200w+ CFL scrog in the attic

What's with the extreme high/low difference near the end of the graph? It looks like your hottest day and coldest night were on the same day. Am I reading the graph right?

There are a couple different factors affecting that. First, there's the problem I mentioned a couple months back, linked to my light cycle and air conditioner. Since the grow box was in the attic AND tapped directly to the house's central a/c, it got coldest when the thermostat was forcing the a/c to work hardest, i.e., daytime, which happened to coincide with my "lights out" period. The attic and grow box got hottest at night, when the a/c wasn't working so hard and the lights were on. This was aggravated by really hot temperatures, when the a/c ran nonstop all day and the overnight lows were still pretty high. The other major factor was that I stopped taking daily readings for the latter part of the chart, so those high/low data points aren't for a single day, but rather for the entire period between taking readings. You can tell based on how far apart the dots are how many days there were between readings. So, a high and low reading that were taken on the same day doesn't mean they happened on the same day, it just means that during that period between readings I had both the highest and lowest temperature.

In other news, I decided to take some pictures of Snap, the clone I described above. As I said, this plant was grown under a single 26w bulb for most of its life, and then a single 42w bulb for just the last two weeks. Here are three pictures zoomed in to different degrees:







I'm debating between harvesting pre-move and moving the plant and harvesting later. Either way should be feasible, since she's such a small plant.

Let her go all the way man. She looks really nice, and close.
