Trip Advisor… Just like its big sister, Auto Acid is a finely balanced hybrid (50/50 indica/sativa) which comes with all the power and taste of the original in a compact, easy to manage Autoflower form.

Auto Acid harnesses all the power of its feminized namesake, Acid, in an explosive Autoflower. Acid was released as a Paradise Seeds ‘new generation’ strain in the first decade of the 21st century. Auto Acid cannabis seeds produce a plant which Diesel fans looking for a quick and fruity finish with that distinctive acid taste will savor.

The original Acid was one of the first Paradise Seeds varieties which came with a twist on an existing popular strain. It enhanced the qualities of NYC Diesel, by adding some Dutch genetics into the mix to bring more stability, flavor and potency.

As such, this feminized plant was a natural choice when it came to developing the Paradise Seeds Autoflower collection and the outcome was Auto Acid. The addition of cannabis ruderalis genetics has produced this shorter stature plant with the in-built ticking body clock which sees it harvest a little after just 9 weeks from seed.

Like the name suggests, expect a bouquet and flavor that is unusually intense for an Autoflower variety – as is the taste which, in keeping with the Diesel tradition, has a reassuring sourness to it.

For the indoor grower, particularly those with limited height in their grow space, Auto Acid provides a good option.  Some growers recommend giving it an extra week under light to benefit from the full yield potential of this Automatic cannabis variety.

Auto Acid is also good news for outdoor growers in northern regions around the world where Auto Acid, like all Autos in the Paradise collection, will make the most of the strength of the midsummer sun and yield its payload in time for the summer holidays. However, the biggest prize will inevitably come for those sowing their Auto Acid cannabis seeds in southern regions where the warmth and the sun will swell those buds.

With its high calyx-to-leaf ratio, this plant is a delight to harvest. A pretty plant to look at, the bud growth is prolific and concentrated around the main stem.

The effect of Auto Acid is very much felt above the shoulders with a heady effect that can have a more mind expanding effect than other plants in the Paradise Seeds Autoflower collection and comes with a sense of nostalgic Diesel potency. Due to the psychoactive nature of this strain it is not recommended for users who are prone to anxiety.

This strain is not the most obvious choice for a medical user although Auto Acid comes with a general sense of uplifting relaxation which may appeal to medical users who are experienced with cannabis strains with high levels of THC.

Suitable for growing outside between 60º n.L. and 60º s.L., Auto Acid is ready to harvest 11 – 12 weeks after seed germination outdoors and 10 – 11 weeks indoors. Estimated yield is 400 g per m² indoors / 75 g per plant outdoors.
