Platinum OG is known as a heavy hitter, bred by Mendocino Farms to be just that. They combined Master Kush and OG Kush into a strain that’s anything but delicate. Some researchers suspect that there’s some Mendocino Purps in there as well. Platinum OG grows best outside, particularly in sunny, warm climates, and flowers in 63 days, give or take. The strain’s hardiness makes it resistant to diseases, mold, and mildew, which makes it friendlier for novice growers, especially those in humid climates. The plant itself develops into a shade of light silver-platinum beneath a coat of resin and crystals, concealing purple tones and orange hairs.
