Vegetative Cannabis

What is Vegetative??

The vegetative state, is when a plant has survived sprouting and has developed a root ball. It can now focus on producing leaves and stems and getting closer to the sun.

Before transplanting your seedlings and preparing for the vegetative state, make sure the plant has a good strong stem and root ball.

This will help, if the plant goes into shock.  Plant will go into shock when they are traumatized.  Keep the roots moist and the plant directly under light to help the plant stabilize.

Some roots will break when transplanting, but as long as the main root system is intact the plant should survive.


First, choose pots that are suitable to your grow space.

Cannabis plants can grow tall so if your growing indoors there’s a little more maintenance that needs to be done to keep their size smaller.

For the outdoor growers the sun and soil will do most of the work 🙂

For my indoor plants I stay at 12-16” pot, to ensure they get plenty of space for strong roots.  These plants are likely to be over 5ft.

I’ve seen outdoor plants grow over 7ft.

You want to make sure the pots have drainage holes at the bottom. (I usually cover them with some netting so my soil doesn’t drain out when watering.)

I’ve seen pictures of miniature cannabis plants. I don’t know about their yield, but I plan on attempting my own experiment, so I’ll let you know how it goes.

Choosing Soil    

Use organic soil, it always produces the bestyield.   I didn’t use any secret soil mix

T    here are companies who claim to have specialty soil for cannabis), I just picked up some EB-stone organic soil from OSH, with a bag of the charcoal and peat moss (all organic EB-stone products). little vege

I mix the charcoal and the peat moss and put half in the bottom, then use the organic soil in the middle and sprinkle the remaining mixture on top.

(I don’t know if it makes a difference how you mix the soil that’s just how my mom used to plant her garden.)

The thickest layer should be the organic soil, which is where you want the roots to be placed during transplant.

(Sometimes along with the charcoal and peat moss I’ll mix in some pebbles to get better drainage.)    Very important to avoid mold and mildew.


Feeding the Plants

I’m not a hydroponics expert, (I do grow my plants with soil), but we still need to add nutrients about two weeks after transplanting.

The plants will “drink up” the nutrients to complete its recovery from the transplant and start new growth. Growth will begin to slow if they don’t continue to get the correct nutrients.

I’m going to try a variety of different nutrients, but vegetable nutrients will do the job. burned leafs Anyway, wait 1 ½ to 2 weeks after transplanting before you start feeding.

Don’t over feed the plants.  You can hurt the plant and even kill it by over feeding.

The leaves will tell you when its getting too much or too little nutrition.  Leaves will show signs of burn, spots, yellowing.  Its important to know these signs and adjust your feeding.

This can be critical during the flowering phase, so keep track of your feeding throughout the plant cycles, it’s important to keep a log of when you feed and water the plants. I add organic nutrients to the water once every other week or every ten days.


How much water to give the plants, will depend on how fast the soil drys.  Air circulation, type of pot, and number of plants, can all affect how often watering is needed.

I suggest getting something to keep track of the moisture and PH reading.  It allows for better control when watering and feeding.

I water every other day to every three days, depending on soil moisture.

Humidity needs to stay between 55 -75 degrees and the temperature should stay around 60-80 degrees.

(Adjusting temperature will also depend on the seed type, some do better in colder weather).

Personal Note: I did notice about the forth week, that my plants had kinda stunted.  I wasn’t seeing the same accelerated growth I was used to seeing.

This isn’t always a bad thing, the plants will go through normal fluctuation periods, but in my case it seemed just a little strange.  I realized that the soil was pretty impacted and probably wasn’t getting enough oxygen.

My solution, EARTHWORMS, after putting a few earthworms in each pot I saw an immediate difference.  Earthworms are great for making sure your soil is nutrient rich and oxygenated.8857597748


The plants should be kept in “full sun” throughout the vegetative state.

If you plan on cloning you’ll want to keep it in the vegetative state for a while.  This means little to nosmall plant darkness.

I go with a 0-24 darkness to light ratio. Since my plants are indoors this means florescent lights 24hrs daily.

If you don’t plan on leaving the lights on, you’ll want no more than 6 hrs of darkness during the vegetative state.

I probably wouldn’t give it the full 6 hrs of darkness, just to make sure the plant doesn’t hit the flowering stage prematurely.

For indoor plants, adjust the light so it stays 6 – 12 inches away from the highest branch, you don’t want to start burning leaves.

But keeping the light close to the plants allows them to develop stronger base branches.  Important if trying to get a large yield from a single plant.

Growing outdoor, the plants will have a natural vegetative and blooming period, it will depend on the natural changes of daylight in your geographic area.

With indoor plants, it is possible to initiate the flowering phase after 4-6 weeks of vegetation.

This is a little premature, which is fine when keeping your plants small.

Although I’m growing indoors, I do plan on vegetating for the full 6 weeks, maybe a little longer.

Pruning is important, throughout the vegetative phase because the plants will continue to grow during the flowering phase and could possibly double in size.

Pruning is also a way to control the growth pattern of the plant.  I have seen pictures of people doing some incredible things to plants through pruning.
