Reliable Full-Spectrum Power for 4×4 Grow Tents & Indoor Gardens

The Mars Hydro TSW 2000 is a proven, best-selling 300W LED grow light designed for home growers who want consistent yields without excessive heat or energy costs. Ideal for grow tents, closets, cabinets, and plant shelves, it delivers powerful, evenly distributed light for healthy vegetative growth and dense flowering.

Why Growers Choose the TSW 2000

• Optimized Coverage: Supports up to 4×4 ft in veg and 3×3 ft in flower — perfect for 4–8 plants.
• Energy Efficient: Replaces a 400W HPS while using just 300W, reducing electricity use by up to 25%.
• High Output Performance: Delivers up to 776 μmol/s PPF with a PPE of 2.6 μmol/J for strong growth and improved yields.

Full Spectrum Designed for All Growth Stages

The TSW 2000 emits a balanced spectrum across the 400–700nm PAR range, combined with supplemental IR (730–740nm) to support flowering and bud development. This spectrum closely mimics natural sunlight, promoting efficient photosynthesis from seedling through harvest.

Patented Reflective Hood for Even Coverage

The patented reflective hood captures and redirects stray photons back toward the canopy, increasing usable light and improving uniform coverage across your grow space.
