That maybe true but time is also a big consideration when doing cceedingly long veg times. That 4month veg could be almost 2 harvests doing SOG.i hear people pull huge number's with600s doing scrog 1 plant's type of thing but just take's the patience to veg for 4 months
Ya I've seen the one plant huge yield setups(usually hydro scrog) but they take so much time in veg and are a lot of maintenance. It's better just to shove as many 40-50 day vegging plants as you can in, prune hard in mid-late veg to where you don't have many side or lower branches, maybe prune again once or twice in early flower and you will get well over what the one plant setups get in near the same space. Under two 600s in say a 6x5x7 high room once one somewhat masters their growing techniques and with the right strains(preferably clones of same strain) one can easily get the 1 gram per watt ratio. I'm near there and not only hope to get to that milestone but hope to go beyond it.i hear people pull huge number's with600s doing scrog 1 plant's type of thing but just take's the patience to veg for 4 months
HARSH.Country that you live in?
Do you know how much you pay per kwh of electricity?
What else are you using besides the 600w?
When I used a 600w with 55w fan, 45w fan, 221w dehumidifier, 80w tubular heater on 12/12 my bill went up about £45 around $65 but I pay £0.27p per kwh for most of my electricity around $0.45 per kwh.
