However, personal preference and subjectivity
rules the day. A lot of the time it's like asking what's
better? Red or white wine? Bitter or lager? It depends
apparently on what you're eating with your drink! Well
if you believe that then you'll believe anything. Hydroponics
is the same. If you find a nutrient you like and you believe
it performs well then stick with it. If you are unhappy
with your results then experiment with another make or
a combination of makes and products; you've got nothing
to lose.
Hydroponics nutrients are a very important part of the
hydroponic growing process. Generally speaking, there
are grow nutrients (for young plants and vegetative growth)
and bloom nutrients (flowering and fruiting).
While it is true that plant "foods"
for soil are not suitable for hydroponics, it is quite
possible to use hydroponic solutions for soil growing.
You can actually achieve great improvements this way because
the plant is fully supplied as it may not have been before.
