Struggling with humidity advice please

[Cheddar1991]

Hi I'm currently in week 4 of flower I have gelato,pineapple chunk and blueberry. I have 3 fans running and extractor fan and just popped a dehumidifier in there to try help bring it down. RH is averaging 72% temp is averaging 28c lights on. The weather won't last long tho so be back down to 25c in the tent. How would I be able to get the humidity down more?

Also with tthe popcorn/larf bits can I still trim them off or will it stress them too much? Should I defoliate some if so how much? Sorry realivity new to growing.

Thanks

28c and 72% is not terrible assuming the space is clean, you are around VPD numbers for early flower. Hopefully the dehu helps to drop your rh some without raising the temps too much. As far as defoliating, you may want to check the view from underneath and clean up anything not getting good light as it will not usually turn into anything desirable and removing some of the vegetation not getting light should also help with airflow around the plants. Where is your hygrometer in the tent? Is that a ground level or canopy level reading? My concern would be micro climates due to how tight your girls are packed in there so lots of airflow will be key until you get numbers under control

If you have an ac you can run it on23- 24 degrees c and it will dry out the room the dehumidifier should help but I would not worry about it that much most plants like it humid. If you are really concerned try to make sure the air get circulation in the whole room and add a second dehumidifier outside the tent. So the air going in is less humid as well. For the trim strip them down it will stress them a bit but not bad I am pretty ruthless in how I strip my plants see pictures. Day 40ish of flower. Everything below the net I strip off I do about half on day ten of flower then the rest on day 30ish but I leave no small buds at all if I can help it. I hope it helps and have a great day.

This morning I was having an issue getting the humidity down in my flower room to below 60%. Even with the door open and rh outside the flower room at 50% it wouldn’t drop. After 5 minutes of head scratching I decided to move the sensor probe out from under the leaf that was shading it. Behold my rh dropped like a rock to 50%. It wasn’t the shade causing the higher rh reading but rather the plant was transpiring on the probe.

Point being the sensor location is key to an accurate reading. Where is yours located?

I have a hygro on the floor and I have a Bluetooth gove at canopy level

They look good mate. I'd be to worried taking that many lol and they survive hole way through ok with not that many fan leaves ? So defoliation won't cause hermie?

Thanks for info

The one of the floor is shaded and reading 78% I have the hole hygrometer in there and the gove meter is reading 72ish at canopy level. I'll move the floor one and see if it drops.

Thanks for info I'll post pic of gove screenshot

What’s the ambient rh outside of the grow environment?

69% I'm in the loft

That’s the contributing factor to your issue. Only solution is a dehumidifier.
