PLEASE HELP...im ready to pull my hair out! HUMIDITY...

[SeaLevelGrower]

I am not sure why I am having such a big problem with keeping ANY humidity in my grow box. I just completely re-built it and still no humidity. Here is what I have:
1) 4' wide x 2' deep x 5' tall box in garage
2) lined with panda paper
3) 400W HPS approx. 18" from canopy...glass on hood soon to come!
4) 6 plants vegging in 12 inch round 3 gallon pots filled with FF soil
5) 2 speed circulating fan in box...
6) active 8" exhaust out the top of box...restricted massively
7) 2 4" holes on bottom right
8) 1 4" x 8" hole on bottom left
9) large room humidifier in bottom right of box
10) numerous soaked sponges in open areas

I live a block from the ocean...ambient temp in garage is about 68 degrees.

CURRENT TEMP IN BOX: 81 DEGREES
CURRENT HUMIDITY IN BOX: 19%

Im not sure what other info might be relevent....please please help me with this issue! Before re-building this box, I had built a small frame and wrapped it in clear plastic to create a humidity dome...but the plants have out grown this contraption and I am now at a loss!

Thank you in advance!

Have you tried placing a 5 gallon bucket of water in the grow room? That should bring up your humidity. Doesn't necessarily have to be a bucket, but something that you can put a fair amount of water in.

WELL....the humidifier takes up the only open space...its either a bucket of water...or the humidifier. I did have a tray of water before I got the humidifier...not much help!

[Italiano715]

Just take the bucket and place it underneath your lights with your plants. I bet that will help. I'm sure you can squeeze a little something else in there. :jointsmile:

maybe it will improve when you get your cover glass on your hood ?? ... by the way, ALWAYS run the tempered glass cover, with high-pressure lamps, for safety ... it is true, you do lose a few lumens with the glass, but it is minimal, and I'd rather have my eyesight ... for instance, an invisible crack in a metal halide lamp, emits dangerous UV radiation, harmful to eyes and skin ... good luck :thumbsup:

Have you only checked it with one humidity divice? Maybe you have a bad one. Maybe something to check.

If possible you should add an aircondition line to the box.. That will raise it some.:thumbsup:

When cold air meets hot air you get condensation that in turn would raise humidity if exhaust were backed down.. Then there would be a heat issue,even with the air.
