Got my heated bed all finished then realized that the heat cable i put in would not work as it was for water pipes and it will not come on until its near freezing,back to the drawing board.the good news is that its about 10 degrees in there so that ok,plants are thriving
Gday Jason, At the start of this video you mentioned the previous weeks video about "greenhouse benches". I've searched but cant find that video. This video seems to be your first. Have you remove some early videos? I'm interested in how you build your standard benches. Thanks Greg
Thanks - I did end up removing that video based on some quality problems I couldn't fix. I may have to do a quick one on greenhouse benches again, now that I'm a little better at making videos.
I'm curious if the foam at the bottom, lasts with the heat and humidity. I know it's designed to handle the heat, but it might encounter more humidity than it was originally designed for, which might reduce it's life span.
Hi Richard. It held up very well, and I use it a lot in the early spring when I'm doing seed germination. I haven't been tracking electricity for the bench specifically, but I'd be surprised if it was very costly. The soil volume isn't much, and it's well insulated. The one adjustment I've made since then is I replaced the sand I was using with my potting soil (mainly composted bark). The sand was drying out too quickly - and dry sand doesn't do a very good job of transmitting the heat to the seedling trays.
I'm building a propagation bench with a heating cable basically the same as your video, but what about drainage? My bench base is plywood, then lined with black plastic, then the reflective insulation, sand, heating cable and more sand. Thinking that even with misting the water needs somewhere to go?
I had that in mind too when I first put the bench together. My plan was to use a spade bit on my drill through one or more of the corners, and install a downward sloping piece of PVC pipe. For me, it turned out to be unnecessary... the sand conducts the heat better when it's moist, and I found that once the greenhouse began to warm up (and with the cable working), evaporation was outpacing my watering. I actually had to lift the seedling trays to water underneath because the sand was drying out too fast. I guess it would depend a lot on your weather, and how much you're watering... but it wouldn't be much trouble for me to install them if the need arises.
Thanks. I did an update video to figure out the electricity - it turned out around .47 CAD for a day or approx $15 per month. Might vary a bit with outdoor temperature and local electricity costs, but that's my estimate.
hii can you tell me how does it work when the winter is in the deepest bitter night ? and how much does it cost to run for a month in the deepest winter ? just want to get a rough idea before jumping into it. is the bathroom floor heating cable can be used in this case ? there is another type of twin cable with some sort of carbon plastic in between that will adjust how much heat to put out at each spot.... that's also for indoor use. is it ok to use in this case ? thanks andrew
Does using a lighter-weight media still work to hold the heat? I detest sand, it is so heavy to work with and I don't want to break the bench or my back! I cut in a lot of perlite, to the mix itself, my cuttings seem to appreciate the airiness. I am not sure if that "air" will just let all the heat escape though.
I'm replacing the sand with composted bark this year... the sand seemed like a good idea at the time, but it dries out quickly in practice. I had to stay right on top of watering as dry sand doesn't conduct heat too well. The heating cable is designed for in-soil use, so I'm hoping my new approach works better.
I've thoroughly enjoyed your video and will build the table as you suggested. It was exactly what I was looking for, thank you!
Nice job. Have seen gardeners propagate cuttings in just sand, this would be so cool for that. Didn't even know they made soil heat tape!
Going to start building one tomorrow
Very nice build, another hubby build to add to spring list 😁
Nice video! Thank You.03.07.2024
Great info- thanks!

This heating cable shuts off at 131deg F. How is that not killing your plants? Do you have that plugged into a seperate t-stat sensor outlet?

hii,
did you have update video ? how it is like during winter.
Great video,just wondering if you cut the cable and put a plug on or is the plug on already
Curious to what brand of soil heating that was and how much approximately- thanks!
Ps great video!
The brand was Hydrofarm (from Amazon) and the cable was around $60 (CAD)
I'm curious if the foam at the bottom, lasts with the heat and humidity. I know it's designed to handle the heat, but it might encounter more humidity than it was originally designed for, which might reduce it's life span.
Hi Walter. I Had a chance to disassemble it recently, and the foam held up fine.
Great video! I'm trying to find the heating soil cable, can you provide the link for that please?
Thanks Edda. I have it on my "Propagaion" shopping list at Amazon: www.amazon.com/shop/fraservalleyrosefarm?listId=2YK06EGYXJ0ML
@@FraserValleyRoseFarm thank you very much!
Is that 4’x8’ table and what length is the cable?
Can you please tell me what misting or watering system you are using with this heated bench?
Where do you purchase the heating cables?
Amazon
Great video! Its been nearly two years since this video was posted. How has your new bench held up? Could you share what it costs monthly?

Fraser Valley Rose Farm thanks, really good info,
Hey would you know how effective dry sand would be? As I am going to have this in my house and dont really want to have mold issues
thanks for the video, but u didnt include electrcity costs , i think they are above 50 USB per month..

Good video where did you buy your heated cable

Perlite is an insulator, so I don't think it would work to well.
Hi there,
Stupid question. When you said -5 degree outside did you mean -5 Celsius or -5 Fahrenheit?
Thanks
Not a stupid question! Big difference... in this case, it was Celsius
@@FraserValleyRoseFarm Thanks!!
