Temperatures in my area aren’t crazy cold usually but sometimes they do get freezing. West Texas. Weather/temperature can change within minutes here.
I will be running my lights in evening/night when temps are colder so they will heat the tent some, hopefully I wouldn’t need to use a heater most of the time.
I will run it on a temperature controlled outlet so it only turns the heater on when it gets below a certain temp.
If I can use a heater like the one in the screenshot where would I position it? If that one is not acceptable, what kind of heater is? And where can I find one that is suitable for small space of 3’x3’x5’? My budget is low. Thank you!
I use a chicken coop/brooder radiant heater when they’re young and my AC is on…once the heat kicks on my temps are good and the heater goes back to my coop.
You are gonna want some airflow inside your grow space.
Do you currently have a plant in your growspace?
Plants and soil will add humidity how much depends on alot but it will bump you up. Humidity isnt CRUCIAL to success but having it in peramiters is important enough. You want to be at about 65%+/- for veg and 55%+/- for flower. These are safe numbers and fairly easy to maintain. What are you working with?
Airflow and ventilation are gonna HELP prevent alot of stuff from flying bugs to mold and mildew so must figure something out for both.
Be cautious of putting any heater inside your tent. Firehazard #1 and #2 u have to sacrafice floor space to it.
You dont want a fan blasting super hot air at your plant. The heat needs to radiate off of the heater vs be blown around. My light gives off alot of heat and its even an led…what kinda light you got goin? I have a 280 watt for my 3x3 and it keeps it well above peramiter, without vent fan my tent would be easily 90 degrees or more.
Would you be willing to show your growspace maybe share your equipment list. Might be able to hammer out some of your environmental issues with more info.
@Docnraq the moment I run any fan even slowed down to it’s slowest setting humidity drops to 25% or lower. my area is extreme dry. This is even with running only one fan slow enough that the blades are barely spinning.
My lights will be running during temps that might get below freezing, do you think the lights will still produce enough heat without the help of a heater occasionally?
What do you guys think of this type of heat element? I’ve read on other forums of people using these in their tents. If you put a fan next to it it would spread the heat.
Where would be the best location winin the tent/proximity to the plants to put this?
I am ordering a seedling heat mat also; what is the best position/way to use that? When not using it for seedlings, can the mat be positioned somewhere near the plant to provide it with extra heat it needed?
Whatever heat elements are installed, they will be controlled by a plug that will power them on and off when temperatures reach desired levels. Most of the time the LEDs should provide enough heat, but I want heaters ready to go in case it does get too cold. I work a lot and can’t always be there to check up on things.
That means your humidifiers don’t produce enough mL/h. What’s their output?
The specs for those radiant heaters reference a 23" x 16" x 16" (3.4 ft^3) volume. Yours is 13X larger so, if you want to raise its temp by 10° F, you’ll need 6 or 7 of the 150W units. Position them so the things you want heated have a direct line of sight to one or more. Those things needn’t all be plants. The tent, for example, will absorb heat and then radiate it.
The heating mat can be used, of course, but I doubt it will make a noticeable difference.
I gather your tent is in a part of your house that isn’t serviced by HVAC(?)
No. And with sub freezing temps your gonna need heat during lights out. You could grow auto’s in a 24 hour light cycle to avoid the cooling of darkness. Not sure the reptile warmer will do the job. Its not designed to heat such a large space. Want a space heater large enough to heat a 9 square foot space up to 75-80 degrees.
I get dry, I live in AZ. You are gonna need a humidifier in this low humidity environment. How are you planning handling air exchange?
This is the heater you want, designed and fit for purpose…
An electric tubular heater ensures your greenhouse can be used throughout the year, whatever the weather. They are made from steel, powder coated in white, and are designed to provide steady background heat, as economically as possible.
Although there are several types of heating methods suitable for greenhouses, warm gentle radiant heating in our opinion is one of the most suitable and economical for the typical greenhouse enthusiast. Unlike other tubular heaters, this one comes with a thermostat. It is comparatively cheap to install, can easily be moved and provides frost protection and low background heat.
These heaters are designed to provide a gentle radiant heat within a 1 m radius. The surface temperature of the 35 cm heater will reach approximately 50°C at the highest setting, and the 95 cm heater will reach approximately 85°C. The temperature increase in your greenhouse will vary significantly depending on the size of your space, how well insulated your space is, and the outside temperature.
