Grow 3, choose the best, get the biggest pot you can find, give that one girl the whole tent and let her amaze you. I have just finished growing 3 TD in a 120x60x150 tent and it was NOT easy. This strain produces plants that WANT to be big. As more and more people grow this strain and post journals I am seeing the same characteristics I encountered over and over. This is not some 30cm tall autoflower. In large pots, coco, DWC etc where the roots can thrive the plant will grow huge. If you try to flower more than one plant in that tent you will encounter the same problems I did, quite severe stretching as the plants compete with each other for the light. Grow one monster plant mate. I truly believe we are going to see a lot more 10 ounce+ TD's in the near future
