Connecting Cannabis Cultivators with Cannabis Enthusiasts


Genetic Threads is a monthly Box Club for Cannabis Enthusiasts. Each month, we team up with a cannabis grower, breeder, or producer and collaborate on a custom shirt.

Our mission is to share their story with cannabis enthusiasts to better appreciate the people and companies behind this industry. Our Box Club automatically delivers a unique shirt directly to your door every month- highlighting the hottest genetics on the market. It is the first of its kind in this industry and the result is a fun and unprecedented collaboration of genetics, culture, and apparel.


Free Shipping. No Contracts.




The shirt is tastefully designed with wearability in mind. These are shirts that you can wear comfortably in public and each shirt depicts a featured grower, breeder, or producer with a clean graphic that discretely captures the essence of the icon.


Learn the story behind the shirt. Each box includes an interview with the featured breeder, which gives the them a chance to tell their story in their own words. 


Stickers are just cool, so we send ‘em to you every month. 

Member Perks

Coming soon. Our members will also enjoy discounts and coupons on all sorts of industry goodies!

GENETIC THREADS:    In a few sentences, can you tell us where and when you got your start?

RICK @ MOSCASEEDS: As a breeder is was simply trying to preserve the Cinderella 99 strain by making seeds.  One of my best friends, at the time, was Gerrit Slot, head breeder with Magus Genetics. He helped me understand the principles of breeding and the artistic aspect of breeding. Cinderella 99 was a cultivar I connected with and never wanted to lose her.  This is when I took to working the 5 main lines of Cinderella (all of which came from Brothers Grimm seeds).  The seeds were given to a High Times Cultivation Editor, Crazy Composer, who wrote a blog on his grow using my Cinderella 99 seeds.  He stated it was the best expression of the Pineapple pheno of Cinderella 99 he has ever grown!  Soon after this everyone wanted seeds...and the rest is history!!

GT: What was the first strain you ever grew?

MS: Sixteen foot tall Iowa hemp seeds when I was 13 yrs old.  Was it a clone or from seed? Seeds we had collected from mature seeded plants.

GT: What strains are you most known for?

MS: Preserving and protecting Cinderella 99 and Old Time Moonshine (originally created by DJ Short) and more recently, Raspberry Boogie, Moonshine Cookies, Blotto OGK.

GT: What motivates you as breeder and grower?

MS: Continuous improvement- putting the genetic building blocks together with an end goal in mind.  And, of course, the endless possibilities!

GT: When you approach a new breeding project, what are the top three things you are looking for?

MS: 1.  P1 Breeding stock characteristics and stability.  2.  Are the P1s True Breeding?  3.  Goal of the ideal plant in mind.

GT:  Do you have any special projects in the works you'd be willing to share with us?

MS: We are expanding our Feminized line atm and we are working on a Gas Line and Frost Line. 

GT: Who inspires you in the cannabis industry?

MS: Sjoerd Brookes, Karma, Crazy Composer, Suny Cheeba, Odie Diesel and Josh LaPlata.  Who did you look up to when you first got started? Dutch Breeders: Arjan from the Greenhouse, Gerrit Slot from Magus Genetics and Simon from Serious Seeds.

GT: Do you have any advice for new breeders/growers/producers?

MS: Write down your daily observations!  Grow your own seeds and work your lines to see what the parents contribute to the mix.  You should know your plants  and offspring better than anyone!  What do you wish someone had told you when you first started? Write everything down and spend time observing your plants.

GT: What do you consider to be one of your greatest accomplishments or successes?

MS: Longevity-- being privileged to successfully run a Cannabis seed company for over 10 years and earning praised from the Canna Community for our work.  Growing the plant has really been a Labor of Love-- Passion makes the difference...

GT: What is something you would like to go back and change or do differently?

MS: Nothing

GT: Do you have any breeding/growing tips you’d like to share?

MS: Keep a journal-- always write daily observations down.  Track everything you do in your garden on paper. And grow out your own seeds to see the offspring.

GT: Do you have a “fun fact” about you or your work?

MS: We completed a 5000 seed pheno hunt in Arizona last year!  Also, We started in Europe and cut our teeth there, so to speak!  Mosca Seeds celebrated our 10 year Anniversary last year of being in the seed producer worldwide.  

GT: What’s your favorite part about breeding/growing cannabis?

MS: For breeding it would certainly be growing out our own seeds and observing the offspring we created.  For growing it would be the excitement I get when the lights turn on in our flowering rooms and seeing the lovely ladies swaying in the wind!  

GT: Is there anything else you would like to tell us about yourself and your work? 

MS: We are smokers and we Love the medicinal aspect of the Cannabis plant.  Our passion has made the difference, over the years, in being able to continue this evolving breeding journey... 

GT: How can people contact you (website/social media/email/etc.)?
