Need some advice - DWC root issues?

Most of it will be in my HPA thread.

Adventures in Hydro #2 - LP Aero/NFT mash-up - or - switching to HPA?

Bingo!! The temp in the middle of the chamber was at 68.5 and falling when I went to move the temp probe. I moved it to the bottom of the chamber first, and it read 66.4. Then I moved it to the net pot, and it read 74.6!! Id bet those temps at the top could have been even higher when the heater was on full. I have to say, I was not expecting that large a temp differential. Thank you for the suggestion to check that. I might not have actually done it if not for your comment

I might start a new thread when I start the new seed in the system. That thread is getting a little long and has wandered all over the place ) I will let you know and post any new links there.
