Raising your own Harlequin at home is not very difficult and can be done by neophytes in cannabis cultivation. It has a high resistance to pathogens and pests, but you should still prune it to get rid of non-essential leaves and branches. This practice ensures better airflow and allows the light to reach all the important parts of the plant – specifically, the bud sites.
Indoors, you can use the Screen of Green (SCROG) method to control the height and, at the same time, maximize the yield. In addition, make sure that the temperature stays between 21 and 27 degrees Celsius (70 and 80 degrees Fahrenheit) for optimum results. Keep the relative humidity (RH) level at 40 to 50% during the flowering stage, and bring it down to 30% to 40% two weeks before you harvest the buds. The flowering stage will take 8 to 9 weeks, and you can expect around 700 grams (25 ounces) of aromatic buds per square meter.
Outdoors, Harlequin enjoys a stable Mediterranean-like climate. It thrives best in Australia, California, Italy, and the coastal area of North Africa. Even though it loves basking in the sun, it could wither and dry if it gets too warm; therefore, you have to give it some shade during the hottest part of the day. You can also water it with compost tea to keep it healthy so that it can grow as tall as 150 cm (5 feet). Collecting the buds can begin in mid-October, with each plant supplying you with 600 grams (21 ounces) of usable weed.
Should you choose to use regular seeds for cultivating this cannabis, bear in mind that they have an equal chance of producing both male and female plants. If you want to reach the target yield, we recommend that you germinate twice as many seeds as you would for feminized plants. Don’t forget to keep the males and females separate in order to avoid accidental pollination.
