I use an Ebb and Flow (fill and drain) system. 2 of them to be exact...check out either my Maine grown jounal post...just getting going with this grow...or my MOB a look back grow which I'm just finishing up :)
Yup, if you are using the right type of system I do believe you can. Tray systems I think will work with soil, but the type I run will not. Check out this link...tray type is second...I use the 3rd option (to me option 1 and 3 are basically the same...hence why I previously said 2 types not 3).
