I watched a video that stated 55 gallon drums tend to separate into a warm upper layer and a cold lower. To combat this I put a 75w aquarium heater in the bottom and sealed it with the lid as to contain it and not affect humidity keeping it warm throughout. During the day the heater automatically turns off and absorbs the ambient heat. If the water drop below 80F the heater maintains the temperature providing a 70-80F large thermal mass to get you through the night. I have 2 in a 10x12 however, this is not the only method I use because although not dying at 40-50F plants tend to slow down and look sickly if sustained at those temps. This is a timely topic heading into the coldest part of the year. I rewatched the mr.heater video on this channel yesterday for ideas on this matter.
Hey, Brad, I just discovered your channel! We have a small 6'x6' unheated greenhouse. I saved 6 of my big cat litter jugs (20 lb size), painted them black, and filled them with water. On a sunny day, I'll set them in direct sun, then move into the greenhouse before dusk. They keep the greenhouse about 5-10 degrees warmer than outside air - within reason. I'm in the northern third of Indiana, so these don't work when it's 18 degrees outside, but they're excellent in Spring when temps may drop to high 20's-low 30's overnight. I may experiment this Spring with one of those small cube heaters w/thermostat. Beats worrying about my greenhouse temps. We grow a sizable veggie garden which feeds us all summer, then we can or dehydrate to eat all winter. Keeping those warm-weather seedlings healthy is a must. The small oscillating fan is something I need! Thank you for the ideas!
Thank you, we were in the 20's last night and filled jugs with hot water and my mini greenhouse stayed frost free where the night before the zipper was frozen shut. Have a blessed day! You can also use a fish tank heater submerged in a jug or bucket of water. Just check the size 1-5 gallon to know what size bucket of jug you need.
A clay chimney pot or large clay pot over the candles acts as a a thermal storehouse and increases the heat output from the candles. Best placed low down near the floor to allow the heat to rise.
Keeping the attached porch (turned into greenhouse) above freezing will allow us to grow lettuce, spinach and cold weather crops this year for the family. Not worried about producing for the public any more. Lost farm fields of collards and kale last Dec in an abnormal freeze. Thank you!
I'm planning to set a couple of jugs of water on top of a seedling heat mat connected to the thermo plug. Should help to evenly radiate heat. Thanks for the tips!
Have you looked into window shrink film? The clear kind you install with two-sided tape on the frame and using a hair dryer? It's done a huge difference for me, without losing light intensity like you do with bubble wrap.
That is a great topic and idea. I did try it once but it didn't work well for me, not sure what I did wrong and it was really labour intensive. I use the same pieces of bubble wrap year after year, so they are pre-cut and stored in my basement all summer. takes me 10 minutes to get them up these days lol.
Bales hay or straw sitting outside help. In light freeze weather. I have never tried in heavy freezes with lots of snow. I would imagine a thermal water proof moving blanket on top, with a tarp over to help keep moisture off would help.take care.
i have an itty bitty green house. i use my canning pot, with an inch of water, place the candles (large ones) into clay pots then in the pan. works a treat. buts a small space. warms to 65 for about 5 hours.
I used my bbq smoker to heat my greenhouse. My smoker does the heating and the cooking . The Oklahoma Joe Smoker work great. My greenhouse serve as trellis, greenhouse and playhouse.
Actually I use 30 gal. Barrels filled with River Rock then topped off with water. So the Rocks hold the heat for approximately 6 hours.But then my Greenhouse is 10’x14’ RIGA4. So it’s at got a bit of insulation. In order to use the Candles cover them elevated with bricks then clay pots.
If you use terracotta pots or put on in the middle of a metal coffee container, it will trap more heat, get warmer and radiate enough to warm up the place. if using the terracotta pot method, place a few blocks around the candle, and place the pot bottom up on the blocks so that is just a bit (maybe an inch or two) above the top of the candle and just let it go 😎😎
My primary heat source is a Comfort Zone heater! They are pretty efficient and powerful heaters, and it doesnt need to run constantly either. Love it! I supplement by bubblewrapping
Use white barrels and paint them black put in the corners of the green house and fill with water. Will do the same as the bottles. Put a self across the top and can double as a shelf. Also can be used as a water source if not luck enough to have running water in the green house. Then put your most tender around the barrels. Will have to start heating the water barrels before it gets cold as that much water will take time to warm..
What brand of window is that? I had windows like that but a truck hit my house and I couldn't find out what brand it was to get the insurance to replace it.
Thanks for the great tips. I could use some of these as we do get freezing temps at times. I think I've seen that video with the giant stove haha. Yeah it's too much. I love soda. Those bottles are helpful for so many things.
I started my greenhouse the same week as when you made your new one in 2014 god damn 6 years this March god that’s gone too quick haha I stayed heating mine then and haven’t luckily had any problems , Altho the tutorial I followed was one you made in 2013/14 I think 😂😂
I have used this method for the last 2 years in 55g drums although not my primary source (electric heater) it’s my most efficient method. Along with others depending on the severity of cold. I left another comment with more details before reading this on this video.
The ONLY 100% FREE method is mulch. A bare ground addition to a home can be made into a growspace That can be accomplished with mulch. If it holds moisture and if the right thickness is maintained adding a layer every two weeks. Kept moist this mulch breaks down and creates HEAT.
add alfalfa pellets to your mulch and that will super heat the mulch. scatter the pellets between each layer of mulch. alfalfa will also super heat a compost pile when used in the nitrogen layer
I use larger candles, pint jar size and turn a clay pot upside down over the candle, put small spacers under the clay pot so air can flow upward as the heat rises from the heated clay pot. if the candle will not stay lit make the hole in the bottom of the pot larger to allow more airflow. fill a clay pot with small gravel or rocks or sand and place it in front of the ceramic heater, the pot heats up and gives off more heat. you can also use glass jars or gallon tin cans, or metal pots from the kitchen filled with water in front of the heater. use water containers that will fit in your microwave and reheat the same water each night in the microwave. my ceramic heaters are on timers and come on and go off at designated times. put your seedling heat mats in a seedling tray and fill with sand or pea gravel to obtain more heat.

