I made a little game with the lights at the 4th week of veggin. I swiched on 18/6, from 24h light, and every day i was changing the levels of the light distance, some times up and sometimes really close, in order to force the plant to some stretching and then normal again. That made the plants to grow narrow with many internodes very close to each other, with actually no stems, just growing tips. When I turned 12/12 they just gave all the power to the single stem go grow a big fat cola. That worked better with my oldest plant (with the big cola), but I cant say that i dont like the other one also

They r unknown strain of seeds i collected through the year.
