My DWC is exceptionall simple.
5gal bucket, net pot, and a couple of air-stones(lots of air).
I've thinned, and lollpoped...this time I only removed the leaves that were dead/dying, biggest yeild to date.
This is just me. For a noob DWC grower I recommend, Advanced Nutrients Ph Perfect, 3-part, with the Hobbyisy Grow bundle.
It's easy to use and almost idiot proof at 80% recommended strength.
I've used AN for about a year, now I've decided to give DNF a try.
Have fun, and good luck
