just a piece of advice... for growing Home Depot SUCKS!!!! I tried there first, since they are obviously the easiest.... not happening! The HPS and MH lights they have there are not the right type. Most of them are for outdoor motion lights... What you need to do is find the closest hydroponics store, (thats what I did). In most places there is atleast one within drivable distance... just look them up online.

If a hydro store (or similar) is unavailable in your area, then that sucks... in that case stick with tons of fluoros and just keep adding more.

peace and best of luck,
