Jacky White is a high-yielding, fast-finishing sativa-dominant hybrid that combines legendary genetics with exceptional performance. This strain is celebrated for its vigorous growth, resilience, and ability to deliver potent effects alongside a rich citrus terpene profile. With a flowering time of 8–9 weeks indoors and a harvest window in mid-October outdoors, Jacky White produces up to 500 g per m² indoors and 750 g per plant outdoors.
Lineage
Jacky White is a cross between White Widow x Jack Herer. The White Widow genetics provide stability, resin production, and a dense trichome coating, while the Jack Herer lineage contributes creative clarity and an energetic cerebral high. This combination results in a well-balanced sativa hybrid with exceptional growth potential.
Aromas, Flavour and Effect
Jacky White is a terpene-rich variety dominated by Limonene, Pinene, and Myrcene, producing an intense citrus aroma with distinct grapefruit undertones. The scent is vibrant in the grow space, and once dried, the buds retain a sweet, fruity character with a pronounced citrus flavor that lingers on the palate.
The effects lean towards the sativa spectrum, delivering an uplifting and energetic high that enhances creativity and focus. The initial rush of euphoria is complemented by a gentle indica undertone, providing a sense of relaxation without sedation. This strain is well-suited for daytime use, social settings, and artistic pursuits.
Jacky White is favored by medical users for its uplifting effects, making it a beneficial choice for managing stress, depression, and fatigue. The strain’s ability to boost energy levels and mental clarity can help counteract symptoms of lethargy and low motivation.
Cultivation
Indoors, Jacky White exhibits vigorous vertical and lateral growth, with strong side branches that support long, resinous colas. Growers with height limitations may need to employ pruning or training techniques to manage its stretch. Highly stable and consistent, this strain performs exceptionally well in controlled environments.
Indoor Yield: 500 g per m²
Outdoors, Jacky White thrives in both temperate and Mediterranean climates. Its natural resistance to pests and mold makes it an excellent choice for outdoor growers seeking a reliable and resilient sativa. Given ample space and sunlight, this strain can develop into a large, high-yielding plant with dense, trichome-rich buds.
Outdoor Yield: 750 g per plant
Grow Report
Below is a detailed grow report of this strain tested by Expert grower, Mr. Power Planter.
Germination and Vegetative Stage
Seven Jacky White seeds were sown, all of them sprouting without any problems. The seedlings were put into 6 litre pots filled with Plagron Royalty Mix and placed under a MaxGrow 180 watts Dual Spectrum CFL, being exposed to a daily light cycle of 18 hours. They spent three weeks in the vegetative stage, growing healthy and homogeneously. Then Mr. Power-Planter induced flowering by switching the light cycle to 12 hours per day, replacing the CFL by an Osram NAV-T 600 watts lamp. Within 7-9 days, by forming small preflowers at the main stem.
Flowering Stage
The plants had developed relatively strong side-branching and kept on stretching a lot in the course of flowering, a behaviour that indicated a good deal of sativa genetics. That stretching behaviour led to fairly wide internodes, but the very compact, dense and roundish structure and size of the Jacky White buds could well compensate for this.
The calyx-to-leaf ratio was quite high with most of the plants. They produced more and more resin in the course of flowering and in the end really lived up to the expectations raised by their strain name Jacky White, exhibiting lovely thick white layers of resin. The aroma of the Jacky White plants was quite a surprise, giving off an incredibly strong and delicious grapefruit scent.
After 61 days of flowering, Mr. Power-Planter harvested all of the plants, although only three were fully ripe, the other four would have needed another week or so, a little bit later than stated by Paradise Seeds (60 days). But that difference was only marginal. With end heights of 83, 89, 99, 101, 101, 104 and 105 cm, the uniformity of the seven Jacky White plants was very satisfying, confirming Paradise Seeds` description “this mostly sativa hybrid is also notable for her stability, with only slight variations between individual plants”.
Five plants delivered between 33 and 38 dry grams of finest sinsemilla, the yield of the other two (the shortest plants) was just below 30 grams – on the whole, for plants grown from seed, the harvest was clearly above average. According to Paradise Seeds, under optimum conditions even 600 grams per m2 are possible with Jacky White. They also say that pruning or bending to increase yield works well with this strain.
Smell and Smoke Report
When it came to test smoking, we were highly delighted by the strong and fresh sativa turn of the Jacky White buds. The intense citrus taste rushed into our mouth while, just as fresh and highly energising, the THC molecules took possession of our brain twists. After a while, however, that soaring sativa high changed into a more stoney high that was enjoyable, too.
Mr. Power-Planter was extremely satisfied with his fruitful Jacky White grow, being totally captivated by these full blooded ladies. He highly appreciated the fact that all of the seven plants turned out to be 100% female and was taken with the great Jacky White citrous flavour and high. Jacky White can also be grown outdoors successfully in a moderate to sunny climate, ripening by mid October.

Great Smoke
funny how you always remember those really great smokes you had , they stay with you all through your life as a kind of yardstick that all others are measured against. .the yardstick in this case is some durban poison, obtained by a freind of a freind from the back streets of soweto sometime in the early 80’s .
ahhh those were they days. well they were for me, used to get some really nice hash back then and everything that came this way was grown outside under the sun. Things have changed a lot since then theres 2 other times i thought man that was some killer smoke.
some white widow that leveled a room full of musicians. to the point of hysterical insane laughter for hours and some super silver haze that made me wanna write an entire album and a novel at the same time as being in star trek for real …. so thats 3 memorable strains in 30 something years of smoking. Jacky white is number 4 a great smoke. Very uplifting. no fatigue, just the way i like it 😉 and the flavour is fantastic. takes me back a few years to when the white strains were all the rage so congrats you guys . you made it on to THE LIST. killer smoke and well worth the years of effort in my humble opinion. Thanks for doing that.
