>>92092I dunno ... I was trying to make that bucket based on like this
http://www.insideurbangreen.org/diy-sub-irrigation/I don't even know how it worked lol
I am just want to knew if I was doing the right step or not
Previously I use version using 2 buckets... but one bucket is more convinient...
All thing left is put the dirt and the seed later... this is only the setup
