*Humidity is gonna kill my buds again!

[speeka]

heat will not cause your relative humidity to rise, cold will , if your intake to tent at lights out is cold air then you will get high RH. If you vent too quickly & the air in tent doesn't get the chance to heat up, you will get high RH. Also if you are venting to the same room the tent is contained in, you will cause damage to the room itself , the especially electrics & wood.

You will get also get high RH @ lights on if the air you intake is colder than approx 5- 10c.

Damage to the wood and electric's can you explain this in more detail i'm curious as to what effect it may have?

Thanks KB

i have night time temps at 19 c ?

should i reduce this more????

Hey Kathleenbilly,

Sorry to hear about your lost from the bud rot. Any devastating like that is a well learned lesson though. Your night temp is perfect as long as the humidity doesnt go soaring, you shall be fine. I was in a tent too and had the same problem I just increased my out-take. Any lower then 19c and high then 43% humidity will cause problems for you my friend.

Well as i said above, if you vent indoor's & you have colder air outside, you will cause condensation on the inside of the room. Ie winter months. This condensation will soak through any wood you have in the room & eventually make it mold over & rot. In worse case, you will have you roof pay you an unwelcome visit, when it try's to kill you when it collapses from having rotten timber's.
Condensation & electricity, as you can imagine are not 2 things you want together.
LoL a few years back i was scared to vent outside as my carbon filter was coming to the end of its life, not wanting my neighbors to peg on to what i was doing i vented inside instead, well imagine my surprise when 2 days later whilst mixing up some Nutrient's I realised it was raining inside the room!
The condensation was falling from the ceiling like rain!

hey, i had a question
i'm still kinda new at this
I'm using co2 with a dehumidifier
i'm doing rockwool 6 inch hugo and my dehumidifier is set on 50% night and day
wouldn't the dehumidifier suck out all the water from the rockwool when it's sleeping ??
I heard that i'm only suppose to feed them 2x a day, every 4hrs ? or 3x a day ??
or would i just have to feed it (ebb & flow) before the lights come on ??
TIA
