How long can i expect this landrace sativa to stretch more?

I'm just finishing up a sativa grow (Tangerine Dream) and I've had the same problem... You can definitely do some LST on them to lower them down. I bought some LST clips and even at the stage you're in, you can find a pliable-enough section of the stem to use them on. These aren't the ones I got but there are lots to choose from... https://www.amazon.com/ZYP-Bender-Stress-Training-Cannabis/dp/B08ZRWKTW8/ref=asc_df_B08ZRWKTW8/?tag=hyprod-20&linkCode=df0&hvadid=554082837318&hvpos=&hvnetw=g&hvrand=11140974610489266329&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9002619&hvtargid=pla-1461648880206&psc=1 If I measured every bend and curve I put my ladies through, they'd be over 50" - in a 60" tent!! I even tried to do LST on a stem that wasn't optimal and it ended up being HST! That was the main cola and I was very worried - but it didn't harm her at all and she kept right on growing and growing and growing and growing.... Yup, that's a sativa!! From now on, I'm only going to have ONE sativa in my tent - they not only get very tall but they can get very wide as well! Oh... one more thing... I worried about them getting too close to the light (which they definitely would have - they would have grown PAST the light even though it is now resting on the top frame of the tent instead of hanging ... but these guys don't seem to mind being inordinately close to their source of light... mine is now just about 3" from the light and it makes no difference to them at all... DO do a lot of defoliation to get light down beneath as your harvest will reward you! One thing I'm having to do now is harvesting over a few weeks time... the top 1/3 is harvestable but I'm letting the bottom grow out more and that's proving to be a good choice... the lower buds are fattening up and ripening nicely.
