Finally got light for the 90g aquarium. I ended up going with a two bulb T12 fixture and bough two phillips T12 40watt daylight deluxe bulbs 6500k. Wondering what I can grow with these.
Not much. You're going to be limited to the very hardiest of low light plants, which will probably survive but not put on much visible growth; Java ferns, mosses, Anubias, POSSIBLY some swords or crypts if they're planted directly under the bulbs...
If you could add a Coralife T5NO fixture from www.BigAlsOnline.com
, this would greatly increase your plant options yet still keep you in the low light/no CO2 needed range.
