Like this. Would probably work. Have holes drilled along it's length that you would water through. Then plug them with a cork or rubber stopper so light wouldn't get to any roots trying to grow out the holes. Cool.
Marc Benson Reviewed by Marc Benson on . STRESS LESS TRANSPLANTING UPDATE 48 hours later. Here is the exact same plant that was used in the demonstration. I had duct taped the clear bottom of the soda bottle / container. Upon removal and inspection of the rooting system, you can see how there is indeed STRESS LESS TRANSPLANTING when performed properly. This is 48 hours later and the rooting system has already taken control and the plant continued to grow and thrive almost instantly :) Rating: 5
