Dehumidifier Planning in Humid Thailand (Flowering Room)

[bk78]

I think that Playk328 didn't get that we already tried regular residential dehumidifiers and they didn't work. It's all depends on your situation. I tried 2 different top of the line 50 pint units and they hardly made a scratch in my humidity. The 50 pint unit gave me about 2.5 gallons of water every 24 hours and would not get below 60% humidity. Plus there was no place I could exhaust the hot air. It was basically worthless and cost almost $300 and only had a 1 year warranty.

At $1200, imo, the Quest 70 is totally worth it. Sucking out 6 gallons of water a day and getting the room humidity around 50% USING THE SAME AMOUNT OF WATTS as the residential 50 pint unit. If I let the hot exhaust air stay in the room I could probably hit 30% if I wanted to.

Plus, with the duct kit, you can duct the air wherever you want to and the 5 year warranty is awesome.

His little 30 pint unit works for him so in his opinion it should work for everyone. That's where he is mistaken, but I let him talk his talk without a response because it wasn't worth my time arguing about it.

Dude doesn’t even have plants or lights running in his room yet. He’s in for a surprise once the plants start to grow.

My humidity use to be more stable, until that flood.. Once that flood hit it's just never been the same in the basement.. Hence why we are bout to do a full gut to stud remodel of the whole house..

Ive almost got the wife on board with going ahead and adding a complete solar panel system to this upgrade, I keep tossing then number 20kw solar system to her, it's starting to stick.

I had no idea that plants transpire almost 97% or more of the water they drink. I looked all of this shit up once I started searching for a good dehumidifier. I couldn't believe that my bedroom was soaking up almost 10 gallons of water every fucking day.

I was like WTF is all the water going?!?! Was my central a/c taking it all up? My tents weren't moist on the insides and there was no water on the walls so the water that the Quest 70 is now sucking up had to be going somewhere.

I do notice that my central a/c is coming on a bit less to cool the house off. It's definitely not working as hard as it was after the Quest 70 was installed and I hardly hear the a/c drainage pump going off now. It used to go off 3 times an hour and now I hear it maybe 1 time every 2 hours. So there are some good upsides to this unit and not many cons as I can see so far after 1 month of use.

He's had that unit about 48 hours. His opinion is worthless to me, and I found his attitude overly combative. I hope he doesn't make any further comments.

Would it not be possible to seal the room and use co2 and an ac sized to take care of lighting heat and the heat of the dehumidifier? Then you’re only having to remove the water the plants transpire and it doesn’t matter what the rh is outside.

I’ve never had to use ac and never ran a sealed room so I could be way off plz don’t hate me haha

For me, no. I would need another a/c for the flower room and it can't be done.

Here in Thailand the humidity is endless, and I just lost 1/2 a decent plant to bud rot outside. I am accelerating my plans to build a flowering room; I can Veg outside and Flower inside. Problem is, even with an 18,000 BTU Split A/C running 24/7 I can't drive the humidity below 69%. I have a dozen plants, so they are drinking and transpiring a fair bit.

So... I am looking at industrial dehumidifiers. These are not grow-room specific.

My room is maybe 250 sq ft.
Of course, there is a range available going up to much larger spaces (3,000 sq ft).

My Question; should I be over-speccing? Do I run the risk of driving the humidity too low if I over-spec too far? Or is that not a concern during flowering? Can I drive humidity down really low without concerns?

If you can veg outside then why can't you flower outside? Get some Thai genetics and grow outdoors. They've been doing it for hundreds of years.

Too many "why this" and "why that" in this thread. I'm getting angry now!!

Soon we will have to write a book of explanations to make sure every RIU member is satisfied with our answers

Is it ok with you that after 20 years of smoking Thai weed because it was the only weed available, that I want to smoke something else?

Do I have your permission to grow what I want to grow ohh great lord of ROI?

You're talking out your ass (but then this is not your first shit comment in one of my threads!! Are you chronically unhappy sir?) I have good Thai genetics growing and suffered from bud rot, even after keeping them out of the rain with a transparent roof....

GFY

Piss off.

I like how you children claim ownership of a thread. It's not your damn thread. It's the property of rollitup. I'll post what I want on any thread you create. I don't care if you throw a fit.

 

[LoveBudz420]

Piss off.

Yes that's what I expected from an angry asshole like you.

Eat a bag of dicks mate.

And the child roars. What's with your obsession for male anatomy? Your kind always give yourself away with comments like that.

I just spoke to a Thai grower, she said they buy Cali genetics and grow for dispensaries there in Thailand. They're not bred for high humidity in Cali so rot could be common.

Heck if I could, I would trade you my entire collection of seeds and my current grow for some killer outdoor Thai bud.

It's really what made bud great, all these crosses today are meh and they are that way because all the good original cultivars are diluted.

Anyway...I have a room your size and putting a dehuey in the room adds A LOT of heat. As my electrician says...you either use ac or a dehuey...using both is a recipe for a lot of electricity and heat and waste.

#1 you have a plant limit because of the room. You may want say 8 big plants but the room may only support 4. If you overgrow your room you will be unable to control it, period. I learned this the hard way. Consider this carefully.

That said it's a small room. A minisplit + CO2 would be golden...high humidity, high temps and less need to vent if at all.

You didnt explain how and where the minisplit is venting the home...or the room? Clarity would be a big help giving advice.

Can you direct more of the ac from the mini to the flower room? That is the key to having more plants...otherwise you will need to limit plants and or volume of plants (size determines how many). I think in this size room, about 50 to 70gal of soil is the most I can run at a time. I'm not sure how that translates to hydro but in soil I would limit to 6 large plants. Preferably 4 if you have humidity issues.

There is always a solution but you have to compromise.

This is from the manufacturer

"We don’t recommend ducting the air out of the space, the exhaust is warm and very dry air that we need in the space to dehumidify the area."

I guess if it works for you, then it works for you. I'll probably not exhaust and just deal with the heat... I see a CO2 machine in my future also.

How are you dealing with high temps? Why not close the room put in an a/c and a 100 ppd dehuey?
What is your lighting?
What is is your plant count and how many gallon pots?
You have to calculate rate of transpiration with your maximum number of plants in the the largest pot, then work backwards.
Not to mention the amount of water each plant will get daily( or whatever your watering schedule is).
If you have any ambition of growing indica dominant you best watch the humidity above 50%.
