Amnesia Haze Feminized Seeds Overview

8 out of 10

Royal Queen Seeds (RQS) developed this two time Cannabis Cup winner by crossing a Haze hybrid back with an original Haze. The result is a robust sativa dominant hybrid strain that produces high yields of potent bud. Flowering takes a whopping 12 weeks, but the top-shelf flower is worth the wait.

The Details

We’ve grown several of these and each seed germinated successfully. Due to the sativa dominance, they can get a little leggy if left to grow so we topped each once and performed low stress training to get a flat canopy. They responded well to training and maintained a moderate height.

The flowers were medium sized with good resin production and had a fruity aroma followed by a hint of spice. We saw consistent flowering times of 80 days to get a balanced effect at harvest.

Measured at 22% THC, this bud packs a punch. The medium levels of CBD smooth the effects, so we didn’t note anxiety or any other negative effects and found it to be generally medically beneficial.

Easy to Grow?

These plants were easy to grow, since they weren’t particularly prone to pests or nutrient issues and responded well to topping and training.

Speed to Flower?

The breeder recommends over 12 weeks – 84 days – which will result in potent buds with strong effects. The flowers were medium sized but numerous and dense with medium resin production.

Medical Use?

Amnesia Haze produces relaxing effects, making it a a good choice for treating anxiety, stress and depression. If harvested at around 80 days, the high is energentic and doesn’t cause couchlock effects. Left in flower for more than 85 days, the CBD production increases to medium and improves the overall medical effects. Learn more on how to find the perfect time to harvest in our harvesting guide.

Amnesia Haze is easy to grow and has great medical and recreational effects.


Amnesia Haze has high levels of THC, resulting in a strong but stimulating high. The effects are uplifting and stimulating, common in sativa dominant strains.


The advertised yield is very high, at over 600 grams per square meter, but we weren’t able to duplicate that type of yield. Growing under 800 watt LED lights, we recorded a respectable 450 grams per square meter.

The buds were medium sized and dense with medium levels of resin development. The overall yield was on par with other strains.


Amnesia Haze has a nice fruity flavor that is followed by spicy or herbal flavors. The flowers cure well and results in a relatively smooth smoke.

Grow Setup

We grew in a 4×4 tent with 4 LED lights: one 1200W light, one 800W light and 2 400W COB lights. The temp was between 60 and 70 degrees thoughout the grow. We grew in a soil/coco mix and used Blue Planet Nutrients as the base nutrient for this grow. Once per week, we added CalMag and compost tea.
