Dunno about temps or humidity to be honest.The light is 2 feet from the plants... Now also my Humidity is around 60% is that good?? and temp is 29
I grow in a cupboard and swing the door back and forth for ventilation and use a disposable dehumidifier during flowering to stop mould.
I have my hps 12" from my plants when flowering.
I notice that your fan has speed settings so lower the hps to 12" above and adjust the speed of the fan until you are happy with it.
It might be a good idea to lower it by 3" a day at first and get the tops used to being warmer.
Obviously with the light nearer and the fan on faster you will need to keep a closer eye on them as if they grow to fast they may get tip burn and they will dry out more quickly.
I have my hps 36" away for baby seedlings and i have been lowering it by an inch or so a day.
As soon as i go to flower it will be lowered to 12".
Watch out for hot spots and keep an eye on them and all will be fine.
If you cant keep a regular eye on them i wouldn't recommend 12" away in case they have a growth spurt and get burnt
