Dutch Passion DP Auto Ultimate & Think Different outdoor grow (30L Airpots)

Lovely looking grow and those pots are HUGE. Sorry you had some bud rot but I'm sure a good extractor fan to keep the humidity down would sort that problem in the future. My last Auto Ultimate took 95 days.

Thanks TaNg! (LOVE your grows btw). Yeah those pots were a bit bigger than expected, but I don't I am getting their full potential yet. I have to dial in all of the other factors.

I definitely need a different extraction fan (+ carbon filter) as the one I have now is a temporary fix. I really need a quiet one though. I was looking at the following fan: http://www.solerpalau.com/td-350-125-silent-ecowatt.html

What cfm rating is your 100mm fan?
 
Cheers bro,here's the fans I use and I would recommend Rhino Pro carbon filters.

Allrighty, did you post a link (I don't see anything)?

Do you have any experience with Phat carbon filters?

Lol sorry bro stoner moment....here's the link. Amazon product

Not use Phat myself but they are held in high regard an up there with Rhino. I'm trying a Red Scorpian at the moment but it's only been in a few months, is a little cheaper than the Rhino which can last 12-18 months so if this lasts 12 months I will be recommending it. http://www.greenstreamhydroponics.c...ters/red-scorpion-carbon-filter/prod_803.html

Hahaha, been there, done that. No worries mate.

Thanks for the links and the recommendations. That fan looks OK, not to expensive luckily :)
 
ive had one runing almost non stop for three years.

Awesome. What humidity does it keep your grow room @ without using a dehumidifier?
Does your dehumidifier produce warm air?

I've decide to go for the Manrose MF125S because I like to have the slightly higher displacement option (310m3/h). I think I'm going to pair it with a Phat 425m3 Carbon Filter. I will probably get them at the end of the month with my next paycheck.

Humidity varies depending on outside RH and how much water your plants are transpiring, I try to keep it between 35-45% which it sits a most of the time to be honest but it can go higher in the right conditions and then I pop on the dehumidifier why does kick out some heat but it need heat to work.

I hope I can keep my humidity around that % with the new extraction fan. That would be a big relief. This morning before I left for work it was like a sauna in my tent @ 28°C and 86% r.h :eek1:
