Hoody Posted May 27, 2008 Report Share Posted May 27, 2008 I'm planning on upgrading my light's soon, but as a tempory fix for my not so happy plant's, would leaving my existing light's on for longer help them?? Quote Link to comment Share on other sites More sharing options...
alanmin4304 Posted May 27, 2008 Report Share Posted May 27, 2008 It may do but it depends how long they are on at present. They do need a rest period though so you cannot leave them on all the time. Quote Link to comment Share on other sites More sharing options...
Simian Posted May 27, 2008 Report Share Posted May 27, 2008 12 hrs a day is about a good average Quote Link to comment Share on other sites More sharing options...

whetu Posted May 27, 2008 Report Share Posted May 27, 2008 What are your existing lights? What is the depth of the tank? What plants do you have in there? How long are your lights on at the moment? Generally leaving lights on for a longer time is no substitute for intensity and appropriate spectrum of light. Depending on the age/type of lights you have now, you might be able to get better results by simply changing to fresh tubes/bulbs - the cheap ones from the hardware store rather than the expensive ones from the pet store.
