When is it safe to put a 400w hps on my babies?

hello everyone, i have two feminized og blueberry girls that are about 11 days old and are currently under a 4ft. 40w plant/aquarium floro. I have a 430watt hortalux hps as well. I just want to know what everyone thinks is a good size to put the 430 on them. thanks

sooner the better.. start out at 2ft away.

Hell yea let it rip. Or when you transplant to biiger container let it rip.

i start my seedlings straight out under my 400w mh , so i guess you can start yours whenever.

Just keep the light at bay , 2 ft should do it. Otherwise theyll burn like burning burners.

thanks guys! they have already been transplanted to 5 gallon buckets...so looks like im going to put it on them now. i'll have to start a journal and post some pics soon.
