Grow Mediums New autopot/coco question

[HemiSync]

My tent is 39"x39"x70"

I tried an airstone in the res but it messed with ph so I removed it. I would suggest a small pump to circulate but to aerate.

I too had the same results with an airstone so discontinued use. I tried a pump, but the only one I had around was too powerful and threw the water above the surface causing it to aerate and the pH to rise. Now I just stir it once a day when I measure and record the levels.

I was having pretty good luck with a small circ pump on a timer. Came on three times daily for five minutes but, while I was away, the res dipped below the pump and cooked it. Now, I do what you do and stir once a day or thereabouts. Getting ready to fill my res today for the first time this grow.

Always a good feeling when you can turn on the res.

Thanks for the advice , I added a pump and ran plastic tubing so that it would return at the top.
I placed 2 90° fittings , it kinda looks like a candy cane. What are you seeing for resevior temperatures?
