i have a new 400w digital ballast so i now can run Mh & Hps. so is it better to use the Mh 400w, 38,000 lumes in veg. or stay with the Hps 400w, 55,000 lums?? Mh, i know is better in veg but i'll be lossing 17,000 lums . So is it better to loss lums and gain correct light spectrum or just stay with the Hps 400w 55,000 lumes for the whole grow?? I was thinking about switching out the bulbs every day,,,one day Mh, one day Hps,, is this recamended, or is that a bad idea?? First grow pics below. below grow was Hps all the way from veg to now.
