White Widow XTRM seeds

White Widow XTRM seeds – that’s White Widow Extreme!

white widow xtrm seedsThey thought that the famous White Widow marijuana was as good as it could get – and then we produced the White Widow XTRM seeds – a refinement of the traditional favourite of Amsterdam coffee houses, White Widow.

White Widow XTRM contains all the qualities of White Widow that made it great, but through years of selective breeding we have produced a “White Widow on steroids”.

White Widow XTRM seeds tend to grow faster with greater vigour resulting in larger harvests of more potent THC-glistening buds – up to 500 grams per square metre of growing space.

You got the space? We’ve got the strain to blow your socks off.

Growing to an average height of 50 cm indoors, these stocky plants enjoy an average flowering cycle of 7 to 8 weeks by which time a bountiful harvest is ready to be cut, dried, and sampled 😉 .

White Widow XTRM may not be as stable as the original White Widow strain, but for those of us who like to be on the cutting edge of marijuana cultivation, this is a strain that’s worth a little gamble.

Of course you can stick with a ‘safe bet’ of regular White Widow seeds or White Widow feminised seeds, but if you want to take a chance in growing a crop your friends will be talking about for years to come then White Widow XTRM seeds are your best bet.

Also, like regular White Widow, White Widow XTRM is a potent medicine. Used in smallish doses, it can relieve stress, anxiety, PTSD and depression. Used more heavily, it can ease chronic pain. In fact, the greater potency of White Widow XTRM makes it ideal for pain relief. Inhale and breathe easy 🙂
