400W 3 strain grow

Currently in my flower room are
2 Detroit diesel
2 Chemdog
4 unknown clones

The DD and CD are clones, as are the unknown strain.
I grew out some seeds i got around christmas '09 from
a friend and really liked the weed so this september i germinated
the last of them, and the single female i ended up with became
a mother.
My plan is to clone and grow from this mom for the next few grows.
These first four clones were all topped before they went into flower.
The DD and CD are six weeks female and the four other clones went into the
flower room six days ago.
A few pictures of the plants, some in the flower room, some of the clones and mom
in the veg room just after topping, a week before going into flower.
I use the fox farms line of products in my grows.
Comments/questions welcomed

How close do you keep your light to the tops of the plants? and what temps do you run? Just asking because I'm trying to sort out some things with my 400w. Anyways the plants are looking very nice man, definitely healthy. Good luck with the rest of the grow.

The light is 10-12 inches from the plants on the sides and 12-16 inches from the clones directly under the light.
As they finish their verticle growth, they will of course get closer than that. And i may move them even closer.
If i do not run my extraction fan (300cfm) ambient room temps during winter are 79-82 and 86 under the light.
With the extraction fan on, room temp drops to 73 and under the light it drops to 77.
I can get away with not running extraction in the winter, my plants handle the heat pretty well, i also have 3 additional
fans in the flower room moving the hot air around, and the flower room door stays cracked open 3-4inches during lights on.
