Growing 4 weed plants per household will be the limit for most Canadians

Canada is one of the first “first world countries” to allow growing cannabis at home for all its citizens. However, citizens living in Manitoba and Quebec will not have this privilege as their provinces have decided to opt-out of that.

Eight out of ten Canadian provinces decided to allow growing up to four cannabis plants per household for recreational consumption.

Some provinces have further legislative pieces working around where and how to grow those plants, as some provinces don’t like to have them visible from the street, but in essence all 8 provinces allow for growing 4 plants.

So, what can you do with 4 plants? How much weed are we talking? Indica or Sativa? Are we growing in water or growing in soil? All these questions unanswered…

Well, with a little bit of proper growing knowledge, some money invested in decent lighting and a little bit of time and effort, you won’t have to spend a dime on buying recreational cannabis from the stores.

Really, 4 plants can be more than enough for 2 people living on their own.

Think about it: how much weed can two normal adults smoke in a day? 3-5 grams at the most, and that’s if they try really hard, or at least that’s my educated guess.

So, let’s take 4 grams as an average for two people who are daily cannabis consumers and do a little bit of math.

Increase yield through proper lighting

Giving your plants enough light for them to grow monstrous meaty buds is essential and every grower knows it. But, just how much light do you actually need?

Here is a list of how using lighting can affect your yield. But first, let me explain it shortly.

The low yield numbers are what is expected for someone who is not experienced in growing and is not using any of the advanced techniques (we’ll get to this a bit later) for his current grow.

Average numbers are what growers may get if they are somewhat experienced in growing and can recognize certain patterns and issues when it comes to growing.

The high yield numbers are somewhat far-reaching as those are the numbers people working in production facilities expect.

These high yield numbers cannot be achieved without mastering the growing process and applying several advanced techniques and thorough knowledge of the growing process.

1000-watt HPS250gr500gr1000gr1.5 x 1.5 x 2.5 m.

As for the seeds, strains that are known to bring in high yields would always be recommended. In my opinion, I would suggest easy to grow strains with high yields such as Super Skunk, Sour Diesel, and Northern Lights, but you can also opt for something else you prefer as long as you are familiar with the strain and how it behaves during the grow.

So, with this chart the math is clear. If you decide to invest in some powerful lighting, you can end up with at least 1kg of cannabis every 3 months.

This means that every 3 months you’ll have a batch of a 1000 grams to smoke before your next batch comes in.

Three months are 90-100 days of growing, which means that even if this theoretical growing couple smokes 10 grams per day, they would only smoke 900 grams before the next harvest.

On a good harvest, however, you may even get up to 2 or 3 kilograms with some help from the advanced growing techniques we’re about to explain.

Increase yield by manipulating plant structure

Making your plant grow one way or another can make a significant difference when the time is right to harvest the plants.

Having the best lighting equipment can mean very little when the light cannot reach the biggest leaves and give the plant the energy it needs.

So, moving your plant around and steering the way it should grow is also one of the best ways to increase its potential yield.

There are several ways to do so, and we call them advanced growing techniques here at Greencamp. Most of these techniques rely on exposing the bottom leaves and the ones hiding to the light.

Basically, most of these techniques rely on you setting up some kind of backbone or a system of support strains that are supposed to hold the branches and leaves upwards toward the light.

Three of the most well-known systems are manifolding or main-lining, Screen of Green, and Super-Cropping.

Main-lining or manifolding

Manifolding is the process of splitting your plant down the middle branch while it is still in its earliest stage.

By doing so you will create a plant where the main stem was split evenly into two parts, both of which will behave as the main branch and you will get that “pitchfork” look.

These two branches will start growing bigger and bigger and eventually they will branch out a little bit themselves as well.

Once the two branches have branched out and they start flowering they create very long thick colas with very meaty nugs on them.

Manifolding will usually provide you with 2-4 massive colas which can bring in up to 200-300 grams on their own, and you’ll still have all the smaller branches to harvest.

Screen of Green

This technique is getting more and more popular, especially with those looking to make huge yields and sell their product, such as licensed producers in Canada.

The Screen of Green technique uses a net or a wire mesh to control the height of the plants.

The whole point of the net is so that all the leaves and branches can hold onto it, in order for the plant to become bushier. A bushier plant means more places for nugs to grow, which means a bigger yield for you.

So, in order to grow massive crops, forget about the classic pyramid-shaped cannabis plant look and opt-into a more bushier look with more room for nugs to grow.


Super-Cropping is not something you should do if you don’t know with full certainty what you are doing with your plants. Why?

Well, because Super-Cropping is basically hurting your plants so that they produce bigger yields. If it is not being done properly it can lead to your plants dying off.

So, all you need for doing this is your hands and the cannabis plant. Basically, you’ll want to take a couple branches which aren’t the main stem and kinda bend them in half without breaking them.

You should do this with multiple branches on the same location on the branch. It sounds more complicated than it is, but basically, all you have to do is squeeze the branch with your fingers so it gets bruised.

This will signal the plant that it is hurting and it will start sending more of the stuff that makes the plant grow into the branches that are hurting. This stuff will also impact your nugs and they will get bigger.

If I explained this technique poorly it’s because I’m totally overcomplicating it. Here, just take a look at this video and it will make perfect sense:

Temperature and humidity

Controlling the temperature and humidity within your growing area will also be a significant factor in your grow.

You simply mustn’t allow your grow room to go cold or else your plants might freeze overnight.

The ideal temperature for growing cannabis is around 25 degrees Celsius, so you might wanna keep it around that level.

Also, if you want to really get into it, try controlling the humidity of the grow room, as the air shouldn’t be too dry, but not too moist either as that can lead to developing mold.
