About Grand OG F4 Feminized Seeds

Grand OG F4 Feminized Seeds is a Low (0-1%) CBD strain with True OG X White Widow genetics of the Feminized variety brought to you by ROOR Seeds


Grand OG from Roor is an indica-dominant strain of marijuana which represents a fusion of the very best of new and old skool genetics.  True OG is one of a handful of special OG Kush cannabis strains with mysterious origins possibly dating back to a Grateful Dead concert in the 1990's.  Perhaps we'll never know for sure where The True came from, but we're sure glad it's around now.  White Widow surely needs no introduction - she is an enduring favourite in the coffee shops of Amsterdam and has been for several decades.

Roor have pulled out all the stops with this new range of feminized cannabis seeds and strains like Grand OG show that their efforts have not been in vain.  

Grand OG exhibits the very best characteristics from both parent strains - the unbridled power from the True OG side is perfectly complemented by the stability, vigour and trichome production of the White Widow genetics to produce an indica-dominant marijuana variety for the true connoisseur. 

Despite this being an indica dominant strain, Roor's test grows of the Grand OG - conducted in their legal environment in The Netherlands - showed strong, healthy plants with a tall, stocky stature, atypical to many indica varieties.

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.
