My setup: Lighting (CFL) - 2 120W Bright light, 2 120W Soft Light, 1 300W Soft Light. Running 24 hours Soil - Water - Tap water left to sit for 18-24 hours. Additional Nutrients - a few drops of superthrive in a large spray bottle, add water, shake and mist onto the plants and soil before watering. Temperature & Humidity - 76-82°F -- 40-50% Hour 0: I transplant from clones in rockwool, I loosened up the rockwill a little bit, and planted them level in my grow medium. Hour 6: Estimate internal temperature of grow box has risen from ambient (50°F) to warm (~80°F) Leave for a couple hours & come home with a temp/humid gauge. Hour 12: Found out after about 12 hours my box had gotten far too hot. I felt it and assumed it was low 90's, when I finally got my thermometer and humidity gauge up and running, I freaked out---- 106°F - I immediately shut the lights off, and went "fans only mode" -- moved the plants out of the light for about twenty-five minutes. I jigsawed out a large vent hole on the side of my box, hooked up a 12" fan and started blowing on high speed through the new vent. Hour 13: Plants back in box, lights on ----- Monitoring temperature hourly, box is at 59°F, about level with ambient. Hour 14: Box is at 69°F Hour 15: Box is at 75°F Hour 16: Box is at 78°F Hour 17: Box is at 80°F Hour 18: Box is at 79°F Hour 19: Box is at 78°F Hour 20: Box is at 80°F Hours 20-36: Climate maintained at a steady 79° and 40-50% humidity --- All three plants showing new growth, and wider leaves. I mist watered the plants with about 30 ounces of water/plant. Hours 36-48: At work - As I get home, I find one plant is very sickly, leaves drooping, looks completely shut down. Plant medium felt dry to touch, I gave the plant some water and added straws on the side of the pot to draw more moisture down to the base of the plant. Hour 57 - Wake up, check plants: Find this The sickest one is near the vent hole. I'm wondering if it got a dose of cold air? I'm confused. From most healthy to sickest: So when I found them this morning like this, the soil again felt pretty dry to the touch. I assumed it was probably lack of water. I applied a good dousing of h20, enough to soak the soil and drip out the bottom. Hour 64: Maybe I'm seing things, but might be signs of improvement? Help save my babies!!!
