What would be the problem???

Okay,,, so im preparing to do a sealed co2 enriched dwc grow in a 5x5 tent... I'm gonna run 1000w on(hopefully) 8 buckets if not 6... The 1000 will be in a cool tube pulled by a 440cfm... Tent will be scrubbed with an additional 440cfm... Ordered a bladeless fan for constant air movemnt(thinking of putting the scrubber on a 1min/on-20min/off cycle) Ambient room temperature will range from 70-76 degrees... Regulator and light fan will be controlled by a sentinel chhc-4... This will be my first attempt at co2 enrichment and I'm trying to alleviate any future issues... I guess my main concern is humidity,,, but i would like to know of any other issues that growers have had with this similar set-up... Also,,, should i get an inline for exhausting when lights are out???

am i posting in the wrong forum??? not one reply???

For when the lights are out many growers just leave a small fan on, circulate the air/c02, as plants do breathe in the dark too

How are you going to deal with humidity? A dehuey ads heat, which then requires an AC. The old school way would be to turn off venting, enrich the air and hold it until either the temp or humidity go over a set threshold then cycle in fresh air thats cooler and dryer, Then start the process over.

I use Co2, and I have a Co2 ppm meter that tells how much Co2 is in the room when it's emitting. If you're going to use Co2, you should invest in a Co2 meter.

Im using an environment controller... co2 will be controlled and monitored...

you waited a whole 2 hours and 31 minutes before this?

so your saying without a doubt i will have humidity problems with a 10 degree difference in inside/outside temps???

Can't say what your temp differential will be but yes, with no air exchange your humidity will be too high in a matter of hours. Adding a dehumidifier will create heat that will have to be dealt with. If you can control the heat of your 1k in that tent without AC, You might be better off using the semi sealed "Hold the Co2 in the tent until it gets to hot or humid and then recycle" method.

Will your controller run a dehu? If so you could vent instead of dehu.
