That's an unknown strain from wherever the Jamaican grower got it from, lol. I used to trade with the Jamaicans in the mid '80's. It's not worth it. Yeah you used to get Lambs Breath back in the day. Now everybody is into Pineapple Express and other popular names. They love the shorter time and great yields of hybrids.
What you got ain't Lambs Breath (what everybody thinks they want from Jamaica), it's something somebody traded for, and then grew out and made more seeds for themselves.
And LB is not a Jamaican land race. It's most likely a Colombian strain that came over ages ago. And it sucks to grow, lol.
I quit trading seeds with those guys a long time ago.
I used to go 2 and 3 times a year for quite a long time. Worked a bit there as well. I don't go anymore, now that I've lost a few friends there.
Grow it out, no different than buying from a seed bank except it may not be bread as well.
