Honestly, a 400w mh is more than enough to veg seedlings & clones, unless you have a large space with lots of plants, then maybe 2 400w mh set-ups would be needed, but really a single 400 mh is perfect.
Hard to say exactly when to put the seedlings under a 400mh, I'd assume once you have 3 or 4 levels of true leaves, they should be good to go. Seedlings tend to stretch, so using flourescents, you can keep them nice and close to the seedlings to help mitigate the stretching. You also wanna make sure they are strong enough to acclimate to the intense light, last thing you want is a tray full of seedlings getting a bunch of burnt shriveled leaves haha. However, the sooner you can get them ready for the MH, the faster they will grow and the faster you can get to the 12/12 stage.
