What’s up guys back with another question on my first grow, so the last two or three days my plants have slowly developed this problem in the leaves where they are curling at the base. My room temp is a constant 80° with 30% humidity. I’m in az and in my cabinet it’s hard to keep humidity any higher then that. Is this a humidity problem or what am I missing? Maybe over watering? Thanks for any help dgc!
The humidity is too low.
Alrighty thanks brotha I appreciate your help alot man! Do you know of a humidifier that really pumps out that’s small for a cabinet?
Try to find a tankless humidifier. Small humidifiers with a tank run out fast and need constant attention.
What size cabinet? What’s your ventilation setup?
It’s a 2×4 footprint about 4 ft tall. I have a 4in inlet with fan coming in on bottom of the cabinet and one exhaust coming out of the top I think I had the fans running too high but I turned it down and it went up to 82 but the humidity is at 40 now. Will that be good or do I need to try for more
You want 50%-60% in veg and 40%-50% during flower for the happiest plants. Temps should typically be 75-80 F during lights on with temps about 5-10 degrees cooler at night.
It shouldn’t take a humidifier on full blast to keep it at 50%, but your exhaust is the key variable on that. If it’s running constantly then a humidifier is a waste of energy. It might be better to look into cooling the room the tent sits in to help with temps inside the tent and cycle the exhaust on a high point temperature with a controller. They’re cheap, under $50. I have a 2 gallon humidifier that lasts a week until I have to fill, but I use it during seedling/early veg. After that my exhale co2 bag is fully activated and adds enough humidity in the tent that I don’t need the humidifier anymore. I live in a dry area and don’t own nor do i need a dehumidifier so I have gone through the trials to get my humidity up. Co2 bag + cycled exhaust = no humidity problems for me.
Meant to mention I grow in a 4×4 tent.
I find that for small spaces, the outside tent environment helps control the inside by quite a bit. Not saying get the outside to 60° and 60%, but if you can get it to 70° and 40% you’ll have a much easier time getting the numbers you want inside the tent.
Alrighty so I weather stripped the doors and put locks on it where it locks and closes tight now but humidity is only up to 45%. I’m gonna get a co2 bag and see if that helps the humidity a little bit
The co2 bag activates in 30-45 days, keep in mind.
Hey guys so humidity has been at a steady 45 50 now so doing well on that part but looking for an ac unit to cool the room my cabinet is in to try and vent even less and get it up a bit more. Any good ac units that dont dehumidify?
An evaporative cooler might be a good option. Not sure the size of the room, but here is an example, I don’t own this product, but it has a 5 gallon tank.

If you don’t want to spend a lot there are a lot of DYI options.
I forgot about the swamp cooler usually used in very low humidity for cooling but can boost humidity and should cool a little. Google diy swamp cooler, some 5gal bucket designs and more.
