Because our oxyCLONE systems do not have spray jets that clog or overpowered pumps to heat up your water, your oxyCLONE will generate less heat than other cloning machines. Many growers consider 77°F as the ideal temperature for plant growth, but your oxyCLONE will perform well at temperatures ranging from 72-82°F. Reservoir temperatures will usually be 3-5° higher than room temp, so these systems work best with ambient temps in the low to mid 70s.  Temperatures will increase if water levels get too low.
