I have 3 mothers under a 250w hps right now theyre all about a month old but growing pretty slow... Would there be any disadvantage to putting my 1000 watter over them till they get bigger then putting them back under the 250watt?
250watts in a small area with good wall reflection should be fine to keep them going, but I'd suggest having that 1000watt up a bit higher from the tops than the 250watt.
