i have no clue and i dont think my girlfriends brother does either (hes helping me) 1.we started them out on 12/12 for like 2/3 weeks not knowing. 2. we called my girlfriends uncle. (shown in hightimes like 6 different times) to see what light cylcle it should be on and he said 6/18 so we put it on that for about a week. 3. for some reaon about a week after it being on 6/18 my girlfriends brother changed it back to 12/12 and now its been on 12/12 again now for like a month.
let me know if this is gonna make our bud real bad because right now im clueless. this is one of my first successful grows hah.
