New Grower No nute - pot size?

[Torched]

Quick question I have not found an answer to in my reading. I'm thinking about subcools super soil style, water-only grow. What is the smallest pot you could do that in. Is there enough nutrients packed into a 2-3 gallon pot to see most auto's all the way through? Or do you need large 7-8 gal pots?

I realize the size of the plant and harvest would be affected by the size of the pot but would you still get a decent harvest off the smaller pots?

A MJ plant need 1g per 4 weeks so in theory you could pull a 10 week grow in a 10-12l if you do not leach the nutrient but you would yield more with some bloom nutes or a slow release flower amendment nutrient such as bloom rock guano

A gallon per month sounds easy enough to remember thanks!
