Why would you want to do that? Don't you know that soil has parasites, bad Ph, and clays that harm your plants and it's root systems. Sure you can grow in soil, but your plants will never reach it's maximum potential. Rockwool is better than soil, but hydro machines are even better! I grow in rockwool and I also use hydro systems. I started off growing in soil, then went to Rockwool, then hydro system. Out of the three hydro is the best, then rockwool, then soil.
Just as a note, I've been growing for better than 20 years and have the best success with hydro machines. Which by the way are very easy to make at home with a few items from places like home depot or Lowe's.
