Perf room suggestions please

Got a perfect room bout the size of a cell...
L 330cm/130"
W 230cm/90.5"
H 193cm/78"
I would like to save walking room infront of the tent also


I was planning on making a homemade tent to control the grow... i got some experience on a bit larger scale then this with no tent... pretty much watch-learn type deal with 1000W x10 and i was babysitting...

i am just trying to find out what kind of lights i should use for this size room.. HPS or LED(i like the procyon100).... i can ventilate but i would also like to know how to keep that LOW KEY w/ most yield...

I dont particularly want to use more then 300-400W as i know there are smart meters for power... i was aiming for 200w with 2 procyons.
i have an ass load of seeds Sensi star and darkie dark. so i can experiement slightly

Do not use LED, your yield will be very disappointing
Use HPS

are you an LED user or do you have physical evidence of this? i have had displeasing moments with HPS too... i am open to more detailed explanations as to what type of lights so i use less energy with max yield. please be more helpful!!! thanks

I use HPS and the yields they put out cannot be replicated by LED
You can waste your 600 dollars on that light but 1 400 watt HPS will outperform for a third of the price

its not neccessarily about the cost of lights... that is in mind but i am more concerned of the energy i am using. any tips on certain HPS or mh? how many u think i should use for bout 6-8 babies? and maybe subs for the flowering?
