Best Time To Plant Cannabis Seeds

If you are thinking about cultivating cannabis, one of the first things you will need to determine is if you should cultivate outdoors. There’s only so much Netflix you can watch. Grow a pound to save money and stay sane during long bought of self-isolation from covid19. With the summer growing season in full swing, many of you have reached out asking what's the optimal time to start an outdoor cannabis grow. Check out some recommendations based on different regions where marijuana cultivation is popular.

When is the best time to plant cannabis outdoors?

A number of states now allow cannabis cultivation for adult use, and even more states allow cannabis cultivation for medical purposes.

The increase in cultivation reform has resulted in a rise in interest in growing cannabis among cannabis consumers.

Cultivating cannabis can be one of the most rewarding activities that a person can do, and with a pleasant reward at the end of all the hard work (assuming the cannabis is grown right).

If you are thinking about cultivating cannabis, one of the first things you will need to determine is whether to cultivate cannabis inside or outdoors.

Why cultivating cannabis outdoors can be better than growing indoors

Cultivating cannabis outside has the following advantages over cultivating cannabis indoors:

  • Reduced equipment costs
  • No increased electricity bill
  • Larger harvest
  • Lower carbon footprint
  • Often easier to incorporate organic cultivation methods
  • Cheaper nutrient/input costs

Growing cannabis indoors has its benefits too, but for people that want a lower maintenance garden, cultivating cannabis outside is the way to go.

An obvious question – when is the best time to plant cannabis outdoors?

One of the first things that a grower needs to determine when planning a sun-grown garden is when to put plants into the ground.

A one-size-fits-all approach does not work. A number of factors are involved:

  • What is the latitude of where the garden will be located
  • What is the altitude of where the garden will be located
  • What is the precipitation level where the garden will be located
  • What will the temperature be like while the plant is in the ground

Ultimately what a grower needs to try to avoid is planting the plant(s) too early in the year, which could result in the plants dying due to the soil/air being too cold.

Also, the grower needs to avoid planting the plants too late in the season so to ensure that the plant(s) has enough time to go through a full growth cycle.

Generally speaking, you want to plant your plants in the ground outside in early to mid-May, similar to when it’s recommended to plant tomatoes.

Tomatoes do not grow exactly like cannabis, but for planting purposes, they are almost identical. With that being said, each part of the country is different.

A great resource to look up the recommended planting date for where you live is the Farmer’s Almanac.

Simply enter your location and it will tell you when is the best time to plant tomatoes outside, which can double as the date for when to plant your cannabis too.

Getting started ahead of time is key

If you are growing from seed, you will want to germinate the seeds at least 6-8 weeks before planting.

A way to cut down on the prep time is to use a clone if you are able to. Clones are often harder to find than seeds. Each route provides its own advantages.

Growers can get a head start by letting their plant grow indoors for a few weeks prior to putting them inside. This obviously requires a greenhouse or indoor garden.

By allowing your plant to grow in a controlled environment while the air and soil outside is warming up, you give your plant some additional growth time, resulting in a larger plant.

Other tips that can help

If you live in an area where the warm season is shorter than in other parts of the world, there are two tricks that can really help.

The first is growing your cannabis plant in a container rather than planting it into the ground.

This allows you to move your plant to the most favorable parts of your yard to get the most sunlight as the season goes along.

Putting your plant in a container also allows you to bring the plant in at night when the temperature drops below a desirable threshold.

The second tip is using a concept known as light deprivation, or ‘light dep.’ This method involves cutting back on the sunlight time that a plant receives by cover the plant up after 12 hours of sun.

It’s a tricky method that requires using a tarp over a greenhouse or building a box that can go over your plant.

When you first plant your cannabis plant outside, the amount of daylight at that time is usually around 14 hours.

As the season goes along, and your plant is big enough, you can cap the amount of light it is exposed to at 12 hours and your plant will start to bloom faster than it normally would, thereby helping your harvest come sooner.

5 reasons why it’s the perfect time to start growing cannabis

Right now, all across the US, the President, state governors, and local officials are ordering everyone to go home and stay there. They’re trying to prevent the spread of COVID-19, which threatens to overwhelm the US healthcare system in the coming weeks.

Millions of Americans are taking mental inventory of their preferred indoor hobbies.

