Has anyone tried this light for a grow? If so, I’m particularly interested in how it performed for flowering. I’m considering putting one in a 4X4 tent.
I haven’t used that particular light but I did veg a very healthy plant in a 3x2x6 with a dimmable viparspectra 300w. I’m not sure about flowering, I’m sure it would have produced an ok yield but they are very heavy on the blue spectrum. So I’m flowering with a 600 hps. Not sure if that helps you any , but thought I’d share.
Viparspectras have an extremely blue hue to them and I dislike them for this reason, its just way too much blue to grow with, no need for it. I wouldn’t purchase it. There are better options
It will definitely work
Hogmaster-
Do you know anyone that has used this light for flowering? As a previous poster has said, many of the Viparspectras seem to be heavy on the blue. I don’t think this particular one is, at least not when you crank up the flowering rheostat. I just don’t want to get in the situation where I have to switch to a HPS to get a decent yield.
Hmmmmmmm I’m running a VIPARSPECTRA Timer Control Series VT450 450W LED for my first Auto flower grow and now you all have me worried for my flowering 
They wouldn’t sell the lights they do if they didn’t work do they Advertise as veg only does it have a veg and blooms switch they will work but there are things that work better all trial and error I use meizhi leds they where the cheapest thing I could find at the time and now I have 7 of them
I have faith in you 
Please let us know how your flowering goes. I’m very interested.
