Sustee Aquameter Review | Myrtle & Mist
The reviewer highlights that the Sustee Aquameter offers a unique, passive, and permanent moisture indicator that is ideal for glancing at plant collections. While it lacks the graduated 1-10 numerical scale of probe-style meters, it excels as a no-action-required, glanceable tool that avoids the need to repeatedly disturb root systems. It is noted that the cotton core is a consumable item that requires periodic replacement.

The review identifies the Sustee as an excellent tool for single specimen plants due to its always-on functionality and lack of user error. It is noted that while the device is effective, it has ongoing consumable costs for core replacements, is limited to a single fixed depth, and may be unreliable in very coarse bark mixes or LECA.
