Auto Speed Haze feminized seeds

Speed Haze from Black Skull was already a very fast Sativa but they wanted to deliver a haze that could be planted outdoors and also have it in flower and finished long before Autumn. It took many generations and selections to get the Speed Haze 100% autoflowering but it was finally done and Black Skull are very pleased with the results.

Black Skull Auto Speed Haze Autoflowering Feminised Seeds Info

Auto Speed Haze can easily reach 1 metre in height and demonstrates haze characteristics such as fine leaves and long buds but the final effect is not totally sativa. There is still much indica and ruderalis in the genetic makeup, which means Auto Speed Haze still has quite a narcotic effect.

Although 100% autoflowering, she will take a little longer to flower (21-25 days) and will need about 70-80 days from seed to finish. During the flowering period you will be overjoyed with the typical hazy fragrances of pepper and pine and towards the end of the flowering period the buds will be shining with crystals.

The flavour includes sharp citrus tastes along with earthy undertones and once the spicy smoke fills your lungs the effects are almost immediate giving a soaring cerebral high that is unmatched by any other autoflowering strain.
