HandsomeTerpz Iโ€™m seriously lucky to be part of the beta test for Doctorโ€™s Choice (DC) and their new strain Black Mamba. Honestly, I canโ€™t even describe how excited I am about this. Over the next few weeks, Iโ€™ll keep you fully updated: from growth and structure to aroma and effects real talk, no hype. ๐Ÿ‘‰ Follow me on Instagram to stay in the loop. This journey is just getting started, and Black Mamba already shows real potential.

HandsomeTerpz Strain: Black Mamba (Doctorโ€™s Choice) -------------------------------------------------------- Grow Type: IndoorMedium: Light-Mix soil with perlite & worm humus Lighting: 18/6 Pot Size: 0.5 L Day Temperature: 27 ยฐC Night Temperature: 23 ยฐC Humidity: 75% pH: 6.0 Lamp Distance: 50 cm Watering: ~0.1 L per plant / 24h Plant Height: ~8 cm ---------------------------------------------------------- The last two weeks have been going really well so far. Both seeds germinated extremely fast within 24 hours and showed strong, healthy growth right from the start. For this run, I decided to germinate the seeds using the paper towel method (kitchen towel), and the results were excellent. Strong taproots developed quickly, and the seedlings transitioned smoothly into the soil. Now in week 2 of vegetation, the plants look compact, vigorous, and well-balanced. Internode spacing is tight, leaves are healthy green, and growth speed is impressive for this early stage. Environmental conditions are stable: Temperatures are right where they should be Humidity is slightly on the higher side, which is perfect for young plants pH is dialed in at 6.0 Light distance feels spot on with no signs of stress No issues so far, no deficiencies, no stress symptoms. Overall, this has been a very smooth and promising start, and Iโ€™m really happy with how fast and strong these Black Mamba girls are developing. Looking forward to the next phase โ€“ if they keep this pace, this grow is going to be a lot of fun. ๐ŸŒฟ๐Ÿ

HandsomeTerpz Week 4 ------------------------ Is going strong exactly how it should be ๐Ÿ’ช After transplanting into the final pot, the plants once again recovered extremely well. No slowdown, no stress โ€“ instead vigorous growth, clean leaf structure, and clearly visible new vitality ๐ŸŒฟโœจ The combination of BioTabs Bactrex & Ocratex is doing an excellent job in the root zone. The soil is alive, and the plants respond immediately. Minor nutrient deficiencies that appeared briefly were brought fully under control with Boom Boom Spray ๐Ÿš€๐Ÿƒ. Leaf color and turgor bounced back fast. What stands out: The Black Mamba was far less affected by the deficiencies than the other genetic. Right now, she looks extremely stable, resilient, and vigorous ๐Ÿ๐Ÿ’š exactly what you want at this stage. Current conditions based on setup & image data: ๐ŸŒก๏ธ 27 ยฐC day / 23 ยฐC night โ€“ stable and optimal ๐Ÿ’ง 75 % humidity โ€“ perfect for vegetative growth ๐Ÿ’ก 18/6 light cycle, lamp distance around 35 cm (400 PPFD) ๐Ÿ“ Plant height approx. 25 cm ๐ŸŒฑ Final pot: 12 L โ€“ plenty of room for strong roots ๐Ÿšฟ about 1 L water per plant / 24 h, pH 6.0 ----------------------------------------- ๐Ÿ‘‰ Very healthy development, strong momentum. If things continue like this, the plants are perfectly set up for a powerful end of veg and a smooth transition into flower ๐Ÿ˜Ž๐Ÿ”ฅ

HandsomeTerpz Doctors Choice Black Mamba Vegetative stage week 5 The Black Mamba from Doctors Choice shows a very balanced and healthy development in week 5 of the vegetative stage. Growth is compact and controlled while still producing strong branching and solid internode spacing. With a current height of around 30 centimeters, the plant is developing exactly as expected for this stage. Environmental conditions are stable and support consistent growth. The light cycle is set to 18 hours on and 6 hours off. Daytime temperatures are around 27 degrees Celsius with nighttime temperatures near 23 degrees. Humidity is approximately 75 percent. The plant is grown in a 12 liter pot using BioBizz Light Mix supplemented with perlite and worm humus. Lighting is provided by an Array 4x4 LED, ventilation by a 6 inch inline fan with carbon filter. The Black Mamba was topped in week 4 and handled the procedure very well. Since then, it has responded with strong and evenly developed side shoots. Overall, the plant appears robust and noticeably less sensitive than some other strains, making training straightforward and stress free. At this point, the Black Mamba leaves a very confident impression. Growth is stable, responses to training are positive and there are no visible signs of stress. If this trajectory continues, a strong and well structured plant can be expected for the next stage. Conclusion Very solid development with good resilience and control. So far, this strain stands out for its stability and uniform growth.

HandsomeTerpz Week 6 of veg and it clearly shows the Black Mamba Beta is fully dialed in. Growth is strong healthy and consistent. No deficiencies no issues the plants are running smooth and look very vigorous ๐Ÿ’ช๐ŸŒฟ At around 30 cm height with an 18/6 light cycle and stable conditions around 27 ยฐC daytime temperature and 75 % humidity everything is right on point. Previous topping and LST paid off nicely giving the plants a compact bushy structure that is more than ready for flower ๐ŸŒณโœจ Long story short no more problems everything is on track. This is exactly how a veg phase should look. I am really looking forward to the flowering stage things are about to get exciting ๐Ÿ˜๐Ÿ”ฅ ๐Ÿ‘‰ Next stop flowering phase lets go ๐Ÿš€๐ŸŒธ
