I have no insight why the roots in the buckets seem happier than the ones in the pots. Perhaps an oxygen exchange-balance thing, or an inherent need to go deep for nutes before it's competitors do, (in the wild) but I don't know.

There are three primary functions of roots:
1) to anchor the plant to a substrate
2) to absorb water and dissolved minerals, and
3) to store food reserves.
Info about roots

But there are specialty roots and membranes. All need water to dissolve the minerals, nutrients and/or gasses (air) in the soil it's in contact with.
Rusty Trichome Reviewed by Rusty Trichome on . Pot size/ shape how deep do mj roots need to be to be stable when grown in soil? Example: To use a pot that was wider than the depth to save space, will the roots grow horizontal once they hit the bottom, does anyone have any ideas if it would work just as well as a normal 3-7gal pot Rating: 5
