Concrete slabs and humidity

Someones triggered. Your method of stressing the plants at the end is retarded. Much better ways. All you're doing is prematurly drying your buds before cut. Losing terpenes. No point even explaining anything to you because you're so right and all. Getting mad over a couple posts shows how mature you really are. Lmao enjoy your day bud

Oh does concrete hold water? Well duhhh it does its made up of mostly water. Lets talk about science?
Can't fix stupid

Using the word retarded in a form of insult is real mature isn’t it. Losing terpenes dropping humidity? Sound like you need a lay off some of that organix stuff. No way he’s losing terps if he’s trying to get humidity at 40-45% when plants are still live and well.. so please tell us how to stress plants better? Concrete is made of water mostly? Try aggregate buddy... science

Op why not install an exhaust with a damper, works wonders in my seal rooms

Lol with water... it still has water in it same amount as concrete sure theres aggregate lolhes still right too. Ofcourse concrete will absorb and evaporate water thats his point.

I’m going to have to disagree with your theory that water is equal parts in concrete..
Organicbud did not make a point about op questions, he question op growing ops with an sarcastic insult without insight, I’m still waiting on what methods of stressing the plants organicbud uses that is much better than op..

Also hes trying to drop humidity lower than 40 like 35 %. At that point its o ly

Cement and water form a paste that coats each particle of stone and sand—the aggregates. Through a chemical reaction called hydration, the cement paste hardens and gains strength. ... Typically, a mix is about 10 to 15 percent cement, 60 to 75 percent aggregate and 15 to 20 percent water. So technically theres more water than actual cement but more aggregate than anything. Not that it really matters and is still a dumb question

Thanks for proving my point.. not equal parts... clearly stating not “mostly”. Geeeezzz

So what o ly means? Still not proven dropping humidity late in flowers hurts terpenes unless you thinking bro sciences.. if it works for him then it works but yet you 2 still haven’t provided facts that it hurts...

Theres tons of articles about it. Simply dropping night temps is a much better alternative. Are you a butthurt one now too? Looooooool so many snowflakes ... oh dear. Must love shitty weed and crying. But thats riu in a nutshell

I love the assumptions without the facts...must not be reading what op says, clearly he says he drops temps along with humidity, but humidity is his issue..

@Therrion I don't think the concrete is your issue. Rainy weather should not affect your sealed room "in theory" but as Yogi Berra famously said, in practice things can be different.

Rather than hunt for holes in your sealed room, I think your RH issue is coming from having a bumper crop with lots of transpiration. Compounding the problem is your desire to lower temps AND reduce RH at the same time; these are conflicting goals, since RH falls as temperature rises.

What I think you need to do is add heat in your room, as in some kind of heat source. The issue might not be wet concrete so much as cool temperatures sucking extra heat out of the room, which would interfere with the operation of your dehueys.

These are just educated guesses based on what I saw of your grow in your other thread.

The more you can tell me, the more I might be able to help?

concrete is indeed porous, however a concrete slab sits atop of crushed stoned generally speaking moisture coming through the slab would be next to zero. if your generally concerned about this my suggestion would be to apply a two part epoxy to seal the slab dont be a cheapo and get the one part those are junk. hope this helps answer your question.
one problem to apply epoxy the plants would all have to be removed and the fumes that would come off it would be detrimental maybe on the next run unless you can move them and the lights for at least 3 days
 
As the title says, I have a sealed grow room on a concrete slab. I use a quest 105 commercial dehumidifier and recently introduced 50 pint/day floor unit as well. I can't get my humidity below 45% no matter what I do . I have a combined 20' x 12' split between a flower and veg room that swaps air. My actual grow space 2 x (4' x 8') flow tables. I live in an area that gets plenty of rain, My question is, How permeable is concrete to moisture as far as it seeping through and keeping my humidity high? They are painted with a shitty white gloss that are already flaking. Would a concrete sealer fix this issue? My combined plants consume about 22 gallons of water a day. Maybe I just need a way bigger dehumidifier due to all that transpiration?
I got a bit down this thread before it turned into madness so not sure if your question was answered but an epoxy seal will work fine. I personally had a bunch of free pond liner and used that works just as good a little harder to clean but probably just to the eye not in actuality. Any kind of paint will chip away quickly you need that roll on epoxy and put it on thick if your slab is porous. I grow in PNW coastal weather can attest to this question. I did pond liner two friends did epoxy both work great. From the sound of what I've been told the epoxy is easier. Go with price in your area or ease of install. Whatever works best for you.

Edit: Just realized you are swapping air between your flower and veg. If the humidity is high enough in my veg to be condensing and dropping in places I'm happy. I would never introduce that air to my flower room. There's no way you are going to get the humidity in your flower you want if you're sharing it with your veg. They should be completely different and independent spaces.

easy fix seal/paint the floor is a must , had the same issue, need to watch garage floors as concrete(if not sealed) will soak up anything and when it gets warm/hot it leeches and smells- believe me nothing worse then the smell of fuel/oil in your grow rooms- big job having to start again -do it right first time :wall: :eyesmoke:
