Two Weeks of Hard Work: Updates and Progress!

Hey everyone! I’ve been super busy these past two weeks but finally have time to update you on all the work that’s been happening. Things are moving forward, and I’m excited to share what I’ve been up to:

• Nematode Army: I’ve been growing nematodes to help control the fungus gnats in the soil. They’ve been doing a great job keeping those pests at bay. Alongside that, I started using diatomaceous earth to tackle any remaining critters.
• Third Net Installed: After adding the third net, I’ve been working on selecting which buds to keep. This will help focus energy on the strongest buds, leading to bigger and more potent flowers.
• The Table: I’ve created The Table, a detailed daily schedule that outlines everything from temperature, humidity, and light levels to VPD and airflow for every stage of the plant’s day. It ensures I’m optimizing the environment throughout the entire light cycle. I start the plants with lower light in the morning, increase the intensity to medium during midday, and then taper it off again in the evening, following the natural light rhythm plants respond best to. It’s helping me stay on track, and I think it’ll be a game changer. Feel free to comment with suggestions! I’m always looking for ways to improve and maximize efficiency.
• PPFD Meter App: I’ve also been using a PPFD meter app that’s been incredibly helpful in measuring light intensity without having to drop hundreds on a quantum meter. It’s a great alternative and allows me to fine-tune my light settings throughout the day, ensuring the plants get the right amount of light at the right times.
• New Gear: I invested in an AC Infinity Thermoforge T3, and it’s been a huge help. The precision I now have over both temperature and humidity has allowed me to create the best environment possible for the plants as they enter these crucial flowering weeks.
• Hoverfly Larvae On the Way: Today, I’m going to sprout hoverfly larvae (Florfliegenlarven). These little predators will take care of spider mites, fungus gnats, and basically anything that moves—even each other if needed. This should give me a pest-free month to finish flowering in peace.

I’d love to hear any feedback or suggestions on how to improve things even more if someone is interested I could also post, “The Table” Drop a comment below and let’s chat.

Managing Light and Growth – A Day of Defoliation

Trimming Back for Better Light Penetration and Healthier Growth

Today, I had a bit of a green thumb adventure in the grow tent. Due to my large pot sizes, the plants have been growing vigorously, and I had to step in for a little defoliation session. With the plants getting bushier by the day, I noticed they were beginning to shade themselves, preventing optimal light distribution.

So, out came the scissors! 🌿✂️

I took off a significant amount of fan leaves to improve airflow and light penetration. To give you an idea of the amount removed, check out the picture below. I laid out a meter beside the pile of cut-off plant matter for reference. This should help you visualize just how much plant material was removed – the size of the pile is almost surprising!

After the defoliation, I made sure to water all the plants with the right proportion of nutrients. It’s crucial to maintain proper feeding, especially after a defoliation session, to support recovery and continued healthy growth.

But that’s not all—I also made a key adjustment to my light setup. I noticed yesterday that some leaves were getting a bit too toasty, which was a clear sign they were receiving too much light. My Lumii 720 LED light has been a beast, but I prefer it to be further away and let the plants indicate when they’re comfortable. So, I raised the LED light to the top of the tent to give them a break from the intensity.

Now, it’s all about observing how they respond. I’ve found that plants are quite communicative. When they’re happy, they let you know! 🌱💡

Key Takeaways:

1. Defoliation: Helps improve airflow and light penetration, especially important in setups with larger pots.
2. Nutrient Balance: Proper feeding after defoliation is critical for a smooth recovery and sustained growth.
3. Light Adjustment: Raising lights can prevent plant stress from excessive light exposure. Watch your plants and adjust accordingly!

Nematodes: A New Ally in My Grow

I’ve heard a lot about the benefits of using nematodes to keep unwanted pests under control, but I’ve never used them before. After doing some research and getting quick advice from the amazing folks over at the Mary Jane Community, I decided it’s time to give them a try. I just ordered a bio product containing beneficial nematodes, and I’m excited to see how they work in my grow.

Nematodes are tiny, microscopic worms that naturally occur in the soil. They target and eliminate soil-dwelling pests like fungus gnat larvae, which can be a persistent problem in indoor grows. Using a biological control method like nematodes not only protects the plants but also maintains a balanced and healthy growing environment.

The support and fast response I received from the Mary Jane Community made me feel so thankful to be part of such a knowledgeable group. I’m happy to keep learning and share my experiences along the way. I’ll keep you all updated on how the application goes and whether these little helpers live up to the hype!

