The vegetative stage of cannabis is the primary phase of the plant’s growth cycle when it’s actually growing versus yielding bud. In nature, plants receive over 12 hours of sunlight in the summer and will remain in a vegetative state. As the seasons change, there is less light, so the plant will begin to flower. If one is growing inside, there is more control over the light cycles, therefore the plant can move from the vegetative to the flowering stage whenever the grower wants.
“To get the most bud from your plants, allow them to stay in a vegetative state until they’re about 3-4 nodes tall and with stems that are 5-6mm thick.”
