Are you deciding what schedule you should be following regarding the growing and harvesting of your cannabis crop? First, here are some important things that you should consider:

The Cannabis’ Growing Season Will Change with Where you are in the World

When does flowering start outdoors? The time of harvest is in September or October if you are growing cannabis in the Northern Hemisphere. However, the seasons will be reversed for those located in the Southern Hemisphere. As an American grower, you may look forward to planting seeds in March. On the other hand, your Australian counterparts will be getting ready to harvest their crop at that time! For cultivators who live near the equator, you can harvest cannabis all year round.

The Cannabis’ Growing Season Will Vary Indoors and Outdoors

Besides the geographic location, cannabis growers should also know that their indoor grow calendar will be different from an outdoor one. For instance, by exposing your cannabis plants to 12 hours of continuous darkness for a couple of weeks, you can bring on their flowering stage forcefully. That is, of course, only possible if you are growing them indoors. For outdoor growers, your calendar will be tied to the area’s natural climate.

The Cannabis’ Growing Season Will Change with Where you are in the US

Your location will dictate when your plants will enter the flowering stage when you grow them outside. For instance, any marijuana strain entering theirs in Colorado at the beginning of July won’t flower until at least a month later if taken to Amsterdam.

The Cannabis’ Growing Season will be Different for Different Strains

Besides the environmental factors, such as rainfall, temperature, etc., and the geographic ones, cannabis growers also need to consider strain genetics. You fare better in your native clime than you would in an alien environment. Cannabis varieties do the same and are best suited to their local climate.

Generally, indicas will not gain much height before they begin to flower. The equatorial sativas, however, show late season for outdoor grow. Their longer flowering time makes them ill-suited to locations extremely north or south. Wondering what the average height of a cannabis plant has to do with harvesting them? Well, indicas are stouter and bushier. They are also harvested earlier because their inflorescence can become moldy.

The Cannabis’ Growing Season May Not Mean Much to you if you Grow your Crop in a Greenhouse

Finally, as a modern cannabis grower, you may not be constrained much by the seasons. You could cultivate your cannabis crop in a greenhouse. In a controlled environment, like a greenhouse, you can simulate longer nights by periodically blocking out the light within and get three-four harvests per year out of your crops.

Within your greenhouse, you wouldn’t have to worry about other factors affecting plant growth, such as water availability. Electricity and water pumps make hydroponic indoor growth possible all year-round. Therefore, you can keep producing flowering cannabis plants and harvesting them.

Does that last bit sound interesting to you? Are you considering starting a grow op? Start with the right supplies from a supplier dedicated to the cannabis industry.
