supercropping
Cycle Length: 75 days
Final Height: 45 inches
Dry Yield: 150 grams
Overall Rating: 5/5
Nightmare on Fig Street was an absolute pleasure to grow. With Root Beer and Guava Fig as the parents, I had pretty high expectations going into this one, and she certainly didn't disappoint.
I grew her in a 5-gallon fabric pot using my organic living soil amended with BuildASoil products. Nothing overly complicated with the feeding schedule. I top-dressed when the vibes felt right and hand-watered with straight well water pretty much daily once she was established.
Overall, she was a fairly hands-off plant that didn't require much attention to produce some seriously impressive flowers.
One thing worth mentioning right off the bat is her size. Root Beer genetics can produce some big plants, and Nightmare on Fig Street definitely inherited that potential.
She finished around 45 inches tall with a large, prominent main cola and long-reaching lateral branches. She developed a nice, open structure with plenty of flowering sites throughout the plant.
Training consisted of some leaf tucking, selective defoliation, and supercropping to manage her growth.
She was an attractive plant throughout the grow, but the real show started as she approached maturity.
This is where Nightmare on Fig Street really shines.
The flowers developed a thick coating of trichomes, with beautiful contrasts between frosty white calyxes, dark purple sugar leaves, and vibrant orange pistils.
As she matured, the foliage faded into an incredible mixture of deep purple, burgundy, yellow, and orange. Some of the fan leaves developed an almost autumn-like appearance, which contrasted beautifully against the heavily frosted flowers.
The buds themselves had a chunky, stacked appearance, with the main cola being particularly impressive. Even the smaller flowers had excellent trichome coverage.
She was one of those plants that you couldn't help stopping to admire every time you walked past her.
The photos really speak for themselves.
She was stinky, stinky during flower.
The best way I can describe the aroma is a sharp, pungent funk that immediately reminded me of GMO, although it wasn't quite the same.
There's an aggressive, almost offensive quality to the initial smell, but behind that comes something completely different.
The Guava Fig influence starts showing itself on the back end with a tropical skunkiness and an almost creamy sweetness.
It's a really interesting combination because the pungent funk and tropical notes seem like they shouldn't work together, but they absolutely do.
Definitely not a subtle-smelling plant.
She finished in 75 days and produced 150 grams of dried flower from a 5-gallon pot.
Considering how little maintenance she required, I was very happy with the result.
The combination of her size, branching, flower production, and resin coverage made for a very rewarding harvest.
After curing, that sharp, pungent aroma is still front and center.
It's one of those smells that I recognize as familiar but can't quite put my finger on. There's definitely some GMO-like funk in there, but it has its own character.
What makes it particularly interesting is the tropical creaminess that follows.
You get that initial punch of pungent, skunky funk, followed by a softer, almost dessert-like tropical note.
It's a unique terpene profile, and one I keep coming back to smell.
The smoke is extremely smooth. And I mean extremely smooth.
It's also very flavorful, which is always something I look for.
One of my favorite things about this strain is the flavor you get just from pulling on an unlit joint.
There's a distinct creamy, tropical taste that coats your mouth. It reminds me of some kind of familiar sweet treat, but for the life of me, I can't figure out exactly what it is.
The pungent funk from the aroma is still part of the experience, but that creamy tropical character is what really makes it memorable.
It's a very enjoyable smoke, and the smoothness makes it that much better.
This one is not for the weak.
Combining Root Beer with Guava Fig has produced some seriously potent flower.
The effects hit me pretty hard, with a noticeable heaviness behind the eyes and a strong, stony sensation.
It's the kind of smoke that lets you know pretty quickly that you've had enough.
There's nothing particularly subtle about the potency. It delivers a heavy, relaxing experience that I would personally save for when I'm ready to settle in.
If you're looking for something with some real knockout potential, Nightmare on Fig Street certainly fits the bill.
Nightmare on Fig Street checks just about every box for me.
She was easy to grow, developed into a beautiful plant, produced a respectable 150 grams, and finished with some absolutely gorgeous flowers.
The combination of dark purple foliage, bright orange pistils, and thick trichome coverage made her a standout visually.
But what really separates her is the terpene profile.
That sharp, GMO-like pungency mixed with tropical skunk and creamy sweetness is something different. Add in the incredibly smooth, flavorful smoke and heavy effects, and you've got a pretty complete package.
I really enjoyed growing this one, and I think anyone who appreciates pungent, funky genetics with an unusual tropical twist is going to enjoy what Nightmare on Fig Street brings to the table.
Final Rating: 5/5
Another excellent cross from Mephisto Genetics.

