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
