Mars hydro uvr 45

There's nothing wrong with this except I circled the part that's missing the backing it's just the plastic piece I wrapped it with electrical tape it doesn't affect the product at all it works just fine. It's UVA and IR light it's UVA so you can leave it on with the IR for the whole 12 hours of flowering unlike UVB light which would be 30 minutes in the morning in the afternoon and in the evening. But it's a steal at the price just missing the back piece again I circled the part I'm talking about doesn't affect the item impeccable for everyday use. top-grade materials and excellent craftsmanship ensure long-lasting durability.
