jn Posted September 13, 2007 Report Share Posted September 13, 2007 Do most red plants prefer more light than green plants? Quote Link to comment Share on other sites More sharing options...
ej Posted September 13, 2007 Report Share Posted September 13, 2007 As davidb corectly points out it can be iron deficit, but also lack of light, when you mention red plants do you mean Alternanthera reinecki "Red"? as this plant require lots of light. Best of luck. Quote Link to comment Share on other sites More sharing options...

evilknieval69 Posted September 13, 2007 Report Share Posted September 13, 2007 Be more specific then 'Heaps of lighting'. Red plants need much more light than green plants to thrive and stay read..... Quote Link to comment Share on other sites More sharing options...

alanmin4304 Posted September 13, 2007 Report Share Posted September 13, 2007 What are the red plants you are growing? Many red plants are not aquatic plants and will struggle to stay alive no matter what you do or how much you spend. Years ago I used growlux and soft white tubes together (still use that combo on some tanks). Now it is fashionable to use daylight ( 6500K). Growlux (blue spectrum) tends to make plants squat and compact while red spectrum makes them tall and scrawny. This is more obvious when plants are grown emersed. Some people say growlux encourages algae. They are also about 4 x the price of other tubes. Quote Link to comment Share on other sites More sharing options...

SpidersWeb Posted September 13, 2007 Report Share Posted September 13, 2007 6500K daylight tubes can be had at your local electrical wholesaler for $7ish Where available I do *prefer* to go with Powerglo because it has lovely spectrum spikes at the right points, but thats more like $20-30 rather than 7. I've had trouble with red plants too. I'd be more inclined to look at possible a metal halide fixture if I wanted to do more reds (at least to give it a go).

jn Posted September 14, 2007 Report Share Posted September 14, 2007 And yes you can buy iron test kits. Your local shop should have them.. petplanet.co.nz also sells them and I'm sure there are others. Quote Link to comment Share on other sites More sharing options...
