How to set up your outdoor marijuana grow
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.
Start off with fertilizers that are inexpensive and readily available. Some release nutrients quickly and are easily used by the plant, while others take weeks or months to release usable nutrients. If done correctly, you can mix in a few of these products with your soil amendments to provide enough nutrients for the entire life of your plants. Most of these items can be purchased cheaply at your local nursery.
You may need to put all of your plants in containers if you don’t have great soil. Also, if you’re unable to perform the heavy labor needed to dig holes and amend soil, containers may be the only way for you to grow your own cannabis outdoors.
Many growers will start plants in a one-gallon pot and then transplant up to a bigger pot as plants get bigger. A lot of growers will transplant once, from a one-gallon to a five-gallon pot, and harvest from there. If your plants get bigger, they may need a seven- or ten-gallon pot.
When starting with clones or seedlings, you’ll want to check your plants every day because they’re delicate and sensitive to environmental conditions. You may need to adjust temperature and humidity levels in your indoor grow space at first to hit the sweet spot for your plants.
Before watering, check the pH of your water and add pH Up or Down if needed.
What to look for in a pot
Proper air circulation will help maintain temperature and humidity, and also bring down odor. Ideally, air needs to move through a garden every few minutes, and you should create a vent to the outside. Oscillating fans, and intake and exhaust fans can move air through your garden quickly, taking odors out with them.
Below is a list of things to consider and equipment you will need to purchase to get started growing marijuana indoors.
These come in different shapes and sizes and are a great way to get rid of odor in an indoor weed grow. Also known as “carbon scrubbers” for their ability to get contaminants out of the air, these employ activated and highly ionized carbon to attract particulates responsible for carrying odor, such as dust, hair, mold spores, and volatile organic compounds, and traps them in a filter.
You’ll need to ensure that temperatures remain within a comfortable range for your plants, between 70-85°F when lights are on and between 58-70°F when off. Some varieties of cannabis—generally indicas—prefer the colder side of the range, while others—typically sativas—are more tolerant of high temperatures.
If you want a tall plant, choose the tallest male you have at your disposal. Maybe you want a generation of productive males? If so, choose the plant with the most pollen sacs.
Likewise, cross a regular male with a high-THC or high-CBD strain to boost cannabinoid levels.
However, space isn’t usually an issue outdoors. Growers can cultivate tall and productive plants that provide bigger yields.
STEP 1: CHOOSE A MALE AND COLLECT POLLEN
It’s a good idea to weigh your pots before you water them. If possible, place them on a scale. Every time you water them, the soil will retain water, and each pot will become significantly heavier.
Regular cannabis seeds are free from human tampering. Every time you germinate them, you’re taking a gamble. There’s an even chance that they’ll grow up to be flowering females or pollen-producing males.
Feminized seeds are ideal for growers looking exclusively for buds, but regular seeds have their own list of benefits. Chiefly, they’re paramount in the creation of novel strains. Regular seeds also tend to produce more vigorous plants. These specimens are hardier, can tolerate stress well, and produce cuttings that exhibit explosive growth and awesome yields.
Outdoor plants are also more susceptible to pests and fungal diseases.
