Does anyone use a dehumidifier during flower?

I use a dehumidifier during the night time while in flower to prevent bud rot.
Obviously to keep the humidity low........the humidity goes up when the lights go out.

I use a dehumidifier when needed. I benefit from lower humidity from using one vs not having lower humidity when not using one.

I use one more often than not during winter.
during winter it adds heat at only 220w of power and dries the air if the humidity is too high for my liking.
I like to keep my RH during flower below 55%.

using the dehumidifier PLUS the inline fan would be redundant, right? would it be better or cheaper to run the inline 24/7 instead of the dehum?

you always need to recycle the air regardless of whether you are using a deheuy or not. Even if not for humidity control, just replenishing co2.

so fan on, 24/7?

Yep. Unless you have it set up with a controller, you leave your vent fan on 24/7. How much you will need to use a dehumidifier really comes down to the conditions at your grow site-# of plants, climate, time of year, any fish tanks in the house, # of people/dogs in the house, all affect the RH levels inside a sealed house/room. I run my dehumidifier 24/7 at full blast all winter long, to keep my rh at 50-55%. I find that a good sweet spot to grow in and I don't chase VPD. Once it's warm enough to open your windows, you'll find your RH going up and down a lot depending on the RH outdoors-it can get quite low in some locations and during some times of year, so you will definitely adjust how often you run it depending on the time of year. You may find you also need a humidifier during the summer, it just depends. IF you do buy a dehumidifer, don't get one of the little thermo-electric closet models-you need a proper 250-500 watt (depending on size) dehumidifier with compressors-check out the 20-30 pint models. Most of those will need to be emptied 3-5 times per 24 hours in a high RH environment, but some you can set up to drain continuously into your shower or someplace else with a little built in tube. Good luck to you! Be sure you have several accurate hygrometers that match each other's readings too.

Utilising the dehuey in a lung room is best that way you control the lung room RH and Temp and this draws into the grow.
for example.
you have a tent setup in a bedroom. Your exhaust is temperature/RH controlled (doesn’t have to be both) and exhaust away from the bedroom.
You control the bedroom Temp/RH by using the dehuey so that the intake ports take in the lung room air.

I use a dehumidifier inside my tent dehumidifiers don't work so well in cool temps they're much more efficient inside the tent where it's warm and have more impact on my humidity.
My fan also runs 24hrs in the summer it doesn't switch to thermostatic until it gets down to 20c
I face the dehumidifier towards the wall/fans not towards the plants that'll cause windburn.

I just want to use the thing to suck the trichomes out of the bud during flower. I have a $100 dehumidifier, because I'm growing in a closet and I thought I might need one to control humidity this summer, as it got awfully hot last year. That has not been the case this summer, although, temperatures do get pretty hot in that closet (+31C). Have you noticed more or less trichomes from not using a dehum. vs when you do use it?

What difference would a dehumidifier have on trichome production? A dehumidifier removes humidity from the air, not increase or decrease trichome production.

You can but it might only knock the humidity down a few percent, how big is your tent, and how big is the inline fan? 4in usually do between 250 and 305 cf/m 6in do about 150 to 200cf/min more. If your tent is maxed out for plants my guess is you're watering alot and thats gonna significantly raise rh

This extreme dryness will encourage the buds to seal and protect themselves with additional resin (in other words, a sparkling outer layer of THC-heavy trichomes)."

I’ll pass on any of that advice, thanks.

I would steer clear of sites like that and read up on threads on this site that are similar to your issue or issues then if you can’t find anything close to it ask questions in the newbie section and there are some very knowledgeable folks here who would be glad to help

the only reason a dehumidifier might enhance trichome production is through the stress it can produce...not the optimal way to enhance anything...you would do much better dialing in your room for the best balance between humidity, temperature, and available light...and feeding them appropriately.7 Ways to Improve Cannabis Bud Quality | Grow Weed Easy
