The GroLog from Grodan is an app that assists growers in effectively managing their gardens. Keeping a detailed garden log is vitally important to a successful crop and with the GroLog it has never been easier to keep your garden dialed in!

Do you have several gardens you need to track at the same time? No problem - simply create a separate ‘grow’ for each of your gardens. The GroLog allows you to select exactly what data you would like to monitor in each grow, such as:
-Nutrient Solution: pH, Parts per Million (ppm), Electrical Conductivity, Temperature, Runoff levels, and Nutrient Dosages
-Room Conditions: Temperature (single readings or High/Low readings), Temperature Differential (DIF), Humidity (single readings or High/Low readings), CO2 (ppm), Plant Height, Irrigation Volume, Media Water Content Percentage.
-Lighting settings
-Daily photos and notes

The GroLog also enables you to set a gardening schedule and receive reminders for tasks you need to complete in the garden. Simply plan out your watering, transplanting, seed starting, or any other tasks and your device will alert you when it’s time to get to work, even if you aren’t in the GroLog app at the time.

Other features include:
-Customizable graphs that show you your ideal levels
-Comprehensive reports (pdf’s or spreadsheets) that can be e-mailed or printed directly from the app
-Photo gallery

Note: Grodan neither obtains nor shares any information, data, or pictures entered in this application.

If you’re serious about your garden…you need the GroLog!

Ratings and Reviews



I ran a hydro store for years and was always on the lookout for someone to make an app like this! Just the right amount of detailed info to track without overwhelming you. Other apps only allow you to track one grow at a time and don't let you email or print you're results like this one. So stoked about this, thank you thank you thank you! :)

Beautiful app with room to grow!


Nice looking app. I like the PDF/csv export and the many variables to track. One thing I would like to see is the ability to add custom items to track/graph. I see that you can add custom nutes in oz/tsp/etc, but there aren't graphs for these. I would also like to add custom measurements (e.g. Instead of just nutrient ppm I would like to add Ammonia, Nitrite, Nitrate, Phosphate, and dissolved O2 ppms). Otherwise, a handy app. This might just replace my lab notebook.

Just what I wanted


This is a great app I've always wanted to be able to log it easily on my phone. No more just writing everything down on paper
