So I just started 12-12 lighting 3 days ago and have been watering once every 12 hours. Should I water right before the dark cycle or water twice only when the lights are on?
I generally water the plants by flushing an leave them until nearly completely dry, let the root search out and expand to find that moisture. Measure by the dry and wet heft of your pot or bucket and gauge it from that point when you'll need water. The plant is a living thing, it will let you know when it needs what it needs. Good luck chap, keep us posted
