Figured it out, I think. It's when the temp is right between 76.9 and 77.0. It is for some reason not switching the zero. Once it's down below 76.9, it functions accordingly. It did this at every whole degree increment I've checked.
Hi moe,I have a water softener and RO systems.
The RO filters seem to last forever. My out of the RO filter PPM is less than 20.
Calcium and magnesium are the two main minerals that get removed in RO so you want to add that into your nutrient mix.
Yes plants will add humidity to the tent but that usually spikes a few hours after feeding. I'm just guessing from anecdotal experience but I would venture to say plant presence will increase humidity in the tent around 10%. What size humidifier to you have? What is the ambient climate like in your area on average?
I have a levoit 6L ultrasonic humidifier, but would like to pre-order AC's T9. We'll see. The tent is in a small room that stays around 70-74 degrees most of the time. The tents intake is ducted into a small hallway where I have a window AC that has been keeping the temps in the mid to low 60's.
Alot of ppl use negative pressure to keep smells from leaking out the room, its not necessarily beneficial for the plants from what ive heard. Im sure it was bruce bugbee who said they're may even be bad for the plants over time but thats only if its too strong.
I do run the exhaust constantly so there's at least SOME consistent airflow. The intake fan just has too much power, even on low, to keep negative pressure AND keep the humidity above 60%. It drops to 40% when keeping the pressure negative.
AFAIUI, it's not really NECESSARY in regards to the actual plant biology. It's more about keeping odor out of places you don't want it. What you don't want is TOO MUCH negative air pressure. As long as your tents walls aren't rigidly sucked in you should be fine. My tent walls slightly suck in but I can easily move them back and forth so what you want is SLIGHT negative pressure. Just enough so nothing really escapes.
Agreed! That's why I sprung for the T3. I could have gone the controller route also but I like that the T3 will taper the humidity it's producing so that it's not all or nothing once it goes out of range. I like the hose attachment that allows me to point it at a particular area or just generally pump it in with the unit outside of the tent if I want more floor space. I may pick up one of the UIS outlet controllers for a small heater if I can't control my lights off temps but for now I'm able to keep it within a 10* temp swing.
Oh for sure. Don't get me wrong, AC's cloudforge series look freaking awesome and I can see why they're sold out. I'd like to get one pre-ordered before May because I feel as though they'll sell out quickly. I'm gonna need some help keeping my rH in a suitable range when the summer months hit. That'll be about the time my lights are on blast and I assume the fan will we working a lot harder than it is now.
As long as you got control of the lung room, outside ambient weather shouldn't have much effect.
Have you tried putting a bug screen or mosquito net on it? I had a similar problem and just layered 3 sheets of mosquito net with rubber bands onto the extractor fan. Seemed to slow my down by a quarter then i jist put a bit of duct tape to restrict a lil more airflow
I didn't see this above when I made my post ... It's exactly what I was trying to say about the outlet plugs. They work very well and might be one of the stronger points of the ACI controller.
It's only a 5x5 for my first grow but for the price, the T9 is a badass humidifier. The T7 is great, I'm sure, but that T9 would probably keep up if the exhaust needs to run at 10 when the light runs at 100% for flower. I can't keep the humidity above 40% with the temps around 77 and light at max output. Maybe the plant itself can cover the extra 10-15% I'd like to keep it at.
