Things look a bit better today . I cut a new intake hole last night in the wall near the plants. There is no dedicated fan there yet, but I could tell the temps were lower this morning , and the air felt 'fresher'

Any sugestions on getting them to space out a bit between nodes. On one of the plants , I can count at least 5 nodes in 3 inches of growth, and all of those nodes are starting secondary growth now...its like a rats nest in there
