Quality soil should be dark, rich in nutrients, and have a light and fluffy texture. The structure of your soil should be capable of retaining water but also allow for drainage of any excess. Organic potting soil blends from your local garden center will do just fine, but more advanced growers prefer to blend their own organic super soil from scratch. The soil itself should be slightly acidic with a pH of around 6. This can be tested with a soil pH meter or test kit.
Daytime temperatures between 75 and 85 degrees Fahrenheit (23.9 to 25.4 degrees Celsius) are ideal for cannabis, while temperatures above 88 degrees Fahrenheit (31.1 degrees Celsius) or below 60 degrees Fahrenheit (15.6 degrees Celsius) can delay growth. Cannabis is considered heat-tolerant, but sustained highs and extreme lows will usually lead to complications that could eventually kill your plants.
The amount of water a plant needs largely depends on its size, the size of its container, the soil type, and general environmental conditions such as the weather and the intensity of the sun. Larger plants in warmer environments tend to use more water than smaller plants in cooler weather. The amount of water needed will change throughout a plant’s life cycle.
Keep this info in mind as you embark on your cannabis-growing adventure. The smallest adjustments can make all the difference — planting a week earlier, a week later, watering less, watering more, etc.
During the vegetative phase, plants need more nitrogen in order to create the roots and leaves that serve as the base for flowering. During the start of the flowering cycle, the plants will require more phosphorus and potassium than nitrogen. Towards the end of the flowering cycle, once the majority of the nitrogen has been depleted, the plants will focus their attention on using the remaining nutrients. The lack of nitrogen is largely responsible for the vibrant purple and orange hues that can be seen on large fan leaves and throughout the plants’ colas.

Experienced growers also recommend keeping an eye out for a change in color in the plant’s stigma. A good sign that the plant is ready for harvesting is when the stigma changes in color from white to orange. However, most growers agree that the most accurate method to determine when it is time to harvest is to wait until the trichomes have turned opaque white.

While insects damage your plants over a few days or weeks, larger animals can destroy them in minutes. You must examine your cannabis plants daily.
