2.O'z Release + Grove Packaging Overhaul + Store Update

Hi friends,

This is a massive update, please see the blog post for all the info.

Link - Blog Post

New Mephisto Genetics x Grove Bag packaging, new pricing and at last, the 2.O’z release is all scheduled for FRIDAY AUGUST 21st 1pm EU, 12pm UK, 7am Eastern, 5am Pacific.

PLEASE NOTE: In preparation for this huge change, our store will be closed from Wednesday 19th until the drop!

The Search For The New

You might have noticed it was all a bit quiet on the Mephisto front recently, but that’s for a very good reason. We’ve been planning a packaging refresh for what feels like endless years now, but other things always got in the way of such a massive and time consuming task. Last year the team finally managed to make enough time to start thinking about it more seriously, and when we were chatting to Grove Bags about the new Mephisto 1/4lb bags, the stars seemed to align and now, we’re proud to reveal the latest Mephisto Genetics x Grove Bags collaboration.

Our packaging has stayed more-or-less the same since our very first real seed packs launched back in 2015. We gave it a minor update five years later, but all we really did was swap rectangular packs for square ones. So around 2021 or 2022 we started thinking about updating to something a bit more modern, more lavish, more Mephisto. We looked at everything on the market: tins, wooden blocks, blister packs, you name it, if it’s out there we looked at it. In the end, our goal was to find options manufactured in either the United States or Europe. We wanted a design that was unmistakably Mephisto, rather than something destined for a dumpster the moment it reached a Meph Head. We threw around ideas for a long time and could never really settle on the most immediate part, the material of the packaging, much less the design of the thing! We took a trip to MJBizCon, meeting with over 20 manufacturers, including a few specializing in compostable packaging, but nothing hit the mark. So when Sonja had the kinda out-there idea of using Grove Bags, everybody on the team had a collective facepalm moment for “why didn’t we think of that before?!

So why Grove Bags?

Firstly, we love Grove. They make a great product, they source and manufacture in the US, and they’re all super passionate, friendly, knowledgeable and, most importantly, have a huge Meph Head on the team who originally reached out for a collaboration in the first place. 

Secondly, although we’re not exactly eco-warriors, we did want a life for our packaging beyond its initial use. Our company has been built entirely on word-of-mouth and the passion and dedication of Meph Heads around the globe. We’ve always had the “sharing’s caring” ethos, our extra seeds and freebies were always given with the idea that if you have too many beans, share them with a friend. Well, with Grove using their TerpLoc® technology in our seeds bags, you can not only share beans with friends, but give them a stored and cured nug to sweeten the deal. Beyond looking great on the shelf, our hope is that as many Meph Heads as possible find their own unique and creative ways of re-using these bags, giving them a second life and helping cut down on a little extra plastic waste.

Did Grove Bags really use TerpLoc® on tiny bags?

Yes! Yeah, you’re not going to be able to fit your entire harvest in the bag your seeds came in (unless your name is DK), but you will be able to share a nug with a friend in something that will keep it in prime time fighting shape.

Use it to tuck away a choice sample before the rest of your stash gets smoked or pressed, think of it like a sticky little piggy bank, or a Mephisto scrapbook of past grows. They also make ideal travel pouches for parties, hikes, fishing trips, or, you know, when you’re trying to complete your history report in a Circle K parking lot. The world is your oyster, and your nugs can go with you.

2.O’z - The Return of MephistO’z

I’d have called you a madman if you’d have told me we’d be doing a second run out of MephistO’z Limiteds after its initial release. To say it wasn’t smooth would be a little bit of an understatement. But the Meph Heads gathered and grew and the results spoke for themselves. MephistO’z has cemented itself amongst the Pantheon of Mephisto strains, a first round draft pick to the Hall of Fame and is well on its way to getting a coveted place up on Mount Mephmore. In the two years since we first released MephistO’z (under a different name, for legal reasons) our social media has been bombarded with requests for practically every strain in the catalogue to be given the O’z treatment. Finally, we relented, and the only real solution to picking which strains got the second round of O’z was to put it out to a community vote.

Meph Heads do community involvement like few others; the voting for the O’z crosses was a full on World Cup of Meph; we had group stages, groundroots campaigns, gangs forming, arguments, love-ins and a knockout round that got feistier than a lock-in in a Pitsmoor alehouse. Eventually the community managed to select their 8 champion strains to be crossed with O’z, and the Mephisto staff also selected their 4 worthy runners up to join the lineup.

2.O'z Release - August 21st, 2026

Hi friends,

MephistO'z 2.O'z is set for release on Friday, August 21st.

I know a lot of you were expecting to see the release this morning, but we had to push it back until Friday. We know this is frustrating, and we appreciate your patience. We're working on a complete packaging overhaul, and with some logistical and shipping headaches, it's taking a little longer than expected. Simultaneously releasing a new product line in 4 different countries is an enormous challenge. Our goal for Mephisto is to provide the same experience across all storefronts, so it's important to make sure we have all our ducks in a row before a major release like this.

