Indoor Mephisto, HBSS - Two Tents Two different pot sizes

[peargrow]

So i been searching the blessed and hallowed web for info regarding RH% ( education education education prime minister ! ) and I stumbled upon this on another forum and pipped my interest has anyone ever heard of this little remedy of oils to prevent mold ? anyone used this and had sucess i love to hear more about this.

"70% @ 70° F for the win. I diffuse a blend of rosemary, lemon, eucalyptus, clove, and cinnamon oils to kill all airborne pathogens. Never seen botryitis or any other mold since I've used the essential oils. PM does not depend on humidity to manifest, it prefers big temperature fluctuations.
Google "VPD" for some fun reading, or find the thread her on the farm.
I've had excellent consistent results since I became aware of vapor pressure deficit in my grows.

So so so How much is there to learn ! Its a never ending learning curve !!! After @Waira suggested increasing the Humidity I started looking into Humidity and who knew how important it was ! boy am I pleased I started this diary growing Autos really gets you to know your ladies and hopefully improve your grows big time.

I read the shit out of this post excellent read and i recommend you fellas take a look https://www.thcfarmer.com/community/threads/lies-our-fathers-told-us-humidity.55435/, this guy ttystikk this guy really seem's to know his shit and I had @pop22 point me in his direction once before so his info should be carefully taken into account.

So that little read lead me into the world of VDP (pffftttt its never ending) but I cant get enough of this stuff and led me to this read https://www.thcfarmer.com/community...ty-some-valuable-information-must-read.32374/ Again take a read fellas well worth it.

It's left me with a Q though both post clearly indicate that high RH% is NOT the cause of PM but bud rot is not so much discussed if I have my room running at 60-70% RH what can I do to prevent bud rot because I had this issue in my grow before with some of my big buds.

P.S - Any advice how to raise my RH% (With out buying a humidifier) I'm struggling I tried putting a pots of water sat on a stool , 2 big towels soaked and hanging from the bars of the ceiling of the tent and i can't get it to budge beyond 40-44% My tent has lots of little vent i can open and shut I had opened these the last few days to help keep the temp down but will that prevent the RH% increasing as the air is escaping and not building ?

I've had enough struggles with low humidity bro, look up orchid humidity trays.

I used the same concept as people who grow orchids indoors, only on a lager scale, filled a large plastic tray with stones, and then filled it with water.

I'm not sure you need to be that higher humidity, I think you'll be perfect at 40%

I found low humidity caused my plants to stunt especially vertically and fan leaf width, due to low aspiration, but that was really low, like 15-22%


Low humidity in flower isn't a bad thing, as it is supposed to increase resin production, I'm at 30-35% in flower.

Good airflow over the leaves is also important for aspiration.

Thanks for the tip on the orchid humidity trays i'll take a look at them i just found an Phillips Avent baby steriliser for bottles lying around in the cupboard must been left by a previous owner totally unused ( stroke of luck maybe's ) but it looks like it's only supposed to hold a 100ml or water might do the trick I don't know going to give a go now . On higher HR% and VDP i suggest reading the links Dark my friend its an education and how it may benefit your grows in the future.

Note that the guys running high RH are also usually running in a sealed environment and using CO2 and high temperatures also. Its the combination that's effective, not the single factor of the RH.

and the same parameters apply to disease control. For infections to occur, there needs to be three factors for them to take hold: Temperature, RH, and a source of infection. PM, bud rot, and other molds require high RH, but low temps to take hold. You see PM outdoors on squash, etc late in summer when RH goes up, but night time temperatures drop. Boom! next morning PM! Same with your indoor garden. Thick buds hold a lot of moister. When RH is high and temps drop at lights out, that's the door being open for disease.
I don't know if RH has had any bearing on my harvests indoors, but I've never had a PM or bud rot as my RH tends to be low. In summer with the airconditioner running, my growroom stays in the 40-50% RH all summer and I don't do anything to change it. IMO, unless its very low ( below 30% ) or very high ( above 55% ) its a waste of time trying to change it. Running very high RH is only effective when combined with a sealed room, added CO2, and temps in the 90-95F range .

Afternoon Pop's I have taken into consideration that it was a combined effect that would make the RH% a more relevant factor, I think my garden hits enough factors - current low RH% 35-42 leaning more towards the lower end on average of them figures, and the low rh% is causing my ladies problems as Waira had pointed out. My temps are at the high end between 27-29c / 80/84d and Ttystikk suggest that is the right temp to be looking for rh% of 70%+ and goes as far to suggest if your at 80+ and not at 70% you're going to have some issues that certainly the case with a couple of my ladies

As far as sealed room goes. I like a second opinion on this could i class my garden as sealed room ? Grow Qube with a number of closeable vents which are now closed again 8 inch mix fan and filter I do have a passive intake and outtake outlet (I can do away with this and close the seals and get rid of the outlets not until i solve the temp issue - probably with my new led lights in my next grow - does that intake/outtake outlet kill the notion? could class my Qube as sealed ?

CO2 - None of this but i could begin adding it if i can get the temp correct and the rh% right

Either way I feel like it's important I get my RH% to around 50% to try and prevent any more damage to my ladies and help them cope with my higher temps at the very least - Any suggestions here with out buy a humidifier ? If a Humidifier is the only reasonable solution any recommendations on a good one ?

Closing the seals works ok. Many people use an anti-backdraft valve in their fan duct and outfit their fans with a thermostatic control when they need to shed heat.

Humidifiers tend to suffer due to the fact your extraction fan will be sucking it straight out, you might gain 5% or a bit more gain, but I think a slow wick option like water trays and wet towels which evaporate slowly are the way forward.

Worked for me anyway

There all in there tonight mate wet towel bowls on the floor big blocks of fucking ice and we are still struggling

I know, I'm running around with trays of water like a dickhead when I've got girls vegging.

Stick at it bro, just keep it moist and watch for fire hazards and it's all good.
