Basic Information About Amnesia Haze

It's quick to give you a trippy high effect. While its name may indicate loss of memory, this strain vows to actually help users create some really cool memories. It has won for Best Sativa twice, at the Cannabis Cups in 2004 and 2012. 

Genetic lineage: It's 70% sativa and 30% Indica. Soma's Amnesia Haze goes back to the early 2000s. The award-winning cannabis strain combines Laotian, Jamaican, and Hawaiian sativa varieties.

Medical uses: It helps with stress, mood disorders, anxiety, fatigue, lack of appetite and pain. Improves focus and boosts motivation. 

Grow difficulty: Amnesia Haze comes with a moderate grow difficulty. It requires warmer temperatures to succeed. Since it doesn't tolerate cold so well, growing is preferred indoors. The results won't be great if you grow outside and there are big drops in temperature during the fall season. A fine harvest is of course possible by honing your grow skills and getting the environmental factors right for Amnesia Haze. 

Flowering time: Flowering stretches between 10 and 11 weeks for Amnesia Haze plants. Growers must ensure proper growing conditions consistently through this cycle.

Side Effects: Amnesia Haze has fewer adverse effects compared to other Sativa plants. It might cause the regular dry mouth and dry eye sensations, but staying hydrated can help address any such issues. A very small number of people might experience paranoid thoughts - if you are one of them, try not to overconsume or switch to a strain that better suits your body and brain.

How to Overcome Growing Challenges with Amnesia Haze?

Amnesia Haze has an extended flowering time. Indoors it can flower between 10 and 13 weeks, while outdoors around 10-11 weeks. Outdoor harvest typically occurs in November, but if you live in areas where cold temperatures persist during the fall months, avoid taking your pots outside. 

Determine whether to grow plants outside or inside based on the local climate where you live. Amnesia Haze requires warm temperatures consistently throughout the entire growing cycle. The optimal temperature range is between 70-85°F (21-29°C).

Besides flowering and climate, another thing you should pay attention to when growing Amnesia Haze plants is having enough space. Plants grow tall and stretchy, so one way to deal with that is taking clones straight into flowers, or work hard on training your plants.  

Even if you have sufficient space for cultivating tall plants, growers are better off when they space out between each plant. Spacing out will enable lateral branches to breathe and access more light as they stretch out from the thick central stalk. The indoor space needs to be well-ventilated at all times. Consider trimming the plant's broad fan leaves so that air and light can reach the lower parts of the plant.

If you are growing outdoors, use large pots to accommodate your plants. You will also need to prune regularly to keep the shape and size of the plant tidy. If you want to get Amnesia Haze with an authentic smell and taste, use organic soil to grow your crops. Growing inside can also be done in a hydroponic setup. 

How to Feed Amnesia Haze Plants?

As with other factors, Amnesia Haze cannabis requires a bit more care with food and nutrients than other plants. You can use organic liquid fertilizer solutions to boost the immunity and resilience of your Amnesia Haze plants. Compost tea will work excellent with this strain (learn how to prepare compost tea here). 

Compost tea can be put in spray bottle and applied directly to the plant's foliage. This will help the plant's good bacteria combat harmful bacteria. Through its stomata, the plant will also absorb micronutrients that will support its growth processes. Solutions such as compost tea should as well keep the plants safe from pests and invaders. 

Is Amnesia Haze Cannabis Easy Pick for Beginners?

As much as enthusiastic you might be about growing Amnesia Haze in your own yard, wait to grow this strain until you are ready and have the necessary grower experience. While the problem is not the moderate difficulty for cultivating Amnesia Haze, it falls down to the diverse set of grow skills that growers should master to cultivate a strain like this. When you grow a bit simpler strains, you can hone those skills one by one.

Specific challenges will come when Amnesia Haze plants enter their flowering stage and when suddenly the amount of gardening work required doubles. Novice growers might also not be as much time-committed to grow this cultivar. Solely preparing compost tea, which should support the feeding regime for Amnesia Haze, will demand a good amount of time. Regular pruning to control the plant's size and shape also sucks time, as are regular checks if plants receive sufficient light and air.
