Factors for growing cannabis outdoors

First of all, it is important to have a solid understanding of the climate features in your area. Cannabis plants are highly adaptable to basically any conditions, but they are still quite receptive to extreme weather changes. For instance, too high temperatures might cause your herbs to stop growing, when the low temperatures will also do massive damage and can result in the death of plants. Intense showers and strong winds may cause a good deal of damage to even the thickest plants and reduce your yield and, finally, excessive watering will lead to mold, especially during the flowering period.

Apart from the weather patterns, you have to realize how the day’s length might change seasonally in your area where you live.

The most useful tip on how to consider the climate changes in your region is to get a special climate zone map, which contains multiple aspects like elevation and proximity to major water objects. It will also be a great idea to utilize local resources, as some of the experienced gardeners in your region could share some extra knowledge of how to grow different sorts of flowers and vegetables that, in its turn, might be applied to cultivating cannabis. What’s more, if you can boast having special gardening and growing experience, you can also find growing weed outdoors a pretty easy and hugely enjoyable endeavor!

Benefits of growing cannabis outdoors

1. Energy saving

Even if you don’t really care about your financial spendings, the price of growing cannabis plants indoors can add up quite much in terms of double-triple times increased power consumption for LED lights and several fans. Outdoor marijuana garden does not require any special electrical equipment to be able to grow, thus, greatly reducing your costs and the overall impact on the environment. In fact, up to 9% of California’s electro energy is spent yearly on marijuana cultivation. Can you ever imagine how much of the natural resources are used for that purpose?!

2. Healthier plants

The herbs grown outdoors tend to receive much more than totally free sun energy to grow. Being cultivated with an access to natural air will provide the most effective circulation for the entire plant and makes it less susceptible to all kinds of pests and diseases. Active outdoor air circulation can help the plant develop stronger branches as well.

3. More potent buds and their greater quantity

Even extremely carefully grown indoor cannabis plants cannot be compared to their much healthier outdoor relatives in terms of yield’s amount. Well-conditioned outdoor plants, cultivated in compliance with all the requirements for an optimal growth, can make use plants produce 3 – 4 times more qualitative final product than those grown indoors. Speaking of marijuana flowering time outdoor cannabis also appears to have a slightly longer growth cycle, but results in higher yield.

4. Fully natural

Even the most expensive light equipment is not a totally perfect sunlight substitute. The most powerful LED light bulbs will not be able to recreate the energy of the sun. That’s exactly why an ideal option to get a truly full-scale spectrum of natural lights is placing your plants outdoors.

5. Costs less

This point might be pretty obvious. All you need to grow outdoor weed are some high-quality seeds and a place to plant them. No doubt, the quality of your herbs will be improved when you invest in them, acquiring fine soil, using only organic fertilizers and of course – do not forget to water your grass!

What is needed for growing cannabis outdoors

1. Get some seeds

In case if you have a direct access to a seed bank, this won’t make a big problem for you. But if ordering from a seed bank overseas, be ready to wait for about half a month for some nice seeds to arrive.

2. Acquire the needed gear

You’ll need to purchase some necessary equipment for starting your cannabis garden. Depending on how fast you’ll manage to purchase all the needed equipment and how long you will be setting all up, everything can be ready the same day or in a few days.

3. Do not forget the fertilizer

Marijuana seeds and plants do require some specific “food” in order to go up. Try looking for the nutrient options designed specifically for cultivating cannabis. However those can often be pretty expensive and might damage soil bacteria as they mostly contain synthetic minerals and intended for indoor growing only.

4. Choose a perfect soil

Clay soil drains slowly and does not keep oxygen well, so it will need to be significantly amended.

Sandy soils are easy enough to work with, as they drain very well and warm really fast, but do not expect those to hold nutrients for long, especially in rainy climate.

Silt soils can make an ideal growing medium. They are simple to work with, warm quickly, hold moisture for a long time and contain lots of nutrients.

In any case, the real length of the vegetative stage is fully a matter of personal preferences.

    On Vancouver island in month four and barely showing bud formation. It has been hot here (overly) for weed. Used shade on the potted plants and the in ground plants took the heat better, I guess. My rear is they are late to giddy up bidding. I am at PH7.0 used N P K and now on to 0 10 10 so I think I am on track. Any on else fearful plants are turning to bud quick enough running out if grow time and light reduction will help fill em out so hopefully I still have time for a good outcome.

    First year growers. Just wondered if I could send some pics to you. Just want your opinion on whether my plants look Ok. I have 4 plants and two different types. One plant has seeded which is fine – I’ll use it for seeds and cooking. We think it was pollinated by the bees. Can it harm my other plants.
