The three primary nutrients required for cultivating marijuana are nitrogen, phosphorus, and potassium.
Timing is key. A short vegetative phase can cause cannabis plants to flower early, while a long vegetative phase can prevent your plants from finishing their flowering cycle if the weather takes a turn for the worse. The Farmer’s Almanac is a reliable source for planning around the seasons and preparing your crop for success.
While cultivars may vary, here are some general rules that will be useful no matter which one you choose.
Most cultivars will begin to flower once they receive fewer than 15 hours of sunlight per day. The latitude of your garden has a direct impact on how many hours a day your plants receive light.
Organic sources of nutrients include alfalfa meal, bone meal, kelp meal, bat guano, fish emulsion, dolomite, and earthworm castings. Each contains different ratios of nutrients that can be used for different phases of the plants’ growth cycle.
Becoming intimately familiar with your local climate and seasons is one of the most important steps in producing high-quality outdoor marijuana. Before you grow, you’ll need to know the ideal temperature your plants require in order to thrive, the best site, optimal timing of planting and harvesting, and the season’s photoperiod — the amount and intensity of light available through the duration of the growing season.
For a small garden, hand-watering is the easiest, cheapest way to go. It also allows you to get familiar with each cultivar’s needs, and gives each plant the exact amount of water it requires. Irrigation systems can be convenient for a large number of plants or for times when you cannot be in your garden.
If you don’t have a suitable patch of earth to make a garden, containers can be placed on decks, patios, rooftops, and many other spots. If needed, you can move them around during the day to take advantage of the sun or to shield them from excessive heat or wind.
However, plants grown in pots, buckets, or barrels will likely be smaller than those planted in the ground because their root growth is restricted to the size of the container. In a broad sense, the size of the pot will determine the size of the plant, although it’s possible to grow large plants in small containers if proper techniques are used.
Cannabis plants require a large amount of nutrients over their life cycle, mainly in the form of nitrogen, phosphorus, and potassium. How much you need to add to your plants will depend on the composition of your soil.
Buying the right soil for an outdoor cannabis grow
Heavy clay soils drain slowly and don’t hold oxygen well, so they will need to be heavily amended. A few weeks before you plant, dig large holes where you’ll be placing your weed plants and mix in big amounts of compost, manure, worm castings, or other decomposed organic matter. This will provide aeration and drainage, as well as nutrients for the plants.
Don’t underestimate the therapeutic value of gardening. It’s relaxing to spend some time outside, roll up your sleeves, and get your hands dirty for a while. And there’s nothing better than smoking something you grew yourself.
In hot climates, sandy soil should be mulched to help with water retention and to keep roots from getting too hot.
How to set up your outdoor marijuana grow
Soil has three basic consistencies, in various ratios:
Here are some important considerations before starting an outdoor marijuana grow.
It isn’t easy to find the best location. Not only must it offer ideal growing conditions, but it must also be safe from discovery, even when planting legally. If you are adhering to the law, private property is best because you have full access and can control security. Otherwise, you have to risk public property, which increases the chances of discovery.
Tips for Choosing a Grow Site
For outdoor growers, it is best if you skip commercial fertilizers and focus on organic fertilizers. You should add it to the soil before planting and throughout the growth cycle. Natural options include:
Different Types of Soil
As we mentioned above, make sure the temperature of your location does not exceed 86 degrees. If your area regularly surpasses this temperature, then you will need to be careful where you cultivate your plants.
