25 years ago I set up a closet in my basement with shelves and lights, a small fan up high blowing down, and a small ceramic heater on the floor. I can get over twenty flats in at one time and I put heat loving crops up high where it's warmer. The heater hardly runs since the lights put out a lot of heat. Once the plants have been up a couple days, I move them up to the sun room where I have five shelf units with lights. Then when it warms up enough they go up to my two 20/48 bedding plant houses. Thanks for posting, love your content. I'm a 29 year veg grower in Indiana with 1,000 tomato plants in high tunnels and seven acres of sweetcorn and veg.
Pretty awesome idea.. I still haven't figured out growing seedlings..My seedlings just don't grow and look poor. Looking forward to the workshop next week!!
I’m constantly trying to improve my seed germination greenhouse. I don’t have a lot of space to put a real greenhouse so I have to improvise. JM, you are one of my favorite growers to watch and learn from. I am also in Indiana, zone 6A. Thank you?
I'm confused.. if the thermostat is separate from the power cable to the heating wire how does it control temp? I can see it letting us know what temp?we are at but not controlling... ? Maybe it's not supposed to control?
The heating cable you show has a probe already, so how do you attach the separate temperature probe to the heating cable? I've been looking at both products online and trying to figure out where they attach. Love the idea, just need to figure out how to put it together... Thanks
The probe is just attached to a device that controls the electricity before it gets to the heating cable. it would be similar to how you would do a homemade chicken incubator with a light bulb. I guess you would just make sure the heating cable probe is set very high so it is always triggered whenever the real probe is triggered.
Great video! I replicated this set-up, BUT the heating cable (gutter heater) I'm using doesn't provide enough heat (40 Watt, 10m length, supposed to reach 40°C). Can anyone recommend a brand and/or specifications for a decent heating cable? Im in Europe, Belgium. Thermostat was showing temperatures of just 10 °C early morning. When I plug it in without thermostat, it also barely heats up. Tried out bigger cable (90 watt, 20m) same brand, but result seems to be the same.
No real need for plans for this! I just made it to fit my trays nicely and I made sure there was enough room for sand above the wire and foam! Good luck if you make one! 💚
Salutations à tout à le monde ! Petites questions : - ces tables chauffantes ne sont impératives que si on est en serre froide non ? Si on fait des semis à l’intérieur d’une maison (avec éclairage DEL) il nous les faut aussi ? - Au Québec vous semblez avoir des bon website pour vous fournir en matériel. Y a t-il de l’equivalent en France ? - Savez vous où je pourrais trouver les températures préconisées pour le sol des semis (selon les variétés) Merci 🙏🙏
