using the big 12/12 lights for vegg while they r on?

first of all, by no means am i a noob. im a second gen gardener and have been at it or around it most of my life. my dad likes to come on here and read and post on occasion as well. hes pretty stuck in his ways and is about as old school as it gets when it comes to evolving as tecnology,lights, nutes and everything else evolves around us weather we go with it or not...my question is: has anybody moved their vegging plants into the flower room while the lights r on to suck up the "most likely" bigger watt lights and then just place them back in the vegg room before the flower room lights shut off? surely the vegging plants should benifit from the bigger lights blasting them for at least a good 12hrs...i think. my only concern is it might shock the plant going from a 4000w room back to a few floros everyday. like i said, i dont kno but im curious if anybody does this or has done it and what were the results? im curious about this because every 6 weeks, i have a large ammount of space opened up in the flower room for about 4 weeks that my brain keeps telling me to use as long as i get them in another light source before the 12/12s turn off..any thoughts yall?

if you got to start your thread with "im not a noob" your probably a noob lol

your flower room should be full so you cant fit anymore from veg. in there.

a 400w mh for veg. should be sufficient and not have to put them under the hps lights.

@drolove
i had to start it that way cuz it sounds like a stupid question in my head but yet i want to know an answer to it. trust me bro, ive been at it for years...lol
@smoke and coke
i have a large flower room and like i said, every 4-6 weeks after a few r harvested, i have a good ammount of space availabe before the next round(s) get cycled in. just trying to utilize the light/space to my advantage without harming my ladies from swapping them from intense hps lights to sort floros...thats all.

im not looking for a big ass debate or looking to catch a bunch of flack, im just curious if anybody has tried it out and what were the results? its just that easy..lol
