New grower Heating grow tent
I’ve been getting ready to pop my first seeds for my first grow in a 4x4 loft tent setup but I’ve been trying to dial in my environment first to avoid anything unexpected.
I’m using leds and living soil so from what I’ve seen I want it slightly warmer than a hps setup so I’m trying to keep it at around 28-30c at the moment. I have a small oil rad on an InkBird set to 28c.
The only thing I’m finding is that temps tend to constantly be heated up and then drop off so the radiators being turned on/off every 30 mins or so. Is this the way to go about it or is there a way to achieve a more consistent temperature? (My fans are are temp controlled to, pulling air from inside the house).
The only other thing I was wondering was night time temps. Should I pop the radiator on a timer to turn off at lights off or keep everything at a set temperature?
Appreciate any pointers 🙏
@yoshi Good question mate!
An oil rad is best, but you have it a bit high. try 26c for day time temps and around 21 for night time temps.
Dont be too strict with it though, the plant will be fine around those levels, just keep it consitant if you can.
There are some heat mats you can get for the side of the walls and stuff, they help too, but your best friend is insulations. You want to try nd keep the heat in for as long as possible.
You have the inkbird, so it should do all the work for you, but reducing the speed of extraction so the air isnt pulled out so quickly would work too. But the way you have it now is good, just a pain in the arse with the radiator turning on and off all the time lol
Get some Earthwool, like Rockwool but not itchy and cover your tent with it and then cover that with a sheet/blanket/quilt etc. possibly wont even need a heater 😉
@macky thanks mate I was wondering how I can control the night temps as the InkBird only lets me set one target temp, or am I missing something like a dual setting?
I’ll try turning the temps down a bit to.
I’ve got the fans set to be on the lowest setting that that gives me negative pressure, then they just ramp up if it gets too hot removed link
I’ve got it insulted like crazy up there haha. Before I had the heater it was pretty consistent just not warm enough really.
@zn thanks mate I’ve already done that. I’ve also got super quilts on the rafters and insulated under the floor. 👍
In that case set your heater for about 20-22°C then, oil rads tend to keep heat quite well so should minimise constant on/off

My Inkbird (model ITC-306T) has 2 settings per 24 hours, one for day and one for night. Some growers like cooler temps at night to mimic nature and claim better growth. A quick surf on the internet and you will see many different views and opinions on this subject. 😎
We just smiled n waved sittn there on that sack o seeds
@hart ahh ok thanks for that. So it looks like there are 3 models of the InkBird and I have the itc-308 which doesn’t allow day and night settings just a constant temperature.
I think it looks like you can do this on your version and by setting up a schedule on the WiFi version.
Thanks for that info though. I might look into the WiFi one just to be able to monitor from outside the house 👍
@yoshi hi mate, I’ve ran into similar problems as you growing in a shed, it’s a constant battle to try keep everything stable. Big downside in a small grow is the air your heating is gone so quick through extraction so an endless cycle.
If your pulling air from inside the house and have the tent well insulated not much more you can do.
My highest temps in the winter without having the heater going nearby non stop was probably 24 and the plants done ok, try have your lights on at the coldest part of the day to help with lights off temps. You’ll find that sweet spot that works for you, without costing the earth to run 👍🏻
Does your rad have a heat control on , if it's set to max basically it's going to come by the inkbird get really hot then switch off, temperature drops then the whole process starts again. If you can turn it down so it will maintain a happy temperature and stay within the range set
Genesis 1:29-God said, “Look, I have given you all the plants that have grain for seeds and all the trees whose fruits have seeds in them. They will be food for you.
@dobbin I think it’s more of a thermostat but than a heat control on the rad as I started with it on full and then I turned it down and it didn’t really seem to change anything 🤷♂️
If you started on full and then turned it down, the heater was still at max heat so wouldnt do anything until it dropped below that...the thermostat will measure heat of oil in rad, not always a good thing as competing Inkbird is measuring air temp...there will be a balance somewhere, depending on accuracy of thermostat in oil rad...you'll find it 😉
Can you post a pic of your tent or area and a pic of where the rad is? I'm keeping a room consistent temps with inkbird and 600 watt rad. Does your fan controller have a max speed setting?
