White Rhino strain is a hybrid of White Widow and an unknown North American indica strain, creating a bushy and stout plant. The buds give off a strong and heady high. Like many Indica dominant strains, this one should be used in the evening or at night and can be rather effective at treating insomnia. The numbing effects on the body are sought after by patients suffering from chronic aches and pains. Others choose the strain to relieve stress, anxiety, nausea, migraines and induce appetite.
