Smart pots and autoflower

Thinking about using 3 gal smart pots for my NL x LA Diva auto grow. Just wondering if anybody had any experience growing autos in these pots?

for smales autos need 7 liter pots a minimum, biggest pot it's biggest plant,more buds, the first one for autos are ground,soil,coco, and pots size,next one it's temperature and humidity with lights together.
after 1-2 years we all growing in hydroponic/ air pots and using plasma light
