Do Your Research
The next thing you want to do is research more about marijuana farming. It would be best to go in after getting some basics on what marijuana farming is all about.
There are tons of information available online that can be helpful to you as a novice in cannabis farming.
Doing so will at least give you insight into what you are in for as well as help you identify what it is that you need to have for a start.
The good thing is that as a novice, you can start small as you aim to increase your yield with time.
Getting the basics right is what matters the most so as to avoid disappointments while at it already.
However, note that cannabis farming is always a learning process. There are things you will not learn from the online materials but will get to learn while doing the farming.
