These are excellent for all types of planters (potted house plants, 5-gallon tomato buckets, Garden Tower® systems, etc.) with a diameter of 3" or more. 

The Project staff has been using these moisture indicators for four years! We import them directly from their manufacturer in Japan because we love them (and there is no distributor markup)!  


Garden Tower user instructions: Insert indicators at a 45-degree angle pointing down.  Place one in the 2nd ring and one in the 4th ring.  You can place them on the same side or place them opposite of each other for more coverage of the system.  If your upper Sustee probe is drying out (white) before your lower probe, then decreases the watering volume and increase frequency. If the lower probe is drying more quickly than the top probe, you need to increase watering volume (for example, move from 4 gallons to 6 gallons per top watering session, twice per week).
