I was thinking about doing that myself, but after looking at one plant in a 5 gallon bucket i dont think its worth the trouble of growing 3 in the same bucket. After all they might get crowded, have limited space to grow in (1.67 gallons a plant) not very much, might get you 3 ft at most, depending if you can get sufficent light to all the plant. Might be more work, than your willing to put in. My answer is no, lol.
