Warning! Seedling Mat Temperatures

[hotrodharley]

hey hotrod, could you put a pic of yours up? i'm wondering if all these mats are from the same shop iin china? i do like herb and suds does and put it between a bath towel.

With the towel as I have it now? Or the bare mat? Never mind I reread

I laugh but know it's true.

i know right? it's always in the back of my mind. i have those exploding balls in my bloom room. if they heat up, they explode in a huge bunch of fire powder.

I put mine in a tray which helps lower the hot spots as well
I’m always worrying using those mats
But sometimes ya gotta do what ya gotta do

Yep. I have 5 of these...I run 4 off of one controller without problem and I've never had 'em short from being around water. They're pretty well sealed around the edges and assuming the outer 'shells aren't damaged, don't think they're going to short. Did this on my last run with them. I didn't have a dummy pot (since I was using 3/4 Gallon pots, but did have the sensor sunk down in one of the seed pots as I would normally.

It's -32F here right now. Standard winter. So I bought a heated seedling mat. Literature says it operates from 70-85. Tops of medium drying kind of quick with the tent 72F.

Took my Fluke Infrared and shot the temperatures of everything. Mat 86-92F. Cups 77 halfway up.

And they advise using a dome? FYI. Vivosun 20"X20" model.

Never a dome

I'm using an inexpensive temp controller (PID) to control mine exactly. I also use it to ferment bread doughs and such. Hydrofarm mat.

Same. I used to use mine to warm a little vacuum chamber while making shatter and the mat was too hot on its own. Now it's just nice to have.

I've got a handful of the vivosun mats and a couple of their controllers. Makes sense that they'd run hot down low to me...part of that is getting the sensor placed right. I like to fill a 'dummy pot' and bury the sensor about 3/4ths of the way down into it. I've also put it under the pot, but I think you don't get the temps you want at the top of the soil that way.

I set mine to about 78 and run it for germination and the first week after that.

I stick the probe in a Root Riot cube.

Do you have a thermostat?

Trying to use my Inkbird. But I like the looks of this. Thanks.

This should solve your problems.

And stay warm. You can use the heat mat for your ass too if the clones aren't, lol.

Edit: What Inkbird do you have, because that might be the same thing. This one looks like it should be able to work the same.

Hey we're supposed to be above 0 next week. Heat wave coming.

 

[hotrodharley]

Not a bad. Sitting on one or using it as a heating pad b

I hear ya. I lived in SD for awhile and that place gets cold as fuck with crazy wind. -30 is no fun.

I use mine similarly. I bake too and use them when our house's ambient temp drops down into the mid to low 60's for proofing both standard yeast doughs and fermented (starter based) doughs.

The Vivosun people also sell a thin-long version meant to go around brewing tuns so that you can keep bottom fermenting yeasts warm.
