1. It was mentioned above that cannabis plants are adaptable for climate, but extreme weather conditions such as winds, rains, or high (low) temperatures significantly affect the process of growing. To this end, it would be better if you have experience of growing plants outside, so you know your climate and length of the day.
2. Picking a place, have regard to the fact that it shouldn't be grown right near the street, maybe you would prefer to choose a sun-lighted balcony or rooftop.
3. Perhaps you should do some research on cultivars of cannabis, since they have different requirements, and find something that suits your climate the most.
4. Examine your soil and the components of it, if you are going to plant cannabis right in the ground. There is a soil testing service, that can help you with that. If your soil is sandy or heavy-clay, you will probably need to add compost or other decomposed organic matter. The best option would be silty soil, as it is easy to work with and contains a lot of important nutrients.
5. Additionally, knowledge of your soil will help you understand the amount and type of fertilizer that should be used.
6. If your ground is not the option, you should pick up some containers. In that case, you will use the nutrients and fertilizers designed especially for indoor-growing. But you do have a great advantage: you can move the containers, subject to the position of the sun during the day or in order to hide it from adverse weather conditions.
7. During the hot months, you should provide cannabis with water, while rain will do this job at other times. Sometimes your plants require a huge amount of water per day. But make sure that they will not be overwatered. To this end you may improve drainage around your garden.
8. Last but probably the most important step is protection. It again depends on your climate, so consider the necessity of setting up a greenhouse, windbreak, or plastic sheeting for the purposes of protection. Also, keep your plants healthy and check them regularly for the presence of different insects.
