Jacky White

Fast Finish, High Yield Sativa

Jacky White is a sativa strain from the Paradise Seeds classic collection. Its popularity is the result of its status as a fast finish, high yield sativa with a sweet citrus/hazey taste. With a predicted harvest weight of 500g per m² indoors / 750g per plant outdoors, two legendary strains underpin its genetic core – Jack Herer and White Widow.

It is advertised as a good choice for indoor and outdoor growers alike, with a 60 day flowering time in the grow room (with a mid October finish outside in the northern hemisphere). Jacky White feminized seeds were put to the test 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”.

Harvest Yield

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.

Verdict

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.
