Ok.. Only basic equiptment.. How much money do you want to spend?

If you can, buy a MH for veg, and HPS for flower..! <-- a bit expensive..!

If not, just get a few of the highest wattage CFL's you can find.. Cool white for Veg, and Warm white for Flower..!

The room shouldnt be to big, the loss of light will be to big..!

Oh, offcourse you will need soil!

Then, for flower, you will need a timer..!

And you need a fertilizer for Veg, and one for Flower..!

Hope this helps..!
