I have not used the 707 over before, but I have re-used the reg roots, I just added a lil alpaca manure, EWC, kelp meal, and rock dusts. Not too hard. I then fed the plants with teas, three times, every other week during flowering, I used guano, molasses and kelp for my teas.Just wondering if any body has used the roots organics bags for a full grow and then reused them? If so what did you notice or have to add?
