I have a 60w CLF and I also have a 400w Mercury vapor. When should I change the lights? Is it when the first point leaf comes out? or 2nd set of point leaf is born?

Also how far should I put the 400w from the plants? the light does not get hot at all. Its at best a little warm.

Damn people still use those,you can put seedling under HID lights soon as they pop i never use cfls for seedlings,this is probably why my plants look
like a plant at 2-3 weeks in the first week,just keep them 18-36 inches away at first.

36 inches from a 400w is that to much light for just 2 seedling?

I have a squirrel box atched to it. With out any colling its imposilble to tuch the hood. But with squirrel box pulling air thru a sealed rood its just lightly warm.
