Fast Buds


Founded in sunny California in 2010, FastBuds set out to revolutionize autoflowering genetics—and they’ve more than succeeded. What began as a mission to enhance speed and simplicity in cannabis growing has evolved into a global movement. Today, FastBuds is a multinational team of passionate breeders creating cutting-edge autos with massive yields, sky-high THC levels, and exceptional terpene profiles.

Their strains are designed for both newcomers and experts, with stable, easy-growing plants that finish quickly without compromising quality. Many cultivators prize FastBuds genetics for extraction, thanks to their sticky, resin-rich flowers ideal for concentrates like hash and rosin.

Despite their worldwide reach, FastBuds keeps its Californian DNA at the core of its breeding program—delivering premium American genetics to growers across the globe. Overgrow is proud to offer South African growers access to this next generation of autoflower excellence.

This indica-dominant, autoflowering hybrid by Fast Buds brings you all that coveted Runtz quality in compact auto form. It boasts plenty of bag appeal, massive auto yields, easy-growing genetics, plus bags of flavour and mammoth THC levels.

These auto cannabis seeds can grow up to 1.3m tall, offering all the Runtz qualities for which this strain is loved in California and worldwide. Very bushy appearance with large fan leaves and many side branches that pack on the colas.

Heavy yields provide all of the quality in a fraction of the time – incredibly dense, dank, juicy nugs with orange hairs and a spear-shaped appearance. Flowers are frankly fit for royalty.

Forbidden Runtz Auto delivers a scrumptious, mouth-watering blend of flavours and aromas that combines earthiness and sweet fruit. A creamy smooth smoke with some delicate citrusy undertones.

Monstrous THC levels of up to 26% will hit you right between the eyes – cerebral, uplifting sensations blended beautifully into relaxation that will delight even the most experienced connoisseurs. Great for socialising at first – just not too far from home for the relaxation phase – or binging a series.

Grows with ease indoors, in a greenhouse, or outdoors – Forbidden Runtz Auto will thrive with just basic care. Plant straight into around 20L pots of coco coir or a light cannabis soil mix. Water lightly but frequently. The heavy branches packed with fat buds may need tying up or staking.
