You could also consider watering from the buttom. Have your pots standing in a tray in the grow room. Then pure the water in the tray. My current grow is being watered like that. It's the first time i do it, and i have to say i'm impressed compared to "normal" watering
Note how far up in the soil the roots are

System: ????
Water the plant with about 10-20% of the total pot volume
Lift the wet damp pot
Note how heavy the pot is
Return after 5-7 days
Elevate pot
Remembering from the previous weight
Decide to water Yes/No!
ps: Allow the water to rest overnite first
1: To get the water to room temp to avoid shocking the roots
2: Allow any chems in the water to evaporate off
