dude its like you have sen my grow setup and actually liked it ,then you went to redo it and made it better. seriosly i have the same fan ,the same light fixtures and the same setup. well allmost. mine is in a closet and the fan is on the side i have a clothes rack like three foot off the groung that four 27w bulbs dangle from and on two sides i have 42w bulbs in goose neck lamp fixtures. you have stronger wattage than me but i believe you are still having my problems. since your grow is not inclose even more so than mine you lose alot of light. cfls cast light in 360 and your hoods do help but mylar or white painted boards to inclose and box in your grow would really utilize your lumens better. i have way less light than you for now and twice the amount of plants but everything is peachy so far. i will be upgrading lights soon!