THIS IS AN EXCELLENT VIDEO! my plants and I thank you for all the ideas!!!!!!!! ❄️🌼🌻🌿🌱
You can also use a small clay pot with steel wool over a 40 watt bulb lamp. The bulbs die kinda fast but they are cheap and it works great!
Cool idea!

Hi, Brad! Thank you for sharing all this useful information. Can I ask you about your experience in protecting your garden from heavy downpours?
good drainage helps, a lot of the non native plants get moved under cover if they are sensitive

definitely! I did that in a video years ago

yes, mine is electric heat as well
You could combine them aswell. Like putting the water bottle above the candles.
totally!
its 80w a candle and it takes about 58 or 60 w to heat a 10x10x10 room 1 degree Fahrenheit
A hot water bottle! I would've never bloody thought of that, thank god I'm subscribed XD

Loved this!! 👍🏻😊👍🏻
Thanks a million!!
Thanks a million Sir...man...some really great ideas....never saw a thermal cube before...super cool idea👏👏👏👏👏
Where are you located? Plant zone?
This is a great video. I'm zone 7 Delaware. Now I just need the greenhouse!
Thanks!
What brand of window is that? I had windows like that but a truck hit my house and I couldn't find out what brand it was to get the insurance to replace it.
Thanks for the great tips. I could use some of these as we do get freezing temps at times. I think I've seen that video with the giant stove haha. Yeah it's too much. I love soda. Those bottles are helpful for so many things.
haha yeah one of those stove videos lol
Need to live on Vancouver Island or a similar climate though, that's sort of important!
definitely!
Good sensible ideas
I started my greenhouse the same week as when you made your new one in 2014 god damn 6 years this March god that’s gone too quick haha I stayed heating mine then and haven’t luckily had any problems , Altho the tutorial I followed was one you made in 2013/14 I think 😂😂
Thank you for the info !!
Lovely, thanks
Great info!!
Thanks for this GREAT video!
how can i prevent moisture from building up on the heater?
I’m going to experiment with a fish tank heater. Make a large heat sink. Seal it in a tub of water or something.
good idea!
I have used this method for the last 2 years in 55g drums although not my primary source (electric heater) it’s my most efficient method. Along with others depending on the severity of cold. I left another comment with more details before reading this on this video.
Such a fantastic tips Brad, thank you so much for sharing XXXX
+Desert Plants of Avalon Thanks!
I think at some point we need an update video on your new puppy 🐶 lol
did one just for you on my other channel today. you can find the channel in my reconmended channels on my main page here
make and update video on the Ecuador unusual orchid order!
noted!
Would glass bottles hold the heat for longer?
maybe! good question!

totally agree, great idea
add alfalfa pellets to your mulch and that will super heat the mulch. scatter the pellets between each layer of mulch. alfalfa will also super heat a compost pile when used in the nitrogen layer
That thermostat is good, best is little candles well protected.... Cheers mate.
Free heat would be making a compost pile in the greenhouse... Compost produces heat
2 degrees? Not 32 for freezing??
Depends on which scale…
why not just buy a small oil heater with a thermostat
I use larger candles, pint jar size and turn a clay pot upside down over the candle, put small spacers under the clay pot so air can flow upward as the heat rises from the heated clay pot. if the candle will not stay lit make the hole in the bottom of the pot larger to allow more airflow. fill a clay pot with small gravel or rocks or sand and place it in front of the ceramic heater, the pot heats up and gives off more heat. you can also use glass jars or gallon tin cans, or metal pots from the kitchen filled with water in front of the heater. use water containers that will fit in your microwave and reheat the same water each night in the microwave. my ceramic heaters are on timers and come on and go off at designated times. put your seedling heat mats in a seedling tray and fill with sand or pea gravel to obtain more heat.
This will NOT work
