Harlequin Bx4 by Reeferman

Charles "Reeferman" Scott did the medical community a massive favor when he put out Harlequin Bx4. The original clone-only Harlequin is a legendary CBD staple born from a wild mix of Colombian Gold, Thai, Swiss landrace, and Nepalese genetics. But passing clones around isn't always practical for the average grower. So Reeferman took that original mother and backcrossed it four generations deep to finally lock down that highly sought-after 1:1 THC to CBD ratio in a reliable seed form.
What makes the Bx4 so special is its rock-solid stability. Growers are consistently finding phenotypes that hit that sweet spot of 7% to 12% for both THC and CBD, with very little variation. In the room, it's a sativa-dominant plant that finishes up right around 8 to 9 weeks. You'll notice the buds are incredibly hairy, packed with orange pistils rather than the absurd blanket of white frost you see on modern hype strains. But don't let the bag appeal fool you—the medicine is in there. Just be careful not to take her too late; if you wait for heavy amber trichomes, the CBD starts degrading fast.
This isn't the stuff you smoke to get blasted out of your mind. Harlequin Bx4 is pure, functional medicine. The nose is a really interesting mix of musky earth, sweet overripe pineapples, and a background note that tastes just like old Nepalese blond hash. The effects are perfectly clear-headed and incredibly relaxing. It instantly washes away anxiety, muscle spasms, and joint pain without making your heart race or leaving you couch-locked. A lot of old heads run this specifically to make full-spectrum RSO, and honestly, it's hard to find a better strain for it.

Growing Harlequin Bx4: what to expect
As a sativa-leaning plant, plan for a big stretch after the flip (often 100–200%) — flip earlier than feels natural and keep training options ready. Sativa-leaning plants also generally prefer a lighter feed than heavy indicas. Growers familiar with Harlequin or Unknown Strain 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.
