Choosing the Right Wattage for Your Space
LED grow light wattage should scale with your grow area, not just your budget. As a general guide:
- Small tents (2x2 to 3x3): 100-200W fixtures
- Standard tents (4x4): 300-450W fixtures
- Larger tents (5x5 and up) or commercial rows: 600W and above
Browse our wattage-specific collections — from 0-99W lights for propagation through to 800W+ commercial fixtures — to find the right fit for your space.
Full Spectrum vs. Targeted Spectrum
Most modern LED grow lights use a full spectrum output, mimicking natural sunlight across the growth cycle. This means one fixture can take a plant from seedling through to flower without needing to swap lights. If you're comparing full spectrum vs. single-spectrum grow lights for plants, full spectrum is generally the more flexible, lower-maintenance choice for most growers.
PPFD and Hanging Height
PPFD targets shift as your plants move through their growth stages, seedlings need far less intensity than a plant in late flower. Getting your hanging height and PPFD right at each stage protects your plants from light stress while maximizing growth.
