How does this sound for my first time growing??

Im new to growing but I have done lots of research lately all about growing. here is the information ive gathered and would like someone experienced to look this other to critque what could be changed for my list of what I will all need.

im making a growroom 2.5ftx2ftx6ft. Im using panda skin to cover the side walls of my grow room (should i use panda on the top panel as well?)

-2-3 sativa clones
-aeroponic system(or should i do an EBB&FLOW system?)
-400w HPS light with hood(will i need CFLs or will this one HPS light be enough for my space?)
-Advanced Nutrients (veg partAB,flower partAB)
-Ph tester
-Temp/Humidity meter

I am unsure about fans because of my small grow space so what would be some fans that people could recommend and where they would go in the growroom?


I know I have alot of questions here but anaswering any if not all would be alot of help. (dont direct me to broad info. pages either only answer here or a link that already answers my questions.)
Thanks in advance

400 hps is enuff for that space , i use a 250 in the same space "heat issues" your going to need some ph down and up , you will also need a small/medium sized fan for in your grow room it could be facing down towards the plants are facing up at them + your going to need a fan on your door to suck hot air out and u need an intake whole at the bottom of that door for the air to be pulled in also.

make sure to get a tds meter so you can make sure your ppm is on point and I would go with an ebb and flow but thats just my opinion
