FAQs

What are fluorescent grow lights and how do they work for grow setups?

Fluorescent grow lights (like T5, T8, or CFLs) emit a broad-spectrum, low-heat light that’s ideal for seedlings, clones, and early veg. They’re energy-efficient for low-light needs and gentle enough to avoid stressing young plants.

How many fluorescent lights do I need for a 2x4 or 4x4 grow space?

For a 2x4, a 4-lamp T5 fixture is usually sufficient. For a 4x4, step up to an 8-lamp fixture or use multiple fixtures to cover the area evenly. Make sure PAR levels match your plant needs and stage of growth.
