The potency is one of the strongest to come from a South American strain and consumers have been enthralled with the top-shelf quality of Rio Negro.
Flowering time, when grown indoors, should be right around 10 or 11 weeks, while outdoor gardeners in the Northern Hemisphere will likely see a harvest by early to mid-October. Rio Negro is a fine specimen that won't need too much attention to successfully put out a quality harvest. Yields are moderate, but the potency is off the charts. This is a tall, vigorous variety, so indoor gardeners should limit the time in vegetation to just two weeks or so.
