RE:Aurora to build a 1.2 million sf greehouse
I remember that they were looking into it's ability to actually produce another EXTRA crop each year, as the plants can grow faster using their water.
Here it is from their Corporate Presentation:
Highest indoor and outdoor CO2 foliar spray value is for cannabis growers. A 1M sq ft greenhouse growing 5 crops/yr. makes $120M/crop at $6/gram Indoor cannabis CO2 grow trials are proving one more $120M/yr. crop is possible. Outdoor trials for one crop/yr. are to grow plants larger and faster
If that is true, then they can produce an extra 6th crop at your $7/gram for a total of $270 million extra revenue**, not to mention a bigger profit margin (as their Co2 method costs a lot less than their current method).
**(assuming that Aurora would be growing five crops in their Aurora Sun facility using their current methods)
