OCR 645 – Professional-level grow tent for serious CO₂ projects

With its generous dimensions of 6 meters long, 4.5 meters wide and 2.4 meters high, the OCR 645 grow tent is a top-notch solution for anyone who wants to grow professionally or semi-professionally. Part of the OCR XXL series, this tent is specifically designed for growers who seek maximum efficiency, yield and control over their growing environment – including the use of CO₂ systems and high-end lighting.

With a floor space of as much as 27 m², the OCR 600 can accommodate a complete lighting plan according to the OCL XXL Series concept, including powerful 1000W double-ended fixtures or high-output LED systems.

Robust frame & load-bearing construction

Like its bigger brother (the OCR 1200), the OCR 645 is constructed of a solid 25 mm thick tubular steel frame with extra strong metal corner pieces. This structure can withstand a load of up to 120 kg, allowing you to safely mount heavy filters, lighting and air conditioning systems effortlessly. The stability of this frame makes it ideal for long-term, intensive growing cycles.

Rubber bases under the posts protect the surface and ensure stable positioning, even on uneven floors.

High quality 1680D canvas with diamond reflection

The exterior of the OCR 645 is made of ultra-thick 1680D Mylar fabric – lightproof, abrasion-resistant and easy to wipe off with a cloth. On the inside, the fabric has a diamond reflective layer, which reflects the incoming light back to the plants in a highly efficient manner. This increases photosynthesis, encourages even growth and minimizes hot spots or shadow zones.

The fabric is also heat-resistant, oil- and moisture-resistant, and tear-resistant – perfect for intensive and long-term indoor cultivation.

Double waterproof PVC bottom

Like every OCR tent, the OCR 645 features a removable, form-fitting insert made of 0.6 mm thick PVC film. This bottom is tested for a water capacity of 2200 liters, which eliminates leaks and water damage. Ideal for growers working with hydroponics, DWC systems or manual watering.

Completely CO₂-ready and modularly linkable

The OCR 645 was developed with climate-controlled cultivation and the use of CO₂ enrichment in mind. With 14 air hose openings of Ø 350 mm and 10 cable passages of Ø 10 mm, the tent is perfectly prepared to connect ventilation, cooling, power supply and climate equipment such as OptiClimate or Nagano systems. All openings have double sleeves for a light-tight, secure seal.

In addition, the OCR 645 is linkable with other OCR tents, making it easy to build a larger grow room or expand existing setups. Thanks to the innovative 1+1=3 principle, your air conditioning system becomes up to 50% more efficient as airflows and heat distribution work together optimally.

User-friendly & professionally executed

Despite its XXL size, the OCR 600 is quick and easy to set up thanks to its smart click system and clear assembly instructions. The tent features multiple doors for easy access, industrial zippers and a clever design that remains completely light- and odor-free. You will receive the tent in a discreet package that is safe and unobtrusive to transport.
