I been using the auto pots system for over 3 years and love them,
I been experimenting on which medium is the best and nutes,
At the bottem of the pot I fill it with clay pebbles about 2-3inches and then just fill it with canna coco no need to add nothing to the coco, this is the best way in my opinion, just dont re use your coco as I had bad experience with
let me know if any one need some advice,
The only thing I wonder Sometimes is why isnt every grower using autopots
Auto pots have made 100%effort go to 10% in other words they made life much easier and my plants never can be better
