i've got 4 different strains (c99, mango, sweet tooth and c99 x ak47) outside in pots where they've been for nearly a month now and have shown very little to no growth as the temps are down in the low 40's at night...even though we get up to the high 70's during the day...same story with my friend doing c99's in the ground. it's just too early yet for normal growth but cooler temps should just slow them down until the real warm weather gets here...like mid-may or so.
