Hi, stupid question, I know. I have a 20gal long aquarium and a NICREW Classic LED Plus light. According to their website, this light is 22W, 1150lm and 6500k. From my research I know that this light is on the low end of wattage for plants, but I don't have the money to invest in a twinstar or ADA grade light. Could I simply add another one of these to my tank to double the light the plants get? It seems so logically, but I want to make sure I'm not missing something obvious here. I want to increase light intensity to bring out better colors in my plants and to increase growth. Thanks.
