Grow tent size. and lighting.

Hey ya'll. so i got myself a grow tent size 80x80x160. and i'm about to grow 3-6 plants.
got to know how much watts of HPS/HM should i get. i was thinking about 400w. but a friend of mine told me 600w is much better.
so go with 400w or the 600w ?
ty

So about 3x3x5? 400w would be good, but 600 would be better. that being said, can you get rid of the heat? if heat is not a problem, go with 600.

a 600 watt light gives the best bang for the buck out of all of them. as dirt power said, get rid of the heat,cool tube or similar. I run 3 of them in my 6.5x6.5 tent and air cool all three. best lumen per dollar spent.

I'm thinking AIR cooled would be the way to go, I have cool tube because I jumped the gun before I knew all the pros and cons...not saying cool tube is bad or anything, but from what I think I now understand is that air cooled would be better. just saying.

Cool tubes are air cooled. I have a 400 watt hps in a cool tube with an extractor fan in a 24x48x60 tent and my temps stay 75- 78 degrees.

So 600watts will performe better? i'm about to place my order. how's Hortilux HPS\HM , any good?
and will a fan be fine by cooling my tent with a 600w ?

Gonna have to exhaust dude! a fan will be fine for air movement, but your gonna have to exhaust the heat! 600 will produce a LOT of heat!

Just to let you all know, I'm new to indoor growing...just not new to growing pot... this is a new ball game to me...very different rules so to speak.

I'm a farmer first and everything just fall's into place...being a farmer requires a little understanding of all this in the first place, just a few tweaks gets things right....but one thing I know for sure! is that, no matter how much you think you know...you will never know everything!!!!...thus the need for the forums, I still need to learn a LOT!

True, but air cooled and cool tube are just a little bit different in there make up, cool tube is just a tube around the light, air cooled has a glass lid covering the bottom of the reflector. Not sure if it really makes a difference or not, some say cool tube creates hot spots and that the air cooled doesn't...all I know is that I'm too new to indoor growing the know for sure ...yet!

I would go with the air cooled. I just replaced my cool tube with one and my tent is 5-8 degrees cooler.
