If I put any hybrid or indica Cannabis plants out that early here they will flower here. Traditional seed planting time here growing outdoors is May 1. As Lebbies flower and finish early, they will set blooms if you put them out anytime near 12/12 which is everywhere worldwide at the spring equinox (March 20). You can stave off flowering by putting light on them at night. Or putting then indoors under lights.
What I do for a double harvest and early spring blooming is germinate them and size them up in pots indoors under 20/4 light. Then I set them out in mid April when it gets warmer here and they set blooms. Once in bloom they will continue to bloom regardless of the photo period. I let them go through the end of June before harvesting for short blooming strains. Then I let them re-veg under sunlight and they bloom again in the late summer and fall. That results in a double harvest, and a larger harvest in the fall from larger plants. For long period flowering strains (like Colombian) you may only get one bloom cycle, but they finish in September rather than in January. If they do not bloom outdoors in April, I light dep them to force them to. Some late bloom long finishing strains want more light dep to trigger blooming. I also trigger blooming on later blooming plants like Maui by light depping them in July to force them into an earlier cycle. Lebanese planted May 1 and left on its own will finish outdoors in September here.