A full blog post with strain details, a Grove Bag packing update, and more is coming soon. We'll post the full update when the blog is live.

4th Of July Sale - Retiring Strains

https://preview.redd.it/coc5gdi3t0bh1.png?width=1080&format=png&auto=webp&s=0a628ef6e761c10558d1ea7b3a014394dae0b622

Happy 4th of July Weekend, Mephheads!

Last chance deals are now live for retiring strains. These strains will be 50% off through the weekend and 35% off through the end of July. Limited deals range from 10–30% off through the weekend.

We know this is going to be a controversial list, and it's one we've been mulling over for months. As Tim said, "It's like picking which child you want to get rid of," but unfortunately we can't keep all of our creations. As we continue to focus on developing new Photo to Auto conversions, there are a limited number of reproduction spots available, so we have to be choosy about which strains we'll restock in the future while making room for new projects.

With all that said, some of these strains have been available for the better part of a decade. We're extremely proud that they've stood the test of time and remain personal favorites for many of you. We've thought hard about our selections, and we believe the catalogue is set up in a way that lets you find something similar, or even a direct descendant, of any retiring strain. We hope you can still enjoy your favorite classics through our other offerings or when they appear in Limited crosses. It's certainly possible we'll change our minds, or a Reddit uproar forces us to bring back a fan favorite, but for now, it's time to say goodbye.

-50% Off — Last Chance to Buy:
Chemdogging | Fantasmo Express | Forum Stomper | Grape Crinkle | Livers Bx1 | Orange Diesel | Pigletta's Purple Haze | Pink Panama | Ripley's OG | Samsquanch OG | SODK | Super Orange Haze | Walter White Bx1

-30% Off Limiteds:
Dosidelrium | Appletizing | Old School Blues | SYC

-20% Off Limiteds:
505 Headbanger | Mango Runtz | Beary Berry Punch | Kiwi Lime 1 | Apollo Haze | Gelauto 33

-10% Off Limiteds:
Guava Fig | Bear Force 1 | Butters Breath

We hope you have a fun and safe weekend.

Rainbow Sundae 11 Artisanal and Limited Release

https://preview.redd.it/g26iisxcrf7h1.png?width=540&format=png&auto=webp&s=51a27b1fcb42f60f27146c557b5f063cd5eeeea6

RAINBOW SUNDAE 11

Genetic Heritage: RS11 [Doja Pak/DEOFarms/Wizard Trees] x Sundae Thumper

Seed Type: F5 Feminised Automatic

Videos: Seed to Harvest

Blog: Blog Post

Project Introduction and Overview

Select your character, line up on the grid and wait for the countdown to hit 2 before slamming on the gas. Rainbow Sundae 11 is about to take you on a high-speed rip down the Rainbow coloured unpaved highway (because I don’t want to get us sued with this one). So grab a friend and buckle up for some couch co-op gassed up giggles. 

Doja Pak is a bit of a legend, let’s be honest. The strains he’s popularised have become modern legends and have already made their mark on the industry permanent. Bred by DEOFarms (Deep East Oakland Farms), RS-11 is pretty much the pinnacle and leading light of the candy-gas craze that has been the tippy-top of the industry for a long while now, and it doesn’t seem to be getting blue shelled out of the lead any time soon. We knew as soon as we got our hands on the OG cut we needed to give it the Mephisto turbo-boost.

We had so many options to choose from when it came to the pairing for the RS-11 cut. I’ll be honest, we must’ve crossed most of the Mephisto library to our cuttings to figure out what would really do RS-11 justice. In the end, we just couldn’t move on from one of the very first crosses on our experimentation journey; the award winning Sundae Thumper. Sundae Thumper was a pivotal strain in Mephistory; along with Iced ‘n’ Baked, our Gelauto series from 2023 really showed that we’re not slowing down, and don’t plan to any time soon. When Sundae Thumper won the Best Hybrid award at 2025 edition of the American Autoflower Cup, our reaction was pretty much Nate Diaz; “I’m not surprised, motherFers.”

Rainbow Sundae 11 is sweet and tart, a zesty lemonade infused with a heavy hit of exhaust gas and a refreshing, almost minty finish. A first-round draft pick for the candy-gas craze. She has dense, lightly purpled buds and gives you a euphoric, uplifting experience; the kind of rush you only get from acing the Star Cup and leaving the other players in the dirt. Her resin production is off the charts, generating a blanket of shimmering trichomes that’ll act like a well placed banana peel on your trim scissors come trim day. Combine all of that with high yield potential, size and a forgiving nature that novices will appreciate, Rainbow Sundae 11 could genuinely be a drop of the year candidate for every Meph Head.     

Rainbow Sundae 11 more than earns her place amongst the upper tier of the Mephisto library. She’s an S-tier pick, the kind of overpowered, first-pick character that you’re expecting the devs to nerf in the next patch. Except Mephisto isn’t the grunt fantasy Arrowhead studio, so the fun of Rainbow Sundae 11 isn’t getting patched out any time soon. (Sorry Helldivers, we still love you 💚). 

