ok all i want to know is does a 42 watt cfl penatrate deeper vs a 23 watt cfl? i asked this in another forum but everone kept sayin if it has more watts then it has more lumens. i aready know that so dont reply if your goin to say that, lol. anyways im going to do a scrog grow in two 18gallon rubbermaid totes one stacked on top of another. i want to either have 6 42 watt cfls or 12 23 watt cfls depending on what you guys tell me. the reason i would rather want more little cfls vs fewer amounts of bigger wattage cfl is i think that way you would not be waisting as much light. if the bigger wattage cfls has the same panatration level as the lower wattage cfls then that would mean the big ones just have more lenth of tube coiled up, so then you would have have all of the coils behind eachother and you would just be waistin light. the only way you can have good results with cfls is you keep it as close as you can to it correct? with more number of smaller wattage cfls you would have more parts of the bulb closer to your plants and more evenly too so you would have more eficient use of the light especialy if your doin a scrog right? i really hope you guys understand what im trying to say. now if the higher watt cfls have more lumens because of the actual light comeing out of the tubes instead of there just being MORE lenght of tubing, then i would understand why peaple prefer to use higher watt cfls. so correct me if im wrong about anything i just said. for whoever read the whole thing thanks for reading this long boring ass ****. so someone school me
