Tent-X Ultimate Grow Challenge / WhiteEdge

02.04.2024 Continue into week 5 Replaced all filters in the system and cleaned them. Mixed a new batch with the following components: 60ml AN Connoisseur AB 3g Big Bud Powder 7.5ml Silica Total volume: 34 liters Electrical Conductivity (EC): 1.38 Target EC for this week: 1.3-1.4. Adjustments will be based on plant observations. Performed one long misting session (3 minutes). Removed a few leaves from all plants, specifically the larger fan leaves from the middle of each plant. Environmental Conditions: Humidity is ideal these days; the dehumidifier runs only a few times per day. Observations: Smallest Wedding Cheesecake: Significant stretching over the past two to three days—from smallest to almost tallest! Unexpected! Tropicana Cookies: Phenomenal strain; I’m quite fond of it so far. Purple Lemonade: Buds are fattening nicely; high expectations for all three cultivars. Lighting Parameters: PAR Map: Maximum PPFD is 1050, minimum PPFD is 650. VPD: Ranges from -1.2 to -1.3. Daytime Temperature (DT): 24-26°C. Nighttime Temperature (NT): 20-21°C. Leaf Temperature: 22-23°C. Light Distance: 45-55 cm from the plants. CO2 Levels: 700+ ppm. Lighting Schedule: HLG Scorpion Diablo: Set at 70%, positioned at a 45-55 cm distance. Daytime: ON for 60 seconds, followed by 20 minutes OFF. Nighttime: OFF for 60 seconds, followed by 30 minutes OFF. Nutrient Tank (NT): pH: Maintained between 5.90 and 6.10. EC: 1.34. Temperature: 20-21°C 03.-06.04.2024 I’m leaving the city for 3-4 days, so I need to prepare enough liquid for the upcoming period. Mixed a 60-liter solution with 2ml AN Connoisseur AB + 0.3g Big Bud per liter. The liquid temperature is 19.8°C. Cleaned the water chillier and started it with a set temperature of 21°C. With this adjustment, the liquid will fluctuate between 21°C and 22°C before the cooler activates. Ladies, take care while you’re home alone! Lighting Parameters:PAR Map: Maximum PPFD is 950, minimum PPFD is 550. VPD: Ranges from -1.2 to -1.3. Daytime Temperature (DT): 24-26°C. Nighttime Temperature (NT): 20-21°C. Leaf Temperature: 22-23°C. Light Distance: 45-55 cm from the plants. CO2 Levels: 700+ ppm. HLG Scorpion Diablo: Set at 70%, positioned at a 45-55 cm distance. Misting Schedule: Daytime: ON for 60 seconds, followed by 25 minutes OFF. Nighttime: OFF for 60 seconds, followed by 35 minutes OFF. Nutrient Tank (NT): pH: Maintained between 5.90 and 6.15. EC: 1.38. Temperature: 20-21°C 07.04.2024 The external temperature is in summer values, and the temperature inside the room and the grow box is starting to rise. Unfortunately, the window air conditioner has stopped working, and this happened just when it’s most needed. To reduce the temperature in the grow box, I’ve dimmed the reflector to 60% light intensity. Better to have less light than overcooked buds, right? After being away for 3 days, I first replaced all the filters and topped up the reservoir with more liquid. In a few days, I plan to completely empty the reservoir, clean it, and start with a fresh, clean nutrient mix. Although I initially intended to exclude Silica from the next watering, due to the high temperatures, I’ve decided to keep it in the menu throughout the entire next week (6th week of flowering). Before leaving for my trip, I filled the 60L reservoir with nutrient solution at an EC of 1.4, while the initial level was 1.28EC and 45 liters less than what I started with. The ladies are still drinking their nutrients happily, and the nutrient strength has slightly decreased, which is excellent! VPD: Ranges from -1.2 to -1.3. Daytime Temperature (DT): 25-26.5°C. Nighttime Temperature (NT): 21-22°C. Leaf Temperature: 22-23°C. Light Distance: 45-55 cm from the plants. CO2 Levels: 700+ ppm. HLG Scorpion Diablo: Set at 60%, positioned at a 45-55 cm distance.

EC: 1.30. Temperature: 20-21°C Week 5 off Flowering in Summary 120 litter off RO water, 210ml+210ml AN connoisseur A+B, 18g Big Bud Powder, 45ml Growth Technology Liquid Silica 65kW electricity in total for light, Pumps and AC Infinity Fans. 60kW for Light + 2kW Dehumidification + AC Infinity ventilation Week start @ 1.38EC, nutrient strength., keep strength @ 1.3 till the end of the week Girls progress great all time, Wedding Cheesecake have two pheno, really like buds on one girl. Hard buds with tropical scents. Tropicana Cookies fill bud sites this week a lot, Purple Lemonade is going to be tallest from all three stains. Nice bud formation also. PH was stabile and move from 5.90 min to 6.2 max. Light distance for this week - 50-55cm from tallest top , PPFD levels around 950 in center, trough whole week. Lowest reading 680 @ corner Need to adjust light intensity, high temps outside Temperature are from 23c at start off day to 26c max at some points. AC Infinity T6 extracting fan program in AUTO to kick in @ 26c Unfortunately window AC is stop working, its hard to remove it from box right now, it will waith for harvest and after that i will see what to do Night temps around 21-23c, dehumidifier work less this week. Outside humidity is low this week Water temperatures in middle off week start to rise, refilling solution is cooled to bring temp back from 23-24 to 20c Will see next week outside condition's, hope it will bring back temperatures a bit Day RH is moved from 48% to 50% max, at night times drop to 40-45% Light Parameters: PAR Map: Maximum PPFD is 950, minimum PPFD is 650.
