How much light intensity ?

Hey folks - I'm a medical user and now first time grower. I hope there is an experienced grower who can perhaps answer my question:

I want to know how much light my new plants can take as they grow. Since varying light distance from the plants is the only way to control light intensity, I wonder how close to the 400 W MH my children should be at various ages. Right now they are two weeks old - - should they be 36 in.?, 30 in.? Should I be decreasing the distance a little each day? Every other day? Decrease it by how much each time? What is the limit as far as distance? I'd rather not determine that by trial and error.

Many thanks to any responders. Peace and Love.

your light should be far enough away so if you put your hand under it at the same height of your plants, your hand will be comfortable ie doesnt burn you. with a 400W that should be somewhere around 12" give or take
