Step 7: Vegetative Stage – Grow Your Plant Big and Strong
Once your plant grows the first “regular” set of leaves, it’s pretty much officially in the vegetative stage. How long is the vegetative stage?
Cannabis plants keep getting bigger and bigger with long days (vegetative stage) and start making buds when they get long nights (flowering stage).
Young growing cannabis plants grow fastest when the temperature is a bit warmer than a comfortable room temperature, around 70-85°F (20-30°C). But as long as it doesn’t get freezing cold or burning hot, your plants should be able to grow in a wide range of temperatures.
How often do I water my cannabis plants?
In this stage, your plant will focus ONLY on getting big and strong. Buds and flowers are not part of the plant’s vocabulary yet.
If you’re feeding your plant with additional nutrients, start at half strength as it can be easy to burn your young cannabis plants. Bring to 3/4 strength one plant starts growing vigorously and if your plant displays signs of needing more nutrients even though the pH is in a good range.
Only feed nutrients at full strength if the plant is showing signs that it needs more nutrients (lower leaves are turning lime green, then yellow, then falling off – the first sign of a nitrogen deficiency, the most common type of deficiency – if the plant is not getting enough nutrients).
At this stage, you can’t tell if one of your cannabis plants is going to be a boy or a girl yet. Wait, why do I care if my plant is a boy or a girl?
- Give plants 18-24 hours/light a day in the vegetative stage when growing indoors. 18 hours of light a day is preferable, 24 is for the experimental type of grower.
- If growing outdoors, try to make sure you plant gets strong, direct light for most of the day, at least from 10am-4pm, and more if possible.
The size your plant gets in this stage will have a huge impact on the final size of your plant.
