Plant Drooping After Introducing LED Growlight

lvstealth · May 4, 2021

It doesn't need to be accurate, just use it to start them, then she will take it from there.

Do it like hardening one for outdoors. A little while each day then gently increase. She doesn't get pouty till 10 hours, try 5, or if it starts bothering her at 5 try 3... Increase 30 min every day or two

I’ve had this problem running the Mars hydro sp3000 with white widows.

I had everything right (so I thought) from watering to nutes and everything in between.

I raised the canopy air temp from 77 to 82 during the day and they perked up.

I have an IR thermometer coming in today but going to guess that the leaf temp and temp at the roots was just too low.
This post is a couple months old and not sure if you figured out but just some food for thought.

Did you ever find out what the cause was? My plants looking like these, I've tried so many things and they came back to life after replacing led lights to 250w mh.
But then after 2 weeks they're dying again.

Hey everyone. I have a 2 month old plant in veg, and she starts drooping everytime I try to introduce my LED growlight.
I'm currently growing with a 20 watt LED (aquarium one), and I tried to change it to the other closet with a ViparSpectreV300, but she starts drooping everytime. I've tried placing the light further away, and its sitting currently at more than 3 feet above the canopy, while the manufacturer recommends keeping at 20 inches in veg, but already started drooping. What should I do?
And I know for a fact that its not overwatering/under or nute problems, because under the other LED she's completely fine with the same watering schedules. She droops after 10-20 hours of changing her to the L.
Also, I've tried sprouting a seedling under that Vipar, but she already started drooping aswell at the recommended distance of 30 inches, so I placed the light at 3 feet until it starts to get better (if it

Hi bud your plants are reacting totally normal I go through this every crop I start clones under t5 sunblasters once they root I put in small pots with the t5 for 18 hour's for 1 week. After they get established I bring them into the flower room under more t5 to supplement when not using the 1000watt led and introduce a phytomax-2 1000.... that's a 1000watt light at 54 inches I start the first day for 1 hour 2nd day 2 hours and every day 1 hour additional until about day 4 and they usually could handle that at 54 inches and I'll switch to 18 hours no more t5. Once they transition and could handle I start bringing the light closer everyday 2-4 inches everyday wtv they can handle until I reach 30inches gives about 900 ppfd the faster and younger you could do this the easier and faster they adapt

This is my ambient room temp I have an alarm that goes off at 78 just to advise me. At 78 my digital thermometer at canopy reads about 82.5 if it goes 79 I'll be at around 85 and I see they get stressed and I don't have co2 so I keep around 77-78max

That plant is struggling for 2 months old. Looks over watered. 18/6 is easier on them than 24 hours veg. I couldn’t get 24 to work. It will adjust to your light, might take a couple days.

I agree , plant is way to small for that size plant. Your watering ever 3-4 days then that plant is dead. A plant that size in as big a pot as that should be watered every 2 weeks.

Cannabis naturally droop wen it is tired or acclimating. These are 2 plants I grew inside a metal building during the winter and are 6-7weeks old. Transplanting late, was using 2-30watt lights LED and a 18w LED. Got a 300x10w=3000w running off 600watts. And I think someone left a light on today. My plants are experiencing fatigue. I was thinking bout letting them rest till the leaves popped back up. I’m 24” from the canopy, but the roots may be cold. I usually grow outside. so I never have these problems..stunted growth, cold, fishbowl environment, or unnatural lighting

I’m running humidifiers during the day, the light at night ; Starting with Bloom ONLY, and then adding Veg/Bloom the plant have time to adjust before major transpiration happens and stomata open for the passage of CO2 and O2 during photosynthesis. The humidifier helps during the day to revitalize the leafs before the heat! Rinse and repeat. The biggest problem I’m dealing with is I wanna water the plants and it is kinda too cold at the moment. the soil is damp, so it should be ok. But it is time for a watering! 2/3/23 and the ice storm has been a contributing factor!

These plants should be 4feet tall..I’ve never grown Auto, so planting them into their main pots is a big deal! And Fem are easier to get bigger buds vegetative stage is longer or shorter whatever u want. I find Fem and stander seed easier to grow because they grow slower. I transplanted these late and it was cold. Ready for March 8-18th outside growing!

2/3/23 10:15pm and they doing really good after 5hours of light!

Jrspeed70791 · Feb 7, 2023

I’ve never seen a plant droop over the way ur plant was drooping. Mine was cold the environment. They’re doing good now, last picture. I pruned the first today and will do the second in a week from now. GL on ur next grow!

Right now my plan is the following:
- Seedling
Keep it under the vipar at 3 feet
Place the vipar at an angle so the light isnt directly towards the plant
Keep the humidity high to cope with transpiration of the leaves

- 2 Month Old Plant
Keep it under the 20w LED until it recovers fully (Maybe 3-5 days)
Slowly introduce the Vipar to it, by placing the plant in the vipar closet 2 hours each day, with the light at 3 feet and at a 45-60º angle directed at the wall
Add 1 hour under the Vipar each 1-2 days, and if she starts to stress again, reduce 1 hour again.
Whenever she gets to 18/6 without getting any stress, start to lean the light directly again at the plants
Decrease the distance from the canopy to the light by 2-4 inches every 2-3 days.

I'll keep you updated every week and see if I can pull this off. Any other recommendations are fully accepted and aprecciated.

Honestly, if you want to do that all sure, otherwise

Eventually, it'll be fine, surely, just leave it under the vipar move it to the side for less intensity
