Extreme - 10 °C Cultivation: When Nature Meets Innovation

HoneyBlunt42 🌱 Day 6: Bifurcation Point 🔬 Today is a critical moment. The temperature drop to +3°C became a real exam for our experiment. The 250W DNaT lamp is our last advance of life. 🌡️🚨 Plant status: First: Good Second: weakening, but holding on 🌿 Third: grew a bit! 🚀 Interesting observation: the plant that stretched 4 cm shows the highest stability. Perhaps we're witnessing natural selection right in our experiment. Current action points: Constant temperature monitoring Minimal intervention Documentation of every change 📊 Science is not only about triumphant moments, but also about survived challenges. 🔬

Growth! 🌱 ____________________________________________ 🌱 "Hot Drama in the Growbox: When Plants Can't Take the Heat!" Fellow growers! Today we're analyzing an interesting case that shows just how crucial proper temperature control is for our green friends. 🌡️ Situation: - Temperature under the HPS lamp reaches +34°C (10°C above normal) - Current ventilation (profit4 d100mm intake, profit5 d125mm exhaust) can't keep up - Clear signs of heat stress in plants - Watering with reverse osmosis purified water, 100-200 ml per session Technical details in simple terms: Imagine your plants are stuck in a sauna - it's humid, but way too hot for comfort! When temperatures rise above +28°C, plants start to "suffocate" - their metabolism slows down and growth comes to a halt. Solutions recommended: 1. Replace HPS with LED lighting: - Less heat generation - More efficient energy use - Can be placed closer to plants 2. Ventilation improvements: - Increase exhaust fan power - Add intermediate fan for circulation 💡 Fun fact: The plant in the corner is growing better than others precisely because it's further from the "tropical heat" of the lamp - it's like a happy vacationer in the palm tree shade! Question for readers: Have you experienced switching from HPS to LED? How did it affect the temperature in your growbox? Share your stories in the comments! 🌿

HoneyBlunt42 🌱 Ventilation Magic: How Proper Airflow Transformed My Plants Hello, green enthusiasts! Day 22 of my plant experiment has brought some fascinating results. After installing a more powerful exhaust fan (280 m³/h), two plants have literally sprung to life and started growing vigorously. The third one is taking its time to contemplate life, but it's still making slow progress. 🔬 Technical Details: I've brought back the LED light, calibrating its brightness using the Photone app. An experienced grower shared their optimal settings with me – what a goldmine of knowledge! 🌡️ Microclimate: A cozy 26°C in the grow box (despite -12°C outside!) Humidity holding steady at an ideal 60% Light positioned 25 cm above the plants You know, my plants are like teenagers on vacation right now – two active go-getters and one philosopher who prefers to take life at their own pace. Have you ever experienced plants from the same batch growing at different rates? Share your observations!

HoneyBlunt42 Two plants have grown well after switching to 18/6. I hope the third plant will catch up to the first two soon. Growing on 24/0 was a mistake - stunted growth, too much heat. Day 28 - started stretching, watering with "Elixir #1 for seedlings NPK 3-1-1 to address nitrogen deficiency (red stems)

HoneyBlunt42 Day 31 - I started bending the tops of the first and second plants. To put it mildly, they are not large for sativas, but I'm not giving up. Maybe they'll stretch at least twice more. They started flowering today; I saw flowers on the tops. The third one is very small - possibly due to the cold. I wanted to move it to a 0.5-liter cup, but its roots have gone deep into the soil. I left it as is, maybe it will wake up. Even the medium root system gives hope. Day 34 - the first plant is feeling good and looks healthy. The second one looks unhealthy - it seems I overfed it with nutrients - dry tip ( The third one is very small - 5 cm and fits into a greenhouse made from a 0.5-liter plastic cup. I’ll try to water all the plants with plain water and see how they react.

HoneyBlunt42 Day 38 - 4 days ago, I watered the plants with pure osmosis water - until drainage. The fertilizer concentration is ultra-low. Before that, they got burned - nitrogen fertilizer in too large amounts. I had to cut the buds from the top by 1 cm - to stimulate the growth of the side shoots that survived. I'm gradually bending the plants so the sativa doesn't get burned by the light. Day 40 - the consequences of flushing with pure water until drainage - healthier plants. I'm happy and for now, I'm only watering with pure water and a drop of complex organic fertilizer.

HoneyBlunt42 Day 45 - I continue to gently bend the tops and stretch the branches with rubber bands. The plants are abundantly sprouting new small leaves around the flowers. From the bending, they will all be about the same size. The plants look healthy, even the third one - the smallest (11 cm) - is actively growing, stretching before flowering. One bud is definitely going to be there :) The plants were stressed at the start - it was hot, heat shock. That's why they are not large and have flowered small. I couldn't influence this process with the autoflowers and grow them to the desired size. Day 50 - the first plant shows good growth, has stretched a lot. It's standing in the corner, I’m not bending the faraway buds too much so they don't end up in the shade. In 5 days, it has stretched 3-5 cm on each bud. The second one is beautifully flowering, shorter in stature. It seems I bent it a lot. A medium smell has appeared. I'm trimming it and the first one from the bottom, removing unnecessary foliage from the base and small buds. They won't be able to develop in the shade of the upper leaves and buds anyway. The third plant is small, 15 cm tall. It's noticeably stretching, the central bud will be small for a sativa, but fat. I'm watering them with 0.2 liters of filtered water per plant. I'm not adding fertilizers, afraid of over-salting. I initially mixed bone meal and seaweed meal into the soil so that the plants would receive enough P and K during the flowering stage.

HoneyBlunt42 Day 58 The plants are starting to smell stronger. I set up an automatic watering system in the box with a tank filled with a flowering solution made from simple mineral salts. For the solution (g/10L): Calcium nitrate – 0.29 Potassium nitrate – 0.09 Monopotassium phosphate – 0.48 Ammonium nitrate (ammonium saltpeter) – 0.05 (optional) Magnesium sulfate – 0.50 I prepared this solution in a 20-liter tank for watering, installed a 3-watt pump - 285 L/h. And an air compressor - 2 watts - 1.3 liters/minute with an aeration stone. For acidification, I used citric acid (1.6 grams per 20 liters). I turn on the watering twice - at the beginning of the light cycle and at the end. For 1 minute each time.

HoneyBlunt42 Day 59 - first harvest! The first plant looked visually ready, so I chopped it down. I sent it to dry in a separate dark box with a carbon filter of 350 m3/h and an exhaust fan of 190 m3/h. The room is dark, and ventilation is a must. Temperature +25 Celsius - acceptable for drying. After 10-14 days, the finished buds will weigh 20% of today's wet weight. In the last weeks, I only watered with osmosis water.

HoneyBlunt42 Day 69 - second harvest. Today I chopped down the second bush - it was bigger than the first and third. Looks promising.

HoneyBlunt42 Day 79 - harvest of the 3rd plant The previous plants yielded 54 and 123 grams of wet weight. This one came out to 50 grams. I sent it to dry, just like the previous ones. Overall, I'm expecting about 45 grams of dry weight from the 3 bushes.
