As it grows, Amnesia #7 looks like a typical Sativa. It has a lanky frame with sparse foliage of slender, light-green fan leaves. That said, its main stem does not stretch as much as its cousins during the vegetative stage. The result is a shorter plant with a more bush-like shape. The branches are also more woody than fibrous, giving them robustness that makes it easier to carry the weight of the large, lime-green buds. Additional support like trellises and stakes are usually unnecessary.
Because this strain only grows to a medium height, it is excellent for indoor cultivation. Just make sure to maintain a safe distance between the grow lamp and the top of the plant to prevent light burn. But take care, too, not to place the lights too far away to avoid a growth spurt that could impede the “fattening” of the shrub. This type of overstretching can decrease productivity.
If moving the grow lights is not an option, it would be better to use training techniques to limit the plant’s size. You can combine Low-Stress Training (bending the branches) and the Screen of Green (ScroG) method to stimulate horizontal expansion instead of vertical growth. Experienced growers can also try topping or fimming.
For best results, the grow room should be relatively warm. Keep the temperature within the 21 to 29-degree Celsius (70 to 85 degrees Fahrenheit) range. Monitor the relative humidity as well, aiming for about 40 to 50% during the flowering stage. After 9 or 10 weeks of budding, you can drop the RH to 30 to 40% for the last 2 weeks before harvesting. If all goes well, you should be able to collect 500 to 550 grams (17 to 19 ounces) of elongated, yellow-haired nugs per square meter.
If you live in a sunny, balmy area similar to the tropics, you can also raise Amnesia #7 outdoors. Give the plant enough water and nutrients, and it can grow to about 180 cm (6 feet) and produce 600 to 700 grams (21 to 25 ounces) of usable bud. Prepare to harvest in late October.
