Haven't used it yet, but picked up a bottle of zerotol, supposed to be good for pm. I'm also looking into a company called prokure for these little packs that are supposed to help make a gas that will clean your room, pretty sure it's only for between runs but still trying to figure it out and find some locally.

Depends where in the grow , Sulphur is my go to. If its not from my clone supplier then I don't see it. I try to main tain a sealed environment but with cold air outside and expensive ac s on the inside then its a no brainer to expose the elements, I run into a minor filtration room first.
I run 3 rooms with 8 gavitas in each, swap 2 with 2 630de cmh im week 4 and the uv of those keeps things clean.
Whats ur humidity at?

Do you not see all those fans? How much air movement do you want?

Why do you swap for ceramic metal halides?

Nice setup man. Im crossing my fingers you don't run into pm issues. Have you used sulpher burners before? Those humidity numbers youv'e listed are going to be tough to keep it at bay. Those spikes even when only for short periods can be all thats needed for spore growth. Remember too that the lower the temps the tougher it is to keep humidity lower and your dehu is less effective. I was having trouble keeping my lights off humidity spikes below 60-65 with my dehu's, so i tried running the vents instead but they dropped the temps so fast the humidity still spiked. I was chasing my tail till i finally ponied up for a commercial dehu. Also as someone who tried to do a semi sealed room with in and out vents, ac and co2, don't bother with co2 unless your fully sealed lol. Even in a smaller room you'll just be blowing through the co2 like crazy.

I thought that the colder the air is the less moisture is could hold? The hotter the air the more moisture it can hold hence why its always way drier during the winter. My humidity with a second dehum is around 60 during lights on and at night my intake turns off so my humidity drops to around 50ish during lights off

What is the proper temps and humidity thst I should keep so pm isn't as much as an issue. I have products that will keep it at bay I really think it happened because I didn't prune at all untill 3 weeks in and plants were super humid and bushy

Ya doing full leaf strips at 2-3 times during flower will help with airflow throughout the canopy. Are you running vents when your lights are on or ac and dehuies? If you could get your lights on temps up you could probably drop your humidity. If ive had any pm on plants in a room i would do everything possible to keep the rh to 50 or below at all times. Pm fucking sux!! And ya for sure your right about temps affecting humidity, hence why its relative to temp. Your lights off numbers look ok, although 68 is getting a bit cold.

Word i can get my night temps.up no prob just checked the room I turned dehum up and room was at 46RH right before lights off now lights are off and mini split turned to heat mode. Turned it up to 70F so night temps will be 69-70ish with 40% RH and lights on 75F with around 48-50 max

Maybe I'll do a sulphur burner or do you spray sulphur im nervous about spraying sulphur in flower. But I guess the same effect im 30 days on a 12 weeker so maybe sulphur will be okay if I do it tomorrow would everyone suggest sulphur burner? Any tips or tricks to it? Im still gonna spray next week or so while buds are small

Nice, if you can keep that rh in that range it will deff help with slowing any pm growth. On a long flowering strain youd be fine to burn or spray up till about week 5-6. Ideally you dont really want to use sulpher once you have buds but your still in the bud site stage so should be good for a week or 2. Upside to using a burner is it gets everywhere in the room, so it can kill spores that are on the floor, on fans, etc. Whereas spraying your just hitting the leaf surface. If you havent used a burner before do a bit of research so you know what your doing. Make sure All fans and ac, dehums are off, dark cycle obv. I usually wait an hour or 2 after lights off to make sure stomatas are closed. PLug the burner into a timer and set for how long you want on. Usually start with a shorter 2 hour burn, just to make sure the plants dont react weird or get burned pistols, then ventilate with exhaust fan. Want to eventually get to 4-6+ hour burns. I use 2 burners in my room thats 23x24x10 to make sure i get a serious fog in there lol.

Good advice you da man, pots are light so im gonna spray tonight with nuke em which is a contact killer for pm and see how plants react. I have had success controlling pm in light dep with green cleaner and nuke em then followed up with armory and biological products to out compete mildew its definitely still growing even tho airflow has increased and RH and temps in good range seems once germinated It stays growing even if conditions switch. Pm is easy to deal with compared to botrytus m, russet mites, and root aphids. Its super visible. Once I do a few round of contact killers I'll spray armory and met-52. If all else fails then result to sulpher burning. My hypothesis is that if I can out compete the mold then I should be in good shape. Thanks for the advice I know I got this. This is why I'm in my room constantly. To stay vigilant and catch things early

Day 32 GMO Cookie
Not so bad if I do say so myself. Its funny the square footage of my first indoor is the same square footage almost of the size greenhouses I was pulling a zip per square foot with during mid summer dep. My room is 13x29 and each three greenhouses used to be all 12x24s with beds and a teo foot center walk way. Indoor Almost identical cept a foot wider in center isle and 5 feet longer of a canopy.....

This up coming Saturday is 5 weeks. All I can say wow this strain is the most stretchy strain I have ever seen in my career. What I have done is I decided to add the c02 generator and put exhuast on thermostatic controller to just exhuast at night to get temps higher and humidity lower and to get within that VPD range. Room is @ 77-80 canopy 62-65% RH level 1500 ppms c02, feed strength @ 480 ppms last feed. Using a combination of organic imputs with salts aswell. Tomorrow I'm going to be spraying another round of nuke em. The room is really humming now, the goal is to keep my nitrogen levels up so plants dont fade early. This strain can be feed N for a long time as it stretches so much. Buds are steadily growing. Been taking off fan leaves periodically. Im hoping that the reward will be worth the weight if this was a 8 weeker id be concerned but it takes a long time to finish she still early on. Another 45 days to go!!!
