Okay, so that slow-ass bean has cracked, and one of the ones which did isn't doing anything in the cubes. Today I turned on my light to test what temps will be like, and so far we're holding steady at 86 degrees. We're having a late fall heat wave in the area, so I expect that temps will drop a little bit. This is a far cry from the last time, considering I couldn't close the tent fully without murdering my plants. So far, the fan upgrade has been worth it. I'll do another leak test of the ebb n flow system a bit later in final preparation for the transplant from my propagation chamber to the tent.
