Nirvana White Castle is an F1 marijuana hybrid of two absolute winners. With a White Widow mother and our award-winning Ice for a father, White Castle marijuana seeds are as outrageous as one would expect. The sturdier, denser structure of Ice really thickens up the often light and wispy White Widow buds. White Widow's flavour, strength, and social high remain very present in this cannabis strain. Medical marijuana users are extremely fond of White Castle for its pain-killing properties.
