when to plant marijuana seeds outdoors

You’re not the only one wondering when to plant Marijuana seeds outdoors. Although it is a question that doesn’t have only one answer. Depending on what part of the world you live, the ideal conditions to plant marijuana seeds outdoors would be in the spring, between March and May (in the northern hemisphere). Ideally, during this time, your marijuana seeds should already be germinated and you can even plant marijuana seedlings that are a few weeks old outdoors. As we have mentioned in our other guides, to plant marijuana seeds outdoors is a numbers game. The more marijuana seeds you plant outdoors (if you don’t have the experience) the better your germination rates and eventual harvest will be. For Northern hemisphere climate conditions we don’t recommend to plant marijuana seeds outdoors, rather germinate and start growing the marijuana plant indoors until the weather conditions are ideal to take the marijuana plant outdoors.

If you live in a place that has a constant good weather then the season isn’t very important to take into consideration for you to plant marijuana seeds outdoors. In places with less abundant sunshine, the season would last roughly from March to August or September depending if it’s an Indica or a Sativa marijuana plant. In other regions such as equatorial or coastal regions, the issue of when to plant marijuana seeds outdoors is non-existent since the constant warmth and humidity will germinate the marijuana seeds outdoors without any worries of the conditions being too harsh for the seedlings, or not enough humidity and warmth for the marijuana seed.

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.

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.

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.

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!

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

Such cold temperatures can kill seeds, so the best bet is to germinate them inside until the late snow passes. If you’re only growing a few plants, this can be done in front of a sun-facing window. If you want to grow a lot, though, you’ll probably need to buy a growing light. Then transplant those baby weed plants outside before the summer solstice on June 20 (start watching weather forecasts after Mother’s Day). And go with a strain that has a short flowering time — because Colorado’s unpredictable snow usually returns in October.

Dear Stoner: I want to throw some seeds in the ground in my backyard this year. Should I do it at the same time as my other plants and flowers, in April or May? Earlier? Later?
