All ‘Pens’ measure EC ( Electrical conductivity) and convert to PPM=TDS ( Total dissolved solids)
– Gives a reading of how much salt and or matter is in the water.
-A reading should be taken of the water before adding Nutes.
microbiology in Nutes:
-All bodies of water posses Microbiology.
Organic hydro uses high levels of microbiology to decompose organic matter.
Aerobic bacteria require high levels of O2.
-Best achieved through moving water.(Water fall is best way to get O2 to dissolve in nute water.)
Warm water holds less dissolved o2 then cool water.
-temps best kept at 68-75 deg.
Air stones are only 5% effective.
beneficial bacteria and fungi are prevention to disease.
Imbalance= Plant stress, slimy brown rotting ro0ts.( Root rot)
Healthy= High O2 Nutes, beneficial bacteria, breeding, comp for nutes= HAPPY plants.
-CO2- Intake CO2 and exhale O2
-Natural air contains approx 2% CO2
-Measured in PPM ( Ideal 1000-1600 ppm)
-Can Purchase CO2 and regulator to release CO2 when levels dip.
-Some greenhouses operation use of CO2 from near by factories or resources.
-Co2 increases yield.
Down side. Increased Heat, possible CO2 failure choking plants.
17 essential plant Nutes.
PH adjust with balance of TDS
Defecienes of even 1 element can show.
microbiology plays a larger roll in prganics but is also helpful in synthetics.
Commercially avaliable Nutes easy and accurate.
Supplemental CO2 can play a roll.
