New Indoor Grower

So i bought 2 clones at the club Today, one is a a 10 inch tall clone, the other is about 6 in. (i live in cali) and i need 2 know what i need 2 do to grow it. I Have my closet as a grow room, its wrapped in Mylar, and i have a 150W HPS bulb http://ecx.images-amazon.com/images/I/31s1wf1jx+L._SL500_AA300_.jpg Now i need 2 know what precautions 2 take. For Soil, i use 1/3 peat moss, 1/3 vermiculite, and 1/3 perlite. Ive potted, put them in soil, and watered them, and put them under the light. What do i need 2 do next!? Humidity dome? what? And how far away should i put the light?
