The Iceberg 12.0 Eco from Korona is a powerful portable air conditioner perfect for growers looking for serious cooling in large setups. Equipped with a cooling capacity of 12,000 BTU, it's designed to handle rooms up to 42 square meters, meaning it’s ideal for medium to large grow tents, garages, or indoor grow rooms. You get three functions in one — cooling, dehumidification, and ventilation — allowing you to easily fine-tune your environment. With adjustable temperature levels between 16°C to 31°C( 61°F to 88°F), and an Energy Class A rating this AC operates efficiently with lower energy use. Its built-in caster wheels and compact frame make it easy to move around — and it comes with an integrated timer and remote control for added convenience. For smaller setups, check out the Iceberg 7.0 Eco or the mid-range Iceberg 9.0 Eco — each offering the same great features with a lower cooling capacity.
