my indoor 1000w hps grow was showing slow growth. outside is 32 degrees f.
Since I always get slow growth in winter. the inside garden temp is controlled around 75 deg. Finally I bought a titanium aquarium water heater. Its set for 82 degrees.
reduced my ppm to about 33 percent and increased my flood frequency to every 6 hrs lights on for vegging. (small clean pumice for medium) Within 3 days everything took off. my conclusion is that rootzone temps work very well when higher than canopy. If I were doing dwc, id keep water temp lower to keep more o2. But eeb n flow. Reseroir needs to be around 80. for max growth. cooler res temp seems to stunt some growth.

That may work well in cold weather environments but not in warm weather environments. I had problems with that affecting my hydro plants in the summer where my water temps got higher than 75f and caused my plants to suffer. I had to buy and set up a chiller to keep the water around 68f for them to stay happy, but that was with air temps in the low 80s.
