Blue Widow Weed Strain UK is a cross between Blueberry and White Widow that provides consumers with both uplifting and calming effects. This flower will have a strong, sweet aroma that may also include sour citrus or pine. The buds can be colorful, with tints of blue and purple, and should have a coat of long orange hairs. Blue Widow plays against type, growing taller than most indicas and providing more mental, heady effects. In higher doses, the blissful relaxation this strain provides may lead to drowsiness and help you get to sleep.