Trust me, Leafly’s California editor: Cannabis gardening should really be at the top of the list.

Starting a March garden benefits from perfect timing, low costs, and easy logistics. You can keep it simple, or go PhD-level deep into the hobby. And it can provide real mental health benefits.

Here’s five reasons why gardening is the way to go right now.

Self-isolating? Order cannabis online with Leafly Pickup or Delivery

The timing is perfect

Let’s face it: chances are, the government has already ordered, or will order you to stay at home for the coming weeks.

You can’t spend all day fearfully checking Twitter and spinning out.

Now is literally the best time of the year to start that special houseplant you always meant to. That’s because cannabis is a fast-growing annual weed that naturally germinates in the spring and flowers in the fall in North America.

For outdoor crops, February and March are the best months to acquire and germinate cannabis seeds in order to maximize a harvest. You can nurture the plants indoors, then transplant them outside in May when the ground is warm enough and the nights are short enough. They’ll grow big and tall through the fall.

For indoor growers, starting in March means finishing as soon as June or July. That’s awesome, because you’ll have herb for the summer!

Save money growing exactly what you want

Everyone loves to complain about the cost of cannabis. Well, grow your own pound and save a few thousand dollars this year.

The sun is a free source of power. One fully grown outdoor cannabis plant can potentially yield a pound of dried, cured buds. That’s enough flower to keep a one-gram-per-day gardener baked for more than a year.

Your crop will be as cheap as seeds, soil, water, and patience. If and when you do need equipment, the costs will pay for themselves over future harvests.

A home garden is also the best way to ensure your cannabis is organic. You can explicitly control what you spray or don’t spray on your plants.

And only you know your favorite strain of weed. Grow a pound of that! Even better, grow two personal favorites and cross-pollinate them in early fall. Boom—a personal designer cultivar for 2021.

You don’t really have to leave your house or yard

You don’t really need to leave your house to grow a dank pound. Many folks have gardening gear lying around.

You can order seeds online and from local licensed cannabis stores. Some of those stores deliver, or offer online ordering and pickup. Gardening equipment can also generally be ordered online, including soil, cups, dirt, lights, containers, pots, nutrients, and the like.

I’m currently firing up Black Dog LED’s all-in-one, professional-grade indoor grow kit, which starts at $2,194.53 with free shipping. The kit contains everything but the seeds, down to the duct tape—so you never have to live-action role-play the film Contagion at Home Depot.

We need hobbies today

There’s only so much Netflix you can watch.

There’s only so much Netflix you can watch.

We’re all going to need a bunch of hobbies while we’re dealing with self-isolation. You can’t spend all day fearfully checking Twitter and spinning out.

A bit of gardening every day is a great way to focus on the now. Focusing on the needs of others, including your plants, is a healthy, productive way to lose yourself for a bit each day.

Read gardening books like Leafly freelancer Johanna Silver’s new book Growing Weed in the Garden, and Marijuana Harvest by Ed Rosenthal and David Downs. (That’s me.)

Stocking up on legal cannabis? Leafly has all your local menus

You’ll have to find a space, source supplies, and make a plan.

Make and keep a grow diary to set goals and track progress.

Join a new online community. Share your project online in forums, and get help with questions. Ed Rosenthal likes to say that cannabis isn’t addictive, but growing it can be.

The plants are different every day, and their needs change. You can name each one and give them the kind of personal attention a factory farmer never could.

Some days, the plants drink more. Other days you can almost watch them grow in real time. Pore over every detail of each seedling, making sure there’s no bugs, and they have enough light.

Now more than ever, you have the time. Plant a garden, and you will live in better rhythm with night and day, the seasons, the weather, and the soil.

Mental healthcare for the months to come

On the secret of life, French Enlightenment writer Voltaire once wrote, “Happiness lies in the cultivation of a garden.”

As I type this, over in the corner, underneath a windowsill, sit six Supreme Diesel seedlings (a mix of Jet Fuel Gelato and Sour Diesel, from Compound Genetics of Portland).

They bask in the weak winter light. Two compact fluorescent bulbs augment the sun. The seedlings’ stalks stretch to the light. Their first serrated leaves grow larger by the hour. One little girl needs help ditching her seed shell. A tiny gnat needs killing—bastard! One seed cup could use a little more soil. An hour just flies by.

