Hey
I'm currently scrogging single plant in a 20L container about 5 gallon, its a clear plastic container, i put her in 2 weeks ago - her growth has exploded in those two weeks and i'm already seeing roots pushing up against the side, I reckon in another two to three weeks i'll be ready to flower her and I'm thinking of putting her into a 40L or 10G pot to flower, root system has a massive impact on bud development, and its not worth losing grams because your pot is to small!
