Greenhouse Growers Toolbox 4+

The Greenhouse Growers Toolbox was developed for commercial & hobby greenhouse or hydroponic growers for everyday system design or management use.

The complete Greenhouse Growers Toolbox App is a suite of 14 calculators that include;

Greenhouse 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


Greenhouse Boiler Fuel Cost
Calculate and compare costs of various common greenhouse boiler fuels ($ per GigaJoule of energy)


Greenhouse Dripper Timing and Volume
Calculate greenhouse irrigation flows, rates & volumes (media-based dripper systems only!)


Greenhouse Hydronic Boiler Calculations
Estimate minimum required greenhouse boiler size (in kW & MCal/hr)


Greenhouse Irrigation Pump Capacity
Calculate required greenhouse irrigation pump capacity & maximum number of solenoid valves (media-based dripper systems only!)


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


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).


- 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).


- Calculate how often (in minutes) you need to irrigate based on current radiation intensity (and reverse).


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 (in mS/cm)


Common Elemental Conversions
Converts common elements to/from pure form (PPM only!) and lists common atomic weights
