Sorry. Looking back at what I posted, I thought it could be seen as rude. I would (and do) incorporate permaculture design aspects into my bio intensive backyard garden system. Permaculture is about observing the world around you and design your space to take care of the earth, to take care of the people, and to share the surplus. So if you look at the system you want to create, plan accordingly, and then incorporate intensive practices into the system so that they are benefiting the system as a whole, you'd have both a permaculture design and a bio intensive one.
Observation is key and as time passes you will notice what works and what doesn't work as well. You then adjust accordingly. I have a rain garden with natives in my plotted area. It soaks the ground around it. Over the years, I have retaken to planting zucchini, tomatoes, ect in the beds that get the heaviest drink because they do not like their leaves getting wet. I have found that my powdery mildew dropped dramatically after I did this.
I hope this helped.
