yea i dont worry too much, go digital tho if u go bigger, MUCh more efficent, and u can use hps & mh bulbs! or acualy there r more! im lookin into getting a 10000k UVA bulb fer the final weeks of flowering, or all around.
i was thinkin of goin areo, but i dont feel like werkin all crazy on PPM and stuff, plus its easier to get a NICE aroma and taste out of soil. not sayin its fer sure better, but its fer sure easier!
