Yeah that heat will get ya! on my first grow i started 8 and ended with 4 females and then one of them went herm. And on my last grow i still came out with a hermi! Fix the vents and keep em all cuz ya never know. I guess the herms in my case may be cuz im forced to use bag seed but i know the 400hps for veg doesnt help... Did you use the 400 for veg too? Thats a great ratio you got! :thumbsup: Whats your secret?
