Your going to need a lot of support once that GT starts to bulk up.
But fuck do they look good!
Here's some photo's of the panama from 3 seasons ago. We finished the last bit of her (cob) a month ago. It was many peoples favourite. Very strong, uplifting and euphoric, but with much more body to it than the GT. Again another weed that really needs a good 6 moths in the jars to bring out its best qualities. TBH I wish I had some on the go, but have over 25 different sorts of sativas that I'm wanting to try and can only get away with 5 each season. For some strange reason I get gifted seeds from some very accomplished growers that are part of the cobbing forum that i hang out on.
Only last week I was offered 7 different rare indica genetics. I don't usually do indicas or hybrids because of the smell but am going to try to do a grow over winter and flower it in early spring. Not quite figured the logistics yet but hey ho
