couple things to do to make your 'used' soil good again-
-A bit of lime to get the pH back in shape
-If I were you I'd water it with a product called Soil Syrup or anything else that has humic acid in it. Conditions the soil and buffers the pH.
-If you have a compost heap with leaf humus in it, mix your soil with that.
-Add some composted cow maure and kelp compost if you can find it to refresh the nutes and stimulate beneficials
stinkyattic Reviewed by stinkyattic on . Potting soil question I'm a indoor grower .... next season in NE Ohio I plan to plant some of my clones outside. I have lots of used potting soil I've dumped in a container that I use in my yard. Can I use that soil to plant my clones? It's been sitting for over a year ... (soil near the bottom) .... it will be sitting over the winter. What can I do with it to prepare it for next spring plant? Also how should I prepare the clones for going outside without shocking them? They are use to indoors and indoor Rating: 5
