It’s fine lol just have plenty of airflow above and under the canopy

Might limit training possibilities but should be fine if you don’t try to spread the canopy as far as possible on each plant.

Mine is stuffed full as well

I have 3 in a 4×4 in autopots. I really like the system. As zoomycat mentioned, it makes training a bit more difficult if you are like me and love to train my plants. I didn’t expect them to bush out so much. The little fella in the back is a different strain and doesn’t like the LST like the others. Make sure you have lots of air flow above and below. Perhaps put up netting to SCROG and have a massive canopy that is supported.

best of luck my friend. Keep us updated.
