I'm just now running short of my short ryder (Nirvana) after a year of mellow toking. I had trouble getting the light right--20-4, 12-12, 18-6. 12-12 to finish with about a light oz. from each of two. I must say, after a year in bottle, opening and closing, I up my eval: 8/10. For this year's grow I started with 2 Northern Light and 2 Skunkberry (from PeakSeeds BC), and 2 Jock Horror Fem (from Nirvana). The Skunkberry were both male, as was one of the Northern Lights. The other Northern Lights hermied at about 6 weeks. I had to flip the lights early when the Skunkberry took off, and I hadn't staggered the start times, so my Jock Horrors, much slower than the Skunkberries, only grew to 17in. Dumb mistake. But it's drying, and I'm still figuring an oz from each. And they're sticky and the smell is wonderfully dense.
