how often do i water

[jmy]

i built a 11 container garden and i am using lecca (round redish-brown rock) for a medium the question i have is how often do i water because i have excellent drainage and no fear of nutrient build up because i am not using rockwell cubes on this site it said every 20 to 30 minutes but my hydroponic salesman says start out at 3 times per day but that does not seem enough for i just switched from deep water where the roots were constantly submerged can anyone help i am very confused....jmycap

The advantage of Hydroponics is that you are forced feeding the plants if they like it or not. That's why with Hydroponics you can grow faster than with dirt. As long as you've got good and fast drainage then you can water every 30 minutes or so.
