Recommendation to get rh down?
DomForesterstarted grow question 8d ago
On rainy days (of which there are plenty around here) I struggle to keep rh in check, especially during lights off. Ok-ish for now but will be a problem when buds get bigger. Tried a small&cheap humidifier before but doesnt do much. Any recommendations that dont cost an arm&leg?

I use a proper dehumidifier from a German company that cost me around €90-100 and it works really well. Normally I just keep it in the same room as the tent, outside the tent, and it does a really good job keeping the RH under control, even when it’s humid outside.
Sometimes I open the tent and place the dehumidifier directly in front of it for a while to bring the RH down faster. I also use the same unit in my bathroom, so it’s not something I bought just for growing.
I wouldn’t bother with the tiny cheap dehumidifiers though, they usually don’t remove enough water to make much of a difference. If you want, I can tell you the brand and model I use, but in the end it depends on the size of your room or how many l/24h you want it to remove

I would add another small fan that is on 24/7. You may need a small dehumidifier.

Yeah, you want between 40-60% during flower. Cutting corners to save a buck will cost you come harvest. You save a boat load of money compared to street cost and dispensary cost for weed. One plants harvest in my tent would cost around 0-,200. Spend the money and get a good dehumidifier or save for it. Until I finally purchased all the necessary equipment over a couple of years my grows were weak. It's not much when you consider the savings but a good chunk to have at one time. I can't afford to have an unsuccessful grow but it took several years and experience to achieve this. I get close to a pound a year with two grows. More than enough for the two of us. I have 0 invested and each grow cost around -0 a plant but well worth it.
Good Luck

Eyy bro,
It depends on how much we’re willing to spend. I think a good-condition used dehumidifier would also be a great solution. I bought one five years ago for €70, and it still works perfectly. It’s also excellent for dehumidifying a room where clothes are being dried.

After reading your prob. , I wondered if you filled up all the amount of space…. 😊
After looking your diary, I knew I was wondering right …
Bro, growing a dense canopy implies a dehumidifier with a compressor in the room outside the tent and a humidity controller set on your exhaust speed fan. And this cost money.
Or you can manifold palm tree style, but require a few years of experience in cannabis culture :

Boa tarde, isso pode ser um problema na flora... Mas se aumentar a circulação de ar, deve conseguir estabilizar os valores e até baixar. O que pode fazer também é reduzir a area de transpiração, ou seja, fazer uma desfolhação. Se optar por isso está na altura certa, 3 semanas de flora. Pode remover até 30% das folhas mais velhas...

A properly size dehum is the only choice for something that exhaust or schedule can't mitigate. if ambient rh is high, exhausting 1000% won't do anything. the bigger that canopy gets, the more moisture it releases.
The one thing that can help after lights go out is to maintain a similar temperature. you can eliminate that effect. (ceteris paribus, a temp drop = rh rise)
