Remember,this is my first grow attempt, lol. The trellis is the only training technique at the moment, besides a few strings every once in a while. I still have plenty of room so the problem is not that I'm running out of space, just that the light won't reach the half under the trellis in a few days if the top grows as fast as the rest has been growing. I'm not even sure that it will actually be a problem getting light there since it reflects throughout the room, but I will put some better pics tomorrow to show what I mean.
