light change

hi people iam wondering if anyone can tell me,ive just swapped bulbs from a 400 hps to a 250 enviro due to heat probs is there any difference in the growing time,they look alot healthier under the 250.iam gona swap back to the 400 for flowering as ive read this is better any help would be great cheers.

Yea, there's a difference in growing times. Usually fluoros are a bit slower than HID, unless the HID is too close.

well thanks for that i didnt think anyone was gona reply,i used the 250 enviro for bout a month and they didnt move went on a go slow,so now ive changed back to my 400 hps,next time will start them on the 250 and will swap for budding thanx mate.
