them are about 5inches tall
THX

yes. i vegged under my 1000hps all the time. just start high and lower it daily so ur plants get a chance to harden and dont burn all to shit. start about two + feet then lower it after a day of veg or so. but remember to check the heat with the back of ur hand to make sure its not to close. top of ur hand should feel lightly warm.

Shouldn't be a problem, you will have to raise in the beggining about 3-4 ft.
