It is currently 11:30 am where I am. I went to bed at 4:30 and shut the door to my grow room (which i always keep open during light period) because my cat was somewhere in the room but I didn't know where. Flash forward, I just opened the door and it is 97 degrees! I'm really worried about my babies. I'm working to get the temperature back down but I was wondering if anyone knew if there could be any real lasting stress or harm to the plants from such a high temperature. I've read that heat will stunt growth but I don't know if that means while the plant is under the heat or that the heat will cause long term effects. If anyone could clear this up it would be much appreciated.
Hi friend! When you correct the temps the plant will go back to normal growth. Those high temps stops all growth though, for now...
Hi there! Please give us some information! Thanks What type of medium; soil or hydro? What brand and type of soil? Indoors or outdoors? What strain? How old are the plants? What type of lights and how many watts? How far from the lights? What is your watering frequency and source of water? What, how much and when was it fed? NPK? What is the medium/runoff pH and PPM if in hydro? What are the temps and humidity in the room? What size pots? Any bugs? Look real close. Any other pertinent info? If any of these questions have already been answered please disregard as I cut and paste this for everyone. If there is leaf discoloration please TAKE PICTURES WITH ALL GROW LIGHTS OFF, ESPECIALLY HPS & LED's. Taking pictures and taking them with lights off, allows us to see what the leaf discoloration looks like.
So if my night time temps were too high all throughout my grow would that mean that my plants really aren't resting at all during their off cycle?
The warmer it is, the more water the air is able to hold. This moist air often refrains plant functions and decelerates growth. Other complications and problems result from excess humidity and moisture condensation when the temps drop at night.
At 97 degrees, they can't relieve themselves either through transpiration. The stomata won't open. They won't use much water or nutes.
