Zéclair BX1 by Umami Seed Co.

A cut Umami kept close - now ready for your grow.

Only around 45 packs of the original Zéclair seed drop were released. Umami developed the BX1 to reinforce Zéclair’s candy traits and push its funky gas further. A personal favourite and daily driver for the breeder, the original BX1 breeder cut is now available exclusively through Alpine in a limited, individually numbered release.

Earthy Kush and chocolate gas meet vanilla frosting, toffee and saltwater taffy, with the classic punch of OG.

Cultivation profile

Zéclair BX1 is a vigorous hybrid with strong lateral branching and the potential to stretch by up to 200% during flowering. It produces medium-sized, rosebud-shaped flowers with dense trichome coverage and deep purple-to-green hues. Plants respond especially well to early pruning and topping.