When I decided to upsize to larger fabric pots for my cannabis plants, I knew I’d be providing more space for the roots to expand, ultimately encouraging stronger and healthier growth. But I quickly realized that the added soil volume and root space came with its own set of challenges—especially in my fixed grow tent area. The Initial Thought Process Larger pots mean bigger plants, right? That’s exactly what I was aiming for—vigorous growth, increased yield potential, and a robust root system. Fabric pots also offer better aeration and reduce the risk of overwatering by allowing excess moisture to evaporate. However, I didn’t fully consider how this change would impact my grow environment. Managing Plant Size in a Fixed Space As the plants grew, I found myself constantly having to control their height and shape to prevent overcrowding. The extra root space resulted in a surge of vegetative growth that pushed the limits of my tent’s vertical height and canopy area. Here’s how I tackled this issue: 1. Topping and Training: To keep the plants at a manageable size, I used topping techniques early on and applied Low-Stress Training (LST). This allowed me to shape the canopy horizontally rather than letting the plants stretch vertically. The goal was to create an even canopy that maximized light distribution. 2. Defoliation: With the denser growth, I had to remove excess fan leaves and lower foliage to improve airflow and light penetration. This step was crucial in preventing mold and mildew, especially with the increased humidity that came with larger pots. 3. Monitoring Moisture Levels: Larger pots hold more soil and retain moisture for a longer period. I found that watering schedules needed adjustment to avoid waterlogged

When it was scheduled for a trim I found some little small flies, currently controlling them with some sticky traps. Seems to be keeping the population of them at ease.

I’m catching three to four flies per day at the beginning, maybe one per day. I setup the traps in all plants, three traps per plant.

All plants are being feed 1 Liter of water every two days or until the soil is dry.

Using Plantagron Flower 2 ml/L, reducing down to 2 ml/L Bio-Grow, Bio-Heaven 2 ml/L, Bio-Bloom 1 ml/L, CalMag 0,5 ml/L, Top-Max 1 ml/L.

The tops looks slightly over feed so I’m going to water them next time with only some CalMag and unclohrinated water for them to absorb the excess without the need of a flush.

Bought two new Ac Infinity fans, I would highly recommend these for various reasons. First, I can move heat and humidity around the tent to get more consistent readings. Second those fans let me adjust the angle and how wide the fan throws air so it doesn’t touch the sides of the tent. Therefore allowing the fans to work silently and have no stress against the tent itself, which usually breaks down the oscillation feature of the fans.
In total I have three fans moving air. One dedicated to move air under the canopy and two above to keep the canopy moving as to a slight brease intermittently.

Over the past week, I’ve made significant progress in my grow setup:

1. Transplanting Persian Pie Seedlings:
• I transplanted four of the Persian Pie seedlings into their final 35-liter soft pots, providing plenty of space for root expansion. The fifth seedling was placed in a 15-liter squared plastic pot. All are in their second week of vegetative growth and have adjusted well with no signs of transplant shock.
2. Blueberry Plant Transition to Flowering Stage:
• My big Blueberry plant has started the flowering stage under a 600-watt HPS light, currently set to 400 watts. The light cycle is set to 12/12 hours to induce flowering, and the plant is responding positively to the change.
3. Nutrient Protocol Update:
• Today, I switched to the flowering nutrient protocol using Biobizz products, aimed at boosting bud development and providing essential nutrients during this phase.

Environmental Conditions:

• Both the Persian Pie and Blueberry plants are thriving in temperatures between 24 and 26 degrees Celsius. They are being watered with plain, unchlorinated water at a pH of 6.3.

Watering Schedule:

• Each Persian Pie plant is drinking about 1200 ml of water.
• The Blueberry plant is consuming nearly three liters every two days, reflecting its increased needs during the flowering stage.

Current Observations:

• The Persian Pie plants display healthy growth with robust leaf structure and no visible nutrient deficiencies.
• The Blueberry plant is adapting well to the flowering conditions, and I am closely monitoring nutrient uptake and flowering progression.

Next Steps:

• Continue monitoring light intensity and plant responses, especially after increasing light settings for the Persian Pie plants.
• Keep tracking the Blueberry plant’s flowering phase and adjust nutrients as needed.

Stay tuned for more updates as the flowering phase progresses and the Persian Pie plants continue to thrive in their vegetative stage!
