When you are using a split air conditioning system for your hydroponics you will get a certain length of hose depending on which units you decide to go for. The OptiClimate 3500 Air-cooled System features cooling hoses that come in varying lengths depending on the model type, however you may find that if distances are greater than for the hoses supplied you will need to get some extra hose to bridge the gap between the split units. An 8 metre hose (consisting of two hoses) comes with the OptiClimate 3500 Air-cooled System as standard, while the OptiClimate 3500 Air-cooled System with Extended Reach come with 15 metre hose (consisting of two hoses). You can extend the split unit hose by a further 7m to a maximum of 15m, but you can get less as the extra hose comes in metre lengths.
Cooling hoses come as standard with all OptiClimate systems.
An 8m hose which can be extended in metre increments up to 15m.
