marine apps don't work in grow spaces. they eat more power than the rest of your grow, add piles of heat that need to be dealt with, and require adding chemical dessicant.

similar types are used here in livestock barns.


edit : i would not be afraid of a dehum that uses a refrigerant. my pops worked in hvac. i know how well that type of system works.

What dehumidifier do u run with?

I don't. I have gradually adapted to using the door of the room that the tent is in. The door of the tent first for controlling the temperature and and humidity. If the numbers are still not right then I might have to use the door between the room and the rest of the basement.

All I know is that I have not had to use the dehumidifier or a space heater since the middle of 2021. I let the heating and cooling system for the house do what it is supposed to do for the basement and the benefits extend into the room.

Il post a wee shot, all developing nicely, and no sign of mold. Have 2 fans running. Think I may be OK until drying starts.. Then I will really need a dehumidifier that can just sit in the tent and keep the RH at 60..

Or read the thread on using a household refrigerator for the low and slow drying stage. It is a long thread but reading through it is cheaper than buying a dehumidifier..

I'm in 2 minds what to do now, it's gonna be at least 2 weeks before I get my money back.. Had a read over the instructions again l, any space above 4m2, my bedroom is more than that,. It's says to operate it in a ventilated room. I have my room window open all the time it wud be in use. This is the area of my bedroom where passive intake is, ya think if I placed it around here but away the 42 inches it would be OK and wud work?

If afraid to try it, cuz they said if it was used they wudnt refunded me.

it won't cause an issue but you should solve for proper ventilation first. with a proper set up i doubt you'd need it. you are fighting yourself by dumping air in to another part of the house. a proper ventilation system is under a hundred bucks, black mold repair can cost more than the house value if you get it. i've seen houses condemned and demolished over it.

I've got the ac infinity 4in with the 69 controller. I've got the piping running into another room yes, but it has 3 large windows open that pull the air out very quickly.. Its always cool in thos room with the windows open.

I'm gonna get another ac infinity inline fan to pull air into the tent directly from the window. But the reason why I didn't buy this product now instead of a dehumidifier was because here in Ireland the normal rh this time of year is high.. In the 80s! So figured not much point bringing that air into the tent without lowering the rh of it first. Have I got that wrong?

closed systems offer far better control. it's not hard to build a window box and pump air direct to outdoor. it will solve a lot of things you probably don't realize you have going on. it's always the first place i go before adding ac or dehum, it's also the cheapest.

the infinity fan can be run on heat control or rh control. it may negate the expense of the dehum. i still think the dehum is a good idea. i'm impressed with anyone who can grow in high rh, it's much harder than low.

i would run the dehum near the tent, but outside of it, without the windows open. it'll take the load out of the intake air, giving the extractor a chance to do the rest. the extractor only has to work with the plant respiration then. if it's still too heavy, i'd move the dehum inside the tent and see.

Yeah the rh setting on the 69 work well keeping the humidity in check during veg.. But once I got into deep veg and the extra plants growth put on. Even the ac on setting 10 still won't get the rh below 70..it will get it to about 72, that with dehumidifier I've in the tent now.. It doesn't have a humidistat tho. It still helps some. Without it rh was in the 80s..iz capping my pants.

The instructions says tho to run it in a ventilated room, and not run it unattended. That's what has me worried, il be away from home for 9hrs a day! Maybe I'm over worrying, do app humidifiers say that in the safety section?

Would like to do the window box ventilation, but I can't because I live in a housing estate, windows at my same level all around me, a wooden sheet of ply with a pipe outlet would be way to obvious. To many nosey people around me, it's shit but better to be careful and not get caught and get all my equipment taken off me lol.

@Bill284 what you think Bill. I seen the fire you had. It certainly got my attention. Just curious what u think of this dehumidifier I got. I'm probably over worrying. Thanks for ur input

Not sure where you are.
Designed for grow tents it will work perfectly.
Save you a few quid.

Can't say for sure on the one you listed.
Doesn't look like a fire hazard, but neither did the bran new light that blew up on me.

everything craps out when you need it the most. typical stuff for a grower.

The instructions says tho to run it in a ventilated room, and not run it unattended. That's what has me worried, il be away from home for 9hrs a day! Maybe I'm over worrying, do app humidifiers say that in the safety section?

that's a standard legal caveat on all dehums, ac, heaters etc. you'll never get away from it. i've been waiting to see if it turns up on lighting.

the truth is that you have to use these things whether present or not. that's why they come with a controller, otherwise everything would just have an on/off switch.

space heaters are the number 1 cause of electrical fires in canada. most folk are home and present when they start.
i run one in my veg space safely on a thermostat. it's all gonna depend on your diligence and risk tolerance. i'm far more worried about the small space heater in the room i'm currently sitting in.


dehums and ac rarely cause a fire.

