How to grow weed outdoors – a comprehensive guide

Growing marijuana outdoors is often considered the most simple and natural method, as it replicates the way it has grown in the wild for thousands of years. This basic guide to on how to grow weed outdoors will provide you with the information to make the most out of what nature has to offer.

The benefits of growing marijuana outdoors?

Growing marijuana outdoors provides many of the expensive essentials that need to be paid for when growing indoors, free of charge. The sun provides the equivalent of 2000 watts of light per square foot and natural air provides a level of CO2 that is extremely difficult to manufacture indoors. Plants grown outdoors receive far more light which helps develop the buds growing at the bottom of the plant as much as those at the top. Although you don’t have the control of an indoor grower, successfully growing marijuana outdoors provides you with a much larger yield.

Where can I grow weed outdoors?

Successfully growing weed outdoors is dominated by climate, soil, and water supply, regardless of whether you are in your back garden, or in a remote mountain patch. In order to have a bountiful outdoor grow your plant will need at least 5 hours of direct sunlight a day.

Grow tip – If you’re growing weed outdoors check the light supply by standing in your chosen location. You’ll be able to tell if there are any light blockages.

Backyard Growing
Backyard growingGrowing weed outdoors in your backyard enables you pay close attention to your plants and have relatively good control over their environment. Prepare your soil in fall, removing weeds and digging beds for your plants, turning the soil. Cover your turned soil with mulch over the winter months to hold in the nutrients. You will be able to transplant your seedlings in April or after the last frosts.
Growing in pots
Growing Marijuana Outdoors in Pots
If you’re growing marijuana outdoors in pots, it’s likely that you’re growing on a terrace, patio, rooftop or balcony. If you have your pots in a high location, take precautions against strong winds, as these can dehydrate your plant and carry rogue male pollen.

Try to keep your plants out of prolonged direct sunlight as this may overheat the pot and destroy the plant’s roots.

Guerrilla Growing

Guerilla GrowTo put it simply, Guerrilla growing is farming outdoors away from your own property, mostly in a remote location where it is unlikely to be found. Security and location are considered the main factors for the guerrilla grower. It’s recommended that the guerrilla location you choose is remote, near a good water source, receives a good amount of light and is out of direct wind.

Grow tip - Guerrilla growing – take your water in a container that makes it look like you’re hiking.

Soil

There are many different types of soil with some being more suitable for outdoor marijuana growing than others. This basic guide on soil for your outdoor marijuana plants should help, regardless of your growing location.

Clay soil
Clay soil
– Prepare clay soil at least a month before growing by adding compost and manure or perlite. Clay soil holds a lot of water so can drown roots and suffocate your plant. Be sure to excavate deep, adding a lot of organic material to increase drainage and air circulation.

Sandy Soil
Sandy Soil
(Sandy Soil) – Marijuana plants can achieve excellent root penetration in sandy soil, but doesn’t hold nutrients well. Add compost and mulch or vermiculate to sandy soil to increase its water and nutrient retention.

Loam soil
Loam Soil (Loam Soil) 
– Loamy soil holds moisture well, has good drainage and is easy to work with and is perfect for growing marijuana outdoors. Loamy soil is dark, fertile and crumbly in the hand. Check the PH of loam soil as this varies and ideally, your soil’s PH should be between 6.5 and 7.5.

Grow tip – If you have poor soil for outdoor marijuana growing, dig holes that are 3 feet deep and wide, filling with a good compost or potting soil.

Water

Most of the water your plant requires will be provided by fresh rainwater. If your plants do not receive the water they need through natural means, it is up to you to supply it. Remember, the bigger the plant is, the more water it needs so keep an eye out for signs of under-watering. Plants will show signs of wilting throughout the hot summer month, but this is normal. If you get 1 inch of water a week, you won’t need to water your plant. There is more information in our water section.

Nutrients

Fertilizing your outdoor grow will help your overall final yield, especially if your soil quality is not great but be careful not to over fertilize young plants! Use a fertilizer high in nitrogen for the vegetative growth stage, changing to high phosphorous formula when your plant is flowering. More information on the nutrients can be found in our nutrient section.

Harvesting

Harvest your weed before the cold, damp weather of fall starts to set in. Many strains can take a short freeze, but sustained periods in temperatures below freezing will kill your plants. Harvest your guerrilla grow at night time to avoid detection. Information on when your plant is ready for harvest can be found here.

Choosing your weed strain

Not all strains are good when growing weed outdoors. Its important that you pick a strain that suits your outdoor growing environment. Use our outdoor weed strain collection to help you make the right choice.

Grow tip – When growing marijuana outdoors, germinate your seeds and start the seedling for 2-3 weeks indoors before transplanting outside.

What problems can you face when growing marijuana outdoors?

