About Growing Marijuana Outdoors 2017-05-04T03:38:57+00:00

Growing Marijuana outdoors is a great way to make your own quality pot.

It is inexpensive and no special equipment is needed. Outdoor plants can become large and yield huge harvests.

Here are tips on how to successfully grow Marijuana outdoors.

By the way: While growing Marijuana outdoors is easier in a warm and sunny climate, such surroundings are not absolutely necessary.

I have had great results in cold northern Germany, in my parents garden. That’s where most of the pictures in this site have been taken.

But of course, if you live in Australia or other sunny parts of this world, growing marijuana outdoors becomes a bit easier.

So, how to set up an outdoor grow?

Use an outdoor Cannabis strain

There are strains available that have been breeded especially for outdoor cultivation.

These strains finish earlier. They do not need that much time to get to the flowering stage. Also they might be more resistant to humidity and mould.

To find out where to buy Marijuana Seeds, please read Marijuana Seeds.

Start in Spring

The plant has a lifecycle. It will grow tall in spring and the first half of summer.

Once the summer solstice has passed, the female plants will grow less but put its energy into flowers (smokeable buds).

In Australia and South Africa for example, Spring is in October. In Germany and The USA it is late March.

Find the right spot

Your Plants need at least 4 – 6 hours direct Sunlight per day. The more light, the more weight you’ll get at the end.

The grow spot should be well hidden. And keep in mind that you might need to bring water in case its a dry summer.

A garden can be a great place for growing Marijuana outdoors.

By putting Marijuana Plants into Pots, you can move them around. That makes it easier to hide them if necessary.

By the way. Cannabis ‘mixes’ well with other plants. If you put a cannabis plant between some other large, leafy plants, it becomes much harder to spot.

One day, I showed a good friend of mine a cannabis plant in the garden. That particular plant was standing between other leafy plants.

And although we were standing right in front of the green lady, my friend could not see it.

It was only after I assured him that it is there, he suddenly saw it. “Oohh! I did not expect it was that close!”.

Here is a pic of that plant:

Pot mixes well with other plants and is than harder to spot for the human eye!


Another great spot to grow can be a balcony or a terrace. I have had a nice harvest with my “Balcony Grow“.

Germinate the seeds

A good time to put cannabis seeds into soil is at the beginning of spring. As a rule of thumb, I try to always germinate 2-times the amount of seeds than plants I want to grow. Some may not germinate and or some will be male plants. More on that later.

Germinated Baby Marijuana

Here in Australia, spring is in November. In the States, it is somewhere March to April.

To make sure all your cannabis seeds germinate properly, read “How to Germinate Marijuana Seeds“. A healthy start into life will result in a healthy plant.

Baby Marijuana plants are more likely to be eaten by snails and not very resistant against cold and humidity. They should be kept inside, e.g. on a Sunny Window board, for the first 3-4 weeks of their live. I have many people commenting that they put their young plants outside only to have them eaten by something (Horses, Snails, Kangaruhs, Dropbears). It happens easily. Plants should be relatively big before putting them outside.

When they have grown to a stable plant …

Put the Plants outside

Plants can be put outside 3-4 weeks after germination. Temperatures outside may not fall lower than 0 deg Celsius or 32 F. Or the plants will die.

Young Marijuana Plant in Pot outside

I find it a good idea to grow in Pots. You can than move the plants around. Either to hide them or to “follow the sun”.

Wherever you put it, in a pot or directly into the ground, make sure you use good quality soil.

Quality soil has a dark, almost black colour. It contains some fertilizers and perlite (little white pearls).

If there is quality soil in your garden already, good!

But if you are unsure, buy good potting mix. That will increase your results. To make it even better, mix some perlite (little clay pebbles) into it.

Marijuana likes light, fluffy soil with loads of ‘food’ in it. Do not apply pressure to the soil. The roots need oxygen to function properly. The perlite helps here.

When using plastic pots, you could drill plenty of little holes into them to let some air in. I very much recommend fabric pots. The bigger the pot, the bigger the plant. 7 gallons is a good size for outdoor plants.

Fill your pot with the same soil as you plant already used in its little “Baby pot”.

If you prefer growing Marijuana outdoors directly in the ground, make sure the area where you put it offers good soil.

It can be a good idea to dig a hole of ca. 60 cm (23 inch) diameter and depth. Than fill it up with quality flower soil and plant the weed into this soil.

Remove any other plants around that could interfere with your Marijuana or grow over it. Cannabis needs as much sun as possible.

Once you’ve done all that …

Let the Plants grow!

The plants now do pretty much all the work.

The more sun they’ll get, the faster they’ll grow.

Water the plants regularly. Do not overwater. Give only as much water as the plant can use and only when the soil has dried up. Touch the soil with the back of your fingers. If it feels cold, there is still water left in the soil.

After 3 – 4 weeks, you want to start using Fertilizer. Up to this point, the plants were feeded of the nutrition in its soil.

There are different Fertilizers available. Some are made especially for Marijuana, for example this one.

These are the best to use because the composition is targeted at the needs of cannabis.

But if you want to save some money, Tomato Fertilizer works well, too. But make sure any fertilizer you use can be used for Food Plants.

Stick to the dosage recommendations written on the fertilizer container.

Do not use too much Fertilizer. It will harm or kill your Plant.

If you are like me, you probably watch at your marijuana plants every day.

If the leaves start becoming light-green or yellowish, give some more Fertilizer.

Remove the Males

At some point in time you want to remove the male marijuana plants. They do not deliver those tasty buds. They seem to have lower THC Levels generally.

If they are not removed, they will pollinate the females.

Once the females were pollinated, they put their energy into developing seeds.

