Yeh, I don't really disagree with that at all. Always be led by your plants. I'm just wanting to at least get them in to the right window for, in this case, flowering. I'm certainly not micro managing numbers related to a chart, my brain is full of enough shite as it is...lol! So I'm there or thereabouts already. Just need to sort that bloody humidity out tbh.

I've been using these below as a reference, will take a look at your Dimlux recommendation also, thanks:

VPD Charts in Fahrenheit and Celsius With Leaf Temperature

We made some easy-to-use VPD charts for both Celsius and Fahrenheit, for clone, veg, and flower stages. Hope you find them useful. For more information about VPD check out our VPD Guide. VPD Chart Maker and Calculator I WANT IT Table of Contents VPD Charts for Fahrenheit VPD Chart for Clones...

Pulse has good charts also and is one of the few that include leaf temp differentials.

That’s so cool. I see people using heaters on here which are a total fire hazard. I don’t need a heater where I live. Would love to see someone who does review it.

These things are garbage like everything ac infinity makes. The definitely will be running full blast and still not keep the temp you want.

Have a 69 pro, a cloud and thermo forge.
The thermoforge puts out more heat at setting 8 than 10.
It will lower your hourly temp trend to .1 up and down within reasonable limits.
If your basement is 55 it will not get you 80 in a 4x4 with duct setting 5 but ask it to do reasonable things it will.
The thermoforge is great. Only complaint is no level sensor for water on app display.
Also will need multiple cleanings during a run so plan on that.

And Vivosun has one about like it now.....

It is 65 in my lung room and it is piped in with one short pipe all the way scrunched in and it will not raise the temperature 10 degrees in a 3by 3. Every thing ac infinity makes is mad produced garbage.

My guess is that you prolly had zero core science, technology or math in your life and no one taught you the very long list of rules that the universe runs on.
The ACI thermoforge has a 530 watt total system operation load. A 3x3 tent that is 6 feet tall has 54 cubic feet of air. The requires for raising temps of 54 cubic feet of air one degree can be easily found online and can be converted into watts. It can raise the tent based on duct setting between 1 and 8 degrees.
Again use of the thermoforge is to stabilize temps within a narrow range for good tent performance. It is not a bulk 1500 watt room heater repurposed for the task.
Variance in temp and heat slow growth in a tent. Get your lung room up with one of these
https://www.google.com/search?q=roo...0UVBvYnJmc1FJXzUYATABOAEg0o75nwNKCBACGAEgASgB
And get the room 3 degrees under where you want your tent or maybe even less depending on your heat load for the lights
After you grow for a while you will find that the heater load on your system goes down as you run your lights higher. By the time I am in veg the heaters are off due to high light use ( 700 watts ) but the dehumidifiers are on and they take even more energy than the heaters.

One other suggestion for your heater. My basement hangs between 63 and 65 degrees. I did not have a heater for the room the first grow. I took advantage of one of those rules of the universe to help my little heater box.
Heat rises. I had my ACI box on the floor drawing in 63 degree air.
So I put the box on top of the tent. Heat rises and the temp of the air was 6 degrees more than the floor. This helped loads but in the end I did get a room heater for the grow room.
