Finally, an effective and SAFE grow tent heater

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 have been kicking around getting both the humidifier and the heater in the Infinity line. I just wish I could sub the inkbird sensors for the Infinity units. Currently I use a cool mist humidifier and 2 heat lamps on a controller that is not wifi controlled but very close to +-1% for both.

I drank the AC Infinity Koolaid a couple of years ago and have zero regrets. I started with Pulse + Inkbird + no name humidifier but retired that gear as AC Infinity products became available. Their C69 Pro + is running two fans, an inline fan, the heater, and their humidifier, and, via an on/off adapter, a Phol Schmitt dehumidifier in the tent.

The only significant item I've got that's not from them is my lights. I use Growcraft veg and flower lights. Unlike most of their products, I their lights don't compare well with offerings from many other companies.

Have you looked into their Terraformer? It's been "Sold Out" for months so it might end up being vaporware but, if they ever get it back in stock, it will be a game changer for a lot of growers.

I agree about the lights. I like most of their equipment and they seem like excellent quality items. I’m really intrigued by the Terraform 7….looks like it does everything you could possibly need (AC, Heat, Dehumidifier). Thats one item where I don’t want to be the beta tester, but if it ends up getting good reviews it could be difficult to pass up. It’s also more than I’m willing to spend at $599…..but a very interesting invention. I only grow in winter in a cold basement, so I have little need for AC at the moment. I’m still lacking a good dehumidifier plan for flower though.

I feel the same way about the new artificial intelligence controller that is arriving next month….sounds amazing but I’ll let other people work out the kinks. I dealt with several hiccups when AC Infinity first released the WiFi Controller 69, especially involving automatic updates.

I’m sold on this heater though….it works well, it’s safe and it’s reasonably priced. When used in conjunction with the humidifier, hitting a stable VPD is proving easy.

Looks good and price is right.

I can't find information on power consumption.

Any ideas on the range of wattage from running it minimum to full power?

So the actual AC infinity website doesn't show it, as far as I can see..

But on or the uk distributors taking pre orders states at max power it's 530w.

Incidentally for anyone my side of the pond, the ac infinity site has them on sale for £75 but there's a small tax takes it to £82.. but shipping is £70 on top.

You can get them on pre order for £129 here but probably some delivery costs.

All I see is that it runs at 530 watts at full power and there are ten power levels. Since I’m only heating a small 2x4x8, mine is normally running at level 2-3.

It's a lovely bit of kit.
Long overdue idea too.
Certainly help in my basement which I was thinking of shutting down for winter.
Seriously considering getting one.

I like the propane heaters with a built in thermostat and lighter function during winter months. It adds a lot of beneficial CO2. But you can only have that in a lung room and not the actual tent.

Both units ( heatbox and 15L humidifier ) installed and running in auto mode. Using the vivosun app to monitor. Temp is about the same as the inkbird controller and heat lamps But I am flat out amazed at the stability of the humidifier. I can turn my duct fan on 7 the tent sides suck in a small black hole formed and.... I mean it can keep up with the duct fan on 7 constant. I am doing 1 on 2 off at 3. also blocked one way duct in upper/lower panel so the hydrobuckets will stay more stable.
This investment is almost what I paid for the whole tent kit on prime day and looks to me money well spent.
Tent looks so clean. Only things in it are a plant and IPM stuff.
I now have 4 monitors for systems but only the vivosun is mobile.

Wee like heat lung
You could get a 250 hps in say a propagation tent put a duct coming out the roof of it csuse warm air rises
Duct it into the tent
Or spend a bit extra on your heating bill put your heating on a thermostat if you can do that

Update on ac infinity system.
Went ahead and purchased the 69 pro controller. Just like the vivosun controller it does stuff that is not logical or intuitive.
The major issue with controlling the humidity is setting your maximum and minimum targets and using buffering setting. If you use a high max setting the hose gathers condensate and the humidity blows past the settings. I set the max at 4 and it controls within 1%
The heater has been problematic but due to an old issue I sometimes have. It is know as RTFM itis. I seemed to have some problems with it shutting off. Finally asked the internet and AC infinity answered the question. The unit has a tip over sensor that is very sensitive. If you move the unit at all it shuts down but the controller does not tell you or the warning icon does not make sense on the screen. I had been moving and adjusting the temp and reconnecting cables and all the time operator error was just stressing me out. In addition I would caution anyone running the humidifier in vdp mode. If your heater goes nuts and does not shut down it will still set up for .8 vdp. At 81 degrees it spiked the humidity and wet all the walls in 10 minutes. This happend after I inadvertly bumped the all button and had not zeroed the numbers. If you hit that button factory setting was 192 degrees and 32 degrees low. LOL wow what a mess.
Overall it is a standard device manual written not by a technical writer but an engineer who knows it front and back which is the most gawdawful way to write a manual.

Here's some more feedback.
I have a 2x4x8 (little bigger than that) tent in the basement. It's cold down there... 58* or less.
With lights off it can NOT keep it very warm... about 73* max. I here ya... that ain't too bad. Well, it's like a shower in there, almost the ENTIRE inside has condensation on the surface. The combo of cold outside air and humid/warm inside air makes it rain in there. I can actually keep the VPD under control pretty well, but I can't get rid of the humidity and have hot air. It's one or the other.
So I decided to pull the AC Infinity heater and put in a Amazon cheapo with on/off control via an ACI outlet controller. Even on low setting, I can hit 83* in minutes. It cycles more than I would want, but it's more than enough power to get that tent heated up and MAYBE it will help dry it out. We'll see in the next couple days.
I have a 4x4 where it's pretty normal temps.. cold is 69*, and the AC heater doesn't have any problems keeping it where I want it. VERY steady too.

I agree with you on their vpd mode and manual.
I had no luck using the vpd mode. I do love being able to set the leaf temp offset and monitor vpd right next to temp and humidity.
Their manual is awful. The only way to figure things out is to just start using it and manually tweak settings until you get the results you want. Once you get it dialed in though temp, humidity and vpd are very stable.

Curious as to how you came up with a value for the leaf offset. What procedure did you use to determine temp difference. What tools. I have seen the data but I am unable to develop a strategy where the numbers are clear.

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.
