hi folks.

RH is very high where i live.it is now70- 80 % and RH may be over 85% in summers. i live in a coast.

i have 120cm X 120cm X 200 cm homebox XL tent,9 fem plants in it and all of them is 32 days old. i just transplanted them 11 L pots and as soon as they root,i will go to flowering period.

and so RH is my tent is between 60 -70 % in daytime and 70-85 % is at nights.

i have 1 extractor for now my current air flow :

inside of tent > carbon filter > cooltube > extractor > outside of house

i have an extractor and 2 oscilation fans work 24 hours for now.i will buy an extractor more for active intake to bring fresh air from outisde of house for hot summer months.

so my air flow will be like that in 2 weeks when i buy a new extractor for active intake :

extractor 1 : outisde of house > extractor > inside of tent
extractor 2 inside of tent > carb filter > cooltube > extractor > outside of house


and my questions:

1) there is too much air circulation,how can a dehumidifier do its work ? 2 extractor is always working.will dehumidifier really work for me ?

2 ) my tent is full with 9 girls.if i buy a dehumidifier ,i will have to get rid of 1 plant to put dehumidifier in my tent :cry: . is there another way to do that without losing my 1 plant ?

3 ) 10 litre or 20 litre dehumidifer ,which one should i buy ? 20 litre dehumidifiers are expensive at twice than 10 litre ones . is 10 litre enough for me ?

4 ) fortunately , i cant see any powerdered mildew for now. my girls are 32 days of vegging and i will pass flowering as soon as they root.as i said, RH is between 60 - 70 % and more at nights.when that high humidity will begin a serios problem for my plants,when they have bud in flowering ?or is high RH always a risk for plants ?

i am asking this because i want to postpone to buy dehumidifier as possibly as i can.

thanks .
 
Seems like you have a small problem with humidity huh?? lol The only thing I can think of for you to do is install a dehymid, you could always install a carbon filter, or a filter that will catch and drain water moisture but that may limit your intake air greatly. Other than the "dmid" I dont see any other choice but to smoke more in the room.

You have no choice, and you need it by week 5 or 6 if your use hid lighting happy growing bro.
 
you need it bro if your using hid lighting in a small area youll need it before week 6, if your not using hid lights then looks like you need it any way with your current conditions.

Happy growing
 
humidity = quantity
no humidity= quality
you kinda whant high humidity during the first few weeks to make large budz but you whant to decrease the humidity levels and temp especially at night.

Happy growing.:joint:
 
with high humidity you will have bud rot PH has nothing on straight to much humidity and you get bud rot, which sucks way more bro.
Happy Growing.
