Very 1st grow

I think it doesn't really matter how they are placed in the room provided they get the light they need , I always try to make it so that there is enough space for them to grow and not be touching each other but I mean you don't have too . I think your grow room is set up pretty good and the placement of your pots is pretty good . One thing I could suggest is maybe getting a Scrog this way when the go into flower at full force you can manage them a bit better if your running out of space . Everything seems to be in excellent order in this grow tho and I wouldn't change anything unless you feel like your plants are stressing but so far no signs of that ! I hope you find this helpful -Happy Growing!
