Water Level in DWC?

[Gart79]

When using soil, itâ??s not good to water for 24 hours, as it will likely induce root rot, so I thought maybe, wet and damaged roots in DWC may be taken that way.

I donâ??t think I made that too clear. I meant, when using soil and transplanting, itâ??s not good to water for 24 hr after that, since damaged roots that are wet are prone to root rot.

With ref to water temp, the colder the water, the more o2 that can be dissolved, so it is definitely something I'll be keeping my wary eyes on! DWC isnâ??t the kind of system you can put your feet up with, thatâ??s for sure! Cheers for the input.
