actually as it turns out, flood tables seem to like higher temps anyway. My plants are proof. They have never looked greener or grown so quickly once I got everything dialed in. As I was waiting for a bigger fan my temps routinely ranged in the mid 80's in the canopy and 78 to 80 for res temps. The plants seem to like hotter climates and ebb and flow require evaporation to work properly, so I'd say they were made for each other. I only have to worry about temps for another couple weeks anyway. Pretty soon, high noon will have passed and we can get back to normal growing weather.
