Hello, I'm a new member and would like to ask all you experts a few questions. This is my first grow and so far after 2 weeks the two WW that I am growing in dwc seem to be doing fine. My question is how long do I leave them in a veg phase with 18 hours light and 6 hours dark until they go into the bloom phase of 12-12. One more question, how deep should I run my water in the dwc when I change it.
