Overview and Genetics

Space Queen owes its remarkable qualities to its dynamic family tree. The offspring of Cinderella 99 and Romulan, this evenly-balanced hybrid strain contains a perfect 50:50 sativa to indica ratio, THC levels of 16%, and a vivid, floral taste.

Some describe Space Queen as earthy and sweet, while others detect a mixture of crisp, citrus notes. While its effects and flavors are appealing to cannabis connoisseurs across the board, we recommend you have a fair amount of gardening experience under your belt before attempting to cultivate this strain.

Typically, it is best-suited to master growers. However, with ambition and care, any motivated cultivator is encouraged to work their way up to producing these plants, where they will then be rewarded with potent, out-of-this-world effects.

When this strain’s characteristics first take hold, you will likely experience mood-brightening effects and pleasant, enhanced perceptions. Once the effects settle in, many describe the experience as a euphoric, outerspace-esque ride imbued with imaginative, starlit thoughts. This strain also tends to alleviate stress, damper negative thoughts, and physically soothe the user.

Flowering Time and Yields

Space Queen is a somewhat difficult strain to grow and is best-suited to a gardener with experience. Beginner growers may want to develop their green thumb with easier strains (such as Romulan—one of Space Queen’s parent strains) first before attempting to cultivate these seeds. Like any discipline, the art of growing at-home cannabis simply takes determination and practice.

Space Queen seeds produce distinguished, statuesque plants and typically have a flowering time of approximately 50-60 days. As photoperiod plants, they are also suitable to both indoor and outdoor growing. With appropriate care, it will produce yields averaging 500 grams per plant outside, and 500 grams per square meter indoors.

Aroma, Taste, and Appearance of Space Queen Cannabis Seeds

Terpenes are a group of chemical compounds that are believed to contribute to both the recreational and therapeutic properties of many cannabis strains. This includes each strain’s distinct taste and cerebral and physical effects. In Space Queen’s case, its dominant terpenes are caryophyllene, myrcene, and limonene.

Caryophyllene provides Space Queen with its earthy, spicy scents. Many describe this terpene as being reminiscent of black pepper and basil. It also tends to produce a sense of warmth thanks to its clove and cinnamon notes

Myrcene is responsible for Space Queen’s earthy, forest-like taste and aroma, as well as its relaxing effects. It also tends to help promote sleep—which makes this strain ideal for those looking to both brighten their mood and lull themselves into a peaceful slumber. Finally, Limonene rounds out Space Queen’s flavor profile by contributing citrusy, floral notes and the aroma of apples.

Appearance and Color of the Space Queen Strain Seeds

A true visual stunner, Space Queen plants are tall, elegant, and lanky, Their regal, distinguished appearance hints at their equally powerful effects. Space Queen plants produce pale green buds with ample resin. They tend to be thickly coated in a layer of frosty trichomes and sometimes contain subtle hues of violet, lavender, and red. Because of their height, indoor growers are encouraged to make sure their gardening space has enough room to allow these plants to flourish.

Where to Purchase Space Queen Seeds

While there are plenty of places to purchase seeds online, not all resources are the same. At Growers Choice, we prioritize maintaining a catalog of high-quality, premium cannabis seeds backed by a 90% germination guarantee. In addition, it’s important to us to provide a large amount of educational information accompanying each cannabis variety. While there’s no substitute for actually growing and consuming a strain yourself, having as much information as possible about a given strain’s effects, growing properties, physical appearance, and more before purchasing makes it all the likelier that you’ll find the right seeds to meet your unique needs and preferences.

When looking for a seed bank, we recommend checking for the following qualities:

  • Premium quality seeds: Growers Choice prioritizes offering a different class of cannabis strains for purchase—and guaranteeing their quality. Whether you’re a grower with years of experience or just embarking on the world of home cultivation, obtaining premium seeds is one of the most vital steps in helping ensure vibrant, resinous plants.
  • A range of seeds: Every cannabis user will have unique tastes. Some prefer indicas, others sativas—some specifically want to purchase feminized seeds, for others still, autoflowering genetics are vital. The list goes on. Each subcategory of seeds should have a multitude of choices with numerous, unique profiles. Finding your favorite strains is a highly individualized process; as such, a larger selection, accompanied by in-depth descriptions, is one of the best resources for seasoned and beginner cannabis users alike.
  • In-depth strain profiles and guides: Home gardening is somewhat of an art. However, this is not to say that aspiring growers should feel intimidated. Equipped with clear, easy-to-follow instructions, any grower can cultivate lush, bountiful plants. As such, it’s important that the online bank you purchase from provides key details on each of their cannabis strains, as well as guides on how to embark on the growing journey.
  • Stealth shipping: Even though home cultivation is legal in many areas, that doesn’t necessarily mean you want the contents of your mail flashily splashed across the container. Growers Choice understands the importance of discreet packaging.

