    22 liters of water per day, per plant

That is about 5 gallons. That is not a realistic estimate for water usage for cannabis growing for its flower. I have grown cannabis for that.

That is a wild over-estimate.

Yeah dwc is about the fastest I've ever seen plants go through water and it was still only about 15 gallons a week for a couple of plants. Most of the time more like 5 gallons every 5-10 days. 5 gallons a day is pretty rediculous.

That does seem ridiculous. Right along the lines of the old media reports of pot busts in which law enforcement would claim to have seized a potential $20k of marijuana, when in fact they had grabbed like 7 spindly plants from some poor saps personal grow.

Hahahaha, him and his whole 10 grams. It's just all fairly silly.

I guess it could be true for an outdoor grow with monster plants. Indoor gardens are more water efficient because you're only watering the soil used by the plant and the plants are usually shorter.

Hydro is even more efficient because you keep all of the water in a reservoir lol. But still the fastest water drinking plants I've ever seen were going through about 15 gallons a week, and only for a couple of weeks at the end of flowering. Not realistic for most grows.

And one plant can yield many, many grams.

So, if we are supposed to stop "demonizing" the 1 almond == 1 gallon of water, cannabis gets a by as well.

Yeah, outdoor possibility probably 2000 grams for 100 gallons of water pretty easily over plant cycle. So definitely a better turnover than almonds.