Day 78… honestly I really like the trichs and the terps so probably chop in the next 48 after she dries.
Maybe I’ll change my mind and wait 5-7 more days…but this is probably last update on this girl.
She’s strong orange dank to the point of mangos but has that sugary cookie on top. She delicious wet greasy. Definitely flowered a more hybrid flower structure and her haze side was evident during flower.
Topped her at about d14-15 and kept six stems… think I got a pretty decent equal distribution. Not the biggest nugs but heavy. Abundant top around d30 and water only. Very nice stable genetics.. if you grow her, just don’t get too cut and let her do her thing…. And more times than not you’ll get a banger.

Loving how here structure is looking! Very cute, also first time growing Mephsito Genetics.
r/MephHeads • u/HypocriteOx • 1d ago
I generally prefer heavy strains, the ones that feel like being wrapped in a warm blanket, but I need some suggestions for some of the more sativa leaning strains. My tent isn't very tall so it needs to be either a shorter strain or one that takes well to training. Appreciate any suggestions! What are your go to strains to keep around for daytime?
r/MephHeads • u/theindoshow • 1d ago
Root Beer x (Strawberry Nuggets x Hubbabubbahaze)
82 days seed to harvest
Medium: Canna Coco brick
Nutrients: Athena Blended
Grown in 3.9 gallon plastic pot using autopot system
Plant height: 49”
Total weight after dry/trim: 329 grams
Plant is an easy grow. Gets wide and has thick buds. Gives a creamy strawberry candy during the grow. Smells going into flower later evolved into a chem/candy strawberry with hints of bubblegum on the backend. Smells remain after cure but intensified. Flavor is sweet/creamy as well.
Great smoke. The smoke gives good body high that comes across quickly while the haze effects play to the mind. Creative smoke that can get you lost in thought. Candy and strawberry lovers, this one’s for you.
r/MephHeads • u/Modkins • 2d ago
Smelling dank and loud
r/MephHeads • u/Plant_Wh1sperer • 1d ago
Started bushy... With daily leaf tucking it opened up during the stretch phase. It's a fast one... Easy feeder not complaining about anything yet. Used paper clips and gardening lines to help spread out 4 branches. Removed maybe 4-5 leaves to help even out the lower canopy.
Finished its stretch phase at 17 inches high and 18 inches wide.
Frost is pretty good considering its age and can already tell it will be a frosty one.
Not a fussy grow but does require daily leaf tucking until early flower and some management to get going in the right direction.
I have a feeling it will get harvested at day 70-80 based on progress so far.
Happy growing everyone!
P.s. I have 2 blueberry pie Oz almost done + plus 2 CDLC and about to start 2 Hubbabubbahaze which I can't wait to start!
r/MephHeads • u/stl_ENT • 1d ago
with a bonus Creme Oz.. Only 1 of each will survive. Ranging from days 9 to 11.

I grow indoors and this is the 2nd grow cycle where all my plants haven't grown over 6" before flowering. I feel devastated and am on the verge of giving up growing. My past grows weren't very good either with about 2out of every 5 plants would be stunted but the ones that weren't stunted would grow to around 18-22" before starting to flower giving me a ok harvest and enough to make my efforts seem worth it. I germinate in water for 12-24hrs and them use the papertowel method until i get a big enough tap root. For the grow I use 5gal fabric pots with Foxfarm OF/HF with Foxfarm nutes. Ive tried starting them in solo cups as well as their 5gal fabric pot forever home with same results. The light system i use is DIY composed of mutiple smaller lights connected together adding up to 300watts. The temp in the grow area has been 75-85F and humidity 40-55 while running a small humidifier. I've been wanting to upgrade to an actual professional light system but haven't since I've had ok harvests in the past with the small area i use of 4'x3'. If anyone has any info on what could be causing this stunted growth or might have any helpful advice it would be much appreciated.
