Inside maybe a little slow but you will get it. It took a few more days for mine to get here but I planned ahead, so it didn't hurt. I got a 1000w the ballast is alittle noisy but works good. Don't forget the pic's, it give others something to compare to. the flouro's will help for side lights. Remember that you are only growing the top 1/3rd of the plants canopy without side lights.
