The stretch has definitely begun. No issues whatsoever. I turned the lights up to 250W and bumped the PPM to 950. Thinking about adding another LED to tent - these things are going to be out of control!
The GSC in the 64L res is almost exactly on the same schedule as the 1L, which is 5 days older. the 1L is obviously in the lead in terms of size, but the 64L isn't far behind. I honestly think they'll both end up being almost identical...
