About Royal Madre
Royal Madre traces its lineage to a cross of Jack the Ripper and Critical+, and the version cataloged here is the one offered by Royal Queen. It's a hybrid split 60 percent sativa to 40 percent indica, with THC results running roughly 18 to 20 percent, reaching right up toward that upper line by harvest. In the garden it's rated a moderate challenge, finishing its flower cycle in 9 weeks — a fairly quick turnaround for a sativa-leaning plant. Indoors it stays compact, reaching 90 to 140 centimeters and returning 450 to 500 grams per square meter, while outdoors it stretches taller, up to 200 centimeters, and rewards that extra space with 550 to 600 grams per plant. That combination of documented parentage, a short-for-its-type flowering window, and yields that scale well whether grown in a tent or a garden bed makes Royal Madre a genuinely well-documented option among hybrids.
