Put germinated seeds in soil on monday afternoon. They are all up, but today I thought they looked like they were starting to stretch a little, so I moved the light (400w hps) down to about 1metre above. The temp in the room is 82 with the light on, but the soil is a fair bit warmer than it was before.
Does this sound ok??

I know hps isnt ideal for veg but Ive been told countless times that they are ok if your pretty much going straight into flowering soon after they sprout, which I am. In this case should the light be higher??

ok I have changed the 400w hps to a 250w hps, and lowered the light to 2 feet above the tops. The plants are on their 4th day. Is this likely to burn them?? There's another 5 hours of darkness before the light comes back on so If anyone has any feed back before then that would be great.
