Dan when i go coco i'll start with the ROOTS, I have read several threads and i think it will be a home run for the V+B supporters, from the pictures i have looked at here and elsewhere on other sites has some really nice full plants with just water for the first 3 weeks, it has been suggested to start feeding somewhere between weeks three and four if you want a longer veg, most of the people use Maxi Grow with great success for those extra weeks in veg if ya need them, hope that info is useful to you Dan. Ive read about 120 threads and those were my findings.
