Definitely get the humidity down, make sure your probe isn't laying up against something or on the floor. It must be suspended or it's going to take the readings of whatever it's touching.Shit! Now I am in the danger zone for too wet! 78.8 degrees F and 89.5% humidity. This is tricky.
Current readings:
Wind Speed: 1600 RPM
Temp 78.3 Degrees F
Humidity: 76%
Air Volume 76.5 CFM
Wind Pressure 99 PA
No clue to what any of that means... but it looks like VPD is in range. Not if I Can hold these settings
I have Sun, Mon and Tue off.... I will be making adjustments.It's going to take some adjusting to find the right spot in your tent. I like to setup equipment when I can be home all day so I can closely monitor and adjust if needed.
Trust me, I know how frustrating it can be sometimes. I can't tell you how many different configurations I've ran until I found the right one. Endless hours looking at the Controller app on my phone and rushing back upstairs to adjust things lolI have Sun, Mon and Tue off.... I will be making adjustments.
Yes, sensor is on the floor. I will move that now!
Yep, very frustrating LOL. I moved both sensors above the plants. About 6 inches or so. Where I cannot read the humidifier, I do have the Mars-Hydro app for the fan and lights. I am monitoring that sensor for the temp and humidity. Adjusting the fan speed to try to keep it stable. Readings are different in the new location so I will be making some fine adjustments before work and hope I can hold it.Trust me, I know how frustrating it can be sometimes.
Do you have other thermometers and hygrometers?Yep, very frustrating LOL. I moved both sensors above the plants. About 6 inches or so.

If nothing else.... This will give me something to do at work LMAO.
I have the one from the humidifier and one from the fan. Both are above the plants as they are only 7/8 days old. Figure best where they are. I think I can get an app for the humidifier, not sure if I need the control unit from AC Infinity or not.... I have this running solo as I do not have their system.Do you have other thermometers and hygrometers?
Right On Mega! many years of growing before many of Us even heard the acronym VPD, Seedlings even young Veggers are less affected by Vapor Pressure / Stomatal Response as they are "not yet exchanging gasses (or transpiring)" like Plants in Late Veg, early Bloom or full Flower, good Vapor Pressures do aid the Plants ability to Transpire (gas exchange), but should only be used as a guideline... Born and Raised in Florida, Living in Minnesota 16 years, I went from High RH indoor Grows in Florida to Very Low RH Indoor Grows in Minnesota, Humidifiers can help in MN, but Ive had grows in the winter months with 10% RH and my Plants do just fine, they will adapt to an Arid Climate as it is built into their DNA. In these low RH conditions, you will keep them watered and Back off on Lighting/Temperatures, also run fans on low. Cannabis knows what to do!As long as it's not too hot I don't worry about vpd during the seedling stage.
Yes you need the Controller 69 to use the app with the humidifier. If you ever get the Controller 69, make sure to get the Pro WiFi Version, that way you can adjust and monitor away from home. The Bluetooth only version doesn't allow viewing and adjusting outside of Bluetooth range.I have the one from the humidifier and one from the fan.

Don't worry about VPD it will fuck you up as a new grower. Extremely foolish to go down that route IMO. Learn good temp and humidity ranges for each stage and follow that. Don't Over complicate shit or you'll kill your plantsWhat is vpd?
Also... Start veg? Isn't it started? 1st 4 weeks is the veg stage according to the nutrient grow chart. 5th week is flowering. I can adjust when veg starts?
Easy to take advice, hard to know which advice to take. I hope I am making the right choices.I'm very impressed, you dove into this with the attitude that you're going to be successful!
From the chart above, Temp and humidity is what I thought VPD was LOL. I am trying to keep in the range for temp and humidity in the tent according to that chart. I am not afraid of difficult things.... if this will be needed down the road, why wait. I expect this first harvest to be under par... hoping for the best through and trying to stay within the advice being given the best I can.Don't worry about VPD it will fuck you up as a new grower.

Seedling which is until the first 5 finger leaves appear is 60 to 80% , veg is is in the 60s, flower you want to slowly lower humidity over time to as low as you can but never go over 60% in flower. Temp wise 60 to 80 F lower in flower higher in veg. These ate just guidelines and the only definite one is humidity lower in flower, outside of that the plant will grow.Easy to take advice, hard to know which advice to take. I hope I am making the right choices.

One nice thing... since I added the humidifier my app alerts have stopped. I must be in a good range for their seedling setting.
When do I go veg?
So is that when I transplant into a larger pot? I do not want to go from seed pot to 5 gal bags. I know others have done that, and maybe I do not need a mid pot.... IDK for sure.Seedling which is until the first 5 finger leaves appear
Your seedlings don't look to tall at all, when you transplant you can bury the stem pretty much up to the cotyledons if needed.So is that when I transplant into a larger pot?

That being said... Can you please look here: https://www.thcfarmer.com/threads/are-these-too-tall-skinny.160366/?post=3124656#post-3124656
Worried they are too tall.
Dimmer is at 25% as recommended by the chart. I had the lights way too high. The chart suggested 12 to 24 inches above the plants. I was within that I believe, more toward 24"... just raised the plants and lowered the lights. I am around 11 inches above the leaves. Someone suggested to go to around 3" until the leaves spread out a bit. Not sure I can get them that low as I have a Deep red that I use that is on the edge of the main light. Trying to keep them under both. (or both lights on the plant)What do you have the dimmer set to on your light and how many inches above the top of your seedlings?
VPD or Vapor Pressure Deficit. It’s essentially a measure of (canopy/leaf) temperature combined with RH levels. There’s a sweet spot for all growth stages and seedlings usually like a higher humidity like clones, minimum of 60% but no more than about 85%.Hi all.... Silly question.
I have plants in early stages. 6 days old to be precise. My tent app is calling for heavy humidity during the "seeding" phase. However the stats on my seeds say these plants like a warm dry climate. So... humidity is running in the mid 40's to the mid 50's. I have been putting a large pan of hot water in the tent to build up humidity. But should I do that if the seeds do not call for a humid environment?
Thanks in advance.
On the plus side... I have an app on my phone to watch while I'm away....It’s a general rule to have your humidity 20 points below your temp so if it’s 80F inside the tent aim for 60% RH in veg.
Thought about a humidifier or maybe using a larger space?On the plus side... I have an app on my phone to watch while I'm away....
On the negative... I am checking my phone like a 13 year old girl.
temp 75.6
Humidity 84.4
If I raise the RPM of the fan, I suck out humidity as well as heat. Trying to walk that line.
