Dude. Don't get it twisted; I'm NOT the boss. Those are your plants. NFT needs to be really well aerated, either with stones int eh res or by a waterfall/cascading action somewhere in the system- surface turbulence adds oxygen- and the film should not be too deep either.

Here's the cut n paste of the form... just open up the thread and copy it. Or copy it from here. Or whatev.


E-indoor or outdoor
E-soil, soilless, coco, aero, or hydroponic
E-specific medium
CSL-Soil type/brand
HCL-Hydro/aero/soilless system type
SCL-Anything you have added to the soil
SCLR-Soil or slab runoff pH
E-Water source
E-Source water pH
HRT-Source water EC (if hydro)
E-Age of plant
E-Type of fertilizer
E-Rate of application (if hydro, this is your PPM number, preferably after each component is added)
E-Lighting source and distance from plant
E-Air temperature (both day and night if you are running a dark period)
HD-Reservoir temperature
E-Air % Relative humidity
E-Lighting schedule
E-Type of ventilation your room has
TR-Did you pre-soak your media in pH corrected solution?

Can you also post a pic showing the whole system as it sits in the room?
