hanging height

That's an older style light with blue purple spectrum. Its a bit out dated and not the best but it will work. I would use that thing with veg+bloom on all the time and then dim it down if it has the option. If not just adjust the hang height. Its all about DLI you want around 35. 40 is upper max for most home growers. Google about DLI and familiarize yourself with it. If you have the option to get a diffrent light I would though. www.youtube.com/watch This is a good link to watch and goes over a lot of things. Good Luck!
