I started the spring with the experimental "Black Mamba 42," and here are my impressions. The plant spent 108 days indoors. Roots appeared on day two, and the seedlings shed their seed shells on day four. The plant stretches significantly in height; I managed to fit it into a 130 cm tall grow box by topping it and training the branches outward with plastic clips. At day 108, the buds were still a bit small; they could have easily gone another 2–4 weeks. The scent was moderately intense—nothing overpowering. Visually, the buds turned out to have medium density. The maximum wet weight for the two plants combined was 300g; I expect to harvest a solid 50g dry. We’ll know the exact figure in seven days—I don't like weighing wet material with the stems attached. As for issues: one plant suffered from acidification around day 15 (due to a faulty meter), which severely stunted its growth. Towards the end, the grow box was hit by spider mites. I also left it on an auto-watering system (using a 15L jug) for a week, and it dried out a bit. I had another plant from an international seed bank in the same group for comparison, and it handled the identical conditions perfectly. This strain isn't the easiest to grow and is a bit finicky. It requires a 2-meter-tall indoor grow space; in a one-meter space, without bending or training, the tops will get burned by the light around day 30–40 from seed. Bottom line: I didn't love the strain, though I’ll give it another shot later with the remaining seed. I plan to try seeds from two other banks. I recommend this strain to anyone with a 2-meter grow box who enjoys long grow cycles and cultivating massive Sativa monsters—and to anyone wanting to support our local breeders. Thanks for the experience! See you in future reports.
