SKU: NRVN-Black-Jack-Fem#14

BlackJack is thought of highly in the medical marijuana seeds scene.



BlackJack’s mother, Black Domino, was a clone of a marijuana plant sent to the Netherlands from the area around Seattle. Its father is Nirvana’s very own Jock Horror. Nirvana BlackJack produces hard buds with huge, grape-like calyxes that are completely encrusted with THC! The smoke is heavy and flavoursome, and produces an exceptionally long-lasting high.

  1. 3 weeks into veg Review by Linda

    Was hoping to take clones by now but she is staying short with very close nodes. The bottom nodes are going to catch up to the top by next week. Will take clones at that point and hopefully flower in 3 weeks. Will keep updating. (Posted on 12/18/2015)

Payment Advice

We are based in the United Kingdom and we accept worldwide orders. If you are not based in the UK it is possible your card provider or bank may flag your order as a possible fraud transaction. If you have any issues when attempting to checkout, this may be the case. To fix this just call your bank or card provider and tell them you are trying to purchase a souvenir form a UK based online shop.


When you receive your credit card statement you may see a payment from a random merchant, which will be for your order. We often use this to keep you order stealth. If you are unsure of a transaction on your credit or debit card statement please contact our dedicated support team.


We have found that payments with p.o. boxes as billing addresses and purchases with pre-paid cards are often used by fraudsters. For this reason it is highly likely we will cancel your order if you do not provide a real address and your real bank card. We also cancel ALL orders made via proxy. We understand you'd like to protect your identity, this is why we do not share any information with any third parties.
