The Growth of a Cannabis Plant

Last Updated: December 29, 2021By Jason Levin

The Growth Of a Cannabis Plant

Growing marijuana may sound like a major endeavor, but really it can be as easy as you want to make it. Still, it’s a good idea to know at least a little bit about what to expect before you begin. Having a basic idea of what a “normal” marijuana plant’s growing season will look like is an excellent way to get started. Keep reading for the basics of growing marijuana.



What happens during growth?

Light is where plants get their energy. Thanks to the chlorophyll in all plants, they perform a process called photosynthesis, which involves taking in the energy provided by light. They also use water and carbon dioxide to convert that light into energy.

With a Pot for Pot, your marijuana plant receives everything it needs for growth with light from the sun, water from the tap, CO2 from the air and a specially selected nutrient mix.

The leaves of your plants help process all the energy needed for growth. Having some big, green leaves allows your plant to take in and distribute even more of these necessary sugars, especially if those leaves are exposed to lots of direct sunlight. This is why your plant will grow faster and faster; the bigger the leaves, the more energy it can take in, and the more fuel it has to grow.

What do the plants need?

Now that you know why your plants need certain elements to grow, it’s easy to see how a Pot for Pot makes the process simple. The main things any marijuana grower worries about are water, light, CO2, and nutrients and we’ve made sure those aspects were covered.


It’s crucial that you don’t give your plants too little or too much water. Under watering can deprive your plants of the fuel they need to survive while overwatering can “drown” them and encourage mold to develop. It’s tough to give perfect advice about watering since it really varies in different growing environments.

A Pot for Pot features everything you need to properly water your plants, such as:

  • Watering schedule
  • Pot drain saucer
  • Aeration topsoil mix
  • Adorable watering can


Light is essential for all plants, but it is especially important for marijuana plants because they are photosensitive. This means that traditional strains will need a specific light schedule to reach their flowering stage. The light schedule needs to be uninterrupted and consistent, or else your plants will get confused.

A Pot for Pot has simplified this process as well, by using autoflowering strains. Now instead of worrying about complicated lighting schedules, you can focus on watching your plant grow.


The main thing you need to know about CO2 is that it helps your plant produce sugars, or energy. The other thing to know is that most plants do fine on their own as there is usually plenty of CO2 around naturally.


Your plants are going to be hungry for the right nutrients during different stages of growth. This can be a bit tricky since feeding nutrients to plants is not quite like feeding humans. It is easy to do too much or the wrong combinations and actually hurt your plant. 

Once again, a Pot for Pot removes this worry with a feeding schedule and specially formulated nutrients such as:

  • Premium Mycorrhizae to help roots absorb maximum nutrients
  • Premium Microbe Food Supplements
  • Beneficial Bacteria
  • Specially formulated Superb Soil

The Marijuana Growth Stages

There are three stages worth thinking about when it comes to marijuana plants: seedling, vegetative (or the “growth” stage), and flowering.


Your plant is at its most vulnerable during the seedling stage, but it doesn’t last long. It takes between 3-6 weeks for photosensitive plants (and is much shorter for autoflower strains). Follow your watering schedule carefully during this stage.  


Your plants are about to grow the most. You can practically see them getting bigger in front of your eyes! This will last between 1 and 2 months for a photoperiod schedule and much less time for an autoflowering strain, which only needs about 10 to 12 weeks total from start to finish. Pay attention to the schedule as it will likely change during this time and you may start adding nutrients.


This is when your plants start producing their delicious, THC-filled buds. It lasts anywhere between 6 and 10 weeks for photoperiod plants, and just a few weeks for autoflowering strains. This stage is often the most complicated for marijuana growers because ordinary marijuana plants grown indoors will need to be triggered into flowering; however, this is not the case with seeds used for a Pot for Pot. Your kit includes a discount coupon to purchase autoflowering seeds that will naturally enter the flowering stage without any help from you.  Pay attention to any changes in the feeding schedule though.

Prepare for harvest

When the flowering phase slows down, it’s time to prepare for the harvest. Check out your plant’s stigmas (the hair-like structures coming off the buds) first. These will turn from white to brown or orange. A plant ready to harvest has about 80% or so of her stigmas brown or orange. The most accurate measurement of readiness for harvest is actually the trichomes. These are the tiny, sticky structures that cover a plant's developed buds. They start clear and then change to cloudy to amber as they mature. A plant is ready to harvest when the trichomes are almost all cloudy. 

A Pot for Pot makes sure you are prepared for this stage as well – use the included scissors to harvest your buds, and find additional details about when and how to harvest printed on the back of your scissors packaging. And the MACRO camera lens that comes in the Complete Kits make it easy to see the trichomes! 

For the most successful harvest, it’s a good idea to do a little research before trying it the first time. Here's some solid resources:
