Greenhouse structures range from inexpensive polyvinyl chloride (PVC) tubes, often called “hoop houses,” to highly engineered, fully automated, and purpose-built steel greenhouses. Due to their efficiency, greenhouses are quickly becoming the preferred growing method for many large-scale cultivators.

Avoid spraying synthetic insecticides on your cannabis plants as further research is needed to determine the health effects of smoking plants treated with synthetic chemicals. Organic pesticide and insecticide solutions can be effective if used properly. If you can avoid it, it is always best to not spray anything on your plants while they are flowering.

Avoid clay pots as they can be costly, heavy, and retain heat that could dry out the plant’s soil and roots. Fabric pots are the least expensive and most effective solution, as they allow for ample drainage and plenty of oxygen to get to the roots. Plastic containers are also light and inexpensive but tend to retain more heat than fabric pots. Flowering plants need a container that is at least 5 gallons (18.9 liters) to prevent them from outgrowing their containers and becoming rootbound.

Greenhouses also offer growers the ability to harvest more than once per year, if they are equipped with a light deprivation system. These systems allow growers to control the hours of sunlight their plants receive, much like turning lights on and off in an indoor garden, by covering the greenhouse with a black tarp that deprives the plants of sunlight.

In the Northern Hemisphere, cannabis can be planted in early to mid-spring and harvested in mid-fall, depending on the cultivar. In the Southern Hemisphere, the growing season will be reversed with planting in early to mid-fall and harvesting in the middle of spring.

Deciding whether to start with seeds or clones will change the timing and manner by which your plants are introduced to the outdoors.

During the drying process, the water content should be reduced from 75% to approximately 10%, taking about 10 to 15 days. The method to follow is really simple, we cut the branches, peel the leaves and then hang the peeled branches upside down, avoiding that they touch each other and give them direct light. We must also consider that they are in an airy and damp-free environment.

These are some necessary pest prevention recommendations, but what other factors do we need to consider during the plant’s growth and development phase? Fertilizers are of vital importance for the quality of our harvest. While our plant develops we must fertilize it so it develops properly. In addition, it is vitally important to control the Ph of the irrigation water. High or low pH levels have a direct influence on the correct development of the plant and, therefore, we must use a pH meter to control it.

In the following article we show you the steps to follow and the techniques to use to obtain a good outdoor marijuana harvest. Obviously, we can just water the plant and observe how it follows its natural process, but that will not guarantee a high-quality harvest. Therefore, if we want a good result, we must follow certain guidelines that we will summarize below.

Drying and curing of outdoor plants

The first step, but no less important, is the germination. We have already dealt with this subject in other articles of our blog, so if you want more information you only must consult them.

Remember that autoflowering plants are recommended to be sown directly in the definitive culture medium because of their fast cycle.

First of all, Neem oil will protect our crop from very typical insects such as the whitefly or aphid. Secondly, propolix, which will protect our plants from fungi such as powdery mildew and brotitis. We will add this product every 20 days and we will stop using it 3 days before the harvest to avoid residues in the buds that we will smoke. Finally, the Bacilus thuringiensis, which will serve to protect our precious plants from worms. This is very important, because if we don’t remedy this plague, it will end up eating our buds from the inside to the outside and ruining our entire crop. To avoid surprises we will start spraying at the beginning of June and repeat every 20 days, not using it 30 days before harvest.

Growing phase in outdoor plants

Once the growth phase is over, approximately on June 24th, the day will begin to shrink, shortening the photoperiod of light, so, our plant will begin the flowering phase. Many growers recommend a change of flowerpot just before beginning to flower, so that the plant can face the last effort and subsequent flowering. The change of pot depends on the flowerpot that you have previously selected, maybe in the previous transplant you have already put it in its final pot.

The last few weeks, once we have done the root washing, we should let the soil dry and keep the plant only water-based. Finally, a day or two before harvesting, it is better not to water the soil, so when you cut the buds, you will avoid the moisture excess inside them. If we don’t do this, buds will have water inside and we run the risk of rotting them or suffer the fungus attack.
