You will love how forgiving growing organically is. If you have landscaping, use the leftovers around the property, they'll love you for it. As a matter of fact, when we moved into this house the ground was mostly weeds and there was no landscaping. Being a new construction most of the top "soil" (we don't exactly have soil here, it's clay and rock) had been removed. No worms, not much life, only weeds grew. Then I hit one slope with as much leftover tea with mycorrhizae as I could, and within just a few weeks I was finding red wigglers all OVER the place and the clay had loosened up.
Also, the flavor of the smoke is very good and difficult to screw up using organics.

I like the idea of doing a single bed, but if you do go that route I highly recommend monocropping. It really saves a lot of headaches, especially if you're working the exact same phenos.
