so how long do a 400watts hps last 12/12 for about 8 month now.

I'd say good for 1 year.

Bro You the answer man .. You ever type more than one sentence ? I passed out at least 5 reps and still cant get you damn whats up with that ?

I'm a man of few words....

You get a "daily allowance" of rep love......use it all up daily..(if ya can)....then a few days later....it should let you rep me.......

What I meant to say is ...... The bulb may last for 2 or 3 or 4 years......but it's "effectiveness" goes down after about a year.......
I change mine yearly.....

31 words Manny ..YOU GO BOY .. Let all that knowledge flow ... Flood us with what your holding in.... Much Love brother

Welcome.......................................



*** *&$#%@#$ Manny... he's a virtual encyclopedia.... & quite as a monk

I agree, manny share what you know with us!

Tom
