Curious how tall autos get?? Only have a 5 foot ta...

Hey! I wouldn't worry one bit! Autos don't grow that tall but given you've got less space with the lights I understand your concern. Either way, if you take a look at the strain specifics, she can stretch up a good bit but won't be a problem. Most harvested diaries with this strain are at 25-30 inches. If you're still concerned then go ahead and start doing some LST. You can gain a good amount of space by bending your girls to the side, that also helps to expose bud sites which s great for increasing the yield. Hope this helped. Good luck and happy growing!
