Finally, an effective and SAFE grow tent heater

[LewberDewber852]

My humidifier doesn’t shutoff at the set. I can set my low target at 45 and it’s still 70% in there. I really hate exhausting out my climate if I don’t have to. Would an humidity controller inkbird combat this? I think I have the cloudforge 3.
My oil radiant jobber does amazing on a inkbird and I’m in a basement with an under utilized 5x5. Thing was like 30-40$ at Lowe’s. All analog so pairs well with the inkbird.

I have my humidifier set up in auto mode, target, continuous 24/7". In target rather than trigger mode you only have the option of setting the on/off humidity level. I have the min/max settings at 3 and 5.
My tent temp is set at 79 and humidity target at 74%. With a -1 degree offset my average vpd is 0.73.
I should also add I'm doing this through the 79 Pro not the humidifier's onboard panel.

I'm using an infrared laser thermometer that are available from amazon. Shoot several leaves to get an average temp. Subtract from room temp, if using leds, to get the offset. I didn't buy the most expensive one but it ballparks it close enough I think.

Ok now here is the important part of the equation. You have an air sensor that works on resistance and a infrared that looks at radiated energy. How were the tools zeroed to express a very small difference in temp?
As a long time automotive tech I have worked with temp all my life. I have several high end tools that measure temp from -35 to 1600 degrees. my main tool is a fluke 88 with a $700 pyro kit that measure very broad but very acurately. air moving over a probe and a leaf will change temps. All my plants rock indicating wind over the leafs. It seems to me that measuring the leaf temp os not something I can do in a tent with all the movement and up and down with humidity. I honestly had a closer to spec humidity range when I used bowls of water and wet towels. This humidifier no matter where I put it has a 3% range swing. Only way I can get it more stable is to reduce duct and the 3 fans in the tent ( 2 in the lights) to almost no air exchange.
Frustrating to say the least.

Yea the pro is the difference maker. The onboard panel of the humidifier itself is what I’m working with since my controller (Old 67 model) is now basically obsolete bc it has no WiFi. I’d imagine they prolly have an adapter tho. That 79 pro looks tits. I’ll have to grab one of them for Christmas

In a perfect world I’d feel the only time your exhaust should come on is to exchange the air rather than come on when limits are exceeded. I say this bc it’s wasteful to exhaust the climate you’re trying to create. Which is what I’m currently doing

3% humidity swings is where I'm at too, 2% above and 1% below.
I don't honestly know how accurate any of this is. It certainly not laboratory grade accuracy. After all it's a very dynamic environment inside a grow tent or room almost like outside in mother nature. Plants can adapt to and deal with these variations.
I think it gets me close but ultimately it's how the plants are responding that is important. What I've noticed, with having data to look back at, is that every time I open the tent is when the most dramatic swings occur. By being able to monitor and make adjustments without opening the tent as much I have a much more stable environment.

I totally agree! This is probably the advantage of having a dedicated lung room to house your tent or tents.

Hello Rollitup,
As we move into winter, I am assuming that I’m not alone looking for heating solutions for my tent. I looked for a safe heating solution for many years but always hesitated because space heaters in a tent appeared unsafe. I discovered this AC Infinity heater that can be set up outside of the tent and it pumps warm air through a hose. It’s been a game changer for my basement tent. For anyone struggling with cold tent temperatures, I highly recommend this unit. I run mine using an AC Infinity Controller 69, but the unit can be programmed on its own if you’re not using the AC Infinity system. It’s under $100 currently.

Between their humidifier and heater, I’ve managed to lock in my VPD. I’m at 78 degrees/65 % humidity with lights on and 73 degrees/63% humidity at night. Meanwhile my basement is 67 degrees at night.

Best of luck with your grows……I hope this information proves helpful to someone.

I really like AC Infinity's approach. All their stuff fits together and you can build up the system one piece at a time if needed. I just bought one of their 6" exhaust fans and I already own one of the 16" Ion Beam side light systems. What really brought me to them was their clip on oscillating fans. I have two of the original ones that made noise, but they replaced them for free and told me to keep the old ones! That's admirable!

You’re totally right. Something I’ve should’ve done by now but haven’t for no good reason. Same with a dedicated panel. Not that I am pushing any limits but peace of mind is just that.

It is convenient that’s for sure. I like the little books that come with their products lol
Makes you want more shiny things to optimize your environment and experience

Mine caught fire and I've had support try to tell me all the equipment sold on Amazon by the seller "AC Infinity" is second hand lol.

I honestly was going to mention to buy anybody’s equipment at your local “hydro” store. Usually just as good as any deals you find online and if u have an issue so much easier to deal with.
I had a good experience with their customer service when my first cloudforge wasn’t working right. Luckily I bought it from my local shop
They sent me the next gen model at the time.
