Cricketman Posted January 13, 2010 Report Share Posted January 13, 2010 lol! nice banner.... you got yourself a symbol too?? as for the actual OP... I have no idea, I imagine the more intense the light, the bushier the plant. as for actual wavelengths, would depend on the plant species. thats about all I can offer sorry....

wilson Posted January 13, 2010 Author Report Share Posted January 13, 2010 I shall answer your question if you tell me what plants you are trying to grow! well i haven't fully decided yet :oops: plants that i like that dont grow how i want them to are Stargrass, Ambulia, Ludwigia, because they grow very fast and the lower leaves die off :evil: other plants ill have are a sword plant and the usual java fern / Anubias in the mid ground and a Glossostigma carpet in the front if the lights strong enough Quote Link to comment Share on other sites More sharing options...
phoenix44 Posted January 13, 2010 Report Share Posted January 13, 2010 ok. so are these high output light fixtures? Use 10000K and 18000K in combination with each other. the powerglo (18000K) is specifically developed to have both red and blue spectra. the blue encourages flowering and compact growth and the light also encourages red growth.

Floater Posted January 13, 2010 Report Share Posted January 13, 2010 How would a 15000k Marine white T5 54watt bulb do in this case? Quote Link to comment Share on other sites More sharing options...
phoenix44 Posted January 13, 2010 Report Share Posted January 13, 2010 How would a 15000k Marine white T5 54watt bulb do in this case? made for corals. its peaks won't be right for plants, but you can always try it out. Quote Link to comment Share on other sites More sharing options...
Floater Posted January 13, 2010 Report Share Posted January 13, 2010 made for corals. its peaks won't be right for plants, but you can always try it out. I have similar plants to Wilson and the pet shop ordered in the wrong size bulbs the only one they have in the correct size is the marine tube, I think I will just wait until next week and get a Day tube to be on the safe side.

wilson Posted January 13, 2010 Author Report Share Posted January 13, 2010 thanks everyone for the help ill look for some 10000K and 18000K bulbs :bounce: Quote Link to comment Share on other sites More sharing options...
phoenix44 Posted January 13, 2010 Report Share Posted January 13, 2010 just make sure the 18000K tubes are powerglos. they are expensive. usually twice or thrice the price of normal pet shop priced tubes. worth every cent in my opinion. for results see my thread in this section.
