White Castle Regular Seeds

£ 13.99


White Castle from Nirvana seeds is an F1 hybrid of White Widow and Nirvana Ice so its no surprise that this cannabis strain is covered in frosty THC crystals. Nirvana seeds white castle is a very sturdy cannabis strain with solid buds and an earthy hashlike aroma. White castle plants produce medical marijuana of the highest quality which can aid pain, insomnia and anxiety.

Nirvana White Castle is an F1 marijuana hybrid of two absolute winners. With a White Widow mother and Nirvana’s 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.
