utilized locally in places where traditional farming cannot, like cities, deserts, and
even Mars. I hope that we as a society consider all the options we have available
to ensure food and water system security and equity for all people. There has
been some pushback about whether or not hydroponics and aquaponics can
be organic. I realize field-grown producers are not excited about having
more competition in the organic market, but we have a world to feed and
if all organic inputs are used to grow a crop, it’s organic to me.
Soilless cultivators face a plethora of choices when deciding which
growing medium is right for them, and many of these choices
can be boiled down to water retention issues. Judging by the
advice of Millar, a good starting point in understanding
how the water retention of a soilless medium impacts
plant growth is to consider both the environment and
container size as those two factors directly in fluence
the performance of any substrate. Also, different
plant species and phenotypes react differently to
wet and dry root zones. All things considered,
it seems that soilless horticulturists must
account for all these unique operational
factors when understanding exactly
how water retention effects overall
garden performance.
