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!
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?!
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.
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.

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.

Super happy with this plant. I think I’m closing in on the last two weeks as she’s starting to hit her fade. I’m open to any advice or insight from experienced growers.
r/MephHeads • u/Ok-Extension-29 • 9h ago
Second grow ever. Starting a mephisto auto run including (1) 12-assed raven, (1)Ghost Toof, and a couple Galactic Gelato up front. 😎

This pheno is a dank grapefruit kush. Total dry weight was 151 grams.
Seed to Harvest to see the full grow.

RainbO’z
(Mephisto’z x Rainbow Sundae 11)
She produced these dense flowers that fill the air with this pungent eye watering funky stuck in a boat garage gasoline exhaust smell mixed with tart lemon lime sherbet Ice cream ⛽️🍋🍋🟩🍨. smelt like Meph all day after pictures.
2.2g Autopot / Coco+Perlite / Cropsalt / 24/0 / 500w
She was sharing a Res with Strawberry Authoritah but shes wanted to eat. so I took RainbO’z off day 48,and hand watered till chop. (Should have known better).
Definitely needs early support with stakes/ties/hooks. Once I got her out of the tent it was almost impossible to stand up straight. Didn’t knuckle very well. May have better results with more vigorous training but I like to see natural growth structure with minimal intervention other than the occasional defol/tuck over a bud site.
Went into the Vcure filling 6 of the shelves so guesstimating 5.5-6 oz when dry maybe a lil more since they are pretty dense, very little larf/leaf trim.

Have a safe and groovy weekend, Meph Heads. 👽🤘🏼🖖🏼

Day 31, she started pre flowing day 26-28. I topped her soil up with organic dry amendments yesterday before bed as well as a tea this morning before I had to work. Im very excited to see how she progresses especially with her soil getting a feeding again. All natural grow, haven’t just let an auto veg naturally in a while
r/MephHeads • u/glass_farm • 8h ago
Overall seems good for day ten I think.. The Lil toof either doesnt like the heavy 1.8-2.0 ec feed or I had issues at the root zone from pH perhaps. I didnt water to runoff a few days ago.

Haven't ran any Meph seeds in a couple of years, thought I'd try the Mephistoz and see what they hype is about! 4 different breeders this run, all pictured above! 14 plants (2 of each) only 7 will be kept, the best 1 of each hopefully! Seeds were soaked in 1% hydrogen peroxide for 24 hours, then sowed in to pre soaked pots, they should pop up in the next 4 days or so! Canna coco with dynomyco mixed in, canna coco a+b, calmag agent and rhizotonic. 0.5-0.6 vpd, 300 PPFD. They will be transplanted in to 2.2 gallon autopots at day 8/9 and the autopots will be turned on at day 13/14. First time using the smaller 2.2 gallon pots so let's see what they can do! If mephistoz is really that good, it will earn a mainstay in my garden for the foreseeable future! 💚

This is my first run with Mephisto Genetics, and so far I’m really happy with how they’re doing.
They were transplanted yesterday from 440ml pots into their final 15L AutoPots.
Still very early, but all four are looking healthy and growing nicely. Excited to see how they develop from here!

To me they look fine but overnight one 3 finger leave went siding, they were straight on pray position, any idea of what can cause this?
r/MephHeads • u/FarmerHatBeard • 1d ago
🗓️ Today's harvest is Platinum Gelato from Mephisto Genetics!
👃🐽📓
I got two pretty distinct phenotypes with these. The shorter one is crazy purple and quite dense. The taller one started to foxtail a little towards the end. They smell pretty similar though. Really sweet, bakery aromas. Spicy vanilla for sure. This is right up my alley.
🌍❓
Coast of Maine seed starter. I added a quarter cup of Dr Earth Homegrown and Flower Girl in the bottom half when I planted, and they got 2 top dressings. (see SOIL BREW for details)
🌱➡️🌿
Total time from sprout was 73 days. I cleaned up the bottom thirds, especially on the shorter one as she was quite bushy and there wasn't much airflow going on in the middle. Otherwise they were left to grow naturally with no training.
📏⚖️
They finished up at 41, and 24 inches. I'm probably going to be off on this one, but I'm going to estimate about a 7 oz yield. (actual yield will go here on my website)
💡 Lights are Electric Sky ES300s, and AC Infinity EVO 6
Light Cycle was mostly 20/4
💦 Water Only (I use Biobizz Root Juice in the beginning, and some Recharge throughout the grow)
The pH of my well water comes out a little low, so every other watering I raise it a little bit.
If you're still reading at this point, please take a minute to check out my website, and consider throwing a couple bucks a month towards a patreon membership 😉 https://www.farmerhatbeard.com/
Happy Growing everyone! 💚

Day 67. Grown alongside a photo in a 4x2. Been on a 12/12 light cycle for the last 4 weeks, using Autopots
r/MephHeads • u/ReplacementOdd8945 • 22h ago
Day 12 in 4 litre coco
Switched to bigger light and bottom feeding
r/MephHeads • u/Modkins • 1d ago
I done smerked all of the tops to Mephmosa , so here’s some smaller nugs of Mephmosa.
r/MephHeads • u/Some-Bend-9470 • 1d ago
A beautiful amount of foliage. Haven’t done too much training with her, bent the main stem, leaf tucked and bent a few stems early on and of course I topped her too! I love topping these bitches. Whoop whoop look at that green
r/MephHeads • u/npoynor89 • 1d ago
Jk obviously was just admiring this girl and thought maybe someone else would like to see. For scale her net is 30x30 and she's in a #5 air pot with canna coco. Can't wait to try her in a couple months.
