Watering Details

So below is a pic of what I have going on at this point, 11 plants under an led bulb, so today is the first day of watering now I know I do not add much as to not drown them but approximately how much water should I add to each cup, and what should the ph level ideally be at I was told 5.8-6.2 but I just wanna get some confirmation on these numbers, thanks!

Depends on environment age etc. as a rule of thumb, for me anyway, I like to use 10% of the media volume in water. You want to keep the soil moist but not soaked. Doesn’t look like there is much soil in those cups so keeping it consistent may be kind of tough

for sure, yea they are only gonna be in those cups under that light until about Wednesday then im going to look into getting them in some 10 gallon pots outside
