Tube heaters are good for small spaces when you don't require kilowatts of heat. But if you require kilowatts of heat then oil filled rads would be cheaper to buy .

All heaters are 100% efficient

Yeah, i dont think they would be good when intake air would be 32f (0c), the exhaust will need to run on very low and voila humidity problem. Although im thinking about other place to grow than OP, i think its best to heat lung room - saw oil ones with thermostat for air that controlls also wattage use

Sorry, I read that as room. I believe they would be too much for a tent. That said, I have seen a few people using a low profile plate heater that may actually be an oil filled radiator, just smaller for inside the tent. Very small footprint and very low fire hazard.

ETA: Something like this

Whats the lowest temperature you have outside ur tent ? Im wondering if its possible to have 32 F outside and heat up inside

I have no idea what 32F is off the top of my head. I suppose it gets down to about 5C in winter. I use it when the lights are off. If it gets a bit cool when the lights are on I have a little 80w green house heater that kicks in as needed.

32F is about 5c, so yeah this is temperature im going to deal with and im trying to figure out is lung room heating is necesarry or heating only tent will work. I saw one oil heater that have thermostat for room temperature but most have thermostat for just the heater

I just check and 32F is actually 0C, which is way colder than 5C. Why people use the Fahrenheit scale is beyond me, it is way too confusing.