Growing weed outdoors will mean you have a lot less control over the environment your plants are in, which brings with it a different set of issues that may affect your plants.
Burst pollen sacks
Rogue Pollen (Bursts Pollen sacks) Pollen from rogue male plants or hemp can pollinate you female flowers. Although this is a difficult problem to avoid, there are measures you can take. June and July are when pollen levels are at their highest, so plant with the intention of flowering in August. Keep a close eye on the wind direction, and read pollen reports that are easily found online.

Pests and bugsPestsCheck your plants regularly for any damage from pests. Caterpillars, slugs and snails can eat away at your plant. Attracting birds to your grow using bird feeders will provide it with some natural caretakers.

Animals – Look out for any animals that may cause your outdoor marijuana grow some damage. Keep animals away from your plants with wire mesh. Avoid picking a place that is inhabited by deer and rabbits, as both like a nibble on growing marijuana.

Frost (Frost Damage) – Although marijuana is a hardy plant, it cannot survive long spells of temperatures that are below freezing. Avoid frosts by planting in April, choosing a strain that will go through a full growing cycle before the first frost come. Indica strains have a shorter cycle than sativas if local frosts come early.

Mould – As you can’t maintain the humidity or the amount of rain supplied by Mother Nature, keep a close eye on your buds for any mold growth. You can reduce the risk of mould by shaking your flowers out after any large rain falls. Remove moldy buds before they spread.

Learning how to grow weed outdoors will allow you to take full advantage of mother nature. The detailed guide above will have you successfully growing weed outdoors in no time at all.

    Planted White haze auto seeds directly into soil on 6th May. They germinated nicely within a week, outside in the Canary Islands but are showing flowers already, They are only about 6 inches high with four sets of leaves. Should I stop the flowering process or quickly pot-on into my prepped 10lt pots? We currently have 15 hours of daylight. Thank you and please accept my apologies for taking up your time. There is so much conflicting advice on line..I’m confused!

    Is it smart for me to guerrilla grow with the plants in pots instead of in the ground? What auto flowering strain would you most recommend for this? Also what are the chances that my freshly germinated seeds would die if I put them straight into their pots that they will spend their whole lives and never transplant them, is there something I can do to better guarantee their survival?

    Hi I’m a resident of Florida and we managed to get amendment two(legalized med. marijuana) on the November state ballot and it’s passage is looking very possible.I’m studying growing techniques and I’m wondering if I can grow marijuana hydroponically in a green house.I’m thinking that one could take advantage of the Florida sunshine coupled with the benefits of a hydroponic growing technique.Any thoughts on possible pitfalls of this “type of setup”?Thanks

    I have recently purchased the Garden Patch Growbox. I was going to grow in my small but private back yard. I get medical cannabis and it’s legal for me to grow. The Growbox is semi hydroponic with a water trough below the potting mix. 2′x8″ it has fertilizer for vegetables that slowly dissolves over a 4 mth period. I live in the desert and although it’s winter we have mild day time temps 50s to 70s and al least 5 hrs of sun. I’m wondering if I plant small plants purchased from the local dispensaries if I can grow them successfully in this climate. And how many could I place in one planter.
    Thanks

    Light is essential for marijuana plant growth so if the location doesn’t have access to light it’s going to be difficult to grow the plant. Also the idea of growing marijuana outdoors is that you use the natural sunlight rather than lights.

    It is possible to grow marijuana seeds outdoors without starting them off inside. We would always recommend germinating using paper plate method outlined here as you will have a much better success rate. It is possible to plant seeds direct in the soil you just need to be careful not to over water and not to sow them too deep otherwise there is a high chance the seeds will die.

    It could be for a number of reasons but it’s most likely to be either a nitrogen deficiency or over fertilizing your marijuana plant. Also as you approach harvest the leaves will naturally turn yellowish/brown as your plant uses up it’s nutrients to produce resinous buds. There is a section in the troubleshooting page that covers Leaves you can find it here.

    has any one try some Epsom salt in the ground when planting new plants outside ?
    I was told this will help keep some pests away as well help the roots grow stronger and bigger and better plants. I have clay soil were I live and I also live right on the beach, So I have to worry about the salt from the ocean. That’s why I am asking the question and yes I am a first time grower. not doing to good get the plants to grow inside but when placed outside with in a few weeks all are dead. The temp is about 25 to 35. I have try to put them in the sun and gave them shade but nothing seems to work I might to just keep them inside or not grow any at all. I have heard growing pot is as easy I can not tell I must have planted at least 50 plants and not one lasted past one month. can some one help a poor pot smoker with some help.

    Hi there, it’s always best to start seeds indoors and move them outside. Follow the germination example in our Germination section. Once seeds have sprouted the seedlings then need to be left indoors under lights for 2-3 weeks until they are strong enough to be moved outside and transplanted.
