300 gallons is a small hole. My garden has 60 300 gallon
smart pots that were custom cut for me back in Feb...My additions next year will be in 12x12 mounds..FWIW..I actually have grown in a 300 gal
smart pot , and seen plants grown in the ground in a WAY larger mound than a
smart pot could ever dream to be...and with the soil being mounded ABOVE ground there is still air pruning happening to the roots etc.,, Don't get caught in the hype..just get out there and grow...FWIW>..the 12x12 mounds will be 2400 gallons ...Have fun in the 300s
PS>> It cost me $2800 for 72 custom made 300 gal
smart pots and I get them for wholesale! It would cost me way less in red dye to dig the holes with the KX121-3.
