Also answering to the name “Magnum OG,” Magnum is a unique, perfectly balanced auto-flowering indica hybrid strain that is known for leaving you chatty, happy, and ready to laugh for hours. Its exact origins are known only to its breeders at Buddha Seeds, but it is assumed to be a mix of indica, sativa, and ruderalis with the ruderalis keeping its THC level at a low 10%-15%. 


How will Magnum cannabis make me feel?

Don’t be fooled by Magnum’s rather unimpressive looking, almost-chalky-white, crumbly, amber-haired nuggets as it actually provides a truly wonderful, mood-lifting high that gives you a sense of levity and makes even the most introverted feel talkative and social as a relaxing body high that won’t leave you stranded on the couch soothingly and progressively courses through you. 


What are Magnum’s therapeutic effects?

Medically, it has the potential to treat numerous conditions, so consult with your physician to see if it’s right for you. 


What does Magnum cannabis taste like?

When it comes to aroma and taste, Magnum has pleasantly pleasing piney, floral, and sweetly earthy notes.


Is it easy to grow Magnum cannabis seeds?

For even the most inexperienced of growers, Magnum will be boosting your confidence in no time as it is considered to be one of the easiest marijuana plants to grow and reach 5 feet in height! While indoors is considered the ideal setting, Magnum can be grown outdoors and should be ready to harvest in 11 weeks with a yield of 4-9 oz per plant. Indoors, provides a handsome yield of about 19%-21% oz per square meter in 7-9 weeks.

Whatever Magnum lacks in looks, it makes up for in every other aspect–it’s a happy, sociable high that leaves you feeling good about yourself and life in general, is easy to grow, and even tastes and smells great!

    Magnum is a powerful strain with sizeable nugs. It’s a nice grow! I have little experience with MJ before working with GCS, but hey! I love a good challenge and the blog posts help a LOT with helpful weed-growing advice. Feeling like I am part of a great community. Thanks for the opportunity. Just wish I could post photos.

    I’m generally a pretty quiet and shy person, but when I use Magnum you’d think I was a super extroverted person. My friends (lovingly) joke that they always know when I’ve been smoking some Magnum cuz I suddenly can’t stop talking. They call it “gettin’ Mag’d” cuz of the strain and my name!

    I have been cultivating mj for many years and just recently came across Gcs. Their seed selection really blew me away. I never knew there were so many seeds to buy online! I know a lot of the farms they source from in Northern Cali, and they are all awesome people. A truly magnificent strain to grow for yourself. Not only is it delicious it is fulfilling and nice to have around!

    Okay! So I bought 10 seeds online and they shipped out to my location in about a week. They arrived in an air-sealed package, very fresh and ready to growwwww!

    I was off to the races….got the seeds in the ground STAT! They were quick! 10 weeks after planting I was almost ready to harvest.

    My nugs were fresh and very sticky, COVERED in fresh trichomes. Nothing better than fresh weed like this!

    Magnum is a fitting name for this high energy strain. It produces gorgeous flower…very tall plants, and a whole lotta BUD.

    My suggestion, if you seek it, is to read up on the blog section of this site. Learn a thing or two about cultivating weed before you dive in. That’ll be SURE to increase your yield.

    I had a deep love for this weed, and whenever I feel anxious or stressed, taking a few hits of this stuff puts me straight. It’s a fun grow….and it does take a lot of effort and time. There’s great growing instructions online. You can really learn a lot just by reading over these blogs.
    I wish I could post pictures of my plants….they’re super tall and smell great! Even my cats seem to love them….hmmmm

  19. Verified Owner

    Magnum weed is pretty unique and is perfect for smokers who greatly appreciate a good sativa high and a great body buzz. The yields are incredible. I usually harvest over 500 G of pot from just 5 seeds. I am averaging over 100 G per plant….easy harvest and high quality sticky flower that’s great for smoking after work. I don’t think I’ll ever go back to buying from the dispensary….the quality of howgrowm is really out of this world.
