I've only run two lines from norstar, the Solar wind, and Zapotec I'm currently running. Solar wind didn't stretch much, (although it's urkle/Chernobyl x purple meyhem, so lots of indica in there), of my two Zapotecs, one stretched so much I thought it was male before declaring, the other barely at all.
So, no more than anyone else as far as I've seen, unless you choose specifically sativa heavy genetics, which of course will be stretchy.
What are your thoughts on the solar wind? I've been sitting on a few freebies for some time now, doesnt seem a very popular strain
I chopped at 50 days, could have gone longer but had things to do in the tent. Smoked 3 hits off one Zapotec pheno and got a strong trippy high. Smoked 4 small hits off of another one and got a super strong high. Very intense and quite trippy. Was high 3 1/2 hours off the second one. Normal is 2 hours at the most. I got a little worried that my mental health had failed or something, but just a strong and long lasting buzz.
Very satisfied so far. Have 2 more phenos to test of the Zapotec.
