Pro Tips

✓ T5s are cheapest but run hot — keep them 2–4 inches from seedlings
✓ LED panels use 40–60% less electricity than T5s for the same output
✓ Full-spectrum LED bars are ideal for veg and early flower stages
✓ Set timers to 16 hours on / 8 hours off for most seedlings and leafy greens
✓ Keep lights 6–12 inches from the canopy and raise them as plants grow
