White Widow from Greenhouse seeds is the strongest strain of marijuana on the plant. This baby got it’s name because it has an insane coating of tricomes that gives it a white appearance and this plant will bite you when smoked. The feminized seeds are a 60 percent indica, 40 percent sativa hybrid. White Widow’s THC content comes in at an impressive 25 percent, so you know we’re dealing with a high quality strain that will knock any smoker on their butt. Indoor methods are recommended for growing White Widow. It’s suggested to let this strain flower for 8 weeks, but if you really want this girl covered in a mass volume of crystals let her flower for 10 weeks. White Widow has a complex fruity flavor that is followed by a heavy buzz and should only be smoked by experienced professionals.
