Water Requirements

Every indoor grow room should have a thermometer and a hygrometer installed because accurate measurements are essential for maintaining a healthy plant environment. Ideally you will use a thermometer that not only shows current temperature but records the high and low measurements for each day. This will give you valuable information as to how well your cooling and venting systems are working. The ideal temperature for an indoor grow is 72°F–76°F. The best range in relative humidity is from 60–70 percent for vegetative plants, dropping to 40–60 percent during the flowering phase.

The plants' water intake should be monitored daily, especially when they get bigger and use more water and have less room in their containers. If soil in the container is pulling away from the edge of the pot, it is time to water. The best time is when the soil is just starting to pull; otherwise, you will waste a lot of water that runs down between the pot and the root ball, and the plant might not be getting much at all.

Cannabis plants that are stressed for water will signal to you by leaf droop and a wilty look. They can bounce back very quickly, but stressing the plant over and over will take its toll. Do not let the plants dry out and beg for water, but ideally water deeply once a week.
