Will my growing medium wick water itself
I am constructing an SWC, and have only been introduced to the entire world of container gardening about 5 days ago. Please bear with me.
This is a picture of what I would like to use as my reservoir. I would be placing 16 cut bottles upside down on the bottom of my SWC (don't worry about wood rotting and leaks, I have taken care of that). I am planning on packing the soil mix down in between each bottle, resulting in the soil acting as the wick.
The woman in this video talks about using the soil mix as a wick. (Go to 2:25)
Will this work? IF it does, I am afraid that there will be too many columns of soil mix in the reservoir (consider 16 bottles, there are 9 columns inside the square and then the border gaps that will be packed with soil mix). I am afraid that if there is too much wicking via all the columns, I will cause root rot. Please give me all your opinions. If I didn't paint a clear enough picture, please let me know. I am trying to learn as much as possible, and appreciate all your help!
