i have a humidity prob in a sealed room. contains: four 1000W hps, two 8" inline fans to cool lights, 2 can filters for lights located outside the room as to not waste co2, 50lb co2 hooked to titan reg which is hooked to XGC-1e w/fuzzy (1400 ppm), four 4x4 trays w/ four 25 gal reservoirs, 50 pint dehumidifier set to 35% which never stops running, a 25,000 btu window mounted ac. reservoirs are covered. is there anything im missing? the room has no intake or exhaust (unlike my veg) because it is running co2. if only i can get humidity down it would be picture perfect. humidity is 40's to 50's but there has been times that i see in the 60's or maybe even 70's. this was before i rearranged things. its usually in 40's to 50's though. my ac being a little crooked might be spitting humidity back in once it stops cooling (need to fix this today). anyone have sealed room experience? thanks a bunch

Get another fan, a cheap oscillating type, move the air in the room I advise. Prevents walls from sweating badly and mildew forming, I cut back my humidity by moving adjusting my plants and making sure I have good air flow between the plants. Since your lights are already cooled, moving air in your room is the best and cheapest option to cut back humidity, and besides the leaves moving a bit helps light dispersion.

Ya i have 4 wall mounted 11' oscillating fans. in that bedroom. i am thinking about maybe adding one more somewhere. i also crop my flowering plants as to let air through to minimize risk of mold (just some large fan leaves and leaves blocking air flow). Id post pics but i dont really like to

Get a dehum $200 and say by to mold. make sure you have your temps in check because mites love high temps low humidity

The only thing you didnt touch on was how your tables are set up. I do ebb and flow on two 8x4 tables in a 12x8x8 sealed room. The tables are covered to prevent light from entering and growing algae. my humidity stays around 45 to 55% w/ lights on and climbs up when lights go off. But dehumidifer goes on when the lights do and in about 30 min the humidity drops from 65-70% back to 45-50.

for safety i would do a hose a bucket i found keep my humidity at night vital for the strain i was running (og kush). if i didnt run dehum all the time there would be this lingering wet damp smell. I figure that was asking for troulbe
