I have, GK posted a Grow Room that has been re-using the same medium for 5 years. Wann bet on how long it takes for some one to tell me I'm wrong about this?? VV
not if you flushed properly at the end of your grow....then i would even flush the soil a bit more before removing the rootball(which is what i did) and have at it. the soil in a few of my containers is going on three grows now.no problems at all.
he said he chopped down his males, so i figured that they were still getting vegg nutes and didnt get flushed because there would be no point of flushing males when your going to chop them down.... just my humble opinion.
