Sealed Grow Room and RH%

[Mont@n@]

Hi this is my first time building a sealed room and I have a several questions. I know sealed means no in or out take so what I have been reading is that in a sealed room most of the indoor growers are having trouble with RH% during lights off.
My room is 6x5x8 with a 600w hps and a diy aeroponic system very similar to a aeroflo 36. Its going to be built in my garage. With a ½ ton ac and a minigen co2 generator.

Do I need a dehumidifier for lights on? if not

I know plants they dont use co2 during lights off so im thinking of using a 6in motorized damper on a passive intake/exhaust to get all the high Humidity out during lights off. These dampers are going to be controlled by my growtronix system.

any constructive criticism is welcome

In florida bro?
Whats the RH in your area?
I mean, all the 90%Rh air movement in the world is still 90%

outside is between 70-90 but normally my passive intake brings dry air from inside the house. my actual house is around 35-45%

ps. all my grows they have been done in a cold weather state so this hot weather is new to me.

On the SpaceCoast myself;
You will absolutely need a dehuey come lights off. The only time i need dehumidifying during lights on is when it's cold enough outside that the AC barely runs.
You can go the passive intake route but and save $$$ on your juice bill but a dehuey is what most all of us Florida growers MANDATORY.

Thank you for your answer

asslover you hit the nail many thanks

i guess i have to under sized my hood fan or run bare bulbs for winter just to keep the ac running.

Monty,
Check the "calculating AC" sticky in this section. I think you'll need more. Best to always have excess capacity [within reason]. Good luck. -granger
