Best way to setup room with plaster walls?

[diggs99]

Enough RH% to cause condensation on the surfaces... Many factors but insulation, wall temps are big. It happens most around windows where cold causes lots of condensation in the winter.

Yep, this can def be an issue. i remember back when you talked me into drywall and plaster, best thing advice ever. Easy to clean, fresh coat of paint and its like new again lol..

I run my room on the high side for RH....70% + ....i combat other issues from arising by having hurricane force winds in the room at all times.

No issues with condensation or pm or mould on any walls yet. Only the fkn intake fan, thats always dripping. Still havent found a remedy for that yet.

I never did either short of encapsualting the fan in spray foam lol. Thats why, when you were planning your build, I told you to make sure the intake location wasn't above anything like a light.

Lol spray foam entire fan, might be the only way haha

I've been reading here and there that high winds are a major trick to preventing problems, any recommendations on fans for the room that I should look at? I did a search here but came back with mostly smallish oscillating walmart and amazon stuff that looked meh.

I still will panda film my most thermal shock prone areas as well I'm thinking, and will need to secure the film against the additional winds. Film is on the way but the cold season may end before it gets here...

Quote from DJM @ IC:
"Mold is a product of not enough "wind" in the room, not a product of high rh. I challenge anyone to prove me otherwise . As I've literally never had budrot or mold indoors in over 10 years. My room feels like a tropical storm though. Every single branch dances In the breeze. If they didn't, they would rot, but that would be because of stagnant air , not high rh. A lot of miss information about high rh and temps going around from people without first hand info or badly designed rooms with bad experiences. Who think 75f and 50% is ideal, which its far from unless the lights are out and even then it's still too dry. And if you run co2 at those temps you might as well burn you're money, as it will make no difference. Like I said I'm not going to convince any one . They can stick to what everyone thinks is ideal. But I trust my plants and eyes, not hearsay from growers who never step outside of the box of what others do and experiment
And another reason people are scared of high rh is pm. But pm is systematic and lives in the plant , so if you have pm living in the plant and it pops up, the issue is not rh but you having to rid your plants of pm altogether"

[A Prior DJM quote for context:] 84f and 75% rh through the whole grow, 70f- 74f and 65-70% at night...its hot and wet..glasses fog up when you enter...only the last week of flush will I drop it to 75f and 65rh ...during veg I run it even higher around 86-88 and 80%rh ]

Is Powdery Mildew Systemic?

Cannabis growers are divided when it comes to whether powdery mildew is systemic, but what does the science say?

www.medicinalgenomics.com

thats an interesting read.

That it is. Reading it leads me to the question of: What are some interesting PM resistant strains?

Though hopefully with the hurricane going on in there I wont ever see PM

plaster ? never tried it ...me I would go buy some osb sheets from loews /home depot same stuff they sheet roofs with frame out my walls with 2x3s or 2x4s and wrap the inside with white plastic and call it a day

That's counter productive. Covering quality plaster work with osb or drywall is a material downgrade and would require much more work and materials in the end.

@fragileassassin im not sure if you misinterpreted this as @bulla suggesting the OP replacing the plaster and put up drywall.. but i believe he was suggesting build a quicky frame and plywood it so that OP actually has walls that he can screw/nail/staple/tape to without the hassle of damaging the existing plaster. As someone who has restored 100+ year old homes- where wood lath and plaster is the norm- i can promise you that the small expense of lumber/materials involved in this will pay for itself 1000x over vs damaging and repairing the existing plaster.

edit: as you already suggested @fragileassassin a tent would also be an acceptable solution, i love my tents!

I didn't think he even had a room I thought he had to build a room in basement I didn't know he already had was I thought he wanted to build plaster walls and I was

Well Durban Poison is supposed to havr resistance. Honestly PM is like the borg once you get it, resistance is futile. So the key is to prevent conditions that cause it to pop up the first time. Once you get it, even low humidity and good air circulation can actually help it spread. And as that article states, systemic or not it has a way of hanging out...

quick question for the OP- Do you have a basement? i only ask because the majority of homes that were built during the time that plaster was the norm do have them, and if so i highly encourage you to set up down there! basements are the beeeskneees for growing as long as you have a way to exhaust outside. I was sooooooo close to buying a farm house built in 1873 just for the basement.. the 65 acres of land it was on wouldve been a killer bonus also but the basement was a growers dream- except the snakes lmao! sadly my 375k offer wasnt enough for the owners to budge xD
