i purchased a 25inch, GE plant & aquarium brightstik flourescent. it puts out 33watts and 470 lumens. im hanging it roughly 3 inches from the tip of my baby plant (little over a week old) it was previously growing from natural sunlight on the windowcell. is it ok if i start it on a 24/24 light cycle? how long should i keep it on 24/24 or not keep it on? ALSO - is this light manageable for growing or was it a bad choice to buy it? THANKS
