After the seed has been planted and the soil watered well, you don't need to water again for a few days.
The amount of water, and how often to water varies with the size of the pots and plants, and the amount of light.
When plants are small they transpire less, and don't require as frequent watering as when they are larger with more leaves.
When seedlings have just appeared above the ground, you should water very carefully to prevent the force of the water knocking them over.
Water provides the hydrogen necessary for plant growth and also carries the nutrients throughout the plant.
Cannabis plants prefer a regular watering cycle, but should preferably not be watered every day.
Although the theory that the more water a plant is given, the faster it will grow is incorrect, underwatering will slow plant growth.
Although the Cannabis plant loves lots of water, the most common cause of death in homegrown plants is from overwatering them.
A large pot that was saturated before germination may hold enough moisture for the first two to three weeks of growth.
Plant cells are kept rigid by water, and when there is not enough moisture left in the soil, the leaves start wilting and dropping off.
