that for a first time grower that cfl is the way to go allthough i would suggest getting a higher wattage when you get them because 2050 isnt no where near,it should take roughly 4,000 lumens for one plant so you would need at least two bulbs for the one plant and that is cutting it close because thats the bear minimum i would suggest getting lowest wat of 50 because depending on how many plants you wanna grow you don want to have to plud 50 weak bulbs were you could use one powerful one remember you can never have to much lightany way i my self buy 200wt cfl bulbs from ebay £30 each bargain producing 14,000 lumens each hope ive helped .
p.s if i have plz ad to my reputation by clicking on the scales in the top right corner thanks
