I have a northern lights seedling that is about a week old. The cotyledons are still there, the first true leaves are about half an inch long, and the second set of true leaves are starting to appear but are just tiny little nubs. How often should I be watering at this point? I just have it in a little red party cup with holes in the bottom for drainage. After a day it seems to be very dry even a little under the surface, so I have been watering it daily. Just today I noticed that the first true leaves are starting to look a little droopy so I'm wondering if once a day is over watering it. Any thoughts or suggestions?
Um well as much as you want. Rockwoll is used in hydroponics. You can't over water it because it doesn't rot.