Strains Similar to Space Queen Seeds

Like our featured strain above, the following varieties of cannabis all contain many of the same galactic, imaginative qualities of Space Queen itself. Some contain greater indica genetics, others sativa, as well as varying levels of THC and CBD. However, the common threads between the following strains are that they each meet the Growers Choice standard of quality, and when grown with care, will produce highly sought-after effects, scents, and experiences.

Cinderella 99 Feminized Cannabis Seeds

One of Space Queen’s parents, this strain contains equally regal and magical effects. In contrast to Space Queen, Cinderella 99 contains greater sativa genetics, and produces energizing, citrus-scented plants. One of our favorite classic sativas, this strain is known to sharpen thoughts and improve lucidity. Typically, this strain is best for those seeking an enhanced level of focus, an uplifted mood, and a touch of whimsy. Like Space Queen, Cinderella 99 is also known for its brilliant resin production.

Romulan Feminized Cannabis Seeds 

While Cinderella 99 is responsible for Space Queen’s regal appearance and ability to beam your imagination to new galaxies, Romulan can take credit for its mind-bending traits. A reference to Star Trek, its name hints at this strain’s tendency to transport the user to an entirely new realm of relaxation and sedation. Some describe the experience produced by these plants as a euphoric ride filled with tranquility and haziness. We think of it as similar to drifting off into the nebulous, colorful world of outer space. A pure indica, this strain is easy to grow, and has a flowering period of 55-65 days. Despite its galactic effects, its scent, ironically, is often described as earthy, as is its distinguishable taste.

Alien Feminized Cannabis Seeds

Like Space Queen, this strain is also a balanced hybrid. The offspring of Alien Kush and Tahoe OG Kush, this otherworldly strain tends to transport users to a distinctly exhilarating universe. It contains THC levels of Its THC content clocks in at 23%, while its yields average 500 grams per square meter indoors, and 600 grams per plant outdoors. Diesel-like, sweet, and earthy, this strain has an intermediate growing difficulty level and a flowering time of 50-60 days. It is best suited to users looking to enhance feelings of happiness, thoughtfulness, and relaxation.

Mars OG Feminized Cannabis Seeds 

Like Romulan seeds, this famous strain is also known for its heavy indica component. It is best suited to those who prefer sweet, woody tastes and enjoy winding down into a state of happiness and pine-scented bliss at the end of a long day. Its THC content averages 20% while its yields clock in at approximately 450 grams per square meter indoors, and 500 grams per plant outdoors.

Mercury OG Feminized Cannabis Seeds

This strain contains 100% indica genetics and a THC content of 23%. As such, it’s no mystery as to why it produces such otherworldly effects. Creamy, earthy, and sweet, it has a flowering time of 60-70 days and imbues users with a sense of mellow creativity and physical chill.

Like Space Queen, this strain is best suited to more advanced growers and tends to flower in about 8-10 weeks. We find this strain is best-suited to cannabis enthusiasts looking for enhanced sensory perception and a transcendent, tranquilizing experience.

    Grew in soil, LEDs all but 2 germinated. Super fruity smell at the end. Smokes great and awesome for cooking

  2. Verified Owner

    Oooo what a beautiful and frosty strain! I wouldn’t attempt this strain without experience, but if you know what you’re doing, you can expect fast shipping, even gernination and medium-large yields with beautifully crystalized flower!

  3. Verified Owner

    I’ve grown a few pulls of this strain. Its yields are decent grown indoors. The frost factor is 7/10, cola shape and size is 5/10 and density is a 4/10. Not super impressed with terpene profile as it just doesnt impress like I was hoping. Colas grow tall and thin.

  4. Verified Owner

    High-quality seeds, just wish that my shipping could be faster…

  5. Verified Owner

    It was an overall easy grow and this is one of my favorites in terms of effects. Super sugary, sweet smelling buds that drop insane amounts of kief in the grinder. I knocked off one star because the plant was hermaphroditic, which created a lot of work in flower and did lead to some pollination, but ended up being worth the effort in the end and had minimal impact on quality of the final product.

  6. Verified Owner

    I popped 2 seeds and both are growing like crazy. They are still young but I can already tell they are really great quality from how fast they are taking off. Can’t wait till they are done. I will upload some pics when I switch to flower.

  7. Verified Owner

    Did a presoak, and they took an extra few days to sprout compared to the Gelato and Sunset sherbert (so much so, I started pre soaking another one) but is sprouted and is going strong. The 2nd seed also took a sec to sprout too, either way, very happy!

  8. Verified Owner

  27. Verified Owner

    So far everything is looking good. The plant is healthy and growing outside. I will start another for indoor growth as the summer ends.
    Plant very healthy and I had no problems with sprouting seeds.

