Jack Flash — Sensi Seeds

Seb's take

Seb Silverback

A Cannabis Cup winner from Sensi Seeds, splitting Sativa and Indica almost down the middle for a euphoric high with none of the usual trade-offs. Citrus, lemon and earthy wood on the nose; natural resistance to mould and fungi makes her a sound outdoor choice. Regular seeds, for growers minded to breed their own.

Growing Jack Flash: what to expect

Regular seed: roughly half will be male, and the males must go before they find the females. One for growers with sexing in their skillset — or the willingness to acquire it.

Expect around 9 weeks in flower — textbook timing. Textbooks, for once, being useful: here's ours.

Potency sits in the milder band — 17% THC on the breeder's sheet. No embellishment from us; the figure is the figure.

The aroma is citrus-forward: zest first, everything else in its wake.

The dominant note in the reviews is uplifting; daytime company, by most accounts.
