Hey RIU, I've been a long time follower but never had the time or the space to grow. I just recently bought a GH waterfarm and i am using it for 2 beans of an unknown but good strain. I know I will need to get another one to place one plant in each but for now 1 will have to do. my question is how do i place the seedlings in the hydroton and where do i place them, outside or inside the ring ? how deep do i place them (they are 5'' tall) and what is ppm. this is my first grow and i can't afford to mess it up. any positive feedback is appreciated .
