No one germinates in hydroton, your either going to buy Rockwool, Grow plugs, or Rapid rooters. then your going to germinate either in a paper towel that is kept dark damp and warm, or you can throw them in a cup of water. Once the tap root sticks out your going to place it in one of the afore mentioned mediums wait for it to root and then your going to stick it in your "clay rocks".
socialistpete Reviewed by socialistpete on . Germinating seed Question. I would like to germinate some seed for an upcoming grow. My plan to is grow in clay rock (hydroton) What would be a good medium to germinate seeds in - that I can also use in / transplant into the hydroton when it's time ? Doesn't make sense to germinate in soil &/or rockwoll then move them into hydroton. I also think it would be difficult to germinate in clay rock. Rating: 5
