"Greenhouse Growers Toolbox” was developed for commercial & hobby greenhouse or hydroponic growers for everyday system design or management use. This is the Free lite Version of the Greenhouse Growers Toolbox, it includes 5 Calculators; - Acid or Product Dosing Calculate treatment PPM or volume (litres) of various products/acids when added to water - Greenhouse Area & Volume Calculate area (m²) or volume (m³) of greenhouse structures - Dripper Timing and Volume Calculate greenhouse irrigation flows, rates & volumes (media based dripper systems only!) - Greenhouse Radiation & Light Units Compare and convert common light (radiation) units used in greenhouse horticulture (inc. kLux, W/m2, J/cm2 and mol/m2/h) - Common Elemental Conversions Converts common elements to/from pure form (PPM only!) and lists common atomic weights The Complete App is a suite of 12 calculators that also includes; - Boiler Fuel Cost Calculate and compare costs of various greenhouse boiler fuels ($ per GigaJoule of energy) - Hydronic Boiler Calculations Estimate minimum required greenhouse boiler size (in kW and MCal/hr) - Irrigation Pump Capacity Calculate required greenhouse irrigation pump capacity & maximum number of solenoid valves (media based dripper systems only!) - Irrigation Rate Targets Calculate greenhouse irrigation volumes based on area, dripper rates and light sum, and compare to actual irrigation volume delivered over the same period - Greenhouse Nutrient Deficiency Chart Use the flowchart to determine in a systematic way which element/s may be causing deficiency symptoms in the leaves. (Includes typical examples of leaf deficiency) - Greenhouse Nutrient Feed Recipe Guidelines Standard feed recipe guidelines for both Open and Recirculation media based hydroponic systems (in PPM and mmol/µmol) and includes most common greenhouse vegetable crops - Greenhouse Nutrient Drain Reference Guidelines Enter laboratory analysis of your hydroponic drain water and compare to reference guidelines for your vegetable crop (in PPM and mmol/µmol) and includes automatic EC correction
