Sirius Black strain Seeds

What makes Sirius Black marijuana so enticing? Maybe it’s the striking colorway, its potent THC content (it tops out at a magical 25%), or the fact that it was named in honor of the shape-shifting magician of Harry Potter fame. Whatever the reason, Sirius Black is an impressive strain with major potential. 

Deep purple-hued flowers characterize Sirius Black marijuana, a color directly contrasted by the twisted yellow pistils and bright green leaves that encircle the dense buds. Aromatically sweet with notes of grape and berry, Sirius Black is a smooth smoke that is thick and floral when exhaled. The uplifting cerebral high of Sirius Black empowers creativity, reduces stress and depression, and helps to control pain, seizures, and inflammation.  

Good news for beginner growers – Sirius Black marijuana seeds come by their deep color honestly: it is purported they do not require the standard “cold shock” treatment in order to maximize these brilliant hues, and climates typical of indica dominant strains will suit Sirius Black just fine. Of course, if you prefer indoor gardening, you can expect it to thrive regardless.

    Sirius Black is one of the most potent strains I’ve ever had the pleasure of smoking. It hits hard and fast, leaving me feeling euphoric and relaxed It’s great for easing muscle stiffness and pain. Quite potent though, definitely not a strain for those with low tolerance. Highly recommend if you’re looking for a strong and effective high.

    This weed is deserved of the name sirius black for it’s deeply hued nugs and thick, mysterious smoke. I can usually grow this outdoors, have had a few problems in the past with pests and temp control, but usually I get a medium-high yield, with fresh nugs (not moldy) and a great shelf life. I smoke this weed all through winter and order new SB seeds in the spring. Great hobby!!

    If Harry Potter isn’t your thing, fret not, sirius black is a weed that can be enjoyed by all!! It’s a deeply earthy indica with some really nice flavor! Buying online was a dream, made it sooooo easy to get my seeds delivered….It’s never been this easy before….thank online ordering for that 😉 I’ll be sure to buy more weed!!

    Been a weed grower since I was darn near in my 20s, and It always just gets better and better! The genetics on pacific seeds are some of the best. I am always getting high yields, and I barely even have to try! I can’t wait to be growing in a greenhouse, should be an excellent way to unwind and relax. I hope I get a chance to buy more with my next paycheck *fingers crossed*

    I get why they call is sirius black….cause the flowers are a deep purple and black color and the buzz is Magic!! That’s pretty cheesy I know, but for all you nerds out there, I was able to yield 500 G between 3 plants. Thats OUTDOOR. Bet you I could grow twice that amount in a greenhouse. I just grow as a hobby but this weed is commercial quality no doubt.

    Nothing like some fresh homegrown herb….My sirius black grow was honestly a “siriusly” good time! Deep colors and dense foilage, mixed with large crystalized flower make this one of my favorites. I smoke it most nights to unwind. It’s indica heavy and puts me right to sleep when I need it. I’ll be sure to buy again. Thanks PSB!

    Even if you’re not a Harry Potter fan, you will most definitely enjoy sirius black. This colorful grow makes any greenhouse look and smell much better! I am SO happy to have this weed in my life! I can’t believe how reliable shipping was. These people really know weed and they’re always willing to help out!

    Pretty darn close to Magical, sirius black is a SERIOUS strain for some serious growers:) High THC (round 25%) is the perfect way to unwind at the end of the day. I had a great time growing, even though I have no prior experience. I am just a harry potter fan and HAD to buy this online 🙂
