hydro / rockwool question

4 pot wilma - seedlings going under the hps tonight, not yet watered using drippers (im using 1inch rockwool inside 5 inch, with clay pepples) - does the dripper go directly next to the root?

Imo dont put them to close to the hps and yet not to far away , you'll have to adjust them as they grow so they dont stretch and keep tight node space. Put the dripper close but it doesnt matter cuz you do not want to use the dripper just yet , maybe when they are a month old but not yet. Just my 2 cents Good Luck!

Happy Growing!
