In the field of horticulture, vegetative stage refers to the stage of plant growth that happens following germination and just before flowering. During the vegetative stage, a plant will produce most of its foliage and it is known as the stage that a plant will flourish the most. Throughout the vegetative stage, plants are going through the process of photosynthesis. They are focused on collecting nutrients, CO2, and lighting, all of which are required for flowering and the reproductive process.
During the vegetative stage, plants are typically known to be more fragile in comparison to the flowering stage. The plant will gain a considerable amount of height in the vegetative stage. While they are a leech to all essential nutrients that are required for plant growth in this stage, nitrogen is the pinnacle of them. Once the vegetative stage has finished, the plant will gravitate towards requiring more potassium and phosphorus in order to start blooming flowers.
The majority of plants that grow outdoors will go through the vegetative stage in around late spring and summer. The length of time it takes for each plant to reach maturity is different from one to the next. For indoor plants, it is necessary to provide them with at least 18 hours of lighting to encourage them to blossom. Blue spectrum grow lights are highly recommended for indoor plants that are currently in the vegetative period of growth. The veg stage and the growth stage are two terms that are also synonymous with the vegetative stage.
The flowering stage which follows after the vegetative stage is known as the bloom stage, and plants in each cycle of development will require different lighting and nutrients in order to grow. Growers will sometimes separate plants into different rooms depending on what cycle of growth the plant is in.
