Space Queen by B.C.G.A.

If you were growing craft seeds in the early 2000s, you already know the absolute legend of Space Queen. This was the ultimate collaboration between Vic High of the British Columbia Growers Association (B.C.G.A.) and MrSoul over at Brothers Grimm. Vic took his notoriously potent Romulan female clone and dusted her with a pineapple-leaning Cinderella 99 male from Grimm's camp. The resulting cross was mind-blowing, but the original B.C.G.A. seed lines went extinct years ago. Thankfully, the impact of this cross was so massive that it essentially became the backbone of an entire generation of craft genetics.
You can't talk about Space Queen without bringing up Subcool and TGA Genetics. Subcool found a killer male in those original seeds he dubbed "Space Dude," and he basically built his entire seed bank around it. He crossed that male to everything, birthing heavy-hitters like Jillybean, Chernobyl, and Agent Orange. Of course, if you dig into the old ICMag threads, there's always been some drama about Subcool allegedly downplaying Vic High's original work. Regardless of the forum politics, the fact remains that the Romulan and C99 pairing was lightning in a bottle.
In the garden, Space Queen is a wildly vigorous plant that demands respect. She throws out massive, resin-coated colas that get so heavy they will literally snap the branches if you don't trellis them properly. Most growers run her in a SCROG just to handle the weight. The terpene profile is straight candy shop funk—a loud, offensive mix of sharp lemon, vanilla, and rotting fruit. It hits incredibly hard with a fast, racy head high that eventually settles into a deep body stone. For breeders and hash makers alike, those original F1s were the holy grail, and modern recreations are still chasing that perfect B.C.G.A. magic.

Growing Space Queen: what to expect
As an indica-leaning plant, expect a modest stretch after the flip (roughly 50–100%) and dense bud structure — which makes late-flower humidity discipline the main risk: keep RH in the 40s once buds fatten to stay ahead of mold. Growers familiar with Romulan or Cinderella 99 will recognize much of its behavior. Whatever the listing says, the cut in YOUR tent is the ground truth: log feedings, readings, and photos, and let the trends — not the label — drive decisions.
