I grew Positronics, Cum Laude once. I got a freebie last year from the Tude. If the Claustrum is similar, you will want some LST. It was tall, slow and very beautiful. It grew long tall, pinecone shaped colas with lots of fox-tailing the last two weeks. Awesome haze smoke with pine and lemon taste and smell. I decided after that one, that I would save my sativas for outside next time.
I only flower around 10 at a time in a perpetual, and watching it flower for three months took patience.
Awesome smoke and everything of Positronics I have grown is great and stable genetics. I ran their Jack Diesel for four runs and that smoke was just as good with a ten week finish. I also ran their Somango 47 last year. That was more of a indica dom though.
I think sometimes throwing a little indica in to make a 70/30, or 80/20 sativa dom hybrid, gets you the same sativa buzz, but shortens the finish time by a month.
I would deffinetly grow anything they have though,
