time to veg

hey all, ive just moved my girls into veg i have 35 clones of alaskan ice, i was wondering bout temps and humidity, at the moment the room is 50-60% humid ive got a humidifier in there set to 55% i have a 4 inch exhaust running just to bring a little fresh air in with a fan blowing over them all my temp are 20 on lights out and no higher than 25 when lights are on ive got a 400w metal halide and a 600w growlux bulb on aswell does this seem fine? really cant afford to fuck up so do i need to tweek it at all? thanks hope some1 can chime in

!000 watts seems like a lot of heat for babies. They must be spread out though so maybe you need that much. But maybe just keep the 400 m/h over them for a little while since it is mostly blue spectrum better for the veg while the 600 hps is orange and reddish better for flower. But i have always liked my humidity to be as high as possible maybe 60-70%. That is hard to obtain though. Your exhaust sounds like a sweet set up.
Good luck though man. Hope what i said maybe helps.

If you have the right exaust system and plenty of fan air movement they should be ok.has long has temp is kept stable this can be done with great success.keep you fans blowing up at the light keep the fan's off your plants if they are still tender and young.keep the fans mounted just under the light this will get rid of some of the height.the first sign of any stress then i would put them under the 400 watt metal halide
]this sounds like a nice grow up and you could yeiled some realy nice nugs.but i would go for some daylight flouresents to put your clones under this is called playing it safe once the roots have developed then put them under one light till they are a few inces then put them under both.but if you invested some more money in the tubeing that will run through your two lights sending fresh air through this will aid in keeping the air temp right.good luck sounds like a great grow

thanks appreciate both lots of input i have the fan on plants going to move it so it isnt blowing directly onto them sounds like im doing it right going to start a log very soon my strain is alaskin ice cant wait
