Actually, it's pretty easy if you understand what you're looking for and what's available. Like here he needs warmth, a way to keep humidity, a growing medium and he built everything around those perimeters. But I agree, he's a creative fellow. I think he could even have gone more DIY with more features, but this is a simple solution for everyone. Awesome. Wish I had the space to do all that stuff. Very inspiring.

Great idea, never thought about such implementation.

Such a great channel, so much useful info and fun to watch! I got a Stewart variable recently and after lining with sand as per instruction and putting potting soil straight in, so no trays used, I got great temps. Room ambient 12c soil 28c. I used the bubble wrap it came with and and old dressing gown to wrap it up and insulate. Love your DIY version, hope you have a fun and successful season!

Great idea! I'm just starting out this year but I will definitely keep this in mind for future expansion of my growing ambitions 😁 Thanks for sharing!

great tip i was not aware of the insulator factor..this will definately be a game changer , as i had some failures in germination last year and had to keep replanting. thx

This is just the video I needed. Thanks Shaun! Thanks for speeding up the video in areas where the information is essential, but there is no requirement to spend 60 seconds when 10 seconds will do. appreciate your sharing.

that's my job in the next couple of days....its going to be interesting!

I need to try this

Yay a heated prop, and we were only just discussing that on discord! I wish I knew this was coming. Luckily I haven’t ordered one yet.

Very good project! I did a similar one a year ago but for one of my snakes. I put the heating cable into the desired position and poured concrete mix above it, so the entire thing became like a heat rock. The rocky material spreads the heat nicely. Your method is superior in this case since there's water involved. Not because of electricity, but because you need air pockets which the gravel will give you.

That is a very creative solution Shaun! I have been "toying" with the idea of picking up some "heat tapes" to use out in the cold room that is attached to the west side of this place I stay at. Here heat tapes appear similar to yours, with primary purposes or preventing water line freeze ups in the winter and to provide open trackways in roof gutters to prevent ice damns from backing water up under roofing materials. May have a go at that as the hardening off process begins in a couple of months. Bit more seed starting later on today. Happy Seeding! Stay Spicy! -Bob...

I did the same last year using a growbag tray was a bit shallow. Did have very good germination rate.

Roll that beautiful watering footage!

Nice build! I think the dome can be as easy and cheap as joining 5 pieces of plexiglass together, drill a few holes and place a slider on there 👌

This is just the video I needed. Thanks Shaun! One of the places I hit a snag last year was my plan for heated propagation. I got some mats from Amazon, but I couldn't get over my worries of having a fire caused by the mats. I read some reviews that warned of that, and it scared me. This setup you do hear will fit perfectly in the space I build for my seed starting. The area I'm doing it is in my basement, near enough to the furnace, and hot water tank that it's nice and warm to begin with. I have a restaurant supply store right near me where I can get the plastic trays at a good price.

The heating mats from Amazon work fine, I have always used them for chili, eggplants and tomato propagation without an issue. If you are worried about fire because you leave that area unattended the system described in this video is not gonna be any safer. Actually worse because the heating cable is in wet sand, and if anything happened to that cable or had it been defective you have a fire hazard. I am not criticizing this system, I am just saying that one is not better than the other in terms of safety

Fantastic! Thank you very much for this! Also, greetings from SA :) .

Great video once again Shaun! I was going to build a propagation bed similar to this a few months back but the cable was out of stock so ended up getting a extra large heat mat.

Hey Ryan. You can put your tray on top of the fridge. That is normally quite warm. Something else I've done with success in the past is put the tray on top of a satellite box/TV tuner/set top box. They also have a bit of warmth to them.

As for the cable problem… I have, before now cut the cable clamp along its length, put the cable through the hole an then fitted the clamp into the hole. A little glue or masking tape holds the lot together.

Hi Shaun. Thanks for sharing this really useful set up. I'm going to build it but have a question. If you put seedling trays with domes on top your heated soil, do you need to know/regulate what the temperature is inside each dome? Or do you just assume that if the soil is heated to 30 celcius, the air within the heated dome/s must be around the same temperature? or hotter? Could it get too hot within the domes for example? Thanks

Essentially I monitor the temperature in one of the propagation trays, and control the whole thing based on that one's temperature. It will keep them all within a margin of error.

Wanted to make sure I understood the "bed" materials below the propagators - believe you said sand mixed with vermiculite, but the texture didn't look as "sandy" as I expected. Please confirm what type of sand you used. Thank you for sharing these types of hacks to keep our hobby affordable and successful!!!

Hello, thanks for the video. Some questions...is it possible to substitute 100% vermiculite or perlite for the sand element? My alu/polycarbonate propagator is 1m x 60cm so you can imagine how heavy it was with a thick layer of sand/perlite + water + seed trays. My other question is re. fire risk. When I dismantled the current layers, the cable had actually melted grooves in the thick plastic sheet and the polystyrene in the bottom. This was despite using a thermostat set to 25°C. Not good! I'm rebuilding the layers but want to reduce the chances of an accident. Any thoughts, please?

@ChilliChump

This is one reason I recommended in the video to use vacuum seal bags or even sousvide bags....they can handle hotter temperatures. The only other way to deal with it is to create a barrier between the heat cord and the plastic. Yes you can use pure vermiculate if you prefer.

thanks for this. However, without a dome of some kind over your propagator tray, you've built yourself a potting shed heater, and it'll be costly to run, given the difference between ambient of 17C and the heat in the vermiculite base of 34C. Did you eventually provide it with some sort of cover?

It helps transfer and store the beat better

Hort student here and I am in the research phase of trying to create my own prop bench. A few questions: Why do you vac seal the bottom thing of vermiculite? Now that you have likely had it running a bit - have you checked to see if the bags melted at all? Does your set up stay on at all times or does it turn off once it hits the desired temperature? Why use Vermiculite for the bottom insulation vs. other insulation material (ie. those insulating boards)? Vermiulite can be quite expensive. If you are using it only to help retain moisture in the sand, why not simply add some water to the sand when you are watering the seedlings etc. ? Thanks for sharing your experience.

@ChilliChump

2 жыл бұрын

I vacuum seal the vermiculite because it is there as insulation. The vac seal bags don't melt...they don't reach temperatures that would be a problem. These are the same types of bags that are used for sous vide and reach much higher temperatures when used for that purpose. Yes you can leave out the vermiculite from the sand if you want. But you will be having to water it more frequently. The thermostat will turn the heating off when it reaches the desired temperature.

The sand / vermiculite should be damp for a more even and consistent heat distribution. Keep in mind that the further from the center, the substrate will be cooler.

The bags are the same type you would use for Sous-vide so I doubt they will melt. And yes, there will be heat loss, just make sure you fill the space with as many seed trays as you can. And once they are no longer seeds, and you pot up, you can put those pots in the heated bed too.

You could try to make the tub from polystyrene boards and line it with HDPE pond liner (that is how our brooding/hatching apparatus is built). I went a different path: I got rid of all the years worth of old trash in the heating compartment of the basement, anf the room next to it. put cheap wooden shelves in it and invested in some of these LED growing lights because it is much cheaper to bring light into the house than it is to bring warmth to a shed (we have continental climate). We have a wood pellet firing stove (furnace? no idea, I'm German) so there are almost always 24+°C in the heating cellar. humidity is not a problem, as the stove draws a lot of air to burn the wood. But be dilligent with the watering can! (same reason)
