The world’s population would quit growing so rapidly if we quit feeding the middle east. If they’re gonna make all the babies they should have to feed them.
so....the way they’re claiming ‘no fertilizer’ is to call it “nutrient-rich water”. got it. Cute. but oh, so, misleading.
four most common problems with hydro verticals: bacteria, algae, black mold, and the enormous energy cost equally lighting the entire height of the planting for 18 hrs/day.
Then there’s the equipment: man-lifts to get to the top, constant pruning to keep one main vine on tomatoes, hand-pollination since no bugs (bees) will make it inside. (If bugs do make it inside, dollar to donuts there’ll be hornworms or the arab equivalent and those will have to be hand-picked off). Not to mention the leaching over time of pvc and assorted poly tubing exposed to acidic ‘nutrients’. And then there’s all that ventilation equipment - the hothouse will be both hot and very humid (the discharge of which will create its own local microclimate), bordering on human heat tolerance for workers and impacting mechanical tolerances for moisture and heat.
Lots of challenges...let’s see what they do.
I mean there are pros to doing it this way.
The cons are loss of power, loss of water, fire in the structure damaging things. Infestations of things could still occur even indoors.
Planes fly seven or eight miles up, just how tall is this vertical farm?
