Want maximum and consistent yields all year round? Get an OptiClimate 3500 Split Air Conditioning System.

You can create and maintain the ideal temperature, humidity and CO² level for optimum growth.

You can synchronise it with CO² equipment and up to 6 x 600W lights or 9 x 400W lights via a Dimlux Maxi Controller.

It's easy to use, with separate settings for night and day. To prevent bud rot (botrytis) and shock, plants are slowly eased into each mode.

Your OptiClimate can quickly and automatically detect and respond to environmental changes.

Your system will help keep pests out, and keep CO² in (efficient!) - very little air is exchanged.

Unlike the OptiClimate Water Cooled System, the split system doesn't use water! It's the only option if your water's at a premium.
