Hi all just wondering if any can help me decide when to change my metal halide bulbs some of them look alot whiter than a new one which looks blue ?
It highly depends on bulb quality. Hortilux is very high quality and recommends mh to be changed at 6 months at 18/6 for best growth. I give a cheap mh bulb maybe 3 for best results.
for not the best results you can add months to this estimate. You may not even notice unless you are getting the most out of them.
Hey MiMed, I've never used a MH light through my grows, can you tell me why you use one and when you use it? Is it worth it to use both ?It highly depends on bulb quality.
