Choosing the right seeds and pots
First, you will have to choose the type of marijuana seeds you want to grow, whether hemp seeds or CBD seeds , outdoor marijuana seeds , feminized or automatic seeds, choosing those perfect genetics for growing marijuana outdoors.
Once you have the seed, you can germinate it using the napkin method. The next step is to choose the appropriate substrate for the chosen growing area, since the same soil is not needed for a plant that is in a very humid place as in a very dry one.
You should also have a few pots for the plants. Even if it is planted in the field in the ground, it will be necessary to grow the seeds a little before transferring them to their definitive medium, to ensure the survival of the plant in a hostile environment. Specifically, two sizes of pots are needed, such as:
- One of 7x7x9 cm to place the seeds once they have germinated, when the root has begun to grow. It is placed at a shallow depth.
- A pot for its growth .
The first days of life
After about 10 days, the plant will have stretched almost to the point of bending. Now it will have to be placed in a 3.5 L pot. More or less the trunk, which usually comes out somewhat weak, will have to be buried in about two thirds, which would be about 6 out of 10 cm of the trunk. This prevents it from bending, and it will also grow extra roots in that part that you buried, causing more vigorous growth. You have to water around the edges until the plant begins to absorb more water , since if the trunk gets wet it could end up rotting.
These plants will have to be kept in a place where they receive direct sunlight , if possible, sheltered from the wind and cold, and you may even bring them indoors at night on the coldest nights or on very windy days. When it lifts a hand’s breadth off the ground , about a month old, you can take it outside, as it will have resistance to different attacks.
Choose quality preventative products
It is essential to have three preventive products apart from fertilizers when growing plants outdoors, which are:
- Neem is used to repel insects such as whiteflies and aphids . You have to use it as soon as spring begins; The first spray that can be given to your plants will be this natural product. It comes from a poisonous plant , so if insects smell like the Neem plant, they will prefer any other plant. Products like ProNeem can be very useful.
- Fungi Boom , from Boom Nutrients, will prevent the plant from being infected by the typical fungi that attack cannabis plants (botrytis, powdery mildew, mildew…). By applying this fungicide, the structure of the plant will be much thicker, since the product contains silicon. In this way, unwanted insects are also prevented from approaching. It is essential to prevent the appearance of fungi in cannabis cultivation, especially in the first and last weeks of development, which is when plants are most exposed to infection.
- The Soil Care Boom will kill the worms and larvae , preventing them from destroying the harvest. Sometimes it is very difficult to detect them, since they camouflage themselves very well among the buds. It is always better to be safe than sorry , so you should apply the first spray for the first time at the beginning of June, and repeat every 20 days until there is a month left before cutting.
To spray the plants, it is necessary that they be of a certain size, since a plant that still has a very thin trunk will bend too much and will not support the weight of the water: you need a strong plant.
Fertilizer and pH tables for growing outdoors
Every day, the plants will continue to grow. Although at first water and sun will be enough, little by little it should be fertilized so that it can develop well and control the pH of the irrigation water. If the pH of the water is not measured, when there are deficiencies it will not be known if it is because something is missing or because it does not absorb the nutrients provided to it well, which is what happens when the pH levels are very high or very low.
The pH in marijuana cultivation , during the growth season or phase, should be 5.5 to 5.8, with fertilizers included. There are a large number of marijuana fertilizers available and the plants will appreciate care with organic fertilizers, if you want to exploit the plant to the fullest.
During this period the plant will need fertilizers rich in nitrogen, which is what it needs the most. This can be given in the form of worm humus on the ground and complemented with some other biological fertilizer such as Bio Vega from Canna.
Necessary transplants
Once the plants stop growing then they will need a transplant and a larger pot will be needed , more or less double the size of the one in place at that time. We will wait until it stops growing before it can be transplanted again. Otherwise it won’t grow again.
When summer approaches and the day begins to get shorter, the plants will begin to flower. Therefore, when July or so enters, it is the ideal time to transplant to the final pot.
How to grow marijuana outdoors
When the last transplant is done, the soil can be enriched with guano , such as Guano Boom , whether in a large pot or in a hole in the field. To do this, fill the pot or hole with a good substrate that adapts to our terrain, and mix it with guano, more or less a tablespoon for every 7L of soil.
Bat guano is a slowly absorbed nutrient , with high levels of phosphorus and potassium. A month after putting it in that pot or in the hole with guano, a groove must be made around the trunk to repeat the dose, and the groove must be covered again. When you water it, it will penetrate downwards and there will practically be enough for the entire flowering period. With the help of Blooming Boom , for example, or a complete flowering fertilizer.
With this, you reach the end of an outdoor crop with a quality final product, in a relatively easy way. When you have 15 days left to cut it, you must wash the soil with plenty of water to remove any excess nutrients it has , and so that it is as clean as possible of products when it is cut.
Once the washing is done, you will have to wait for the soil to dry well and then keep it only with water until the day of harvest, when the soil must be dry, to prevent the plant from having a lot of water inside and from running. the risk of the buds rotting inside or any problem of that type. You just have to dry the marijuana, cure it, and everything will be ready to enjoy it. Finally, it is also recommended to use bud peelers if you have a large crop
