It is just an estimate based on the average watts of lights provided during both vegative and budding. It is ludicrous to base the cost merely upon budding wattages or to not take time into account. If the plants are receiving 1000 watts for 8 weeks and 600 watts for 4 then its ((1000 * 8+(600 * 4))/(8+4) = 867 watts. Cloning/seedling cost is just a minor given. That means you hope for a yield of 867 grams. Or 867 grams / Or 1 gram per watt. That is an obtainable goal even without using CO2 for most growers.
Some growers actually shoot for one gram per kWh used for lighting to produce the crop. Given the above times ((1000 watts * 8 weeks * 7days/week * 12 hr/day) + (600 watts * 4 weeks * 7days/week * 16 hr/day)) = 940 kWh. This would mean with say a SOG grow at four plants per square foot with 60 watts per square foot at budding, would have to each produce ((940 grams /(1000 watts)/(60 watts/sq ft)*(4 plants/sq foot))= 14.1 grams. Not far fetched. Half an ounce per each SOG plant. If that can not be done then you should not be growing pot. As the lighting is only about half the cost. Meaning (2*940) *$0.25/kWh = $470 for 940 grams. At a value of $15/gram that is (940 * 15) = $14,100 so ($14100/$470)= 30 Thats the ticket a 30X return on your money minus depreciation on your capital investment etc. Say 5 crops per year minimum. ((5 * $14100)-(5 * $470) - ($5000 capital investment)= $63,150 for a single small 600 watt veg room of say 10 square feet with budding under just 1000 watts of light in a single small area of 20 square feet. Now that is good valuable real estate. And people ask if CO2 is worth the cost????