The buds won’t grow that much anymore and the possible harvest decreases. Plus its a bit annoying to smoke seeds.

How to spot a male plant?

There is no way of telling before the plant starts budding.

The following is a picture of young male buds. They look a little like ‘balls’.

Male Marijuana
(above: Male Cannabis Bud)

Female Marijuana
(above: Female Buds have white ‘stigmas’)

If you spot a male pull it out and remove it. Its always a little bit sad.

Usually, there is a 50% Male – 50% Female gender ratio.

Once you got only females left, it will take 2 – 4 month until ….


Your plants will be ready for harvest at the age of 3 – 5 Month.

In the last weeks of a plants life, make sure to check the buds for mould. Especially if you grow in humid environments.

Mould looks gray, you can see it when bending the buds and looking into their inner.

You can tell that the plant is ready when it has nice, big buds.

It will not grow that fast anymore and most of the stigmas on the buds will have turned brown.

At his point, you can finally harvest the fruits of your work. Growing Marijuana outdoors can bring huge harvests.

Please refer to my article harvesting Marijuana for a successful harvest.

Well and after you dried and manicured your Pot, it will look something like this:

2.5 ounces dry from 1 plant.

    Hello all, I’ve got a little problem, any insight or ideas are appreciated.. So I’ve got two plants that are almost ready for harvest but I have been dealing with a bug problem for months now. I’m growing outdoors, near San Diego, CA so we’ve had good weather all spring and summer, but bugs are an issue. A friend recommended mixing Neem oil with water and spraying the plants, and it’s helped a little but when I look closely I still find bugs. My question is, is it safe to smoke these trees even if they’ve had bugs, possibly (spider-mites) getting at them? Also, if anyone has any tips or suggestions on harvesting when you’ve had bug problems please send ’em my way. Help a noob out! Stay irie, my friends…

    • Hi,

      I can only recommend Neem oil.

      It works, but may need several applications.

      You could use stronger pesticides, but since the plant is to be consumed I wouldn’t.

      Here is a good neem oil product which will kill the bugs: http://www.how-to-marijuana.com/go/neem/

      When you apply this:

      – Spray only in the evening when the sun is going down. (no direct sun)
      – Aim especially for the leaf undersides. That’s where the crawlers sit.
      – this neem product is a concentrate. Mix with water before spraying!
      – repeat a few times.

      It will not be bad for you to smoke the bugs. But it won’t be nice either.
      Also, if spider mites get the upper hand, they will wrap your plant into a giant net and it won’t survive.

      Cheers, Jack

    what causes leaves to turn yellow and brown?

    • There are different reasons.

      Most of the time, it has to do with fertilizer:

      Not enough fertilizer
      This will cause leaves become bright-green to yellow. Starting from the lowest leaves going up.

      Too much fertilizer:
      Leaves roll up and can get brown spots.

    this is my first time does this look about right it has allmost2and a half three months left of decent weather and is the purple normal or do i have a defeciency growing outdoors in 5 gallon pot? what you think jack hows it look? love your site and really respect your opinion ty

    • jayaday

      no one got any help for me on this jack maybe!?

    • Hi Jay,

      thanks for uploading photos.

      There is something not quite right. They are too purple and also the leaves are curling up.

      I wonder if they are overfed. Are you giving fertiliser? – Let me know. You may need to slow down and flush the soil.


      • jayaday

        no havnt been feeding at all in past month or two pure water i thought the same thing and quit feeding with nutrients

    Hey guys so I threw about 20 seeds down in my backyard. I’ve had the seeds for a while. I just been collecting them over time from different buds I got. Sometimes I got like one or two seeds in an 8th etc. anyways, so I decided to just throw them in the ground. Idk why I though they weren’t going to grow but they did. I think I put them too close together though. So idk what to do now and like if I should start fertilizing or what? Im in the northeast so I think I may have to bring them in. They have been growing for about 3-4 weeks I believe. I have not watered them and just let nature kinda do it all lol. Anyways some input would be greatly appreciated. Here are some pics

      • Hi,

        thanks for uploading photos.

        These would grow if you have enough summer left.

        They are not too close together, this is fine.

        They look like they need some water.

        Fertiliser is not needed yet. There is enough in the soil.

        I am not sure how much summer you have left. But I assume it is a bit colder and wetter where you live. So these may not end up going all the way to harvest.

        Unless, you dig them out and put them under a lamp indoors.

        I don’t recommend you do that though, because many things go wrong when digging out plants. Usually roots get damaged and the plant dies.

        So for these, I recommend you leave them where they are. Give them some water. And maybe protect them with some chicken wire. These small plants outdoors get eaten all the time. Then see how far they will go.

        Maybe, if you’re lucky, you can harvest a bit.

        And if you wanna grow indoors, start with fresh seeds and with a good lamp. That will bring you the biggest harvest.

        Happy growing,

          Hey Jack,

          Thanks a lot for getting back to me. Our Summer’s sometimes can go as far up until mid late September. Currently we are almost in late August and we are seeing temperatures in the high 80s, with a sunrise at 6am and sunset close to 8pm.

          I’m going to leave them put, as I am afraid to damage the roots. I will though, grab some chicken wire to protect them. My husky may try and get a nib out of them lol

          Around what time frame should I start to fertilize them?

          Also do you have a guide for indoor growing and a good guide as to where I can get the lamps, etc? any reputable links for seeds? I’m a bit afraid to shop for this stuff on random sites.

          Thanks a lot for the help!

  • John

    • John

      This is the base of the plant

    • Hi,

      looks very healthy and perfectly well.

      Good work.

      Thank you for uploading the photos.

      Just let it have as much sun as you can and give fertiliser as you probably do.
