Half of my quantum boards are equipped with additional far red IF and 3500k spectrum, the other half are just straight up 3500k with no red, no UV. Yeah you can use this feature to your advantage if harnessed properly... With sativas, especially closer to pure sativas, its a great advantage without altering much that i do because the plants have plenty of time to get large enough and these lights prevent the typical stretch. For the first few indicas I ran with these lights the plants wound up like dwarfs, very small. I took notes and realized I need to veg longer! I use to us CXB3590 Cob lights, these are more efficient.Is it really an issue to have a short/shorter internode distance in case of Haze that can reach 6 meters high in nature ?
Can't you really use that "feature" to your benefit ? And what about supplementing the electromagnetic spectrum with some additional UV-A source ?
