upon a second reading, my post doesn't read as straightforward as I had hoped. :P
Basically what I'm trying to ask is "if I put my one-week old seedlings, which have only been exposed to flurorescent lighting thus far, under a 400 watt HPS, will they be able to handle it or should I wait?". Maybe they're too young and won't be able to survive under the intense light--that's my concern.
