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).

This picture was taken just before I turned these White Rhino plants over to flowering. I like to keep my grows short and quick when growing with CFLs.
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?

The size your plant gets in this stage will have a huge impact on the final size of your plant.
