Step 1: Source Your Supplies

The government has put in place strict cannabis regulations to ensure that weed cultivation for commercial purposes has the right concentration of compounds like THC. Therefore, you should source your planting material from reputable suppliers. Currently, seed propagation is the most common method of weed propagation. Ensure that the seeds are viable and free from foreign material.

You should ensure that the supplier is licensed to supply weed seeds. The planting material should also be viable. The date of packaging helps you to know the viability of the seeds. The can check the expiry period of the material.

Apart from planting material, there are other essential tools the farmer should have. Shears, hygrometer, thermometer, pH meters, and microscope are all essential. Shears are used to trim and prune your crop. They can also be used to prepare cuttings for planting. A hygrometer comes in handy in monitoring the humidity of the planting space. A thermometer helps to know the temperature to adjust lighting and ventilation accordingly. A microscope helps in the detection of your crop sex and identification of bugs in the field.

Step 2: Preparation of the Tent/Greenhouse

Although weed has few pests, diseases or weeds that affect it, it is essential to have a clean field for high productivity. After tilling the planting space, you should know the spacing you will use for healthy plants. The spacing should be at least 1ft from one plant to another.

You can plant weed in grow tents, greenhouse, or grow rooms. The most crucial aspect of cannabis cultivation is lighting. You should also ensure that space is well ventilated to allow for a free flow of air.

You can supplement natural light with artificial grow lights. The most common lighting systems include high-intensity discharge (HID), fluorescent grow, LED grow, and induction grow lights. HID grow lights are the most common because of their ability to discharge enough light, efficiency, and value for money.

Step 3: Select Weed Growing Medium

You can plant weed on soil, hydroponics or coco. Each medium determines the nutrition requirements of your crop. You should test the concentration of essential nutrients in the soil before planting the seeds. For first timer weed farmers, using soil as the medium is advisable because it does not require a lot of technical skills. You can use pre-fertilized soil which is also referred to as super soil. It contains all the necessary nutrients for the growth of cannabis from planting to harvesting.

Step 4: Plant Your Material

Although there are other propagation methods like cuttings and tissue culture, seeds are the most common method. You can soak the seeds for 1-2 days to break seed dormancy. Feminized seeds are the best for cannabis. In case you are using clones, ensure they are from healthy mothers.

You should plant the material in pots for easy care and maintenance practices. You should make holes that are between 0.5-1cm in depth. You can use a dibber or a pencil to make the holes. After that, put one seed or cutting in the hole and cover it with the soil. Depending on the condition of your soil, you can water the soil to facilitate germination.

Step 5: Taking Care of Weed Seedlings

Cannabis requires primary nutrients (nitrogen, phosphorus, and potassium). The other nutrients requirements include calcium, iron, magnesium, and copper (micronutrients). Micronutrients are required in smaller quantities compared to macronutrients.

Cannabis has low water requirements. But in case of extreme conditions, it is important to irrigate the plants for fast growth. You should check the nutrient concentration of your medium every 2 weeks to correct any deficiency. You should ensure the water you are using is free from excess chlorine which can destroy essential microbes in the soil. The water should also not lead to the build-up of excess salts in the roots, hindering mineral uptake.

You should also regulate temperatures, lighting, humidity, and ventilation. Daily check on these factors to adjust accordingly is advisable.

Step 6: cannabis Harvesting

Marijuana plant takes around 3 months to grow. The harvesting period varies depending on the purpose of the crop.

Step 7: Drying and Curing

After harvesting, you should hang the buds upside down for slow drying. The harvest should not be exposed to excess light as well. Keep checking for molds or excess drying to avoid the growth of molds.

The curing process starts once the buds are dry. You should put the buds in a mason jar for at least 2 weeks to make them smooth and improve the smell. You should open the jar at least once each day to allow the circulation of fresh air.
