this lighting regime would really only be beneficial if you are short of head height and have some lanky pure sats . seeing as it's taken this long to get tham that big, it seems you might be better off doing 18/6 for a week or so then doing the flip to 12/12 IMO.having said that. i certainly wouldn't change anything now, and ruin the experiment totally. stick with it and note the results for next time.it's all an adventure growing canna
