Greetings all. I have some struggling seedlings I could use some help with. These seedlings are Day 3. I’m pretty sure I know the issue is environment related.
Mars Hydro TSW 2000 - 24 hour on until sprout
3x3 Tent
Biobizz Light
Grand Daddy Purp Auto Flower
Germinated in solo cups 1 1/2 cup bio buzz 1/2 cup EWC with clear wrap on top
Day 1 - Temp 82 Humidity 30%. Light Distance 40”. Removed wrap. Probably prematurely peeler all shells off. Cotyledons were all pretty much closed. Mid afternoon seedlings looked worse. Gave all 5 ml distilled water. Replaced wrap over cups to get humidity up. Started 18/6. Places humidifier in tent.
Day 2 - Morning Temp 77 Humidity 40. Seedlings looked a lot better. Removed wrap again. Gave 10 mil distilled water. Mid Day Temp 85 RH 35 Seedling health again started to decline. Moved light to 60”Left wrap off. Still 18/6. During lights on 12 midnight. Temp 67 left humidifier left on, 88 RH
Day 3 - Morning Temp 61 Humidity 45. Adjusted light to 36” as I don’t think it was heat stress from the light. Think the extreme temperature swings are severely affecting plants. Not watering today as I think Ioverwatering. Top soil dry beneath is still moist.
My question is since we are about to have a few cold days where I’m at. Would switching to 20-4 or back to 24 have a negative affect? I mean the plants are already hurting and I’m having a real hard time controlling temp.
