G/W/M Grams /watts/month
1000 watt bulb in 2 months produces 1000 grams Thats if you real good at it. I only got 4.86 average
I would say you would need a clone of 60 plants in a grow room with 6 banks of 4 bulb (4ft)
With a grow room with 2 1000 mh bulbs ,using hydro buckets 5 gallon and a 100 gallon supply tank.
Thats with a 60 day bloom type, plus given a 3 day turn around time. To pull , cut, hang , clean buckets, bleach buckets. Than put in pre sized of 30 in ready to bloom from the grow room.
Note you will be trimming for about 46-50 man hours.
Thats just a close guess.
Please note g/w/m is a standard to gauge you output of the light, and system. Note Tic on over grow has gotten 0.6 grams per watt average with a scrog system.
My system is automated with a average 63 day turn around. :thumbsup:
