Space heater more harm than good?
#26356367 - 12/01/19 10:07 PM (4 years, 1 month ago) |

I bought a space heater because my place gets cold, especially at night (day time ~65F and at night closer to 50). My jars and agar dishes have been colonizing pretty slowly and I am assuming the cold temperature is why. Is using a space heater to bring up the temps to mid 70s going to negatively affect a my grow? Ive read RH isnt a huge deal for jars but I guess I am more concerned about when I go to fruit and having my tubs dry out, is there anything I could do to keep RH up while running said space heater?

Just mist if your shit looks dry. And don’t point the heater near your setup, point it in a different direction and just keep an eye on your overall temperature and you should be fine. You planning on a monotub or what? As long as your tub is set up right you shouldn’t have to worry about humidity.

Damn son, your gonna use a space heater to bring the temp up 20 some degrees in one room for 2-3 months?
That's gonna be expensive as fuk! Why not just be more comfortable in your house and set the thermostat to 70?

A space heater isn't that expensive if you dont have a huge room and perhaps take extra steps to contain the heat. I use one in my garage grow area which is plastic wrapped around shelves like a tent/greenhouse type room. The unit barely has to run when set up properly. Helps when the cars pull in with hot engines of course, but just be smart about it.
Set it so you maintain ~72°F. Mine is set to 67°F but thats the lowest the temp in the whole space gets, if even. When it kicks on my thermometer reads like 78°F.

The heater in this place sucks. I basically live in a house that has been converted into multiple different units so its not central heating. But electricity is not a problem because all our utilities are included in rent plus our place has solar panels

Yeah I do not plan to run it 24/7, just as needed. So you don't have any problems with dry air running yours?

Nah thats what the tubs are for. Moisture doesn't really squeeze out a closed tub too easily. Healthy spawn and properly hydrated coir is all you gotta worry about. Not too wet, and not too dry. I do like the drier coir prep then a thin top layer at spawning with a healthy misting before closing the lid until harvest. Check out shaperdreamings coir prep for the misting tek and bods hydration ratio is great. Follow his ratio by weight then mist like she does and leave it be.

space heater dry shit up..
I suggest a oil burner/heater.. It does not destory the relative humidity as much..
if you want to really boss up, get a cool mist humidifier, put it on a timer. the enhanced evaporation rate you get with the cool mist cycling off then off while the heater is on may give you incredible results you would otherwise miss out on, like bigger yields.

Why would oil radiators not fuck the RH as much as ceramic element heaters? I know oul is more efficient.

because it's not pulling humid air through it's heating element and blowing it out.. that process pull in moist air and blow out dry air.

Makes sense, though that may be the case, but there where does the moisture go? There's no reservoir pool. Seems like its in then back out.

It evaporates into dry air while crossing over the ceramic heat exchange element i assume..
infrared and especially oil heaters are advertised commercially as better than ceramic space heaters because they don't dry out the air as much.

The humidity in air is already "evaporated"
The humidity lowers when air heats up because hot air can hold more water. That's why its relative humidity. If air is 100% RH and you raise the temperature the RH will lower.
A forced air heater tends to dry out tubs faster because of the air movement not because of the humidity drop.
Both a radiator or forced air heater will lower RH the same per given temperature rise. Its not like a forced air heater destroys water molecules and the radiator doesn't.

I agree the water cant just disappear from the air, its already evaporated and it certainly isnt condensing from being heated. I don't think it really makes it dryer in the room, hot air holds more moisture than cold air, which is why dehumidifiers use cooling coils to condense water from the air. I'd assume what makes it feel dryer is the fact that the warmer air in the room can now absorb more moisture, like your sinuses eyes and lips making you think its really dry in the room. Just my opinion not factual at all, i still went with an oil heater because theyre more efficient. And why risk making it dryer if it is an actual thing.
edit just read the post above mine, basically the same thing said.

So if we use a heater and want to humidify the room extra then simply a wet sponge or tub o pwrlite could slowly add moisture right?

Buy a humidifier  When i lived with my dad we had water radiator heating through the house (simular to the electric oil filled heaters were talking about) He would just put a pot of distilled water on it and the warmth would help it evaporate in the room. Just an idea,

Well I'm not gonna drop money on a humidifier or anything else really unti around February fue to budget constraints. Insurance and Lockn take priority .
Anyway, you made a great case for just using a wet bowl. I have a ceramic digital heater in small space in a tented shelving room in the corner of the garage. Don't really need the extra moisture honestly since I can just adjust my coir prep, but was kinda thinking out loud i suppose.

just the process of the fan blowing air across the ceramic heating element/exchanger drops the rh in room more than a oil heater.
moist air don't run across heating elements and evaporate air of the same humidity, it exchange air of higher rh with with dryer air. you can look up any heater buying guide, they even advertise those oil heaters as much better for your health, since they don't dry the air out as much.

Convection ovens vs conventional ovens. Same temp one cooks faster. Air flow transfers heat better. Dries out tubs faster using a fan forced heater. But with a given raise in temperature with no added moisture to the system both heaters lower RH the same amount per temperature raise. Buy a warm mist humidifier or put a wet towel sponge etc by your space heater

On a side note, how effective would using a convection over to dehydrate mush be? Obviously I have my dehydrator and would only intend to build a cabinet with spare parts from my defunct units, but I always wondered.

Just check amazon for a temperature control thingy. They are like 50 bucks and u def need one or the space heater will kill your shit. U will also need a basic humidifier to just be running the room the whole time. There are even fancy controllers that do humidity and heat but I wouldnt worry about it. Just having the humidifier going is enough. U need the temperature controller tho. THere are modern ones for 50 bucks.
WARNING:: MAKE SURE IT SUPPORTS YOUR HEATER TYPE OR ULL SET A FIRE. ALSO MAKE SURE YOUR HEATER TURNS ON AUTOMATICALLY WHEN POWER IS APPLIED>

My space heater is digital with automatic shutoff system. Fan drying is bullshit and I was discussing convection oven which blows the heat around, not convnentional ovens. Sublimaez you got some reading to do, seems you're misinformed.

Definitely make sure your heater has a thermostat or use an external one. Many years ago I once had a whole room full of tubs about to harvest and my heater accidentally got left on high overnight. When I woke up and went in to harvest it was 118 degrees F in there and my mushies were blueish black oozing blobs. My entire grow went into the compost pile and I cried like a little kid. Don't do that.

I had the same situation as the Digit user, I was very upset when I made such a mistake. So I decided to buy a new heater that will have a timer so that I can set the time when it should turn off. I couldn't choose for a long time, but I found reviews here https://buyersimpact.co.uk/ which helped me make my choice. I really liked the Taotronics tt-he001 heater because its price was low. What kind of heaters do you use?

Ambient temps of the room are what's important. heat the room not the tub. 70-73f is perfect for cubes, space heater does not matter as long as it keeps the grow area warm and its not directed at your myc. Otherwise don't trip, unless you've eaten mushrooms, then enjoy.
