The “Amnesia” part of the name refers to the Amnesia Haze parentage, from which Ultra White Amnesia inherits its 22% average THC. This definitely brings it under the heading of “high-THC strains” and if you’ve only ever tried Indicas before, you’ll notice quite a difference. What’s particularly interesting about Ultra White Amnesia is that the overall effect combines the uplifting and energetic effects of a Haze the solidity of the White Widow side, which serves to steady the high and ensure that the effects are felt in the body as well as the head. As an added bonus, the fact that the high does remain grounded, means that the transition to the body stone is nicely gentle. This means that although Ultra White Amnesia is arguably more of a day strain, we could see it being used at night too.
In terms of straightforward numbers, yields are pretty decent. Indoors you’re looking at 480 gr/m2 and outdoors you can get up to 500 gr/ plant. It does, however, have to be said that Ultra White Amnesia has a lot of Haze (read Sativa) genetics, which means it likes to stretch and that these days you can get similar yields from much more compact varieties, although you’d probably have to accept lower THC levels. You also have to remember that the Haze family has a bit of a reputation for being both greedy and fussy and frankly, we’d say there was a fair bit of truth in both comments. Ultra White Amnesia certainly likes its food and you’re going to have to be prepared to give it the nutrients it needs to grow (and yield) without going over the score and killing with kindness. Likewise, you’re going to have to stay on top of your standard growing basics (like ventilation) because Ultra White Amnesia just does not forgive mistakes the way some other strains do.
Auto White Amnesia flowers in 9 weeks, which is longer than most Indicas, but still on the quick side for a strain with such a high percentage of Sativa genetics. You have the White Widow parentage to thank for this. This means that outdoors you’ll harvest towards the latter end of September, so if you live in northern Europe you might want to think a little before deciding if Ultra White Amnesia is really suitable for you. Greenhouse growing could be a reasonable compromise.
The taste is definitely from the Haze side rather than the White Widow side. It has an earth base, with a fruity body and some sweet top notes, some people say floral. The aroma is definitely on the sweeter, more floral side.
Both of Ultra White Amnesia’s parents look good in a bag, so it’s little wonder Ultra White Amnesia does too. The White Widow genetics means the buds are thicker and heftier than you’d expect from a Sativa and they’re absolutely loaded with sticky resin crystals. These nugs are definitely one for the grinder rather than your fingers. Throw in a generous sprinkling of orange pistils and you have a very attractive result.
The Haze family continues to thrive because it offers such a great, happy, clear, energetic high that there are still plenty of people think they’re worth the effort of growing. If you’re one of them then Ultra White Amnesia definitely deserves at least a look, since it is on the easier side of the Haze strains. If you’re a beginner, however, we suggest you wait until you’ve successfully grown photoperiod Indicas before you tackle Ultra White Amnesia.
