The Cycle of Life of a Marijuana plant: An epic story
As any yearly plant, Cannabis’s life cycle ranges from germination to flowering, after which the plant dies.
We can divide this life cycle in 7 stages, starting at germination and ending at the harvest of it’s sweat sweat flowers.
What are the stages of Marijuana’s life cycle?
- Choosing your seed
- Germination stage
- Sprouting or seeding stage
- Growth stages
- Flowering period
- Harvesting time
- Drying and curing the flowers
Let’s go over these different steps in detail:
Choosing your seed
The choice of your seed is crucial. The different families of Cannabis available have characteristics unique to each.
These changes range from environnement you must provide them to the effects they will produce.
The 2 main categories are Sativa and Indica plants.
You can also find a range of seeds that are hybrid, containing traits from Sativa and Indica families. Let’s go over these differences :
What are the differences between Sativa and Indica plants :
| Indica | Sativa | |
| Flowering period | 45 to 90 days | 70 to 120 days |
| Tempature and Humidity | Weaker resistance to heat | Stronger resistance to heat |
| Effects | Chill high Good after a long day working or chilling at home |
Hyper/Laughing high Good for going out or having a bunch of friends over |
| The Stretch | About 2 weeks long, plants with an Indica dominance will grow between 80% and 150% during the stretch. |
Same time period as its cousins, Sativa plan wills grow from 100% to 250% of its size during the stretch. Do not underestimate this! Orelse you might just have your flowers touching your light |
| Growth during the Flowering stage |
Indica plants stop growing in hight once the stretch period is over. |
Sativa plants will keep on growing after the stretch, although this growth is much slower. |
| What will the buds look like |
Generally Indica weeds have more compact buds. This is due to the fact that they originate from colder parts of the world. |
Since Sativa plants originate from warmer area’s of the world its buds will be fluffy and aired out. |
Now I’m guessing you might want to store some seeds?
It’s actually very easy, there are just couple rules to follow
How to store your Marijuana seeds :
- Keep your seeds in a dark space
- Keep you seeds in a dry environment. Humidity will wake them up
- Keep your seeds at room temperature
And voilà! You can keep your seeds until you’re ready to get them started!
Germination of the marijuana seeds
Once you have chosen and received your seeds it’s time to get started with these babies.
There are different ways to get your seed to germinate, but here I will talk about the simplest way to do so.
What is the easy easiest way to germinate a Marijuana seed?
- Get 2 plates or saucers and 2 sheets tissue.
- Get the tissues moist.
It is important to get this part right, if the tissue is too wet, the root won’t need to exit the seed.
To dry though and the baby root won’t have enough to survive - Place the seeds between the 2 sheets of tissue and on a plate.
- Place the 2nd plate over the first in order to keep the seeds in the dark and store them between 20°C and 25°C
- During the next couple days, keep an eye on the humidity of the paper.
You will need to drop a couple drops of water regularly. - Once you have a nice little root, carefully remove the seed.
- Place the seed between 5 and 10mm in your soil.
It is important for the root to be facing downwards.
The Sprouting or seeding stage
A couple days after placing your seeds in the soil, you should start seeing a little sprout come out.
Say hello to your Baby Mary plant, congratulations!
Now just like a infant, the path ahead is full of (fun) obstacles, get ready to rumble!!
Here are a couple images of one of my own little ones :
Day 0 : The baby plants just breaking the soil and standing upright
Day 3 – 10 : Standing up, going for the light and growing first main leaves
With this run I learned that it’s really important to keep the light nice and close (~50cm) the first days.
As you can see they got so long that once they started growing the main leaves they got top heavy…
If that ever happens to you, just get a piece of wood or pencil to support them, in time they’ll get strong enough to stand on their own
The Growth of Cannabis
The vegetative stage is divided into 2 time periods, vegetative stage and the stretch.
