Vegetative Stage

The Vegetative Stage begins when seedlings start their rapid growth above ground. What happens prior to that is a explosive growth in the root systems of the seedlings. This rapid growth in the roots allows the plants to uptake more nutrients. This leads way to the rapid growth above ground.


Lighting is a big factor in the vegetative stage. It single-handedly decides the difference between Vegetative stage and Flowering Stage. You need to make sure your plants get enough light and even the distance between your plants and the light need to be accounted for.

The perfect amount of light in the vegetative stage is 20/4 light period. This means that you need to keep the light on for 20 hours then off for 4 hours. This gives the best ratio of light to dark and allows for maximum growth in your plants.


It is important to note that even though the vegetative stage has started you still need to be careful not to over do the nutrients at this point. I would increase the grow nutrients of your feeding schedule until you start to see a little burn on the tips. This is of course only until you know the strain your working with and how it will react. Once you know what your strain can handle in vegetative stage then you don't need to do this testing.

The big nutrient players in the vegetative stage are:

  • Nitrogen(Biggest Player)
  • Potassium
  • Phosphorus
  • Calcium
  • Magnesium
  • Sulfur
  • Trace Elements

These nutrients get used up at a much faster rate in vegetative stage then they did in the seedling stage. Which is why you want to make sure that you keep a eye on them and make sure they are getting feed well and not drying out.

The PH of your feeding schedule also plays a very big roll. PH will determine how well your plants will uptake the nutrients. If PH is to high(above 6.2) or to low(below 5.2) the roots will not take in nutrients this is called Nutrient Lockout. A PH of 5.8 will ensure the best results and take the guess work out of troubleshooting PH issues with your plants.

A good way to keep the feeding and PH in check is to use a High Quality Plant Nutrient like "Bare Naked Nutes -- Grow Nutrients". Bare Naked Nutes nutrients are all PH balanced and need no additives and they wont break the bank.


In the Vegetative Stage a number of other things also take place like:

These all take place in the vegetative stage and play a big roll on how your marijuana will look and how it will grow up.
