First Grow Advice

i have just bought a secret jardin grow tent(1.2x1.2x2) im just wondering what ventilation would be good and what light to use i was thinking a 400w diamond Lumatek Lighting System and a 5" fan to bring fresh air in and a 5" fan hooked up to a carbon filter to take air out. i will be growing organic style in soil and will this be sufficiant to grow about 6 plants any help would be great CHEERS

The diamond is strange. In a tent you probably want something air coolable. Then you would want a fan to cool your reflector and then another fan to get fresh air in the tent at the least. When fan shopping look at CFMs. the setup you describe will probably work as is depending on the temperature of the room the tent will be in. If it is warmer that you want your tent you definitely have problems. Good luck
