Hi just wondering i am starting a top fed DWC how long do I keep the top fed going for?

I am not a DWC guy so I can't answer your question, but I would like to welcome you to the site. For a really good read on DWC I recommend the following.

Howdy Breaking my Cherry and welcome,
I am on my fifth DWC grow and I run the top feed (actually at the bottom of the rockwool cube) continuously during the grow. The flow encourages the roots to grow down into the reservoir and helps to circulate the water and nutrients. The only time that I turn off the pump is if it gets clogged with roots. The most important things to do, from my experience, is keep ALL light out of the reservoir, keep the water very well aerated, and keep the water temperature between 64 and 70 deg. F.. I also recommend using an antimicrobial like Florashield, Hydroguard, or hydrogen peroxide to help keep algae and fungus under control.
good luck with your endeavor.

I used to top feed, but it's completely unecessary.
1. Pump and pipes/tubing clog often
2. Pump heats up the water
3. Extra costs (purchasing and operating costs) for something that's just not needed

Just bring the water level high enough to submerge the netpot in water and have ample aeration. That's all you need and the roots will grow straight down into the reservoir. Lower the water level once the roots descend into the res.

Clones or seeds?

This is new information to me. Can you perhaps start a new thread and show some pics of how you do it, or is what you wrote here about all the difference that there is?
