Growing in Michigan can be humbling. Night time fog during the summer and heavy rains on your maturing buds in the fall. I have finally wised up and now use Mandalas outdoor guide. PPV gives large quantities of mildew free buds that work great to control pain. Highly recommend.
Grew a purple pheno at 37N in a 10 gallon pot. She jumped up to 7' tall with long, lanky branches by midsummer. I had no issues with mold or pests the whole season. The flowers were a stunning purple and blue amid a backdrop of light green leaves with an aroma of candied limes and a floral musk. High is relaxing and adds a sort of weightlessness to the body, but this plant is the most visually augmenting strain I have tried. My eyes tell me I am on a half eighth of mushrooms, but my mind and body are clear and relaxed.
This variety has been a consistent performer outdoors at 50 North since it's release some years ago. You will need to use quite a few sativa training techniques or you will have to grab a ladder for your harvest! As mentioned by the other reviewer here there are basically two types that show up, purple or green. I find the green one to always be the fence breaker ;), she has crazy compound branching and will put on huge overnight growth when conditions are right so get out your pruning shears and heavy duty twine. The purple types are often a little better behaved but will benefit from shaping and pinching out.
Although these Bhutanese beasts go to the late end of my season they can really handle some poor conditions, like our inland fogs and exposure to high winds and rain. You will need some staking and pay attention to airflow through the canopy however, no flowering cannabis plant is totally weatherproof.
All this vigour in PPV means a bit of work but your efforts are amply rewarded in flowers! No super dense nugs here but ample weights through sheer biomass. I tend to make hash from my plants and often produce something similar to some of the high quality Lebanese that used to get around a few decades back, a wonderful treat that keeps me smiling through the year.
Highly recommended variety for anyone who has a less than perfect climate, one or two of these make a beautiful addition to any outdoor garden.
Purple Paro Valley (PPV) this is an odd duck. First of all note the elevation it grows at in Bhutan. If it grows there it can grow anywhere were my thoughts. From my grow 3 years ago, I had 2 distinct pheno types; one producing small purple buds, the other, well tell ya bout that in a moment.
Both phenos have long internodes and are defiantly "sativas". The girl with the purple buds had bright purple stems as well. The reason the buds were small was do to my tyro efforts as a grower at the time. The buds were a trimmers delight. The Other gal was another story. First off let me say when you grow PPV by all means take the advise and remove the lower branches. This female was very stretchy in the internodes as well, and had deep purple stems like the other. Now here is the kicker. (Disclaimer: This is NOT a hippie story, and I promise you it is a factual account, skepticism gladly appreciated). When mature at the end of September after being started in a makeshift greenhouse around tie ides of March, the finished plant was 6 feet tall and 32 feet in diameter. For real. The "buds", 3.5 dried lb of them were very loose, lime green, looked like foxtails and had no bag appeal at all. It was some of the absolute best smoke we produced that season. 2 pounds were made into shatter,, and the rest was personal stash. The purple buds although small, had Great bag appeal, and had the same wonderful buzz. The claimed THC for this strain is 8.7 to 11 %? I call Bullshit on that lol.
This year i have PPV in my roster in a 300 gallon grow bag. I have passed the seeds out to friends and family and we see what we get this season. Recommended!
