What can i add to my growroom?

[sum0]

Ive got a Pc fan coming out of the growroom door and a normal fan blowing cool air onto the plant + a 400W HPS and some reflective material around the edges.

Depends. If it gets too hot you may need a better exhaust.
hot air is more easily removed from top and the hole in the door could be used for passive intake.
when flowering you may need to seal the light w/ a trap or wather stripping around the door seal.
Maybe some cfl's for side light or justfor blue light spectrum.

Wait, I see you have a plant growing. If nothing is wrong are you looking to justtrick it out and go all techy.

Do you have a way to measure the heat and humidity? Do you ph test?

nah i never got around to getting those. would they make a significant difference?

Heat can and will be your enemy.

with just 2 little pc fans, and a hps burnin so close to your plant, things could get purty hot in there. thermometers are quite cheap, stick one in there. xx

more plants

well there is not much else you can do for heat besides more vent, an ac is not practical for there nor do you need it, i would look at maybe carbon filters and circulation fans but first you need a ph tester, that my friend should be your best friend

yes, a HUGE difference. I don't have a pH meter and ever since i've been growing my plant, it has always been at an extreme- either too high/low. I stopped adding nutes because thats what does it. It has been about 6 weeks that I have been growing my plants for and it is still under veg because the growth was stunted due to ph variability. It looks like it is about 3 weeks old. I just found out the importance of the pH meter and it was through personal experience. your best bet is to get a digital ph reader which can be found for around $30 on amazon.
