Hey guys,

I've been vegging and flowering with T5's for a while now, on the side of HPS bulbs. I was just wondering, like HPS lights do T5's lose lumens by using them to flower more than a few times?

Some more than others..the light meter that I bought off Ebay for less than $25 has paid for itself.
