@@grzesiek, what do you mean by puffy leaves? I have a 4" filter/fan running at 1/2 speed (85CFM) which is way overkill for this cabinet... leaves look about the same as any other grow i've done. What do you suggest?
ITS EITHER size of the air bubbles.........................or not enough air.................or
.....too high water level in ur tank...........................................check it out👻...........pls......................to me they look like they drowning for some reason
