You can germinate your seeds in either a rockwool plug or even better, a rapid rooter. Once the seed is established in the plug/rooter you can then put it into the dwc system. The water level will need to be high enough to splash and hit the bottom of the netpot until you get roots that reach down for water.

I even sometimes top feed the basket with a dropper until the roots head south.


My very first DWC grow I actually germed in paper towel and CAREFULLY placed the seed directly in the hydroton. I dont recommend this but it is possible.


Some of the best advice I ever got from these forums were to start using rapid rooters...

Goodluck!
