Hydroponic and DWC setups need nutrient solution kept at 65–72°F to prevent root rot and maximise oxygen uptake. A dedicated water chiller is often more reliable than ice bottle methods. We cover compact inline models suited to grow tent setups.
Compact models that fit in grow tents and cool DWC reservoirs reliably.
