* MIGRO UVB 310 Fixture | 18 watt

This UVB light works amazing as long as you have a light that allows the UVB to penetrate past your light base and ballast etc. What I do is I put my migro array 4 in my tent the last two weeks of flower cuz I know that it has plenty of space to get to the canopy using that light. But I don't use that light during the budding phase because that light does not give enough par output to grow big colas the buds will end up airy and small. So what I do is I use either a Mars hydro TS1000 or viper Spectra 1500 throughout the budding phase and during the last ripening phase the last two weeks I switched the lights out with the migro array 4 and run the UVB 2 hours every day mid light cycle. Within a few days you will notice a huge difference in the smell of your grow and speaking from experience to taste of the flower is amazing.

I see some reviews saying the light is broken because it rattles. There is bits of metal inside the fixture that vaporize once turned on. That chemical reaction is what causes the UV glow. Every single one of these lights has metal rattling inside. It's too bad that people didn't do basic research and left a negative review. I do not own this product, I have the argomax equivalent uvb fixture. It also has the rattle, which again is by design. I hope this was able to help some people out dismayed by other reviews.

Upon arrival I noticed the box used to ship was damaged, the manufacturers box was damaged and the light bulb itself rattles. You can hear something rolling from one end of the fixture to the other, something is obviously broken on the inside. I have no issues with the product itself and love Migros products, it was simply damaged during shipping and not a product issue, more like a UPS issue as it seems to be a normal occurrence for UPS, but not USPS, which never arrives damaged. UPS, sucks.
