DoctorJ Posted February 2, 2005 Report Share Posted February 2, 2005 I have an old aquarium with an incandescent hood. I wanted to use those screw-in spiral compact flourescent bulbs to grow some plants in there. I've heard of people doing it, but I'm having trouble finding any bulbs that have a decent colour range. The only ones I can find are soft white bulbs that say they have a 2700K colour temperature. Not so good for plants. Has anyone found any that have worked well? If so, where did you find them? Thanks! Quote Link to comment Share on other sites More sharing options...
AndyL Posted February 2, 2005 Report Share Posted February 2, 2005 Actually the warm white bulbs are fine for growing plants, they are probably better than some options as they have a nice spike in the red spectrum (which is what the plants use primarily for photosynthesis). 5000-6700k screw in CF bulbs do exist, usually you'll find them at places like Home depot, rona etc. Some of the homeopathic stores carry them (of course at a premium price) to cure seasonal affective disorder etc. Andy Quote Link to comment Share on other sites More sharing options...
Cichlid88 Posted February 2, 2005 Report Share Posted February 2, 2005 I've noticed that Pieces is carrying some of this type but am not sure of the spectrum, also pretty sure I saw some at Big Al's but again not sure of the spectrum. Best of luck Quote Link to comment Share on other sites More sharing options...
DoctorJ Posted February 3, 2005 Author Report Share Posted February 3, 2005 Thanks! If the soft warm bulbs work well, then I'll go that way because they are readily available and cheap! I'll look a bit more for some with a 5000-6700K temp, though. Quote Link to comment Share on other sites More sharing options...
freshmike Posted February 3, 2005 Report Share Posted February 3, 2005 I have also seen them at pisces, they are made by coralife, should be a good product. :thumbs: Quote Link to comment Share on other sites More sharing options...
African_Fever Posted February 3, 2005 Report Share Posted February 3, 2005 I've used them in my old incandescent hoods and find they work amazing. I've never actually looked to see the spectrum or anything like that, I was more concerned with which ones would actually fit in the hood (since some are rather bulky). All the ones I've used have made my plants grow like crazy, just ask Ty. Quote Link to comment Share on other sites More sharing options...
DoctorJ Posted February 3, 2005 Author Report Share Posted February 3, 2005 I tested one out that I had in my basement and it fit really well. It seemed to be a good and inexpensive way to retrofit an incandescent hood. Quote Link to comment Share on other sites More sharing options...
