The framed PDC certificate on my wall says otherwise, but I am still pretty much a novice when it comes to all things Permaculture. On the other hand, that's the goal of these forums, isn't it? To never stop learning.
I don't have a journal. Of any sort. Yet. However, I am seriously considering purchasing a Dot-grid notebook that can be solely used to record the goings-on in my balcony garden as soon as the new growing season kicks off in August (here in the Southern Hemisphere). The dots make it versatile, for both sketching and writing.
And suddenly I can see how the notebook can also help me with the "observation" part of Permaculture. Maybe I shall buy that notebook sooner!
