Many people aren’t really sure when to plant their crop. When’s the perfect time of year to germinate your seeds so that everything runs as smoothly as possible? Well, this depends on what medium you’re growing in, the accessories and things you have at your disposal etc. You can grow the perfect crop at any time of year depending on how you’re doing it and what you have. Today we’re going to show you techniques so that you can get the absolute most out of your plants regardless of what time of year it is.

How and When to Plant Marijuana Outdoors

If you’re looking for normal marijuana plants (2m 500mg +/-)

When spring arrives we all know that it’s time to start germinating your marijuana seeds for your outdoor crop. It’s the most important crop of the year as it’s where you can get the most production of the entire year. Old school growers like to plant their seeds for the first full moon of March.

The reasoning behind this is so that while your seeds are germinating they’ll also have light at night time and they won’t stretch up too much in their first days of life. Sometimes it’s a bit too cold at that time though, and of course you can’t plant at the same time everywhere, we’re talking from a Spaniard’s point of view here. If you live somewhere with a very cold climate your plants will take much longer to grow and they’ll get stressed out from cold or wind, which will create weaker plants that are more susceptible to infestations and fungi.

The best thing to do in this case is to wait another month or two; a germinated seed in a decent climate from April onwards will actually be bigger and better grown than one planted in March in the same place.

Taking care of plants for such a long time is quite a lot of work for the grower, you need to keep an eye on infestations, fungi, nutrition, transplants, pruning, tutoring… The whole process takes about six months of constant work. If you’re looking for a decent product and yield, you’ll need:

  • Fertilizers for growth and flowering. You can use your preferred fertilizers, organic hummus, guano for growth, a booster for the flowers and a base fertilizer for flowering should be enough to get a productive and flavorful plant. If you use chemicals then you’ll need a complete range from a specific brand that’ll give your plants the minerals they need to make the most out of the flowers. Of course, chemical products reduce flavor but increase yield, whereas natural products intensify the flavor but make for a lower yield.
  • Insecticides for insects like white flies, mites or thrips. Preventive insecticides are recommended to avoid any scares.
  • An anti-fungi product that works well against oidium. Propolix or other chemical products work well, but you’ll need to use it from the start.
  • Bacillus Thuringiensis; this is used for caterpillars and other worms. Use it as soon as flowering begins, which is when these pests start to appear. Around May/june.
  • Stakes or wires to keep the branches up during the flowering period.

If you’re looking for small plants (1m 250g +/-)

If you’re looking for some small to medium sized plants, both compact and strong, then you’ll need to wait till around the middle of March to germinate your seeds. Your plants will have about a month to grow before the light period changes, and they’ll grow with more sun than other plants, making for strong and compact specimens. So, when they begin to flower they will be more compact, around 1m tall. You’ll need the same products as for large plants, as well as patience although less due to the fact that they take a lot less time, around three and a half months. This style is much easier for beginner growers, although you’ll still need to take care of them.

If you want gigantic plants (3m 1kg+)

To get these kinds of plants you’ll need to apply yourself to the job more than the other two types. You’ll need to grow plants with a decent size so that they can grow amazing 2m long branches in all directions with buds as thick as your fist that you’ll need to hold up with a SCRoG mesh so they don’t break.

If you’re looking to grow a plant of this size before June then you’ll need to grow it for at least six months so the plant has more surfaces to flower on, which should take another three months. You’ll get much better results if you plant straight into the ground rather than pots.

To be able to grow it for so long you’ll need to do so in a greenhouse. You’ll need to buy or make your own plastic greenhouse. In a greenhouse your plants can avoid the cold during the winter as well as receive enough light to grow properly. You’ll need to germinate your seeds in December. You should germinate them inside so that they don’t die off at the start and they can get a nice warm germination.

Then, you’ll need to make a hole around 50x50x50cm and fill it with new substrate so the plant has a decent medium to grow in. Once your plant has germinated and it’s a few centimeters tall you can officially move it to the greenhouse. You’ll need to install a light above the plant that should turn on for 10 minutes every four hours or twice a night so that it still grows during the winter. The light doesn’t have to be super powerful, the only reason we do this is to annoy the plant and keep it growing. Once the plant reaches around 40cm, you’ll need to start pruning it starting with the main calyx. Two or three weeks later, prune again on the higher branches, two weeks later another one… until after a couple of months you have a big ball of leaves full of mini-calyxes which will later grow into long branches.

More or less around February you’re going to need to place four stakes around your plant in a 1mx1m formation, with the plant right in the middle, and then place a SCRoG mesh over it to separate the branches as much as possible and as wide as possible. Once March arrives you’ll need to take the light away and let it get used to natural light and the growth period lighting (these dates are for Spain). Once you notice the good weather starting again, sometime near April, remove the greenhouse and let your plant breath fresh air. Your plant will be a meter tall, when everyone is is still germinating at this stage, which a whole lot of branches and prepared to grow for another three months. Once June/July arrives, your plant will be absolutely huge. Just before it flowers you can place another mesh so the branches can put up better with the weight of the buds. You’ll need to keep an eye out for infestations and fungi due to the size of the plant and how hard it can be to inspect all of it. It’ll need good nutrients due to how long it’s going to grow, and you’ll need to water it properly. You can get the entire years’ worth of gear in just one plant. Happy growing!

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

Saturday July 4, 2020

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 black market to an “essential” industry because of 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, no matter where you live in the country, you can start your own grow in a container as small as a flower pot. However, cannabis is a picky plant and will need at least four-to-six hours of light each day and a few months to produce its desired cannabinoid goodness, so there is some variability in the growing season depending on where you live.

B efore we move on, here are some date ranges to help guide your growing plans. When Spring Equinox comes around, start germinating your seeds. Make sure those plants get outside by Summer Solstice in June, and harvested around Fall Equinox. For more specifics, you’ll need a fortune teller. 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 for your outdoor cannabis grows, here’s a look at optimal grow times for regions across the U.S.

Northwest (Northern CA, OR, WA)

When you plant cannabis in this loamy region you’ll never have to worry about rain. However, mold development and lack of sunshine can make growing outdoors 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 when it’s time to get your plants outdoors is when daylight hours increase and the temperature starts to warm.

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

If you choose to grow your plants outside 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. Before moving your plants outdoors, make sure the last frost has passed

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 for growing outdoors since its flowering time is shorter. Try to shoot for germination after the final frost of spring has passed in these regions.

Northeast (NY, MA, PA, NJ, ME, VT)

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

Southeast (FL)

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 your plants outside.

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