American Haze x California Haze exhibits the classic Haze plant characteristics. Its foliage is relatively sparse due to wide internodal gaps, giving it strong resistance against mold and mildew that usually hide in dense growth. Its leaves are narrow and slender, and the calyx-to-leaf ratio is high for easier trimming after the buds are collected. Those buds can get very big, adding weight that could cause the stems to bend and snap. As such, support structures like a trellis or bamboo stakes are highly recommended.
As a Sativa, it prefers warm weather and semi-humid conditions. If you are lucky enough to live in an area with a tropical or subtropical climate, you can grow this strain outdoors. It will appreciate the balmy breezes and strong sunlight that will encourage it to extend to its maximum height of about 180 to 200 cm (6 to 6.5 feet). Each plant will produce an impressive 500 to 600 grams (18 to 21 ounces) of aromatic, crystal-coated nugs from mid to late October.
However, if the climate is not ideal, indoor cultivation is the better option. A grow room with a high ceiling would be perfect; otherwise, leaf burn is a risk since the top of the plant might get too close to the grow lights. LED or fluorescent bulbs do not produce too much heat, but if you would rather use HPS/MH lamps for more vigorous growth, you should employ training techniques to limit the plant’s height.
The simplest strategy is a combination of Low-Stress Training (bending the branches) and the Screen of Green (ScroG) method. For advanced growers, topping and fimming are also suitable for promoting lateral growth instead of vertical expansion. Mimic equatorial conditions by keeping the temperature between 18 and 28 degrees Celsius (64 to 82 degrees Fahrenheit) for a yield of 400 grams (14 ounces) per square meter of grow space. Additionally, make sure to maintain the RH (relative humidity) at 40 to 50% during the 10 to 12-week flowering period.
