We have crossed-bred our Black Domina with an exceptional Jack Herer of pleasing and intense aroma similar to the haze’s cathedral incense. The result is one of our most powerful and productive plant.

This variety produces long side branches and plenty of abundant resinous buds, giving the plant a shape similar to a sphere. This cross provides the plant a sweet aroma characteristic of Black Domina that softens the deep incense aroma of our Jack. It features the great vigor of a hybrid, totally adapted to indoor conditions. Planted outdoor directly in the ground and with enough sunlight it becomes a resinous and hairy monster of about 3 meters of height.

Sweet Seeds are a seed bank from Spain who specialise in feminised cannabis seeds. After conquering Spain with their now world renowned seeds they moved to conquer the whole of Europe. They listen to both the cultivator and the public together, enabling them to combine seeds to offer unique packages at affordable prices.

Being one of the first seed banks to offer autoflowering varieties, Sweet Seeds used their knowledge and experience in growing to put a spin on what most seed banks offer – an approach which is now racking up competitions and prizes.

Sweet Seeds breeding philosophy is simple: they put their view of being a collector and consumer of genetics first and in doing so collect as many best genetics as possible and store them for an unlimited time.

The selection of their plants is based on the plants qualities themselves and not the history or origin of the plants. With these values in place they use both traditional and modern breeding techniques to create 99.9% of female plants. In addition to this they are currently developing brand new varieties of feminised autoflowering plants.

Sweet Seeds believe that cannabis is a gift from nature which anyone should be able to enjoy and develop. The best quality genetics should be shared and improved as this is the best way to conserve a cannabis variety. Buy Sweet Seeds right here at Seedsman now.
