About Rocklock
Biker Kush V1 and Grapefruit Romulan cross to make Rocklock, an 80 percent indica that DNA Genetics offers through its GYO line. The grow is rated moderate, with plants topping out at 80 to 120 centimeters indoors and rewarding that manageable footprint with a strong 500 to 600 grams per square meter. Flowering takes eight to nine weeks, a standard window for a cross this potent, and THC lands high, between roughly 19 and 22 percent. No effects, flavors, terpenes, or medical uses have been documented for this specific listing, leaving genetics, growth habit, and potency as the confirmed data points. The Grapefruit Romulan side of the lineage suggests citrus genetics feeding into an otherwise Kush-heavy background, though nothing in the record confirms how that combination actually presents in flavor or effect. What's certain is a compact, high-yielding indica with serious lab-tested strength behind it.