  28. Verified Owner

    So far they’re some very healthy babies growing to be beautiful ladies. Mainline seems to make them happy with Nectar for the Gods in 7gal Root Pouches. Growers Choice always makes the experience pleasant from the time you order til jars are full of cured love

  29. Verified Owner

    I am 20 weeks in I started them inside in January and they are now 2 ft tall and looking vibrant and beautiful and smell amazing. I have slowly been moving them outdoors in the yard but here in MA the nights are still a little cool and we have had some heavy rain. I would share photos but I don’t see that option. GC is my go to for seeds I prefer growing outdoors and I haven’t been disappointed. Can’t wait for harvest

  30. Verified Owner

    great strain ,easy grow used natures way super soil along with fox farm ocean forest, RO water with cal nutrients.14 oz in a 4’x4′ of great hippie lettuce .thanks GCS

  31. Verified Owner

    Fast shipping and great genetics. Had trouble with germination but that was my tendency to try to do to much. I did get a couple vegged through and are now 5 weeks into flower. Very tall and hearty genetics, I was pleasantly surprised by the size of the colas and potent bubblegum smell starting to fill my basement. Wish I would have gotten them a week later at 20 for 10 price but at least I saved a couple beans to rerun and clone the giant beauties.

  32. Verified Owner

    Out of the five strains, I grew this cycle the Space queen grew the best overall. Perfect for a first grow.

  33. Verified Owner

    was 3 for 3 with pooping seeds and that was the only up side to this. 2 of the 3 seedlings didnt make it. Just looked weak from the start. The 1 that survived whent 5 weeks into flower and then decided to herm on me. My envornment has been dialed in pretty good this grow. 68F to 74F, humidity at 48 to 58 amd vpd 1.2 to 1.6. The herm pollinated my 2 gold leaf that were really looking epic. Pretty disappointed but things happen.

  34. Verified Owner

    Almost ready to harvest 1st plant, smells awesome

  35. Verified Owner

    This delicious and spacey treat is a gem in the garden. I got 10 seeds and am currently growing 5 of them. They are quite tall and require trellising and caging to keep upright, but BOY do they produce! Excellent flavors and a sharp sour aftertaste….keeps me coming back for more! Lovely delicious little nugs all summer long!

  36. Verified Owner

    Finally got a plant of SQ ..they both growing grt now, got em 5gal buckets. Will post pics soon..btw i did the presoak in cup of water for 24 hrs and then soil. Tried planting them straight in soil and 8 of them didn’t germ, did the 24hr presoak and was fine

  37. Verified Owner

    I popped 4 seeds and had 2 phenotypes. Generally, i only move forward with the “best”, but both are amazing. One has a dominant purple rose colored leaf and one is a dark green. The taste and overall aroma is intoxicating. Great yield and in a timely manner too. I love 8 week flowers.

  38. Verified Owner

    Taste is fine, though I wouldn’t say it is anything like candy. Same with smell, maybe a bit fruity. The color in my case definitely not like the sample pic. Slight purple tint. Could be my light setup? Strong enough for me, but didn’t blow me away.
    I’m going to grow my remaining seeds, but I won’t spend the time cloning them like I usually do.

  39. Verified Owner

    beautiful plant. wonderful taste and aroma.
    very effective.

    shields high…

  43. Verified Owner

    I’ve always had great results from GC.. first Space queen run and everything is going complaints, can’t wait to harvest ?

  44. Verified Owner

    This is my very first run of cultivation and it seems to be a success so far

    Currently in the beginning of week 3 of flower !!

  45. Verified Owner

    First crop was 30% germ. So, I let GC know, and voila! Ten seeds showed up quickly. This crop 100% germ.
    They’ve been strong growers but a bit sensitive to inorganic nutes at 1/2 strength. After a good and proper flushing I started them on Organic nutes and they are happy girls. Also use 1/4 strength Cal-Mag+ every other watering.
    GC rocks it. Buy with confidence!

  46. Verified Owner

    I grew this one outdoors this past summer here in Michigan, topped her all the way until end of July. She was 20′ in diameter and pulled 3 lbs 7 oz of dry flower.

  47. Verified Owner

    I am about 3 weeks from harvest! Finally! Yes, I did have some issues with did have some issues with sprouting but I’m a newbie so assume I did something wrong. I purchased this pack because I live in a high-humidity area and these varieties are supposed to due well in high humidity. I’ll do another Space queen but try a Sunset Sherbet this time. Small tent so I can only handle 2 plants at a time. Appreciate the quality seeds from GC .

  48. Verified Owner

    Great experience east strain to grow.Smells & looks great!!!

