What if I told you that scientists ad NASA developed the most efficient hydroponics system to date, with a reduction of up to 98% water consumption and yields hundreds of percentages higher than traditional hydro systems?
You may have heard of Aeroponics in the past, but if not you are in for a treat! By misting or spraying the roots directly, this system is able to optimize plants' nutrition uptake and growth by leaprs and bounds. This kind of system, or something like it, is likely what will be used to sustain life on the Mars space station some day.
This is a perfect example of how Hydroponics is more than just a hobby- it is a science and an educational pursuit.
