I use my own mix from the back yard that works wonders but i was thinking about the bags of soil you can buy. They say on some of them that they feed up to 9 months without extrx food,do they? Cant last that long with watering
no they dont. at least not for what we gro. they would be good for vegn a couple of weeks to support a new plant and then you would have to start adding nutes as the plant matures.
