Time to flip?

With such a small amount of vertical space, you may want to flip sooner rather than later. You will gain a good bit of height during early flower and you have to make sure you have enough space between the light and canopy. The last thing you want is to have them grow too close to the light and not have enough space to back that light off, light stress no good. The way they look now, you would get a pretty decent yield if you flipped em in the next day or so. Happy growing.

Hey, Expect your plants to double, roughly. I would fill every square before flipping. Cheers,
