"How
to produce seedlings" (Maxim
um
Yield)
Compared to cuttings, seeds are relatively
quick to plant and are less likely to carry pests and disease...
"pH Meter Maintenance" (Maximum Yield)
pH
meters employing a glass electrode are useful for precise pH measurement
but require frequent calibration, proper storage and handling to ensure
accuracy and reliability...
"Dosing
Procedures" (Maximum Yield)
Nutrient performance is far more complex than simply using a quality
brand. Although growers typically blame the nutrient for poor plant
performance, the failure to follow basic dosing procedures is the cause of
many problems...
"System
Maintenance" (Urban Garden Magazine)
This article discusses aspects of how to maximize growth. This is
achieved by preventing diseases and pests, maintaining the nutrient’s
balance, and preventing the buildup of nuisance and harmful salts...
"Post
harvest cleanup" (Maximum Yield)
Do not underestimate the need for post-harvest clean-up. Failure to do
this properly can result in neverending disease problems, plumbing
blockages, broken pumps, etc. Two separate procedures are required...
"pH
of raw water is meaningless!" (Maximum Yield)
It is not uncommon to have two different samples of water of equal pH
where one requires four times more pH adjustment than the other. This
phenomenon is due to the concentrations of bicarbonate and carbon dioxide
present in the water...
"Conductivity
in Hydroponics (Part I): Monitor, Record, Adjust" (Maximum Yield)
Because hydroponic nutrient mixtures are usually composed completely of
salts, their approximate concentrations can be determined via conductivity
values. However, because each individual nutrient has its own specific
conductivity value, and the concentration ratios between nutrients are
continuously changing, conductivity readings need careful
interpretation...
"Using
Conductivity to Control Nutrient Concentration" (Maximum
Yield)
It
is important to control the concentration of your nutrients. Burning of
roots or foliage can occur if the level is too high. If the concentration
is too low then deficiency symptoms will occur...
"Nutrient
Management" (Maximum Yield)
In
addition to following proper dosing guidelines and controlling pH, EC,
etc., it is important to control the nutrient’s environment...
"Feed
Circuits" (Maximum Yield)
A
well designed feed circuit will ensure all roots are fed and flushed, and
not interrupted by blockages. Aim to make the feed circuit tidy and
uncomplicated. To minimize the risk of leaks and blockages avoid junctions
and restrictive feed
outlets (e.g. drippers) and always use filters...
"pH
Management for Optimal Results" (Maximum Yield)
This article explains how to keep the “pH” of
nutrient solutions between 5.0 and 6.5. This helps make sure all nutrients
are available for root up-take, and minimizes the risk of plumbing
blockages...
