Thanks, you've put my mind at ease some. I had already started my 2nd batch two weeks ago, just assuming I could re-use the soil. And started getting paranoid I would run into some big problems later. I did let the soil dry out for 2 weeks and trying to change the soil at this point might cause more harm. So I'll hope for the best.I've re-used my soil quite often with no adverse effects that I've seen. The only thing that would stop me from re-using it would be if I had a serious bug problem or mold/mildew/disease on the plants. Then I would use new soil.
well i know that the corn crops have to rotate crops because plants strip nutrients out of the soil and have to rotate it to replenish it.
Haha I can't help but think we're comparing apples to oranges. I have an outdoor garden too, and my wife and I rotate our crops outside. But the question was for re-using soil in an indoor grow. To each his own, but I've reused a lot of my soil indoors for my grows, and like I said I've had no ill effects that I've been able to see.This is why you don't reuse it right away.... the best use is in a compost pile outside and then use it in an outdoor garden.
Good article. I would do that if I was bringing soil indoors from outside for use in my grow room. My soil is always isolated to my grow cab or in 5 gallon buckets with the lids shut. If I had a bug problem or disease I would definitely throw the soil out.
Thanks for the link, I was curious about sterilizing the soil. I had a problem with gnats last time that were a PIA to get rid off, so it will come in handy for next time.
