VPD Made Easy | Dial In Your VPD With AC Infinity Controller 69 Pro

[@HappyHydro]

How do you guys manage your VPD?

[@timm_3r]

Very carefully. 🤣

[@123fatbuds]

I run my 6 inch exhaust in vpd mode to kick on below 1.2 and humidifier to kick on above 1.4 runs great . I'm in flower 👍

[@nikolasmaes99]

The chart from Pulse will be a great help, thanks. I live in an old apartment block, it's always quite humid in here around 65% RH. Lowering the RH with dehumidifier doesn't seem to do all that much so I'm considering increasing the temperature in the tent with heater. You reckon that's a good idea?

[@Catch_u_reloadn]

I'm not to versed in VPD. But I usually keep it like a 73 degree summer day and 50 plus rh in veg and in flower like 69 to 71 degrees and 40 rh or lower.

[@HappyHydro]

[@rayjay8322]

In the past year, I have become an AC Infinity nut!🤣 I have three tents in my grow room, 4x4, 3x3, and a 2X4. All three tents have smart exhaust fans with the 69 controller. I don't use the VPD section of the controller. I have a window unit AC for the cooling, a dehumidifier And a brand new AC infinity humidifier, that big 15 liter one....... That thing is a beast! The window unit and humidifier controls the lung room environment And I use the fan speed setting to control the temperature in the tent. I ALWAYS have some air flow in my tent, so I have a minimum setting on my fan and then I have a trigger temperature set for the fan to go at a higher rate to bring the temperature back down. Each tent has different lights and different thermal loads, but all three tents have the same style of air flow. The 4x4 and 3x3 are both Gorilla tents and the 2X4 tent is a Mars hydro. On the Gorilla tents, I use the front lower cinched inlets with 6 inch exhaust hose with a screen covering to bring the air into the tent. Just enough of the hose sticks out for it to lay flat and long enough to prevent light intrusion. I used the exhaust hose from the AC infinity 6 inch exhaust fan in the 4x4 tent. It is reflectively lined on the inside, so I fogged the hose outside the tent with flat black paint to knock down the light intrusion even more. The 2X4 Mars tent only has cinched openings at the top, So I use a very long 4 inch Exhaust hose to bring in the fresh air. Comes all the way back down to the bottom of the tent and to the bottom of the floor outside the tent. This way all tents take cool air from the bottom of the lung room and all tents have air flow from bottom front to top rear and it exhausts out the very top. The ceiling fan is always going to keep the lung room air mixed well. This maintains the long room parameters very closely. The tents parameters are just as stable. The CLOUDFORGE T7 Is an absolute beast and is highly accurate! It handles my lung room quite easily at setting 2. The absolute only downside so far is not being able to control it with the phone app when used totally on its own. You can use it with the 69 pro controller, but that is really only for one tent, because it uses the sensor from the 69 controller that is in your tent. With my Grow room set up in this fashion with AC Infinity, my environment has been rock steady! It's been one less thing to worry about and having to constantly check and tweak. Today I will be finishing the installation of my AC Infinity controlled CO2 augmentation! I'll run the hose to one central location in the grow room and then equal length identical hoses with a manifold at the end to distribute the CO2 to each tent, I'll zip tie each manifold to the top bar at the front of each tent. With CO2 being heavier it will fall down to the bottom and being stirred up by the circulation fans, which are AC Infinity also! Each tent will get a supply of CO2 through the manifolds and through recirculation, I think it will be a glorious run! I really love everything that I've gotten so far through AC Infinity! And this smart controller can make your life so much easier!

[@HappyHydro]

Wow! That's awesome to hear!

[@rayjay8322]

@@HappyHydro Well I thought maybe your listeners could gain a little bit with the detail that I went into. It just really simplifies the grow and the only time you need to make any changes is when you up the light or you're at the life stage where your VPD needs to be changed. My temperature and humidity in the tents are rock solid and only vary by a few degrees.

So it is sort of safe to just ignore the leaf temp? The temp in my tents goes up and down every day, especially in the summer. Accounting for the difference between the leaf temp and the tent temp seems like it could be a part-time job.

[@esgehtvorwarts8929]

So i do live in south west germany in summer it is very hot, environment temp in my room where the tent is is about 26-28Celsius... what u recommend? Thx,

[@HappyHydro]

Hey there! 26 -28C is not a terrible range. If you can keep your tent temperature a steady consistent temperature by staying near or below 27C you should ok. If you notice your tent is getting too warm you may benefit from adding some air conditioning to your lung room so that the ambient air around your tent is cooler. if you have more questions feel free to shoot us an email to [e-mail]

I can’t keep my vpd in a proper area…my temps fluctuate during the day between 85-82F and night 75-77F and humidity ranges between 60-70% both day and night…vpd stays around 1.1-1.5. I’m genuinely confused as to why I’m having trouble if the temps and humidity seem to be within proper range??

[@HappyHydro]

Honestly… don’t worry about it. Those temps during day and night are fine… and that humidity is fine (probably want it lower in Flower, especially towards the end). You’re good this is just a new metric that people didn’t follow at all 10 years ago.

