Transplanting Question

I'm goin to transplant my plant very soon..is there anything i must do to the soil first or can i just put the soil in the pot and put my baby in there.
I heard I had to get the soil ready by soaking it with water a few days ahead and spraying it with nutes, then waiting till the soil is almost dry then putting the plant in there..

any help would be great

Depending on the type of soil you might want to amend it a little, but other than that just go for it. I wouldn't soak the soil though. I like to transplant into semi-moist soil and give it a day or so before i water it thoroughly. It forces the roots to spread out quicker in search of water. I can't site a source for that info, but it hasn't failed me yet.

I say water the night before then the next day wait till the lights are about to go off then transplant

Yeah leave the plant in the dark for a dark cycle immeadiately following the tranplant as not to shock the root system
