How to Take Care of Indoor Kush Plants


Kush is a high-potency form of "Indica cannabis" or marijuana. It originally came from Afghanistan and derives it name from the Hindu Kush valleys of eastern and central Afghanistan and northwestern Pakistan. Kush is the type of marijuana best suited for growing indoors and the type most often grown for medicinal purposes. (Before potting up some pot, however, read the Warnings section at the end of this article.) Wherever it is legal to grow kush indoors, there are a few basic things to know in order to take care of your indoor kush plants.

How to Take Care of Indoor Kush Plants

Step 1

Indoor kush plants tend to produce shorter plants than other strains of marijuana--growing to be only about 4 to 5 feet tall. Nevertheless, it is recommended that each plant be grown in its own individual pot.

Step 2

Soil conditions. The soil should have good drainage. Use loamy soil or good compost. Maintain a pH level between 6.5 and 7.

Step 3

Fertilizing. Fertilize sparingly to avoid burning up the plants. Use a balanced fertilizer, for example, N-K-P/12-12-12. This means that the fertilizer contains 12 percent nitrogen (N), 12 percent phosphorus (P), and 12 percent potassium (K). Err on the side of a bit more nitrogen when the plants are going through their growing stage before budding.

Step 4

Water. Water about every two to three days. Do not overwater. However, you do not want them to completely dry out between watering. If you see signs of dehydration or notice the leaves drooping, water more often.

Step 5

Air. Plants emit oxygen and require carbon dioxide. Kush is no exception. Give your kush the necessary carbon dioxide by using bottled carbon dioxide, a carbon dioxide generator, a mixture of baking soda and vinegar or dry ice. In addition, kush needs good air circulation. Use one or more oscillating fans.

Step 6

Room temperature. Usually kush is grown in its own separate grow room. The temperature in the grow room should be kept between 75 and 81 degrees Fahrenheit during the day and not allowed to drop below about 60 degrees Fahrenheit at night.

Step 7

Light. Kush likes light. If using incandescent bulbs, place the light just 2 feet above the plant. If using other types of light, such as fluorescent lights, place the light 3 to 4 feet above the plant. A good way to increase the light in your grow room is to hang reflective material on the walls or paint the walls white.

Tips and Warnings

  • Growing and distributing kush can carry some stiff penalties in the United States. For example, "The High-Potency Marijuana Sentencing Enhancement Act of 2009 (H.R. 2848)" was introduced by Congressman Mark Kirk, R-IL, and features maximum fines of $1 million and a maximum prison sentence of 25 years.
