heres a general idea for others to get an idea..
2 months of growth at near 24 hours a day = 60 x 24 = metal halide total hours
1 month of budding at near 12 hours a day = 12 x 30 = high pressure sodium total hourly output
4 bulbs making 1 pound per bulb
total cost 4 bulbs plus 3 months power + equipment = $2000 /4 bulbs - 500 per pound to produce..
Now this is a bit odd evaluation but as a general evaluation its close.  |
Ok without totally explaining in public on how to do this I will answer a few parts of what you said. Though you are not explaining how many plants that each bulb covers.
Part 1. You do not need 2 months of the grow cycle, this can be cut down to a couple of weeks. Seriously you can go from clone to budding cycle with little growth. This also allows a great deal more plants per square foot.
Part 2. Yes 28 to 30 days for budding, 12 hours per day.
Part 3. 4 bulbs making 1 pound per bulb?
Numbers.
Average bulb life - Four months (flowering) Six months (grow)
Flower time - 28 to 30 days, 12 hour cycles.
Grow time - 14 days, 24 hours on.
Electricity rates - Commercial @ $0.0341 per kWh, state .0001 kWh, fed .00125 kWh. $.03545 per kWh total.
Bulb Cost - Bulk wholesale purchases only under a NPO organization. 1500W 21.00 mh, 19.00 1000w hps.
Yields - average 244 grams per square foot.
