Many of us in America didn’t have a real winter this year, and if climate scientists are correct, we’re heading towards a drier, hotter, “three-seasons planet.” This has major implications for outdoor medical marijuana growers…especially if you grow in remote locations away from municipal water or a reliable well.
These warmer than average temperatures, winter tornadoes, early spring, and bizarre precipitation patterns means our outdoor marijuana gardening calendar is accelerated by 2-6 weeks. Outdoor growing is going to be harder. The ground is drier, and there’s less likelihood of seasonal streams and other natural outdoor water supplies because snowfall has been abnormally low.
These harsher conditions require you to armor your crops more than you might have in the past. Look for my upcoming article on how to do that.
Before climate change, outdoor medical growers started their plants in greenhouses or indoors in late February and March, hardened them off, then transplanted them into full outdoor terrain in April or May.
Today, I know growers who start their outdoor plants as early as December; some of them put their crops into the ground long before the spring equinox, which occurs around March 21st in the Northern Hemisphere.
The big problem with that approach is that the three-seasons planet’s early transplanting temperature advantages don’t coincide with the sun’s day-length. Things are out of sync.
Many strains of outdoor marijuana will be confused by improper daylength if you put them outdoors before visible light duration is at least 13-14 hours long. Your plants also get confused if daylength isn't increasing at all or at the right rate (such as between summer solstice and the spring equinox).
In general, growers have been advised by seed breeders and marijuana grow gurus to match their cannabis genetics and outdoor planting times with the latitude of their location on earth. The latitude is one major factor that indicates length of visible light.
If plants are put outside before the daylength is of long enough duration and is increasing, they won’t think it’s “grow phase." They may even start pre-flowering, then get completely messed up (go hermaprhoditic, or revert poorly to veg growth) when April turns to May and the plants realize that it's spring and summer they're looking at, not fall and winter.
If it's a little confusing, forgive me, but think how weird it feels for your marijuana plants. In general, I advise that you contact whoever bred or provided the strains you're growing, and ask them for guidance on when to put them outdoors. The generic advice is: put them out after March 22, but only after all chance of frost has passed. Given that it's 15-25 degrees Fahrenheit above average temperatures as I write this article in early March, 2012, I don't think most of us are going to have to worry about a late frost.
And over the next few weeks, look for this series of articles on outdoor growing. We’re bringing you the latest tips and technologies for outdoor growing. I'll try to also make clear the differences in tactics and logistics between growing marijuana in your back yard versus growing marijuana in a remote "guerilla" location.
For now, I give you recommended premium, phat-bud, THC gooey outdoor strains so you can order great seeds and get them sprouted. These are high-yielding, professionally-bred, ultra-potent outdoor marijuana varieties that can handle the hardships of being outdoors:
Arjan’s Haze #2, from Green House Seed Company: Arjan has given us three different “Ultra” Haze varieties. His UH #2 is my favorite for outdoor growing, in part because the other two UH’s aren’t as good outdoors as they are indoors. UH #2 grows very tall and ripens in bloom phase for up to three months. If you give Ultra Haze #2 unlimited root space and you're growing it in a temperate, “Mediterranean” climate, you’ll see untrimmed plants as tall as 15 feet! Imagine the yields!! Expect that classic Haze high that contains a significant amount of body stone. You increase yield by harvesting individual buds and branches as they become fully ripened, allowing other buds to continue development until late October or even November.
Lemon Skunk, from DNA Genetics: You can grow this citrusy babe indoors too, which means some growers take clones of the outdoor plants as soon as they show sex, turning them into motherplants or an indoor sea of green. This increasingly-popular variety is slightly Sativa dominant, but its Indica genetics means you can harvest around 7-9 weeks in bloom and get peak THC, taste and aroma. The lemony tang is one of the main reasons people grow this variety, which commands high per ounce prices.
Grape Krush, from DJ Short: From the originator of the Blueberry marijuana lines, DJ Short’s Grape Krush has a very strong smell, which means you have to be careful about where you plant it. Grape Krush is a heavy yielder, especially if you pour on the nutrients and give the young plants an early topping to encourage more diameter and less height. One thing that’s very strange about this variety: the high doesn’t hit you in the first ten minutes, it takes a while. So be careful when you’re just starting out testing this bud, because you might think it’s not gonna come on, but then it does, about half an hour later. Expect to harvest in September or October in most locations, with a max of about 9-10 weeks in bloom .
AutoMazar, from Dutch Passion: Autoflowering marijuana is the latest cannabis revolution, and you’ll see more autoflowering articles from me because I am testing auto marijuana strains and so far the results are very impressive. AutoMazar and other outdoor autoflowering marijuana offers you great value: your plants will finish in 80 days or less, from sprout to harvest. For AutoMazar, this means you could sprout your seeds in early May and harvest in August. Until a year ago, autoflowering varieties didn’t have the stony potency that regular marijuana has. But that was before companies like Dutch Passion figured out how to make autoflowering marijuana just as potent as regular marijuana. AutoMazar grows best in a warm climate, and because it has only a short time in veg before it automatically starts flowering, you have to be totally pro about feeding and tending your sprouts properly so they develop optimized root systems and branching structure fast. European growers have gotten as much as 270 grams dry weight from one AutoMazar plant, which puts its yield on par with regular cannabis.
One other way to get great marijuana genetics is if you know people growing outdoors where you’re located and you’ve seen their plants outdoors and smoked their weed, verified that their plants break out large amounts of stony bud while also being resistant to any molds, mildews, pests or other conditions common to where you want to grow…get yourself some of those as clones or seeds, and get your outdoor season started!
If you’re doing a remote marijuana grow, stock up on Heavy Harvest, the only marijuana outdoor feed program that gives you once-per-season, timed-release nutrients designed for marijuana in a spring-summer-fall format. I don't know how the manufacturer did it, but they coated these ferts with something that properly releases doses of season-specific nutrients so your outdoor marijuana plants get fed not too much not too little but just right throughout each season.
The Heavy Harvest suite of fertilizers is an important tool that protects your plants and you. Instead of you having to crawl through the bushes to do multiple feedings, or trying to mix liquid nutrients outdoors and apply them, this once-per-season outdoor fertilizer program feeds your medical plants customized nutrients that correspond to their seasonal needs, the easy way.
With extra drought stress, heat stress and other insane climate change factors making it harder for your outdoor medical marijuana plants, proper nutrition provided by Heavy Harvest is more necessary than ever.
What's more, you can use other hydroponics products to enhance your outdoor crops...look for info on this in my future maximum yield outdoor marijuana growing articles.
The only downside to Heavy Harvest products is they'll make your plants produce much heavier harvests, so you'll have way more poundage of medical bud to cut, transport and trim. Your muscles will be sore from cutting and lifting buds that are in some cases wider in diameter than baseball bats, and as long.
Consider the Trim Reaper bud trimming machine...it saves your fingers and you don't have hire extra manicuring personnel. Because your harvest is going to be bigger than ever!
With climate change giving us an early spring, less rainfall, more extreme weather events, and a longer growing season, it’s time to get started on planning your outdoor medical marijuana season now.
