Week 3 of flowering, humidity 80%

[organicfreak]

make sure u use a filter though will clog fan

 

[organicfreak]

also has a tube for drainage

 

[organicfreak]

continuall drainage i mean so no buckets

 

[organicfreak]

lol no emptying buckets

 

[organicfreak]

if your were slick you could use electric dampers and different humididstats and control diff humidity in difernt rooms..

but then that would defeat the purpose of trying to get his post count up so he can pm or buy seeds!!

i bet enuff air movement and you could get away with higher rh

im not familiar with VPD but wouldnt lower rh be better for growth according to cohesion-tension theory?

Not exactly. VPD has to do with temperature and RH and how it affects transpiration and transpiration rates. The sweet spot for my girls is 80F + 70%RH.

A VPD calculator, and don't ask me what the numbers mean, I just know that we're looking for a range. VPD deserves a thread of its own and I think there was one here a while ago.

organicfreak its against the rules to post like you have in this thread, if you keep that up your likely to get your post count reset or banned

you may not have known and thats why I mention this

santfee max is good

phonix is another 1

look for company thatt mak dehumidifiers for house floods real bad ass...

2000$ but you can do several rooms

make sure u use a filter though will clog fan

also has a tube for drainage

not to mention its rude

sorry bout the threadjack

Constant 80% RH, Very cold and damp here.
Got a dehumitifyer and it had it at 40% very quickly.

Cold and damp I already assumed. I was more asking for a number to try and get you into a good range. Just trying to get you started on the right foot.

It is all relative... lol.

A VPD calculator, and don't ask me what the numbers mean,

Great links, Those Aussies got things dialed in so many ways!

The numbers something like this.

100% rh exerts a vapor pressure of 24 torr.
When you have warm days and low relative humidity this creates a pressure deficit. Which means less pressure on the plant. Whenever surrounding vapour pressure is less than 24 torr then you have a "vapor pressure deficit".

Now you can go back to ignoring that number lol :)

you may not have known and thats why I mention this

ow yeah my bad, sometimes is education rather than user error. (or impatience)

forgot about that 10second delay waiting for approval thing..
