For successful indoor cultivation, a high-quality LED grow light for your grow tent is essential. Light is the most important factor for healthy plant growth, strong flowers and a high-yielding harvest. While HPS and MH lamps used to dominate the market, modern LED solutions have long since taken over – more efficient, longer-lasting and specifically matched to plants' needs. An LED grow light produces significantly less heat and can be positioned closer to the plants. This ensures even lighting throughout the grow tent and reduces the risk of burns.
Not sure which LED fits your tent? This collection groups fixtures by the tent size they're intended for. Right now it contains two Fortis models: the Fortis NXT 720W with 2.7 µmol/J and an integrated driver, listed for 120x120 cm tents, and the Fortis BYD 1000W full-spectrum light with 2.8 µmol/J for 150x150 cm and larger. Matching light to footprint avoids dark corners and wasted power, and helps you plan extraction for the heat the fixture adds. Use the sub-collections LED for 120x120 tents and LED for 150x150+ tents, see all full spectrum LED lights and read the right LED wattage for your tent.
