Smallest pot size ?

[Tommytopper]

As the title says what’s the smallest pot size people have used pure coco and still got the results they wanted 

 

I’m planning on running 9 plants in a 5x5 1000w de hps 

 

I like the idea of multiple daily feeds so a smaller pot would be ideal I’m planning on vegging for 2/3 weeks once transplanted from 0.7 litre pots from seed

 

 

thanks

I wouldn't go smaller than 7.5litres, that gives you the nightoff/day away comfort zone, even if the sun has been out, and any irrigation failures.
