I know genes matter but generally how big will photo-period cannabis get when grown Outdoors in the tropics during months when daylight is less than 12 hrs

Hello. When I bought Lemon Skunk from Greenhouse Seeds a few years ago it came with a DVD of the Greenhouse crew in Jamaica. They interviewed a native Jamaican and he said that the light is 11.5 hours in the winter and 13 hours in the summer. This native said that the locals grow their plants inside with lights at 18/6 and put them outside when they feel they are big enough to flower, because the plants just go to flower when they go outside. Ed Rosenthal said you just need a few minutes of light through the night to break up the flowering cycle. It needs to be a strong light but it only needs to be on for 10 minutes through the night to continue the veg cycle. There is 2 things you can try. Chuck.
