hm and hps problems overheat help pls !!

hey guys i have 3 baby plants 4 days old under a mh 250w i have a fan inside the grow room but the temp is werry high i was wondering can i switch directly to hps 250 and use it in the veg stage ? and then after 30 days to switch it 12/12 ? or i realy need to use for the veg the mh ?

Do you have your grow room ventilated? You need to exhaust the hot air, and bring cool air in somehow. The HPS is gonna put off a ton of heat too, so it's not gonna solve anything.

And to answer your question, Yes, you can veg with HPS, you do not NEED mh, it's just preferred.

you can do it anyway you please your grow try and throw a fan in there to atleast get some air moving and invest in some ventilation

also imo 4 days old is a little young to be under hids if thats your only option i would back it away as much as possible

the lamps is like 50 cm away from the plants and i have a fan inside but the temp is still high and i think they have heat stress beacuse they are like bending
