Strain Review: Flash Automatic by Kannabia Seeds


This was Kannabia’s first cross with the ruderalis subspecies, after a selection process in search of higher yield and more flavor.

Crossing with White Domina has made Flash more stable, and the Afghan phenotype provides a more robust shape (highly resistant to pests) and deep psychoactivity.

When working with autoflowering varieties you should be aware that they need a lot of light from the first transplant on. Kannabia recommends over 18 hours with an energy supply adapted to the recommended maximum for the specific growing area. We recommend using an aerated substrate to encourage optimal root development, growing in pots 5-10 litres in volume, in order to get the best from your plant indoors. The looser and more aerated the substrate is, the more the plant will grow in a shorter time. (A hydroponic system is the most suitable to assure the best results with this variety.)

It adapts well to all conditions, and we recommend growing outdoors in spring, summer and autumn (although the results are best in the summer). The plant will grow to 35-55cm. It is a very easy variety to grow, ready within 7-8 weeks of flowering.

Crossing with White Domina has given it a sweetish flavor when lit and fairly high psychoactivity for an autoflowering variety.

The cross can also be noted in the yield, which should be around 35-70 grams per plant.
