questions with no answers.. advice

i've started my new indoor growbox and i've come to a little problem.. i have had a few previous grows both indoor and out but i just built a bigger box and i was wondering what to do. a little discription on my setup... i presently run a flowering box that has 15 top cfl's all of the warm white type. i have 3 cpu fans that run 24/7 1 inlet 1 exhaust and 1 in room circulation fan. the lights are on a reflector that moves on a chain and the walls are lined with reflective material. the dimensions of the box are 2'x2'x3'.

i want to upgrade to better light but i'm on a low budget my buddy is a contractor and he can get me 2 70w hps for little or nothing but they have no end chord (plug) how hard would it be to wire this up?.. is it any harder then adding a plug to a lamp? ... do i need a certain type of wire..? and as i said i have 16 cfl's now but if i add this would it be better to add these and sacrafice 8 or more cfl's to do? will it get me better harvest/buds? will the fans that i have now be enough air intake
and outtake to keep the room cool?

aslo for the 2 hps's can i take the outer part of them off so i can make more room for more lights...? seen i won't be exposeing those to water will i take them off or will it not be safe?

any comments or sudgestions are accepted

if you use the hps you will need ballast to if you dont have. have you turned on the cfl set up yet? seems like it`s going to get way to hot in there

a 70w hps has the ballist built in i think or either that it doesn't need one because one of my friends had one on his gro and he just uses the socket but his came pre wired

proly has the ballast and everything. Is dat wat you using cause heat is a real issue wit those.

yeah i think i am going to use those when i get them.. i have 3 fans already and i was going to add a 1'long 4" wide fan that circulates the air inside the room it has a low and a high setting .. would this be enough to cool the room with 8 cfl's and 2 -70watt hps?

i had a cab that was about 3x3x4 and 4 42 watt cfl`s plenty of air and venting and was way to hot. if it`s an hps you will need a ballast havn`t seen one yet that didn`t

well a 70 watt one has a built in ballist it's a security light such as the one below

ya it`s all in there. i would recomend dismantling it and keeping the ballst set up outside the room, those get pretty hot. but try it first then if needed take it apart

sweet is putting a plug on those the same as putting a plug on anything else?

.................ya, use 3 wires, and i would have it go through a surge protected power bar.

yeah all my present lights go through one of those and i use an outdoor plug in it with a reset button on it
