Lighting and Vent Advice For Growtent

[Clint Eastwood]

Hi everyone my NL seeds from nirvana have arrived so i can finally stop worrying and order my gear.

Ive decided on a 1.2mx1.2mx2m indoor elements grow tent but am unsure about which lights and vent methods to use to avoid heating issues. This will be my first grow so i dont want something thats too hard to manage but i will go the extra distance if it means a big difference in yeild.

Should i go for a 600w or a 1000w hps? And would 2x 150mm ezi inline fans (blowing in at the bottom and sucking out at the top) be enough?
Or should i go for vented cool tubes with 3x fans (One in the vent and 2 others in the tent )?

I dont want to burn my house down or fry my plants so any help is appreciated

Always go for more light (the 1K, obviously).

Your exhaust fan should be larger than your intake fan in order to create negative air pressure - I have the same size tent and have a 170CFM for intake and a 435CFM (hooked up to a filter) for exhaust.

I also have a 435CFM dedicated to cooling the 1K light, which is essential - temps can build up in those tents very quickly when using large lights.

Take a look at my journal for details and pics of my setup.
