The Aelius 300 is great for propagation and small spaces and is our best seller due to its ability to cover both large and small cultivation footprints. It’s compact size, at only 1010mm (39.8in) makes it the perfect fixture for residential operations, easily fitting into a 4′ x 4′ growing tent. However, when combined with multiple units the Aelius 300 really shines as its effectiveness is multiplied, providing full coverage for large operations, long tables or rolling racks.
