ufo 200watt would be a good bud inhancer red spectrum, I run a 600hps along with a 600watt viparspectra and 200watt ufo seems to do goodRunning a Viparspectra model 1200W ( 600 watt ) in a 4x4 grow tent. Need a great red spectrum kicker to kick up the budding.
Never tried a COB light I HEAR good things about them. I would be willing to try a demo light if that's what you're asking and do a journal based on that light/lights off needed winkHi Scrogster,
Consider a 1750K COB light? A lot of PAR output and a red leaning spectral output, well suited for flowering and as a supplement to boost the power of your existing setup.
If you have questions, let me know I am happy to help.
Have a good day.
The Viparspectra does fantastic in veg.If I may..
The Viparspectra you have fully covers about 2,5 x 2,5 in flower, and it doesn't have enough red (don't know why they designed them that way....)
More light is the key here, bathe your entire canopy in +800 PPFD and you're gonna finish in the money for sure
