Hey Ozdia,Also running them in 3gal (11L) square pots just wondering what length do you recommend having the drip line at. Having a few issues and going to pull them and reset them following your steps.
Here's a pic of my 3gal smartpots with Blumats in action.
While the length of the drip line is important (radial wicking) what's even more important, especially in smart pots, is the distance of the back of the carrot to the container wall.
If it's not big enough or the soil is fluffy, the blumat will be triggered by drying out from the back!
I try to push down extra soil behind the carrot and compact it a bit so it will not easily dry out.
No snorkel tek here, just some top dressed guano under the drip point.
Hope you enjoy yours mate!
