Who This Is For
- Small scale growers who find manual daily watering cycles too time consuming to maintain during busy work weeks.
- Operators using a VGrow Smart Grow Box who need a native automation solution to manage moisture levels via an app.
What We Found
- The USB power interface makes this unit easy to run off a standard power bank during short power outages.
- The black tubing is thick enough that we saw zero light penetration, which effectively stops internal biofilm growth.
What Users Say
- Users who integrated the app control say they stopped worrying about plant hydration while traveling for work.
- Growers switching from manual cans say the drip emitters provide a slow soak that prevents messy tray overflows.
