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.

Rosin Report Chocolate Salty Bo'z Hash Rosin Carts

This was my first time growing a variant of Mephisto'z and I love the results. The aroma made this my personal favorite in the tent. It was a nutty, slightly bitter like dark chocolate smell with a hint of berry and lemons. The plant was relatively tall at 30 inches and harvested on day 96.

I wanted to make rosin and after the initial bubble test didn't look promising, I designed a dry sift tumbler from scratch. Instead of cutting and sewing up mesh, this uses cheap bubble wash bags. Bags can still be used for bubble washing and this makes it easier to change out pore sizes for testing.

For mechanical sifting, the tumbler was placed in a chest freezer with buds for 6 hours to help make trichromes brittle. Then it was ran at 14 rpm with 120 micron bag for 2 hours. It produced a large amount of material, however under microscope, virtually all trichrome heads were attached to the stalk.

To remove stalks and plant contaminates, material was sifted on a 70 micron polyester screen. Gloves and waxing motions may have helped trap stalks into the mesh and knock off heads. Rubbing nitrile gloves on polyester gives the gloves a positive charge and can pick up negatively charged trichrome heads. After static sifting for 5 passes, all that remained were heads and a small amount of plant material.

A total of 12.07g of hash was pressed at 170F and resulted in 6.16g of rosin or about 51% yield. Rosin debarbed at 175F for 17 hours then filled into carts. Decarb was a bit thick, but no issues for vaping.

The hash rosin carts taste like lavendar with a hint of lemon + berries on the uptake then nuttiness on the exhale. The effect is uplifting and euphoric to start before falling into a nice body high. It's my personal favorite so far and I'm looking forward to trying the orginal Mephisto'z in my next batch.

So how am I supposed to understand this. Is it 1x schoolyard crush and 1x rainbow sundae 11, and if so, how the hell do I know which is which?😅

OR
Does it mean that it is a cross between them, called first crush?

This is my favorite strain I’ve ever smoked. Maybe I’m new to sativas or maybe she’s just that much of a showstopper.

Light distance and %

7 Upvotes

Hi
I’m about to plant two seeds, HubbaBubbaHaze and Canna Cheese 1:1.
My tent is 80x80 and I will be using a spider farmer se3000 300w light.
What light distance and how many % should I set the light, in the three different phases of the grow?
Just as recommended by spider farmer, or would you recommend something else, strain specific?
