After security the most important thing for your cannabis plants is ligh, included those from feminized seeds. Light is the most important thing because the amount of light determinate how large your plants will be. To find the right light source you have to take a good look around for the best window or electric lights. The expression “light cycle” means how many hours the cannabis plants should be in the light and in the dark. The amount of time that the plants are in the light will determinate how fast the plants will grow and if they will produce vegetative or floral growth. The term “intensity” says something about the strength of the light. The intensity of the electric lights varies with the wattage of the lights and how far the lights are from the cannabis plants. The wavelengths and the color of the lights are also very important for your plants. The two most important colors are blue and red. They never use green because it reflects. If you give your cannabis plants 24 hours light a day it will grow quickly and produce non floral growth.
