I currently have a 2x4x5 tent with a 400w hps running and was considering adding a 90w UFO led using 3w diodes for supplemental lower node lighting on one of the shorter ends of the cab. Any thoughts? Here's pic of my current set up. I've done plenty of research and I know that they are good for veg growth but produce fluffy buds and I was hoping to gain shorter internode space by combining the hid with led lighting. If I add these 90w I'd be at around 60w/sq ft.
