Z42 phenohunt

ThatsmyGrow 🌱 Week 1 – Z42 We’ve officially completed the first week 👀🔥 One Z42 unfortunately didn’t germinate, but all the others made it through and are developing well so far 🌱 Since we’re still in the very early stage, differences are still minimal and right now the focus is simply on building healthy roots and creating stable conditions before making any decisions. This week also showed one thing pretty clearly — I had the light intensity set too low at the beginning, which caused the seedlings to stretch more than intended. Combined with the higher temperatures, that effect became even more noticeable. To support root development, today I gave 4 ml/L Clonex Start. Once they move into the bigger pots, I’ll transplant them a bit deeper to counter the stretch and encourage stronger growth. 📈 Current observations: • One seed unfortunately didn’t germinate • Remaining plants established well • Some stretching due to low light intensity early on • Higher temperatures amplified the effect • Overall healthy development 🌱 📊 Current environment: • Temperature & humidity monitored • Light intensity adjusted moving forward • 4 ml/L Clonex Start added today • Bigger pots planned next The next couple of weeks should start revealing much clearer differences between the plants 👀🔥 That’s usually when each one starts showing its own character — and in the end we’ll compare all of them together to decide which one we’ll keep. 💬 Which one are you guys keeping an eye on already?

ThatsmyGrow 🌱 Week 2 – Z42 Another week is officially done 👀🔥 This week we transplanted the plants into 2.5L pots to continue supporting healthy development. After transplanting, each plant received 0.5L of water with 4 ml/L Clonex Pro Start. After the stretching from the first week, moving into bigger pots also gave the opportunity to set them deeper and create a cleaner base moving forward 🌱 📈 Current observations: • Transplant into 2.5L pots completed • Plants recovering and settling in well • Focus remains on healthy root development • Overall growth continues to look good 📊 Current environment: • Stable temperature & humidity • Light settings adjusted • Watered with 0.5L + 4 ml/L Clonex Pro Start after transplant The next weeks should slowly start making differences between the plants more visible 👀🔥 At the end we’ll compare all of them together and decide which one will stay. 💬 Which one are you keeping an eye on already?

ThatsmyGrow 🌱 Week 3 – Z42 Another week is officially done 👀🔥 The Z42 is showing taller growth already — pretty typical for a Z type. Despite the longer structure, development overall looks healthy and vigorous. Roots are already coming out of the bottom of the pots and they’re thick and healthy white, showing strong root development 🌱 This week we also started giving the first nutrients from Hy-Pro. 📈 Current observations: • Taller growth pattern — typical for a Z • Thick white roots coming out of the bottom of the pots • First Hy-Pro nutrients introduced • Excellent leaf color overall 📊 Current environment: • RH: 60–65% • Temperature: 24–25°C • Light intensity increased to 35% The next weeks should slowly reveal more noticeable differences between the plants 👀🔥 At the end we’ll compare all of them together and decide which one we’ll keep. 💬 Which one are you keeping an eye on already?

ThatsmyGrow 🌱 Week 4 – Z42 Another week is in the books 👀🔥 The Z42 continues to show the growth pattern I expected. The main stem is developing strongly and the plant is pushing upward with good vigor. The nutrient program is working well and the leaves are maintaining a beautiful dark green color. 📈 Current observations: • Healthy overall growth • Nutrients are being accepted very well • Dark green, healthy leaves • Strong main stem development • Typical vigorous Z-style growth 🌱 📊 Current environment: • Same nutrient schedule as last week • Temperatures have increased slightly • Humidity has decreased a little • Plants continue to perform well The differences between the plants are becoming more noticeable every week 👀🔥 At the end we'll evaluate them all and decide which one earns its place to stay. 💬 Which one is your favorite so far?

ThatsmyGrow 🌱 Week 5 – Z42 Another week is behind us and everything is progressing nicely 👀🔥 With the roots now well established, we removed the root stimulator from the feeding schedule. The focus is now fully on vegetative growth. This week every Z42 plant was topped above the 5th node to encourage stronger side branching and create a more balanced plant structure. 📈 Current observations: • Healthy overall growth • Root stimulator removed from the feeding schedule • All plants topped above the 5th node • Side branches should now begin to develop more rapidly • Excellent leaf color 🌱 📊 Current environment: • Same nutrient schedule as last week, minus the root stimulator • Stable growing conditions • Plants recovering well after topping The next few weeks should reveal how each phenotype responds to training and structure. 💬 Which Z42 is catching your eye so far?

ThatsmyGrow 🌱 Week 6 – Z42 Another week is complete and the Z42 is continuing to develop, although it still seems to be the most sensitive one in the run 👀🔥 This week we did a light defoliation on all plants to open up the canopy and allow more light to reach the lower and side branches. The Z42 is showing some small issues again, as visible in the pictures. It looks like it may need some CalMag support, so that will be the next adjustment to help it recover and continue growing properly. 📈 Current observations: • Light defoliation completed • More light now reaches lower and side branches • Side branches are developing a little slower • Small leaf issues visible • CalMag will likely be added to support the plant • Overall growth is still progressing 🌱 📊 Current environment: • RH: 60–65% • Temperature: 24–25°C • Light intensity: 35% • Same nutrient schedule as last week, without root stimulator The next week will show whether the CalMag adjustment helps the Z42 settle in and push stronger growth again 👀🔥 💬 What do you think is causing the issue?
