How to Grow Marijuana on a Balcony

gowing marijuana on balcony

I have been growing Marijuana on my 6th floor balcony in Australia 3 years in a row.

It worked great.

How much direct sun reaches your balcony? You need direct Sunlight that reaches your plant for at very least 3 hours a day.

Regarding on the intensity of sunlight in your place, this can be more. For example, here in Australia, the sun is very intense during summer. 3 hours direct sunlight and the rest indirect will already yield a harvest. But in Germany, 3 hours would probably not be enough.

This is my one of my balcony plants:

Growing Marijuana on a Balcony

This is the story of how I did it.

Start in Spring

The natural lifecycle of Cannabis makes if grow in Spring / early summer and then develop buds in late Summer.

So start your project in Spring.

I germinated 2 plants in October (October is Spring here in Western Australia). More on germinating Marijuana Seeds.

The plants were put into direct sunlight as much as possible.

After a while, they looked like this:

At this point, i started to add fertilizer to the water. I used common tomato fertilizer. It is probably not the best choice, but i did not have hydroponic fertilizer on hand.

Whichever fertilizer is chosen, it is wise to make sure it is suited for food plants.

The plants kept going. With ca. 4 hours of direct afternoon sun.

Automatic Watering

The large plants needed water twice a day.

This is easily forgotten and the green ladies suffer from drought.

So i built a watering system.

TimerThe pump pumps twice daily for ca 5 minutes water into the pot. Excessive water runs back into the reservoir underneath.

The pump is a little garden pond pump, connected to a timer.

The water contains fertilizer.

This way, you do not have to worry about watering the plants.

These plants were started in spring. Outdoor Marijuana usually starts flowering in the middle of summer, when the days are getting shorter.

Both plants turned out to be females. They started developing buds:

After ca 3.5 month:

It is harvest time. More than 50% of the pistils (little white hairs on the buds) have turned brown.

The later Marijuana is harvested, the more numbing is its effect. I prefer my weed not too numbing, but rather uplifting.

So I usually harvest when more than 50% of the trichomes are still white. The weed in the following picture is, in my opinion, overdue for harvesting.

The plants were harvested at the age of 4 month.

The buds were cut off and the small leaves in between were removed.

The harvest and curing is over, the fresh weed is left:

Now comes ….. drying.

The weed should dry slowly and in the dark.

If you are interested, please read the article on drying of Marijuana.

After the Marijuana was dried, i put it into plastic containers.

It came to 2.5 ounces of dried Marijuana.

I was happy with the result. Growing Marijuana on balcony is possible. It was a nice smoke. The strain was not very strong, but that’s alright because i harvested a large amount.

    Hi mate

    Love you post Jack and appreciate all the information you have.

    I am planning to start a sativa plant and just bought some seeds. I wanted to grow the plan in my garden outdoor with ground soil which is pretty good for plants. My only concern was i know the plant stinks a lot during flowering and if yes how far away can someone actually smell the scent? 3 meters? 5 meters? My garden is about 20m x 10m area and planning to only start with 1 plant.

    Also, will now be a good time to start planting one over at QLD with high temperature of 33-35c?

    Cheers

    Hi Jack,

    Hope your doing well, & thanks in advance for your continued support to the community.

    This is my first time ever trying to grow seeds. I live in Mumbai (India) & we’re almost nearing winter. Our weather ATM is between 25-35 degrees with about 12 hours of Sunlight & about 45-60% humidity. Are these conditions ok for an outdoor/balcony grow?

    I have literally started the germinating process just yesterday, & plan to shift the seeds into 3 different pots tomorrow. Would be great if I could get your input/opinion & advice on how to move forward.

    Couple of questions I guess (again thank you so much for taking the time & much appreciated)
    1) Are these weather conditions ok for an outdoor grow, or should i consider an indoor box?
    2) How long do I need to keep them in direct sunlight once they move from germination to a Pot?
    3) How much water do they need at this stage? & Does that change going forward?
    4) Do I need to move from a small pot to a big pot? Does it matter?

    Thanks a ton jack!!

      Hi,

      yes, the conditions are ok.

      Though it would be better if you’d start the grow at the beginning of summer. So you follow the natural cycle of the plant.
      But 12hrs of sun is still a lot and the temperature is war. So definitely go for it.

      1) I feel like the conditions are ok. But I have never grown in India at the beginning of winter. It would be better if it was the beginning of summer. But I feel like you can certainly try since its still warm and sunny, as you say.

      2) Keep them in direct sunlight as long as possible. They need that direct light. All 12 hours would be best. It can’t be less than 3-4 hrs.

      3) They need water whenever the soil feels dry and warm. Small plants need only a little.m maybe every 2nd day. Big plants need a lot (daily). Don’t overwater, always make sure the pot you are using has holes at the bottom for drainage.

      4) The bigger your pot, the bigger your plant, the bigger your harvest will be. So use the biggest pot you can!

      Thanks for your comment and happy growing

      Jack
