coco doubles yields and quickens growth just like hydro except coco is more forgiving like soil.. i use coco. i water and feed just like soil, only more often.. also, coco allows more oxygen to your roots and is almost impossible to over water (unlike soil)… Once you grow in coco you will never look back or at any other method…. if you research others who use coco on this site, you will see that no one else will tell you any different. one caution i would warn you about is to make sure you buy top quality, salt free, coco. You can use all your organic foods and get organic quality results with hydro yields. i promise,,
