if i were you instead of using mh to veg and hps to flower unless financial hardship ect,, i would get the new mh eye hortilux blue!its got both mh and hps in it but more potent of each spectrums intensity by 17 to 24 percent above the standard of each rapped in one lamp so you can veg and flower in one lamp,its got more red and yellow than normal hps and more blue than standard mh ect,, we just bought one 400 w new ballast mh and hps combo hydrofarm setup with this eye hortilux blue mh one lamp and your plants will disregard the specrtum they dont need during veg or flower,im telling ya this lamp spectrum wise nothing touches it,i could go standard mh and hps but this is alot better look at the spectrum chart for this lamp you will be impressed, in one week weve got at least a foot of growth easy and no streching without alot of folage to follow it this lamp runsQuote:
