Looking for opinions on my three autoflowers

[Tom Bombadil]

You got bad advice from someone in this thread. Running plants at 30% RH is not good at all.

i assume youre referring to me lmao..I didnt tell anyone to run their rh in the 30s, I said i have done it with no negative effects, which is 100% true..Not everyone can control every aspect of their environment every grow...especially when just getting started, and im not going to tell someone that is new to growing that their grow will be shit because they arent running co2 or have perfect rh..These are rugged plants that can manage to adapt when needed..For instance the autoblues x sourbubbly plants below are 40 inches tall, left top bud is the size of an nfl football...rh in the 30s. Not ideal, but manageable. Following a vpd chart is optimal, not argung it isnt..just that its not terribly detrimental..
No hard feelings.
peace friend

Peace, Tom.

I just think its important to steer folks in the right direction. My dumb ass missed the part about the thread starter growing OUTSIDE in a tent, lol.

So what do you recommend for me? Temp/rH wise

You can google VPD charts, look at images and there will be charts for each period of growth. There are also lots of videos on youtube explaining it. I am not saying you can get it perfect but it can be used to guide you. Having an understanding of it also helps. It also depend where you hygrometer is placed. You will get a more accurate reading of what the plant is at if the meter is close to the plant vs on the wall of the tent. there can be quite a difference in humidity and temp.

yeah, my tent is indeed outside, but I’ve managed to take care of environment issues, if I need my humidity or temps to be higher or low, I’ve sorted that bit out, but it is still a bit challenging. - I do have an exhaust fan

I do wanna buy this one tho

Maybe your pressure inside the tent isn't negative, its great if it is. Exhaust CFM should be double that of intake CFM. Here's a decent exhaust system:

After this thread I'm done giving out advice. Research deeply and you won't be posting questions to anonymous people.

Right idea wrong parameters - Sooner or later we will all get sucked into that tentA little negative pressure is good but the volume of air in must equal the volume expelled or that sucking sound is us being pulled in. -- Well it could happen .

I live in the desert and it is not possible for me to keep my space in VPD parameters. The outdoor RH reaches zero! So even with a swamp cooler the best I can do is 50% RH If the plants are big enough I can get it up in the space a bit more but no where near the VPD best zone. I tend to grow Photoperiod plants in the summer as the seem to handle the high heat better. I think I may grow autos this summer? I try to keep the grow space >40%<60% RH

@kushitslit Lots of us here are happy to answer questions it is the AFN Vibe It is up to you to choose which Bro-Science to follow or none of it and blaze your own trial.

I use as cheapo inkbird temp/humidistat connected to my exhaust fan and as long as temps allow, I will only exhaust the air when it gets overly humid. I thought this could cause concern with not having enough ambient co2 in the room between vents... but ive seen no negative impact in that regard either.

Simple rule here is that relative humidity is inversely proportional to temperature . Getting and keeping those heat/rh parameters to stay kinda close to the sweet spot without alot of expensive equipment takes a bit of time and effort, but its doable.

Nice exhaust system, Kush. I also run the AC Infinity Cloudline T6:



I also fight an environment that is super low RH but I defeat it. My basement has 20-24% RH. I will put one, two or 3 humidifiers in my tent. Whatever it takes to hit the RH I want. I'm less then 200 miles south of Canada, and its wicked cold in winter. I gotta run a ceramic 400 watt heater 24/7 in Jan-Feb if I have a run during those 2 months of the year. Its outside the tent, pointed at a low port/vent hole 4".

Hahaha, exactly man, trial and error and we just gotta see what works for us best. I’m definitely experimenting this grow and it’s my first autoflower grow ever, I topped two of the three plants and now looking back it I regret not topping the third one lmao, but yeah I’m looking into VPD as well, but I got a PTSD from my last photo grow that had mildew cause of high humidity issues. So far, this grow has been less of a Headache and way more simple than a photo in my opinion. Anyways thank you I do like the community here, and I appreciate everyone’s advice, truly.

Exactly, I need a temp/humidifier sensor to connect along with my dehumidifier and humidifier and my exhaust fan. I’m looking into it still. Everything in my grow in automated all from a touch from my phone or Alexa, the only thing that isn’t smart in my tent is the watering system which I plan to get a smart auto water’

Thank you bro, and yeah I have a heater currently and it does an amazing job, it’s a super small one but hellaaa heats up my tent, plus I can control it from my phone, I absolutely love having a smart grow setup. I highly recommend it to everyone, I got 3 cameras in tent too
I do appreciate everyone’s advice here.


— Also,
Regarding the photos of my plants, everyone thing they look okay and are budding fine?

Im with you. I cant control the H where I grow. In the winter its super low. I don't grow in a tent, I'm in the corner of one of the rooms in my basement 20x30. I have 5' reflective partitions walling it off. So I don't worry about the RH, just grow.
