Growing in unheated garage

Well my experience has been different so I'll go by what I have personally experienced. I even posted pictures but apparently that's not good enough. I can keep the inside of my tent at 65F during lights off in the winter when the temps get cold in an unheated garage. That's without under floor heating and just a radiator inside. I did the same thing last year but had the plants sitting on the floor so the root zone was too cold and it effected the growth of the plants. That's why I put a raised floor in my tent. This thread wasn't about whether or not I could keep the tent warm enough because I can, it was about raising the plants off of a cold concrete slab. This winter that's not going to happen because I have gotten them off the cold floor.If growing in 45f temps were as easy as undrfloor tent heating and sticking a radiator in there then why the fuck are we all not doing this?
Probably because this dosent work
And in the summer I'm able to keep the temps under 80F during lights on when the temp in the garage is 90F or more using a portable air conditioner inside the tent. It is possible to effectively adjust the temperature inside a tent when the outside temperature is much higher or lower.

Ya with very low extraction where heat generated exceeds heat lost in air volume. Theres no argument but to increase futher is tricky.
I dont vote underfloor heating but a few inches of top quality insulation, keep the heat in not try to warm large volumes of soil with thin low watt heat strips.
I have experience of heat mats, either too hot or not enough heat to heat more than a small pot over time.
There are closed extraction runs with dehumidifiers to keep more heat, imo it gets too tricky but im not in that position so i hope you find those extra degrees

Also I dont like the idea of running space heater in tent. I did it years back for only a few days. Because it tended to heat stress the plants, and dry out pots way to fast.

We have already discussed that you are weak at both growing and science, ya you can grow but your input and pics here do very little but create argument.
Ya growing in a cold room can be done, is it advisable....No, does mere underfloor heating bring you back up to the temperate conditions needed.....No. Does extraction extract heat.....Yes.
You are left with shortcuts, run low extraction, conserve heat, pay loads for heating a tent every cycle and so forth.....
Add somthing or stop being argumentative

It's cheaper to heat a 4 x 4 tent than an entire garage.We have already discussed that you are weak at both growing and science, ya you can grow but your input and pics here do very little but create argument.

i guess it depends on how cold it gets in the garage, and how well insulated the box is. it's not an optimal scenario, but if you have no other place, it can be done. you'd be better off in the corner of the basement, or in a fair sized closet, but if those places aren't available, you can make the garage work. if smell isn't an issue, vent the tent into the garage. it won't bring it up to good temps, but heat is heat, if you don't dump it outside, it's got to raise the temp in the garage a little. try not to keep opening the door, look at it a couple of times a day, otherwise, keep it zipped up to retain the heat

I was thinking about doing something similar to insulate the tent more. In fact I don't know why I haven't done it yet.

There's 1" insulation round the sides, a couple of those insulated camping rolls, some silver bubble insulation foil, bubble wrap, a woollen blanket my ma knitted about 30 yrs ago lol
Works a treat!
Pots work like a heatsink and I water with warmish water

The wattage of your light would heat a garage if converted to an efficient heater, as such it heats at best a small area of air that is easily lost to extraction.
Then you place a heat mat and heater in there and tell me this is cheaper.
How bigs your garage bro and how cheap ass is its insulation, guessing there more at play than just the simple.....!

Don't flame me, but here is my suggestion, and you'll get more yield. Hear me out...
Change over to hid for the heat.
Run two tents. 12/12 so when one tent is up the other tent is asleep.
The awake tent vents through the asleep tent, keeping the asleep tent warm.
HID lighting is cheap, and you are already throwing electricity away in heat.
People run led to get rid of heat, you need it in this scenario.

It's 20' x 20' or 400 square feet. The ceiling and sides are insulated it's the metal automatic garage door that has no insulation and isn't sealed very well. Then the concrete pad for the floor acts like a refrigerator unit. I can't cover the pad because we do park our cars inside during the winter. The house doesn't have central heating so I cant tie in to any existing ducting or anything and would have to retrofit the garage with a heating unit which would cost more than I want to spend. I'm in Oregon and we have pretty mild winters so I only have to deal with extreme cold for a couple of months.
I agree that the situation is not ideal but I'm making it work.

I do run HID's. I run the lights at night and the temps are fine. During the day when lights are off the heater keeps it warm enough.
But the point of this thread was to show how I got my plants off of the cold floor. Even though the temp in the tent was okay the floor the plants were sitting on was 50F and the root zone was staying too cold. Cold roots in soil is not good.

Ok, I saw the other guy's pic and thought it was yours for a sec.

Quite a size then, i guess you stuck with fixes and like i lets hope it is a mild winter.
As your already growing i can only assume anything will increase the success.
Quite pricey but there are some insulated sealed garage doors if the future is looking like your stuck in there.
If the wife is bitchin you might get that garage kitted out, warm, a bed, tv, small fridge and along with your plants if the wife ever kicks you out you got a sweet place to chill in till she gets over it
