I see a lot of problems result from high water temps but does anyone know how cold you can go whilst still maintaining a healthy root system?
Im not 100 percent sure mate but i read somewhere to keep water temps between 18-22 degrees celcius

A: 62-68°F (17-20°C). Above 72°F (21°C) and dissolved oxygen (DO) dips too low. Below 60°F (16°C) and plants tend to slow their metabolism as they "think" the season is changing. Some growers use this to their advantage and reduce nutrient temperature towards the end of the flowering stage to aid in ripening.
