I think four would be where you want to be mate. 5 you may end up with some crowding. You know empty pots make it seem that there’s lots of space but you have to think that the canopy can easily take up double the pot circumference. Take a look at some of my latest grows. I had three in there and I felt pretty crowded. Granted those a photos but still you have to take into account the canopy space. But with autos if you keep them small enough you may be able to get away with doing 5. I honestly think four is enough though. Merry Christmas brother 🤙
