Original Jack Herer Auto carries the name of the famous cannabis activist and the energetic character of the strain that honors him. Fast Buds crossed the classic Jack Herer with Fast Buds Auto #1 and refined the line to a stable F4 feminized autoflower, aiming to keep the clear-headed effect while boosting resin, structure, and autoflowering reliability.
It is a key part of Fast Buds’ Originals line, the series of legendary strains reworked as autos. Run it on 18/6 or 20/4 from start to finish and it is ready in about 9 weeks. No light change is needed.
Fast Buds rates it XL at 70-110 cm (27-43 in). Even at this size it delivers 400-500 g/m² (1.3-1.6 oz/ft²) indoors and 60-150 g (2-5 oz) per plant outdoors.
Even Branching and High-Grade Resin
Side branches fill out evenly from top to bottom, so the plant produces many well-formed colas instead of one big top and a few small ones. LST helps open the center and gets light to every site.
The buds are long and well-filled, with swollen calyxes buried under thick trichome cover. Fast Buds highlights the quantity and quality of the resin, which makes this a strong choice for hash makers who care about flavor as much as yield.
Start it in the final container, keep nutrients moderate, and guide the branches outward during weeks three and four. The plant handles commercial-scale runs as well as single home grows.
Spicy Citrus Taste and a Balanced Lift
The flavor is sharp and classic: earthy sweetness with lemon, black pepper, and light spice. The same terpene mix carries over into concentrates, which come out clean and aromatic.
Customer feedback puts happiness and energy at the front, with creativity and a calm undertone close behind. Fast Buds notes that the high stays centered and pleasant rather than overpowering, which makes it a good pick for lighter users or for daytime sessions.
