i actually forget what strain that was it was so long ago.Now i grow east coast sour diesel,legends ultimate indica,white diesel,and i'm just starting big budxnl.Well i run 6-8 1000 watt hps lights pending on the time of the year and the heat issues i have to deal with.My split air unit will only maintain temp on 6 lights during the summer like july aug.so thats when i do six.i usually veg for ten days with co2 in 1 gal pots.At the ten day mark i transplant into seven gal pots and veg for another 5 days or so just so the root system has a chance to fill the space before the switch too floweri used to do six plants per 1000 watt hps light,but i found that while using my light meter that i had almost as strong of lumens outside the four foot candle pattern so i bumped it up too 9 plants in 7 gal containers per light.i have grown the same strains for along time and i usually average the same yeild.Which has been consistent with about 1.75lbs to 2lbs pending on the strain per light.After switching to 9 plants per light i just finished at 2.3lbs per light.My electric bill is about 600-650 per month,but i run 8 1000's and a 12 inch can fan on a can fan carbon filter.2 6 inch vortex fans to cool my hoods.An 8 inch vortex fan for fresh air.Two different cap controlers a co2 controler,two oselating fans and a split air unitThis next grow i'm using bio canna which i've been told by many has increased yields by up too 30% over bio bizz.I'm also gonna be growing in bio canna terra cocco medium.Its suposed to be the shit we shall see it better as i just spend 1850 bucks on medium and nutes to do an 8 lighter.I would imagine.Pending on what they charge for electricity where u live will vary,but my bill goes up like 45-50 bucks a month per light.
