T5s are widely used in commercial settings for propagation due to the fact they carry several advantages over other types of lighting. For one, they are only 6cm deep which means they can fit neatly into most spaces, and they are perfect for growers looking to fully utilise their growing space by housing multiple propagation shelves vertically.
Secondly, the fact most systems use a number of T5 grow lights in a parallel array offers a substantially even spread of light, ensuring that all plants, including those located at the edge of your grow room, receive plenty of light.
Finally, T5 lighting systems come in a variety of sizes, use very little power, and output minimal heat, meaning they are suitable for use in any sized grow room and can be safely hung just a few centimetres above your plants without causing any issues. Low power consumption also means they’ll save you money on electricity costs over CFLs (small difference in cost) and HIDs (big difference in cost).
