I recently started growing, and my babies are nearing their two-week birthday. For some reason, they are drooping. I’m not sure why. I am aware that I was overwatering for a bit; I purchased a moisture meter and that’s no longer an issue. I’ve been watering less and yet they continue to droop. The leaves also look rather dry. I’ve got a meter for every factor (except a light meter), and everything is within the acceptable ranges listed in Jorge’s grow bible. The only thing that’s wrong is my humidity, the highest it’s ever gotten is 39 percent, and usually it hovers near the low 20s. I’m not sure if this could be affecting my plants since apparently low humidity is unheard of in the cultivating community. I tried some homebrew methods of increasing the humidity and nothing. I even went so far as to buy a tiny humidifier, and it’s sort of helping, but the levels of humidity are still not near the acceptable ranges. What could be causing my plants to droop and look dry, and what can I do about it? Thanks for your time and your efforts. — Mario A.
Seems that you’ve diagnosed your problem perfectly. Low humidity can be the cause of your drooping leaves and make them seem dried out as well. You have to find a way to raise the humidity more in your growroom. The tiny humidifier must be replaced with a larger one for sure.
You can also put a pot of water on a nearby heater and mist the plants often if it’s not a very large space. If you have a large growroom (bigger than 8’ x 8’), you may want to consider investing in an evaporative cooler AKA swamp cooler that cools and moistens air. Once you get your humidity to a preferable 50 percent or so, you’ll see signs of healthier growth.
