until it needs more. A top up can be done if
you do not want to change the reservoir
totally. If you do not have a PPM meter to
calculate this accurately, simply write down
your nutrients mix ratio from day 1. Let’s say
we used 3.5 ml of A and B and C in a 1 litre
drum. Now the plant has drunk 1/2 a litre, now
all you need to do is make another litre of
3.5ml mix in another container and add 1/2 of
it to the reservoir. This is one simple way of
doing it, but you are left with a half litre of
solution, so do your math and make a mixing
chart so you can mix up different amounts as
needed. Local grow shops will help you most of
the time with any questions that you might have
about their products.
CANNABIS AND HYDROPONICS
Growing in hydroponics is not rocket
science. It is a simple process which can vary
from system to system depending on what kind of
a set-up you choose. Most of the nutrient mixes
are explained extremely well on the packs. If
you follow their instructions and remember that
Cannabis only needs 30%-50% strength nutrients
then you will do just fine.
