So many different systems. They all work great. I was using earth box setup before i moved to auto-pot xxl. Ill give you my thoughts. Keep in mind i grow with dry amendments.
I personally liked the earth box better. The fresh water reservoir for the roots to have access to is game changing. The plants will build feed roots where the top dress is and drink clean water below. Let the reservoir run out and then you just fill it back up. Its easy!
The con: One down side is during flower the reservoir could only last about 2 days minimum during peak stretch. This isn’t a problem for when you are available. But, life happens. Vacation or weekend trip or whatever. It could dry out. Thats where auto-pot system can be a difference.
Auto-pot pro: is the large reservoir that fills the bottom container that bottom waters the grow container. Its nice because i can leave for a week and the plant wont run out of water. And you can have as many plants you want on that reservoir if you have the base and tube to connect it. The system is proven to work.
Con: its expensive! I have mixed feelings on keeping the bottom consistently being waterlogged. Which is part of the wicking function to bring the moisture up.
(Personal feeling) i just think i prefer the earth box style instead. Only part of it is submerged into the water for the wicking and the rest is open acces for the roots to drop down for air and drink freely. The auto-pot is less hands on and had scalability. Which is why i bought it. It works great. But, if i had to pick a favorite… Earthbox.
Now, i didn’t know about the octopot until after. the more i see how it works the more i like. It gives me that hybrid auto-pot/earthbox vibe. The best of both if it can auto fill. But ive never tried it. So, i dunno…