Growing plants gives you something to look forward to. And, come on—we need something to look forward to right now.

When you pop new cannabis seeds, you can’t help but say a hopeful little prayer. Every gardener has a version of it, probably ever since man began agriculture.

To plant is to hope and keep faith with the cosmos. Hope for a fruitful future. Faith that it’ll happen. So many things remain beyond our control. Every gardener, no matter how agnostic, prays for sun, curses pests, and gives thanks at harvest.

Sowing seeds today is a physical, intentional way of saying: “There will be a tomorrow. The seasons will turn. The problems of now will not be forever. We will work through this. This too shall pass.”

What’s the Best Time to Start an Outdoor Cannabis Grow?

I t’s amazing how quickly the world can change, isn’t it? In the past 25 years, cannabis has moved from an illicit substance relegated to the shadowy corners of the illicit market to an “essential” industry amid COVID-19. In many states, local cannabis laws allow you to grow your own, and why not? When you grow your own, you can do your own quality control, know the purity of your product, and manage your own supply.

Luckily, you can start your own grow in a container as small as a flower pot. If you’ve got some space in your yard to grow weed outdoors, even better. So this may leave you wondering, when should I plant my cannabis outdoors? Luckily, there are some general date ranges to help guide your growing plans.

Regardless of which climate you’re starting in, when Spring Equinox comes around, start germinating your seeds. Make sure those plants get outside by Summer Solstice in June, then harvested around Fall Equinox.

For more specifics about how to protect your outdoor cannabis grows from the elements or whether you should grow indoors, outdoors, or in a greenhouse, check out the linked articles. Better yet, look into a book by celebrated cannabis growers like Ed Rosenthal’s Marijuana Grower’s Handbook, and of course, every green thumb’s favorite, The Farmer’s Almanac.

For a (shallow-ish) deeper dive into what to expect when growing cannabis outside, here’s a look at optimal grow times for regions across the U.S.

When to Grow Weed Outdoors by Region

Northwest (Northern CA, OR, WA)

When you grow outdoors in this loamy region you’ll never have to worry about getting enough rain. However, mold development and lack of sunshine can make growing outside a more difficult proposition.

Hybrids that flower earlier are suggested as the most successful grows, especially in Washington and Oregon. California plants can be put in the ground earlier due to the region’s warmer weather. Your best clue indicating that it’s time to start your outside grow is when daylight hours increase and the temperature starts to warm.

Midwest (IL, MI, Eastern CO)

This region is tricky because the weather is highly variable; rainy and muggy, and/or hot and dry. Winter may come early to this region, so choosing an indica-dominant hybrid strain might be your best bet, since their flowering times are shorter. Try to shoot for germination after the final frost of spring has passed in these regions.

Northeast (NY, MA, ME, VT)

With its rich soils and abundance of water, the northeast region can be a great place to grow cannabis outdoors, especially if you choose an early harvest strain that can finish up before fall kicks in. The best time to move your plants outside in this region is the middle of April, when days are longer.

Southwest (Southern CA, NV, AZ, NM, CO)

If you choose to grow outdoors in this scorching climate, be prepared to pay attention to the temperature, where highs that regularly exceed 100 degrees Fahrenheit will slow your plant’s growth. Sativas and sativa-dominant hybrids do well in this environment because of their lineage tracing back to the equator, where the weather is uniformly hot.

However, the dryness of the region means you’ll also have to carefully monitor your watering routines. Before moving your plants outside, make sure the last frost has passed. This last note is especially important in this region, as sudden, sporadic snowfall is common, so keep an eye on the weather.

Southeast (FL)

Though home cultivation is not yet allowed in the Sunshine State, many new medical producers getting into the industry are starting to grow outdoors, and there are a few things to be aware of if you’re licensed in the industry. The temperatures in Florida might be good for cannabis growing, but the humidity definitely is not.

In fact, because of all that moisture in the air, it’s best to avoid indica strains and grow sativas instead to avoid the mold that inevitably comes along with humidity. In this region, you could start the germination process as early as February. Just make sure that the last frost has passed before moving plants outside.

Conclusion

Of course, there are many different factors that go into the timing of an outdoor grow, and the weather will shift year-to-year. Use these estimates as rough guidelines and adjust as needed. Happy growing!
