One way to make a log for your grow is to find the right section for your thread, if its indoor gardening or maybe a section for grow logs I can't recall. But just make a new thread titled 600w White Widow or whatever you want to name your grow thread. Then just post the info about your grow in that thread. List things such as your strain, nutes, lighting, post some of the info from your logs at home into the thread to give others a better idea about your grow so we can follow along. Whenever you change or do something different, make a post in your grow thread. For my grow log I try and upload some pic's, video, or comment at least once a week or more. You could also keep track of any problems with your grow and what you did to remedy the issue. I'm sure you already know and get the idea of keeping logs, but I;m just saying that this the forum is a great tool and place to upload and keep track of things. Once you are more active on the forums, and become a well known member you can then open a grow journal. I'm not so well informed about how to properly utilize the grow journal features so I prefer to just keep updating things in the grow thread I have going that I'm calling a grow log. If you look at my avatar you can see a little box with a B in the upper left corner. You can click that and it will go to my grow journal. Like I said I prefer my grow thread/log though so I provided a link to that thread from my grow journal.
