Day 54 indoor- A little light trouble nearly avoided

Day 54 indoor- I unzipped the tent and the light was out. I kinda panicked and immediately blamed the timer. Unfortunately reworking the timer did not solve the problem. That’s when I checked the light itself. I pushed the “on” button again and the light went on, crisis averted. Other than the light snafu, everything looks great. The plants are massive and have just about outgrown the tent.
