Critical Bilbo XXL Autoflowering - Black Elephant Genetics

Critical Bilbo XXL Auto: the yield of the Critical family in autoflowering form

Critical Bilbo XXL (Auto French Lines) by Black Elephant Genetics carries in its name the Critical family, one of the most productive in European growing, and Critical Bilbo, the Basque Country selection prized for its speed and intense aroma. In this autoflowering version it is a balanced hybrid that flowers in 8 weeks, reaches 550 g/m² indoors and gives off a citrus, sweet and fruity profile. The XXL tag is no accident: it is one of the most generous autoflowering strains in our catalogue.

Why choose Critical Bilbo XXL Auto

✓ Autoflowering: flowers on its own, no photoperiod change needed.
✓ 8-week flowering: a short, predictable flowering phase.
✓ Balanced hybrid: a manageable structure with dense, heavy flowers.
✓ XXL yield: 550 g/m² indoors.
✓ Citrus aroma: sweet and fruity, with a fresh background.

Indoor cultivation

Develops a vigorous plant with long side branches that fill with dense flowers during its 8 weeks of flowering, yielding 550 g/m² indoors. Sow it directly in its final pot to avoid transplant stress, feed it lightly during the first weeks and keep the same light schedule throughout. We recommend a high-quality airy substrate such as coco coir and regular pH control (6.0-6.5 in soil). Instead of topping, gentle LST helps spread the light across the branches, and stakes or a net help support them as the flowers gain weight.

Outdoor cultivation

Outdoors it is just as easy to grow. Plant it in large pots or directly in the ground with an airy substrate, in a sunny, well-ventilated spot. As it does not depend on the photoperiod, it flowers on its own whatever the day length, allowing staggered sowings throughout the warm season. Its loaded branches appreciate simple support in the final stretch.

Aroma and flavour

A lively, sweet profile: bright citrus notes of lemon and orange over a sweet, fruity base reminiscent of ripe fruit, with the slightly earthy background typical of the Critical family. An intense aroma that peaks in the final weeks of flowering, so an activated carbon filter is advisable indoors.

Frequently asked questions

Do I need to change the photoperiod for it to flower?
No. Being autoflowering, it switches to flowering on its own and completes that phase in 8 weeks. You can keep the same light schedule from start to finish.

Does it need stakes?
It is advisable. Its side branches fill with dense flowers and can bend at the end of flowering; stakes or a simple net keep them upright and well exposed to the light.

How should I store them until sowing?
In a cool, dry and dark place, ideally in the fridge inside an airtight container. This preserves their germination power for a long time.
