View Full Version : Will actinic light harm plants?

02-23-2008, 01:56 PM
I bought some compact fluorescent bulbs (10w) the other day for one of my tanks and they're 50/50 white light/actinic. The white light is fine, 10000K, but I'm wondering of the actinic will harm the plants.

At the moment, I've got a few Java ferns in there and 1 stem of Hygrophila.

Thanks all.

actinic only benefits corals, it wont help your plants or hurt them

Its not going to hurt them, but it isnt going to help them, but the algae can use it, then the algae can hog the nutrients. So in a way, I guess it can hurt them.

What are actinic lights?

From what I've been able to gather, they're higher intensity and they put out a different spectrum of light. They're mostly used for saltwater setups, I think that corals need that kind of light to grow properly.

I bought them 'cause at $5 a pop for a compact fluorescent, you can't go wrong and the other cheap lights weren't that good ...

In the end, I don't really need all that much output, I've got two of those lights on a 5g tank with a few Java ferns in them. Should be ample for them.

Thanks for the answers.
