Aleks555 We are starting to grow a new autoflowering strain from 42Fast Buds under the number FBA2504. We don't know much about the strain yet, but we do know that its maturation period is around 70 to 80 days. For germination, we used a reliable method: paper towel and cotton sponge. In just 24 hours, the seed sprouted with a root about 1 cm long. The next step will be planting it in soil composed of: 50% black soil (chernozem), 35% coconut substrate and coconut fiber, 10% perlite, 5% expanded clay. We will continue to monitor its growth and share the results.

Aleks555 The second week of growth has started, and so far, everything is progressing smoothly. The plant is looking healthy and strong, responding well to the environment. During the day, the temperature can reach as high as 31°C, but on average, it stays between 27°C and 28°C, which is a good range for promoting healthy development. Humidity levels are maintained between 55% and 65%, which seems to be creating an optimal balance for the plant at this stage. The steady temperature and moisture in the air help ensure that the plant can absorb nutrients effectively and grow without stress. The plant is showing good vigor, and we are monitoring the conditions closely to make any necessary adjustments as it continues to develop. Everything looks on track for a successful grow!

Aleks555 We are entering the third week of growth for our FBA 2504 strain from 42Fast Buds, and everything is progressing beautifully. We've recently transplanted the plant into a 10-liter pot, giving it more room to thrive. Even though it's an autoflowering strain, we've decided to experiment with a 12/12 light cycle—12 hours of light during the day and 12 hours at night—to see how it responds. The daytime temperature peaks at 30°C, with an average range between 27°C and 28°C, while humidity is consistently maintained at 60% to 65%. The plant has reached a height of 14-20 cm and is already showing three sets of leaves. We're preparing to start low-stress training (LST) to help guide its growth. In addition, we've begun feeding our beauty with nutrients from Xpert Nutrients, and we’re really pleased with the results so far. The plant looks strong and vibrant, and we're excited to see how it develops over the coming weeks!

Aleks555 The fourth week of growth has begun, and our FBA 2504 from 42Fast Buds is thriving. After the transplant into a 10-liter pot, the plant has adapted well and continues to develop strong and healthy. Despite being an autoflower, we're experimenting with a 12/12 light cycle, and so far, the results look promising. The temperature remains stable, reaching up to 30°C during the day, with an average of 27°C–28°C. Humidity is maintained between 60% and 65%, providing optimal conditions for growth. The plant has grown noticeably, now standing between 20 and 25 cm, with well-developed foliage. We've started applying low-stress training (LST) to shape its structure, encouraging better light penetration and maximizing potential yields. Additionally, we continue to feed our beauty with Xpert Nutrients, and the results are already visible—strong, vibrant growth and lush green leaves. Everything is on track, and we’re excited to see how our experiment unfolds in the coming weeks!

Aleks555 We’ve officially entered week 7 with our FBA 2504 from 42Fast Buds, and the transformation is impressive—our girl is now in full bloom! After a smooth and steady vegetative phase, the flowering stage is progressing beautifully. The decision to experiment with a 12/12 light cycle for this autoflowering strain has proven to be an interesting choice, and so far, the results are encouraging. The plant stands tall and strong in its 10-liter pot, with a well-structured shape thanks to early LST. The climate remains stable with daytime temperatures reaching up to 30°C and an average range of 27–28°C. Humidity levels are consistently between 60% and 65%, which has supported healthy growth throughout the cycle. We continue to feed her with Xpert Nutrients, and the impact is clearly visible—dense flowering sites, vibrant foliage, and a healthy overall appearance. The aroma is starting to build, and the buds are forming with great structure and frost. So far, this grow has been a pleasure, and week 7 marks a crucial point where everything starts coming together. We’re excited to see what the final weeks will bring!
