Cheap Seeds Jackberry Cannabis seeds Feminized

Genetics & strain profile

Jackberry is a cross of Jack Herer and Blueberry, a mostly sativa hybrid with 21% THC and low CBD, easy to moderate to grow, with a harvest from September and two grower diaries on GrowDiaries. This listing is the cheap-seeds version: we sell it at a lower price because some autoflower seeds of the same strain were accidentally mixed in, so your pack may contain a few autoflowers, or none at all. Its three reviews, averaging 2.7 out of 5, are all about exactly that. One buyer’s plants were all autos and small, though every seed germinated; another had four survivors, all autos, and still called it worth the chance at the price; the third found a single auto that flowered about two months into 24-hour light and is now full of colas on a plant about two feet tall. If you want only photoperiod plants, buy a standard pack instead. Seeds that do not germinate are guaranteed.

How Cheap Seeds Jackberry grows

Plan for two kinds of plant. The photoperiod ones flower in 60 to 70 days after the switch to 12/12 and can give up to 400 g/m² indoors; outdoors they are typically ready in early October, with up to 500 g per plant under optimal conditions. The autoflowers, on the reviews’ evidence, stay short and finish on their own, and one reviewer’s auto began budding under 24-hour light, so do not wait for a flip that will not come. The practical answer is to grow the pack under a schedule that suits both — such as 18/6 — and sort the plants at about four weeks: any that are already showing flowers are autos; keep them apart, give them the same feed and harvest each by its own trichomes. Mixing both in one tent is fine if you track them. For pure photoperiod plants, choose a standard pack. If something looks wrong, contact us.

Taste, aroma and effect

Sweet and fruity, with the berry flavour of Blueberry over a Jack Herer base. The effect is a clear-headed mental buzz with gentle physical relaxation, a daytime strain that stays functional. For a standard pack, see Jack Herer or Blueberry; for the autoflower side, Jack Herer Autoflower; and for another discounted pack, Cheap Seeds Gelato x Granddaddy Purple.
