That's all good information. I wonder if the smaller pots give you less room for error? That would be my guess and makes sense from what you are saying - so long as you dial it in properly and run a tight grow it is doable. Seems you would leave yourself vulnerable to pH issues and salt buildup. I saw a thread where a few growers challenged to see who could grow the most weight in a 16" party cup. As I recall the winner pulled out a bit more than an ounce. I'll be watching.
