Plants will start budding soon and I need help with HUMIDITY!!

skaterdude0696 · Apr 13, 2016

Hey everyone,

I am growing in a very small tent only 2ft x 2ft x 4ft. During the day my humidity avgs. at 40% while at night gets upwards of 65 - 70%.

Being such a small space I figured it wouldn't be hard but during the day run a ac unit (not at night b/c temps drop too low) and there is a dehumidifier in there and two fans so why is the humidity still so high??

I'm a newbie so if I'm doing something wrong please HELP!! I just don't want bud rot to form as the plants get dense.

Any information will help!

Thanks!

Does your a/c not adjust to a cannabis friendly temp?

its impossible to maintain a stable environment in a small tent. high humidity is never an issue provided you have good air circulation. plants need air circulation around the leaves to transpire which pulls nutrients up into your plant so it grows. good luck but i suspect mom will find it

The ac is fine during the day cycle but at night it just gets too cold withought the lights heating it (63-70*F) if I leave it running, although it brings the humidity down...

Well I live in a high humidity location and it has great air circulation breezy when I walk in. I just suspect that the hot humid air in the room being circulated doesn't drop the humidity much?

That temp range is actually pretty picture perfect for the night cycle...problem solved

My tent is 20" W x 36" L x 60"H. I am able to maintain extremely stable conditions. Day temp is 79 night temp is 66, rh is in 35-45% range and I have plenty of air circulation. I don't personally think maintaining a stable environment is quite that impossible. Just Sayin'

I second this. I don't see any problems with those temps at all.

As I was told by a very experienced grower,"you and your girls are going to have to learn how to get along"
Which really means do whatever makes her happy... and that has always been the case.

Sweet Thanks for the fast reply's everyone! I've heard more than 10*F difference per day could be bad?

I guess It's not true?

Thanks!

To some extant this is true...but as long as they stay above 60 degrees or thereabouts and below 85 degrees or thereabouts you are golden. I have even stretched day temps to 88 and 89,,,no issues.

Thanks this is perfect information I will leave the the AC on overnight now to reduce humidity!!
I'm glad to have finally figured this out especially a little over week 2 of flower hoping they'll start budding soon!!

I'll post if anything else happens hopefully my first grow will turn out good!!

Again!! Thanks everyone!

You got a slight phosphorous deficiency and what looks like a slight calcium deficiency or heaven forfend>>spider mites.take a look under the leaves and see if you got those.

Before upping or lowering nutrients...check your ph levels, read the info in the links, and use the search feature here on RIU...draw your own conclusions.
