  2. Depends on how fast your growing medium drains. Most people start with 4 to 6 flood cycles per day and increase as needed from what I've seen. I'm doing 6 flood cycles during the light hours using hydroton.
     
  3. that seems like alot 24 cycles a day
    plants roots need oxygen in elevated levels
     
  4. Thanks for the info guys... Newbies are drooping showing signs of over watering... I have backed it down to 6 a day, I flood and drain quickly... So 15mins ON every 4 hrs seems better.
     
  5. It depends on the medium and how fast your tray fills. I use rockwool and flood twice a day for 15 minutes and that works out great. Depending on the weather, I might even skip a flooding if the rockwool seems waterlogged.
