Sorry, if you want to grow big then stick them in the ground. I just watched a youtube video from Austrailia where a guy had growing a 35 foot Thai plant. No plastic pot involved. He said it was just going into flower. Guessed it would flower for 4 months. Let's see, 35 feet probably 10 foot across, how many grams is that?
My guess it 6 to 12 lbs.