I am new to the AC Infinity world and am a Plumeria grower. When you talk about the VPD regarding plant health, sweet spot of optimal amounts of moisture, vegetative and flower kpa's-is your info for just the marijuana plant or all plants? I'm assuming every thing you said is for all plants, flower or vegetable plants or just the marijuana plant? You showed the Pulse chart as well, same question, is it just for marijuana or all plants? Are different types of plants have different kpa levels for optimum quality and yield for flowering plants? Hoping your info is for all plants and not just for the pot plant. Loved your info!

[@HappyHydro]

Different plants will require different VPD levels at different stages of their life!

[@camarodude9615]

Great info👊. it's ok to run RO water in the humidifier,i just switched to a RO system the plants are loving it in auto pots an a RDWC system.But thanks for the info bro

[@HappyHydro]

Thanks for the info

[@amphetagrooves]

the only improvement is to please add an automation that can be set to change the VPD leaf offset for night (0) and then to day (-4)...otherwise the Auto VPD triggering is kind of not automatic, as you have to 're calibrate' every transition from night to day in order for the triggers to fire properly ... enhancement request - thanks - the rest of the system is super awesome

[@codyhartt7022]

@happyhydro it’s tough out here in Arizona … tents constantly going thru about a gallon per day to keep humidity level … we don’t use VPD triggers but are using humidity triggers with buffer and transitions using the AC Infinity 69 Pro. Exhaust triggers as well for too high temp and too high humidity it’s pretty stable but any ideas how to control the room better

[@sybermile]

I'm in AZ to humidity and AC 😢

[@HappyHydro]

It’s going to be tough in dry and hot climates. You’re fighting against an AC that pulls moisture out of the air and just dry conditions in general. Have you tried putting buckets of water around in the room to help keep humidity up and more stable?

[@cloudysky1974]

I dont run a dehumidifier, I increase airflow dramatically if its to humid. So far I have been lucky, its good enough. I do run the AC though when its needed.

My question is ... for us growers who have $$$ in other growing equipment. Can we connect to this ac infinity pro 69+

[@HappyHydro]

There are ways to get some of your other grow tech to connect to the controller. They have an adapter for lights which is cool and will allow them to communicate. Also they have a smart outlet, which will allow you to control whatever is plugged into the smart outlet through the controller. The only downfall is its limited capabilities as in it can only turn the device plugged into the outlet on and off.

[@UbiquitousRomp]

Good explanation of VPD, but you figures are a bit high compared to other scientific studies i've seen. You must live in a warm climate, so even when you are on lower power light in veg, you are still able to create high temps. In Europe and other cooler winter climates. it quite hard to get over mid 70's in early veg renning LED's, But a VPD of 75 -90KPa is just fine. Anything over 1.0KPa in early flower works well and 140 is the figure most give for mid to late flower.

[@anthonyromano8565]

I may have been over killing my ventilation and having steady high VPD. Now I have a VPD sensor on my new T-3 humidifier I now have my exhaust on low on off at 15 minutes intervals on a timer which saves power and keeps the humidity just about right so far based on leaf temp off set. Its all built into the humidifier. Had issues with leaf tip burn and stress. Going to keep it .9 as the lowest humidifier turns on and it goes down to .84 and shuts off until it gets to .9 and turns on. I need to change that I think. Although I have wide leaf strains that are supposed to like it dry. I will set trigger to 1.0 instead of .9 for late veg . Something I never tried. I always ran my dehumidifier when I probably should not have for the last 4 grows that did alright but could have done batter. I want to see the other extreme now. But now my living space humidity is a few points higher. I prefer it lower a few points.

[@UbiquitousRomp]

I dry using VPD and aim for between .77 - 85 KPa by dialing in the humidity level to the ambient temp to create the VPD desired. and get a 7 day dry in summer or winter.

[@HappyHydro]

Heck yea! Sounds dialed in

[@Ben84s]

7 days is way too fast to dry bro

[@UbiquitousRomp]

@@Ben84s Not according to the latest science. 7 - 10 days is optimum dry time now. the canatron dries it in 5 -6 days and even professor Bugby now says the old school 14 day dry is to long and the tricones break down as they decay. There was also a female scientist from the industry on Garden talk not to long ago who says the same thing. So I'll stick with what I'm doing as it works just fine and is now backed by science and not bro science..

Those award winning farmers in the Cali mountains dry at 70f and in containers of Barnes, with the humidity as high as 70% and a 7 day dry. they call it all the 7's and it works.

[@Ben84s]

I have just always preferred the results of the longer dry of 14-16 days myself using what’s available to me in my home controlled environment. I bet the Canatrol would be the best way to do it because it would be a much better at controlling the dry environment then I could ever do in my home using an ac, dehumidifier and humidifier setup. One day, If I could afford the 4k cost of one, I’d love to have one.

I have about 24 hours experience. I think the real goal is to save money on power from dehumidifiers is top priority. This makes it easier on the plant making it healthier with a better immune system which could fight off Powder mildew. On the other extreme you rum the dehumidifiers to much you waste power, the plant is stresses, that lowers its immune system to fight off powder mildew and you just kicked yourself in the nuts. I am currently saving 50 % power on exhaust fans by placing them on a timer.