Let’s go over these 2 fascinating times of her life:
The Vegetative stage
Once you plant has created her first main leaves, she will continue to do so, creating leaf and branch in sequence.
If you environnement is nicely tuned up these nots should be appearing nice and close to one another, which is perfect! Your future buds will be nice end dense.
Generally, apart from auto-flowering seeds, you have the control on how long it lasts. As long as you keep the light cycle in 18hours of light and 6hours of night, they will stay in this stage
What are the characteristics of Marijuana’s Vegetative stage:
| What you will see | |
| Growth | Steady growth during the period. Make sur to cut the branches that won’t get enough light as the plant grows. Better to have a few strong branches than a bunch of week ones |
| Branch and leaf density | In sequence she will produce 2 new leaves, 2 new branches |
| Humidity | Going down over time, it should start at around 65/70% humidity, ending around 50% |
| Temperature | Really during her whole life you should aim around 25° I know, I know, not easy…. |
| Nutrients | During this stage you will need to give her mainly Nitrogen. She use and store it in her leafs in for photosynthesis as well as back up energy when she creates her bud creation later on.I would also keep giving her root nutrients all the way up until the stretch. |
| Light cycle | Keep about 18hours of light and 6 hours of night |
| Length in time | As long as you want. As long as you don’t switch the length of light exposure they will stay in this mode |
During this stage you must make sure to give the plant enough Nitrogen nutrients.
In order to get the right measure you really have to test and learn with the strain you have, although I have found that going a little under the dosage given in the bottle works out pretty well.
Quick Warning : After the stretch the plant reduces its intake of nitrogen, making it real difficult to fight nitrogen deficiencies during the flowering stage.
I’m not saying go all out on Nitrogen! Get hit with nutrient burn or Nitrogen toxicity and you’ve got a whole other set of issues on your hand!
The Stretch and Pre-flowering
You’re now ready to get you plants to the flowering phase of her life? Are you sure? Just like a teenager she’s going to throw some fits, and you won’t recognise what come out of it!
Alright if you say so, let’s go through the different aspects of the Stretch and Pre-flowering stages of your Marijuana, but first, couple pics of our own!
Let’s get into what it’s all about
What are the characteristics of Marijuana’s Stretch stage:
| What you will see | |
| How to start it | Change you light pattern from 18/6 cycle to 12/12 cycles. |
| Growth | Very rapid! Depending on Sativa or Indica strains it can vary from 70% to… over 200%! Sativa’s grow the most during this time, so get a meter out and start measuring to max hight in your space |
| Length in time | 2 weeks long |
| Humidity | 40% to 50% |
| Temperature | Around ~ 25°C. Be sure to measure at the level of your Apex’s! |
| Nutrients | Reduce the levels of Nitrogen given over time Increase the levels of Potassium and Phosphorus. |
| Light cycle | 12hours of light and 12 hours of night |
| Branch and leaf density | The Apex and branches will take in high very rapidly, keep an eye out in 2 weeks time you won’t recognise her anymore! The leaf mass at this point won’t vary, and that’s a good thing, you want her focusing on the buds by the end of this |
By the end of this phase she will start having some small flowers on her, congratulation’s you’ve entered the flowering phase! You’re once baby sprout has become a young adult.
Here’s a picture of what my Bleu Thaï looked like by that time
You can start noticing the with hair like strands growing at the intersection of your branches and the top of the Apex, I present to you the early Flowering stage!
The Flowering stage
Welcome to the finale stage of life of you Cannabis strain, you’d think you’re almost done huh? but not really..
what you’ve done up to here are the foundations for what’s to come 🙂 now let’s get building up
As always, before we get started here’s a couple pics of one of own at this stage
Harvesting your Marijuana plant
I find that choosing when to harvest your Cannabis is one of the toughest decisions, you can alway wait a little… but once the CBD starts rising it’s going to be one of those couch potato weeds… So kinda tricky.
I’m still working on this part, come back in a couple days 😉
