Always check your hydroponics pH level as
often as you can. pH can slip up and down very
quickly in hydroponics systems.
Alga:
Alga is part of a large group of non-
vascular mainly aquatic cryptogams capable of
photosynthesis.
Always keep your container away from
exposure to direct light, as alga will grow in
the container if you do not. This seems to be
something of a problem because we grow plants
under lights and we may have a system that has
to be sitting near the light so the plants can
grow properly. Most hydroponics systems have
been manufactured ‘light tight’ to eliminate
this problem. If you built your own system then
you may want to keep your solution sealed from
the light by using thick black PVC tape to
cover the lid and the entire reservoir. This
will help prevent alga from growing in your
system.
If you do have alga growth then you need to
clean your system out. Wash the unit and
replace the nutrient solution with a fresh mix.
