1000 watts

i have a 600 and a 400 watt hps hortilux bulb in my grow room what is a reasonable amount that i should be able to get from that. i know experts can get like a gram per watt but i want a reasonable amount that i should be able to get with having proper nutes good ventilation etc

a lot more factors then just light come in to play...if all the elements are great in your room 100% of the time( which is hard) you should get at least a gram per watt...also the strain has a lot to do with your end product too....lots of factors my friend..

Many diff outcomes. At lease an oz or two. But we DNt know ur experience level or strian. It will get better with time. I mean if a noobie and vet took over the same grow the vets gonna pull more

My first 2 grows with a 400w.hps/ Each plant i got 2.5 oz.(dry) It was just bagseed. But if i base most of my math on those conservative #'s . I'm never disappointed
