The Greenhouse Growers Toolbox was developed for commercial and hobby greenhouse or hydroponic growers for everyday system design or management use.
The complete app is a suite of 15 calculators:
|
1. Greenhouse Acid or Product Dosing Calculate treatment PPM or volume (litres) of various products/acids when added to water |
2. Greenhouse Area and Volume Calculate area (m²) or volume (m³) of greenhouse structures
|
3. Greenhouse Boiler Fuel Cost Calculate and compare costs of various common greenhouse boiler fuels ($ per GigaJoule of energy)
|
|
4. Greenhouse Dripper Timing and Volume Calculate greenhouse irrigation flows, rates & volumes (media-based dripper systems only!)
|
5. Greenhouse Hydronic Boiler Calculations Estimate minimum required greenhouse boiler size (in kW & MCal/hr)
|
6. Greenhouse Irrigation Pump Capacity Calculate required greenhouse irrigation pump capacity and maximum number of solenoid valves (media-based dripper systems only!)
|
|
7. Greenhouse 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
|
8. Irrigation Timings per J/cm2 Calculations Calculate how often (in minutes) you need to irrigate based on current radiation intensity (in W/m2 and reverse)
|
9. Air Filled Porosity (AFP) calculations Calculate approx growing media water content for pots/containers in %, based on weight in grams
|
|
10. Greenhouse Radiation & Light Units Compare and convert common light (radiation) units used in greenhouse horticulture (inc. kLux, W/m2, J/cm2/h and mol/m2/h)
|
11. Assimilation Lighting & DLI Calculations Convert and sum common light (radiation) units used in greenhouse and indoor horticulture: PPFD - DLI - Radiation Sum - Total DLI, & reverse! (n.b. allows for both additional sunlight and/or artificial lighting if desired)
|
12. 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)
|
|
13. 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
|
14. 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 (in mS/cm)
|
15. Common Elemental Conversions Converts common elements to/from pure form (PPM only!) and lists common atomic weights
|
