Jack Diesel Auto is an autoflowering cannabis strain and the fastest version of NYC Diesel, one of the most famous strains developed by Soma Seeds.

NYC Diesel has its origins in the Big Apple, New York. It is a Sativa-dominant cross that combines Sour Diesel with an Afghani/Hawaiian hybrid.

In this automatic version we have chosen a selection of plants with more Sativa traits and faster flowering.

How to grow Jack Diesel Auto

It is a simple plant, with vigorous growth and a very discreet final height. It stays below 110 cm, a perfect size for balconies or terraces where it will not attract attention.

Autoflowering marijuana strains have a very short growing period of only 3-4 weeks. Opt for a large pot and a nutrient-rich substrate from day one to allow the plants to grow as much as possible before flowering begins.

In total, it will be harvested in about 8-9 weeks. Being so fast, it can be harvested up to 3 consecutive harvests outdoors during the spring and summer months.

Characteristics of Jack Diesel Auto

The buds are spectacular, big, hard as stones and covered with an unctuous layer of queen, very appropriate to make first class extracts.

The classic diesel aroma and flavor so typical of American hybrids dominates, but with intense touches of citrus such as grapefruit that makes a virtue of complexity.

The effects are powerful, energetic, creative and sociable, ideal for any time of the day and always better in good company.

In terms of yields and taking into account its discreet size, they can be considered very high. Outdoors you can expect up to 150 grams per plant in the larger ones. And indoors, with a 300-350 W LED, anyone will be able to produce 550 grams per m².
