Random Japanese Fact of the Day Prt.43
An indoor farm in Japan can produce crops 2.5 times faster than fields using LED lights, and it produces 10,000 heads of lettuce each day, where a traditional field produces around 26,000 heads a year.Japan has always been a land of innovation, but this is just from another world. A physiologist in Japan has transformed a semiconductor factory into the world’s largest indoor farm. For the ever-increasing food demand, this could be the best answer and a proven one. With the size of half of a football field, this isn’t just another indoor gimmick. Around the globe, millions of tons of food are wasted every year creating a shortage of food in many places. With this system of farming, more food can be produced in less time with less money. So, with this mode of farming, you wouldn’t require a lot of farmland, or pesticides as an indoor room is mostly pest free. The main motive of the thought behind this technology was to reduce organic waste at the source and increasing production in a cost-effective way. And with 10,000 heads of lettuce being produced every day, it is safe to say that they have succeeded to a certain extent.
Which isn't surprising given lettuce is already a pretty popular hydroponic product, and it's being grown in an urban farm. Idk how popular typical indoor farming is, aside from avoiding pesticides, I think most just opt for outdoor farming. It's cheaper in most cases.
Disclaimer: I am not a farmer. But I'm going to guess a couple reasons:
Space. Ironically this doesn't take up much space, but it is all indoors, most likely in an urban setting which is a bit harder to acquire space for, especially for such a low cost operation.
The crop. Lettuce is a popular hydroponic product. That means it doesn't require soil, just some light, some water, and some nutrients put into that water. Marijuana is another popular example of a hydroponic crop. This loops back to my disclaimer, but I don't know how many different kinds of crops you can really grow this way. For all I know, lettuce might be the future soylent (soylent green is people! or is it lettuce?).
Traditional farming is well established. This is probably the weakest reason, but traditional farms already kinda have a system down that works very well. Completely reworking the way your business works is not only wildly difficult, but extremely expensive as well. So even if it were possible to start growing grapes and making wine all inside a 10-story warehouse, it may not necessarily be easy to make happen.
Controlled greenhouse growing in Japan is big, and there is a lot of unused farm land now because of the aging population. If you're interested, the department of agriculture (農林省 Nōrin-shō) will help you get bank loans and hook you up with farmers that want to lease all or some of their land. Strawberries are big, as are melons. So if you want to move to Japan and start a farm, there you go...
