<span class="link_user">@siz3thr33</span>,Hi, best of luck growing without nutrients!!!!!!!!! I wouldn't you will run into all kinds of problems. you need at least some cal/mag which is cheap. Regards soil you can use common old garden soil but that can be a bit clay like and bog the roots down due to high water retention. I use canna terra at £10 which pots up 5 grows in 10litre pots:+1: Seedlings don't need nutrients to start with as the contain what they need for about ten days or so growth. It is then you would be starting with a low dose of what ever you choose to use.
