15 calculators to help you grow

The Greenhouse Growers Toolbox App, developed by Graeme Smith Consulting, is a suite of 15 calculators. The company is pleased to advise of an update to their Greenhouse Growers Toolbox App that is now available in both IOS and Android versions. "This updated app is intended to be an industry resource to meet the needs of growers, researchers, hobbyists, trainers, retailers, suppliers, advisors, etc. in the wider area of protected cropping (greenhouses, vertical farms, aquaponics, hydroponics, and soilless culture)," says Graeme.

This is the third release of this app from Graeme Smith Consulting, and it is planned to continue to make available additional calculators in the future. 

The complete Greenhouse Growers Toolbox App includes 15 calculators and is available for under 5 USD. 

Greenhouse Acid or Product Dosing
Calculate treatment PPM or volume (liters) 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 Hydronic Boiler Calculations
Estimate minimum required greenhouse boiler size (in kW & MCal/hr)
Greenhouse Dripper Timing and Volume
Calculate greenhouse irrigation flows, rates & volumes (media-based dripper systems only!)
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
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).
Air Filled Porosity (AFP) Calculations
- calculate approx growing media water content for pots/containers in %, based on the weight in grams
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).
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).
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.

The App can be downloaded from the Google Play Store  for an Android version or from the Apple Store for an IOS version
