Vegetative Growth Stage

Vegetative Growth

The vegetative growth stage of cannabis growing takes place after the clone stage, or seedling stage (depending on how what you started with – clone or seed?), and before the Flowering Stage (when the plants start to grow marijuana buds). The vegetative growth stage for Cannabis plants usually takes place between week #2 & week #5, depending on how big your marijuana plants are and what strain you are growing, as every strain has it’s own specific life cycle.

The Vegetative Cannabis Growth Stage is the growing stage between seedling growth/cloning and the flowering stage. The seedling growth stage lasts about 2 weeks after the cannabis seeds have germinated. Once a strong root system is established and foliage growth increases rapidly, seedlings enter the vegetative growth stage. During this time it is crucial for you to know everything there is about your strain(s). As the plants mature, the roots take on specialized functions. The plant uses its center and old, mature portions to store food and transfer food and nutrients to the proper places. The tips of the roots produce elongating cells that continue to push farther and farther into the growing medium in search of more water and food. The single-celled root hairs are the parts of the root that actually absorb water and nutrients. If roots are exposed to light they will dry and be damaged.

How to Transplant Cannabis Clones into Vegetative Growth

Once you have established a healthy root system, its time to transplant clones to vegetative growth. This also applies to seedling growth. This seems like it would be very easy, but trust me, this process could make or break your harvest. You should always take extreme caution while transplanting, making sure not to damage any roots. First, make sure whatever medium you are using (rockwool or soil) has been soaked with water balanced at 6.0 ph for at least 1 hour. This will keep the roots from drying out. When using rockwool, make sure you do not crush or pinch any roots when transplanting. Once you have carefully inserted the plant into rockwool you now need to put this into a grow pot or bucket. The video below shows you step-by-step the proper way to transfer clones.

What Lights are Best for Vegetative Growth?

Vegetative Stage Light Cycle used to Grow Cannabis

Choosing the proper lights and hours to imitate the sun’s spectrum is crucial for vegetative growth. Using a metal halide light will give the plants the spectrum they need to grow healthy. Vegetative growth is maintained under 18 or more hours of light per day. I personally choose 24 hours of light to promote faster growth, as I need hundreds of plants weekly to maintain my warehouse grow operation. The best way to promote healthy, vigorous growth is to use a 250w halide to grow for the 1st week, 400w halide for the 2nd week and a 1000w halide for the remainder of time you choose to keep the plants growing prior to flowering. This method helps promote even growth without shocking the plant. I personally prefer Hortilux Eye Blue Metal Halide lights for Vegetative Growth as they have always worked the best. See pics below showing you the 3 different metal halides for vegetative growth.