  49. Verified Owner

    Couldn’t be happier bought 5 seeds germinated 2 popped in 1 day about 2 weeks to finish can’t wait

  50. Verified Owner

    This is my very first time experiencing Space queen , and I am 1000% IMPRESSED!!! I’ve never been an indica smoker because of the couch lock, but this smoke is UH-MAZING!!! I have *0* couch lock! I’m in a great mood, and I’m relaxed. Due to being excessively clumsy, I hurt every where all the time. I have arthritis every where. But I have absolutely 0 pain anywhere. This is an amazing smoke, and I’m now a lifetime patient!!!!

  51. Verified Owner

    1st outdoor grow, started indoors in April, moved outdoors in 3 gal pots(I know that held em back, it’s all I had) harvest in late September and got 5 ounces per plant. Nice an relaxing smoke, friend used some to make butter and the cookies were phenomenal. Great high, relaxing, not sleepy and no paranoia. Gonna do larger pots next season.

  52. Verified Owner

    I’ve been growing for about a decade, so Space Queen was pretty easy, but I definitely would tell anyone who is new to cannabis cultivation to wait until they have some more experience before growing this beaut. SOG is my preferred method for growing this one, and GCS is my preferred seed bank to order from!

  53. Verified Owner

    Over all my experience has been not bad. Had a few seeds not germinate but GC promptly send me a replacement. Genetics seem to be very strong. Can’t wait to sample each one of them.

  54. Verified Owner

    A real winner in my yard. I bought 10 seeds online and they were already in the mailbox one week later. They showed up in this bright golden packaging, had some very helpful tips on how to grow weed, and directed me to this website for further instruction. I have learned so much! I have never had this much success at growing anything, and now I am my own weed grower, how cool!

  55. Verified Owner

    Space Queen from Grower’s Choice Seeds was recommended to me by a friend, and I’m so glad I tried it! The germination process was easy, and the name truly represents its potency. This strain is a must-have in any collection.

  56. Verified Owner

    Great choice for those who love heavy indicas and to space out and chill. I am really thankful for the great looking bud, took me ALL summer to perfect but I’m just thankful for the great choices this website offers. You really don’t have to be an expert to get great weed. Just study up on the blogs and apply all your knowledge. It’s no harder than growing a tomato. So give it a try!

  57. Verified Owner

    Nice easy going high that lets you cruise with it to make for an enjoyable experience. This was well worth the time to grow since I got a heft yield size from it. Think this seed is very worth the time to grow and more gardeners should try it out.

  58. Verified Owner

    Had a really unique taste to it, almost like a berry flavor which was really nice. The high was good and hit me quick, lasted for quite a while which was great. I ended up with a good yield from these seeds as well.

  59. Verified Owner

    Space Queen is out of this world! Growing these plants was a blast, with their vibrant colors and strong branches. The high is truly cosmic – it gives you a burst of creative energy and a sense of euphoria. The flavor is a heavenly mix of citrus and fruity sweetness. Perfect for daytime use to combat anxiety and depression. A truly stellar strain!

  60. Verified Owner

    The Space Queen strain was a perfect balance of cerebral and body high, offering a really pleasant and enjoyable high. I felt really happy and relaxed after smoking it. My mood was uplifted and I had a great time chatting with friends. All around a really great strain, highly recommend it.

  61. Verified Owner

    Space Queen is the perfect strain for anyone looking for a balanced high. The citrus and fruity flavor is a nice bonus. The plants grow tall so make sure you have the space for them. Overall, a great choice for daytime use and managing anxiety and depression.

  62. Verified Owner

    Great purchase! Space queen is the perfect for an out-of-world escape sitting on your very own couch. Tastes sour and bright, easily makes me high, and usually lasts for ages. I can expect a full night of feeling nicely stoned from just 1 bowl. Helps that its over 20% THC!

  63. Verified Owner

    I am so happy to finally be smoking my own MJ…’s been a dream of mine for a long time. I prepped my ground, built up some good soil with good compost. It’s pretty awesome and great to have this weed just flourishing outdoors. It’s brilliant and beautiful, strong flavor and strong taste….the smoke can be pretty harsh, but I like the challenge 😉

  64. Verified Owner

    An amazing hybrid, a giddy smoke that tastes great with its amazing fruity earthy aromas. I really liked how the thc percent allows me to still go about my day without feeling completely sloth-like. Though growing was a bit of a pain, would not suggest this for new budding sprout growers.

  65. Verified Owner

    Space Queen is an impressive balanced hybrid strain that delivers a good high. It provides a unique experience with its combination of both body and head highs. Growing this strain was a great experience and the plants turned out beautiful.

  66. Verified Owner

    I smoked this strain and man, did I enjoy it. The high was really something special, uplifting my mood and making me feel as light as air. The plants I grew from these seeds were great, no dead seeds at all. Plus, the customer service was top-notch. And let’s not forget about the taste, it was absolutely delicious.

  67. Verified Owner

    The plants themselves required a bit of attention, but with intermediate gardening skills, they flourished beautifully.
