I love DWC! I use Hydroguard to prevent root problems, I highly recommend it.
DWC is a bit time intensive. Each day after checking/adjusting pH, I prepare water to add back in. It’s important to keep the water level at 1/2” to an inch below the netpot, and not let it dip down below that level. It’s a lot of work but I think it’s worth it:View attachment 992630
Oh bloody hell, I read that you only need to change water every 2 weeks and not to top up.
Was hoping for an easier way. Could go on holiday and leave them etc.
Didn't know needed to do it every day.
Well I've got roots coming out bottom of the rock wool and have put an inch of clay peddles on pot.
Soon as see roots coming out net pot I was going to put into the DWC bubbler and have water just below net pot
