P.S. I am aerating the reservoir with a 2-outlet aerator running to a bubbleystonage. I put a block (estimated 16 oz.) of purified ice in once or twice a day to keep the water level good (3-4 gal) and reduce temp from 80ish to 70ish. This makes a very sudden reduction in H2O temp. Every day...
So this is my second grow. [Note: My first grow was in a bucket using various different aeroponic setups. My first grow failed due to reservoir-temp issues and clogging/failure of the watering system. So I basically made an entire new grow room in my closet (which is what this post is about)...
