I have not started nutrients yet, but when I do, I will water as usual. Any excess will go in to the red solo cup which they then can Wick from I have had no problems with the roots growing through the holes at the bottom of the clear cups that I make with a soldering iron. ( in case peeps want to know easy way to get holes…. And the same 2 cup system is how I do my solo cup grows.)….. see PIC where I used small plastic coffee containers for reservoirs, plus they make good little stands as you can put rocks in the bottom of them to help weigh them down so they don’t blow over…. having these for seedlings and for solo cup grow offs are perfect as you don’t have to water so often as they can just wick up the excess.
There will be more pictures to follow and you can see, and if any roots do grow through those holes I am not worried about it. No probs in the past as when I transplant the roots come clean out..
