Dinafem chose their two best clones of White Widow and Haze and crossed them, likely using the colloidial silver sex-reversal process in order to create male flowers on female plants, thus producing feminized seed stock. White Widow is known for its power and trichome production, well Haze is renowned for its soaring, cerebral effect — combining the two produces a Sativa-dominant plant which ups the frostiness of the Haze, lessens the flowering time, but still retains much of the Haze flavor and aroma.
Like a sweet Haze, carrying notes of flowers, citrus, vanilla, and tropical fruits — very appealing.
Flowery (even soapy), the Haze seems to come through more clearly in the flavor than the smell — it's not quite as sweet but still carries the same "smooth" qualities of vanilla and eucalyptus.
With a typical rush of Sativa effects starting things off (lots of eye/head/face pressure, a marked increase in heart rate), the Haze part of the equation announces itself quickly. Very cerebral, even influencing vision a bit, this strain takes the user on a bit of a mental ride early on. After the initial effects die off about 1 hour into the experience, it shifts gears, apparently bringing more of the White Widow influence to the table — a floaty, relaxed state that could easily lead into sleep finished things off. This strain is recommended highly for its "up then down" experience as an evening med, as it will leave the user relaxed and ready for sleep after about 3 hours.
There are two common phenotypes in Moby Dick, one that is heavily Sativa-dominant and carries more of the spicy, floral, incense Haze taste and smell. The other pheno has slightly more Indica influence and the final product is sweeter. Dinafem recommends keeping the pH below 6.5 at all times to avoid iron deficiencies and keeping the EC around 1.5 - 2, as it it a rather heavy feeder and generally gets large.
