Measure the length, width and height of the intended location. Leave room to open the door, reach your plants and run the ducting. Inside the tent, pots, light hangers, the light and filter also take up space. Choose the tent size before comparing light wattages.
Starter kits use Mammoth Lite tents. Professional kits are built around Mammoth Pro, with different lights across the range. The Pro 80 includes a Lumatek Attis 200W Pro; the Pro 120 includes a DimLux Xplore 730W 3.0. A series name alone does not identify the supplied light.
Ultimate kits with Mammoth Elite S.A. or OCR Premium tents add under-canopy lighting, an OptiClimate system and CO₂ controls. Plan power, climate equipment and controls as one installation. Check the requirements of each supplied model and have the site facilities assessed.
