Temperature and venting humidity dilemma

[TedeBoy]

They are flowering.
My tent is in my garage. The air temp in the garage gets in the low 60F's at night.
I need the air moved since it gets 70%+ rH in the tent and they are flowering.

I have the exhaust fan on a thermostat I mess with to keep it in the mid 70F range but to do this my tent climbs in humidity. To bring the rH down my tent temps drop into the mid to high 60F's.

This happens for a few hours at night (lights are on) only.

Which do I choose...higher temps and higher humidity or lower humidity and lower temps at this stage?

What kind of light? You need to get the humidity down to at least 60% and even 50%.

Even a regular light bulb with the right light spectrum could add some heat or cheap small heater on a timer. Put the heater on the lowest setting with a timer to kick on and off every 15 or 30 minutes.

Sun Systems 315W LEC.
Most of the time it's at 50-60%.
It's those times it's not that are worrisome but then again I'm a bit if a worry wart...lol.
Thanks for the feedback.

Considered a dehumidifier? I feel like that's what you're looking for. Whether it be an electronic one or the granules you can get?

Good suggestion. He can get some cheap Damp Rid granules or maybe those small $29 to 49 mini humidifiers.

LEC? Nice. No wonder those plants looks so good. Being a worry wart is a good thing. I have told people that the best growers would be someone who is like a grandmother who dotes on or babies the plants. You got to check them, watch them and tweak things to make sure they are getting good care.

This is my second grow with this light in my 3x3 Gorilla tent. 6 Mephisto autoflowers.
Next time 4 plants max...lol.

They do respond well to this LEC.

Oh also...I have a fan running under the canopy blowing up through it.

Nice. Looks like the fan idea is helping. Looks great. Dude - you need a bigger tent.

My dream would be PV panels on the roof and a dedicated grow room in my house.

I also have a tent in my garage. Here in the NW, having a dehumidifier in the garage is absolutely worth the investment and cost of electricity. My garage is finished with drywall so there's zero airflow with the windows closed.
A 50 pint unit that drains into a 5 gallon bucket works perfect. Humidity still spikes when it's raining & wet cars pull into the garage, but the dehumidifier eventually catches up. I run it in "continuous" mode during rainy season and empty the bucket every day.

I go with lower humidity over higher temps just to stay away from bud rot my flowers see low 50's at night and don't seem to mind at all

Does anyone recommend any dehumidifiers? I got a 500ml mini one for my room as well as some granules. Is there a way to work out what would be appropriate, similar to working out extraction fans?

P.s. Not meaning to hi jack the thread but just thought it would be useful for OP

I tried clear poly carbonate roof panels. Very tricky to get it to work right including the temp. The house/bldg. has to be set up to catch the sun during all different seasons. I think with PV you mean solar aka photo voltic.

DIY COB LEDs are more expensive but you get lower energy usage. Not as cheap as free sun but close. LECs are pretty close.