Strain Behaviour and Structure

Yield, size, flavour, press-potential and forgiving to grow. Rainbow Sundae 11 might just have it all. Let’s delve into it.

Rainbow Sundae 11 shows impressive early vigor, exploding into the vegetative stage with thick stems and sharp, beautifully serrated 7-to-9-finger fan leaves. In our testing, she responded to her container volume; in more restricted root spaces, she forms a compact, well-spaced candelabra physique, while given more room to roam, she stretches out into a dominant, large-framed pine tree structure with strong lateral branching pushing hard from the lower nodes. She responds beautifully to basic canopy management, requiring only moderate leaf tucking and selective defoliation to keep light penetrating to the lower sites.

Because of her vigour, especially in her lateral branching, it’s noteworthy that you should have some kind of structural support on standby to help keep her frame intact. Jimbo noted in his own grow that despite a fluctuation in his pH levels early on, Rainbow Sundae 11 bounced back the quickest and strongest of all the testers in his tents at the time.

Rainbow Sundae 11 is well-tempered and not particularly prone to any stressors, as with most autoflowers, if you get her off to a good start then you should be golden for the rest of her cycle. She isn’t a particularly heavy feeder or waterer, and combine that with her bounce-backability, she’s a strain we could easily recommend to both novice and experienced growers alike.

The bloom cycle for Rainbow Sundae 11 is a spectacle to behold. Plants fade into a starburst yellow to lavender senescence with multiple hues. Purples creep through in the bracts and sugar leaves as dense, golf-ball-sized buds swell along each node point. Frost production is off the charts, with shimmering trichomes completely consuming every floral cluster, creating an industrial, glue-like resin that is incredibly tactile and sticky. The sheer weight of these resin-heavy, rock-hard nugs will cause the outer branches to bow outward, making support ties mandatory at this point, if you haven’t already offered her a helping hand.

Once into mid-to-late flower, the smells on Rainbow Sundae 11 really take off. Aromatics on the vine come in initially tart, lemon forward and with a gassy essence. Those notes eventually transition into a much sweeter cream candy forward profile while still maintaining much of that dominant lemon and gas. You get a touch of the Sundae Thumper parentage with the overly sweet creamy elements happening in the body of the profile. As a finish, the gas note manifests as a minty-infused lemonade.

Combine the killer colour, density, and aromatics of Rainbow Sundae 11 with a sugar-rush-style euphoric effect, and you get a guaranteed crowd-pleaser. Jimbo has used this as his daily driver for the last several months and it remains one of the undisputed champs for motivation and productivity. You get just shifty enough to respect the strength of the flower without it becoming too overwhelming. It’s functional, but much more heady than our more focused higher ratio sativa dominant selections. The strength is a bit high to be used for creative focus, but energetic enough to keep you off the slump. She’s a solid choice for recreation and any kind of summer-time social event.

A 5(+1) pack of either Confetti Sundae or Lime Light will be included with all orders containing either Rainbow Sundae 11  3(+2) seed packs or Rainbow Sundae Limited Edition seeds until 11:59 pm PDT on Sunday, 28th June*, or while stocks last, whichever comes first. This does not affect your normal freebies.*

In addition, we have a tasty surprise for early adopters! We’re giving 20% off these new Limiteds for those who purchase 4 or more packs of them during their first two weeks of release. Offers end at 11:59 pm PDT on Sunday, 28th June, or while stocks last.

Mephisto x Grove Bags

Today also marks the release of the new 1/4lb Mephisto x Grove Bags. Ever since the release of our first grove bag you all have been asking for a bigger size. The new soft touch 1/4lb bags with improved zipper is available in three new designs.

Our new Mephisto x Grove Bags will be available in singles (you pick the design) or bundles of 3 (1 of each design). We know you’d love to be able to mix and match and bundle your own, but we want to be as streamlined as possible and make sure you’re getting what you’ve ordered. You’ll get a small discount for picking the bundle option, but you won’t be financially punished if you want to load up on singles of a particular design (it's the one designed by Jim Connolly, isn't it? @jimconnollydraws78)

Short Summary:
Lemon fuel to gassy cheesy danish in the grow, bakery case on the cure, and a menthol ambush on the rosin dab. 196 grams from a hungry feeder with 5/5 trichomes and a press that confirmed the whole story.

Site Update + New Monthly Freebies

Hey Meph Heads,

We wanted to share a new site update we've been working on. Site filtering has been a long and tested battle for us and for the customer. We tried some nifty things like quizzes that helped pick your strain, or new categories to help filter your options. But with every update it seemed like a new problem popped up, or filters simply weren't working properly. Some of this is just limitations within Shopify or special circumstances due to our regional store differences. Anyway, we put together a new page to filter by release! We hope this makes sorting through the catalogue a little bit easier. This page is still in testing, but have a lookie and tell us what you think!