Would like to do the window box ventilation, but I can't because I live in a housing estate, windows at my same level all around me, a wooden sheet of ply with a pipe outlet would be way to obvious.

check out the window box builds. i have built several stealthy. otherwise i plan my spaces to tie in to existing ducts exiting outdoor. odour will build like crazy in an enclosed space, making your whole house smell wonderful for a much much greater period of time. neighbours will catch that far quicker than it being carried away.

we grew 200+ plants at a throw and it all was ventilated through a stealth window box in a semi urban neighbourhood.


we had a sheriff and rcmp show up on unrelated business, they stood 8ft from it and never noticed. you can do it correct if you want.

To many nosey people around me, it's shit but better to be careful and not get caught and get all my equipment taken off me lol.

it's all about scrubbing and moving air.

@Bill284 what you think Bill. I seen the fire you had. It certainly got my attention. Just curious what u think of this dehumidifier I got. I'm probably over worrying. Thanks for ur input

bill literally got burned by a substandard mfgr. brands and quality build are important.

Lol that's very true, we just never fricking know do we.. That's Cool, thanks. I might test it in the am and see how it go's.. Still not sure.. But there's not many other choices for me locally in the dehumidifier range.

 

[bluter]

just consider - nearly all large / efficient dehums use a refrigerant. even old ones. that fire caveat came in to effect in 2020 when the mfgrs were required to switch to a different refrigerant due to environment hazard.

you can get dessicant ones. but watch the heat. i think vivosun is a dessicant. they don't pull as much. anything small is usually dessicant. larger ones will actively condense, requiring refrigerant. i still like the big ones. i would keep it and make it work.

edit : we never had to recharge or do anything to our dehums on the bigger grow. we did replace some filters. they ran 8 yrs before we got shut. we did not have ambient high rh though, all the stuff we dealt with was plant respiration.

Just had a look at that Bill, It doesn't have a humidistat. I already have one that I think (cud be wrong) is of similar power. Its a budget one It, running it 24hr it only reduces the rh from low 80s to low 70s..with the ac extracting at speed 10 that gets it to 71 when the light are on. Slot of other ones are sold out in my area lol..

I'm still undecided what to to.. I'm thinking I might just test this one in the morning. If I can get it to lower the rh on the lung room to 40 which it says it can, surely in the tent with the passive intake it won't be far off. I'm in the final few weeks of flower so a tent eh of 50ish is the sweet spot I'd like to hit. Appreciate you weighting in..

 

[bluter]

you could also get two of the smaller ones. two in tandem are often greater than the sum of their parts. if one doesn't work or is struggling, two could be an easy fix.

maybe send the big one back and get one small one. can add another later.

i think the big one will pull enough for sure. it will depend on cost up front and cost to run for the best course.

The budget one I have in the tent now only draws 80w..which is not to bad. Interesting, It never occurred to me adding another smaller one might take it down a little bit more. If I cud get it to 55/60 I'd be well pleased. Ideally I'd like to control the rh in the tent. It's just which one to choose now. Have to stick to EU.. A see a few nice ones but they are all out of stock. Il keep checking and if I see, il drop it here to get some opinions.. Thanks for feedback..

thought i'd just toss this here for you if you decide to go the ventilation route or add it. it's a window box vent build from one of the mods.

Tales From The Krip!

Man look at you go. Your like Bob Villa of the pot world I prefer "The Marijuana McGuyver", but I'll take that! :thanks:

www.420magazine.com

he painted it to match the exterior of his building. it's similar to some of the stuff we've done in the past. with a little work it looks like a professional installation from the exterior, and the neighbours would never notice. just needs some creativity.

i've also used a mesh that made things look like a regular window in an unlit room. you can also modify window ac units, and have them remain fully functional while hiding the grow exhaust.

Hey Butler

Thanks for the extra info. I will at some point be doing something like this.. But smaller. Ye see, I live in the middle of a load of housing estates, we don't get warm weather here. It's not like US where these are common on houses. Literally not one house in my whole town has that in their window. Their just not needed.. Am not saying I wudnt like to do it, or it wudnt be a great addition. It wud just draw to much attention.

These are council houses. They do be about the area all the time doing maintenance etc, and I'd be wayy to paranoid it wud just draw attention.

I will do a smaller version, make a small box just the same height as 4inch duc that will work the same I think. My back windows are north facing, prevailing wind cuts right across my back garden from left to right. It's easy to air out my bedroom if I want. I will defo make it white like the guy said to blend in with my window sill. This way the intake will literally be inches away from the window, but people walking by won't be any the wiser.. Anyone who's nosey enough to be looking from their top window across the street will only see a white box sitting on my window sill.

Really appreciate the link, thanks ..

On the hunt for a dehumidifier I spoke to the frwo store I deal with, and they said they have one that I can put in a 4x4. It seems a little large, but I deal with this guy since I start so I do trust his judgement. Or maybe he just really wants the sale lol..

Actually had another great development today, after 2 weeks of wait for one of these plants to show me a Amber trichome.. Finally today seen the first very few on 1 plant.. I've literally been looking at empty clear heads for 2 weeks.. Surpried how long that can take.. Here the dehum thinking of getting
