CFL grow turned to HPS, what should I expect

[nseddy]

Hey all,
Im growing my jack herer, and i'm exactly 10 days into flowering today.. My plant is getting lots of pistils and seems to be doing great. Until now it has been a straight CFL grow because of the limitations of my grow box. i recently however built a new grow box approx 5ft tall and with it bought a 400w hps light just because of the praise they get in the forums. Will putting this light in now have any effect on my plants, or should i expect them to flourish under it in their last 7 weeks?

Thanks
