For my first grow, i'm just learning with a simple DWC system, I just have a few questions before I go ahead and start her up.

When I was reading, there was a few things I couldnt find in plane english.

Im using rockwool in clay rocks, suspended over my reservoir, my questions are: How far below the rockwool do I have my nurtient soloution?

Mines not self draining.... so how often should I completely flush/change/clear out the nutrient soloution?

Sorry if these are stupids questions, I really have done my best to read it up, I am just a little dense, perhaps :smokin:

Oh lastly, what would be the best way to cleanse my rockrool of PH before I use it.

Thanks!
