Use a cheap heating pad found at most drug stores.

Ok, what Im doing is taking a heat lamp and using a 60 watt black light. It heats my jars to around 80 degrees. A heat pad might work better though. Im just using what I have, I dont know if the light is a bad thing or a good thing, but I have a pint canning jar that is almost fully colonized after like 3 weeks. Im such a newbie at this though.

i have been trying and trying to get my stupid heating pad to keep my drawer at a constant 80 or 85... but even on the lowest setting, it makes the whole thing like mid-90s. i gave up for fear of damaging the mycelium, but their movement has kinda slowed down... i think they're too cold. i know i didn't dry them out too much because i'm actually still having some moisture problems with a few jars. what should i do?

N8,

what I did was put my jars in a Coleman cooler. I put the heating pad on top of the cooler with a towel covering it. I left the cooler open about an inch or so. i found that playing with size of this venting area I could create the correct temp with only minor variations of 3-4 degrees based upon time of day, household heat use, etc.

If you use a fish tank heater, get a fully submersible one. They are most definitely worth the money since they can be used in shallow water, unlike the ones that have to be vertical.
Also, get a low wattage, probably 50. Otherwise, the temperature will fluctuate more, and you'll likely have a problem maintaining a good colonizing temp.

I've got a solution thats almost free.. and I've been using it with stable success..
Here goes:

I grabbed a cardboard box, not too big, but big enough to hold about 24 jars if i stuffed it full, half of the space is used for the heat source though, so my box only holds about 12. I flipped it upside down, cut off the flaps and then cut down the corners of one end.. to make a "door".
So at this point you should have a box, with no "floor" and a side that flips up. I cut a whole in the "door" ad taped a few layers of plastic wrap on the INSIDE of the box to make a window, so I could monitor the tempature (You might want to keep the piece you cut out for the window, it rises the temp about 3 degrees if you stick it back on). Then I cut a "X" in one side of the box, so I could stick a light bulb in there.

Now that you have your shell, stick a small thermometer in there (I use a paper thin aquarium one with an adhesive backing), and punch a 15watt lightbulb through the "X" in the side. Site the whole thing on a blanket, and flip the blanket on over the incubator for added insulation. If you want to be sure you don't catch anything on fire, make sure the bulb isn't touching the cardboard, and place a peice of foil under the bulb on the blanket.

Ironically, I came up with this idea when I was stoned, and started building it. Once I sobered up, I looked over my plans and decided to give it a go. Turns out it works great. It can keep the tempatures up to 20+ degrees above ambient! It takes some figiting, and a little getting used to, but now I only check it when I wake up, and when i go to bed.. and its always between 83 and 86. I keep the door open though, otherwise it raises up too high..

I hope that was clear enough to help you or anyone else out. All in all, the whole thing cost me... absolutely nothing...

wow.. those are some really good ideas. i'm surprised there isn't more info on heating in any of the beginner grow guides.

I use a lamp fixture and a forty watt bulb wired to a thermostate. Both are built in side a large metal can and the can is attached to the bottom of an insulated box. It is very reliable and can be set to any temp. I may post the plans soon.

I put the jars back in box they came in, tossed in the temp probe from one of those indoor/outdoor digi thermometers, and placed the box on top of my computer case, So far so good.

Temp stays between 79F and 91F, but averages about 85 or so.

mycomountain, please post those when you can, we will all surely be interested. After reading many posts here today, I don't think that most people understand the importance of temprature. Take it easy.

Alien's idea should work well, it is esentially the same principle as ShroomGod uses. This is probably the best method to keep a steady, and even temperature, and it actually isn't that expensive (most expensive thing is a good aquarium heater which is about $25).

Heat pads suck! :mad:

I have to use one right now, and it sucks so bad! :rolleyes:

alien, i like your idea and i think i'll try to build an incubator like that.. just a few questions.. do you keep it airtight, or do you even have the lid of the large tub closed at all? how many jars will this setup handle? is the inner tub supposed to be floating, or does it rest right on the heater? is the heater silent running? thanks for the idea, i really do like it a lot..

n8, I've got anpther suggestion. I think its much easier than the rest, but I dont know what is the availabiltiy of this in the states. Ok go to your local pet store, and ask for an iguana heater. Ask for the kind that comes like a long string. You can use this as a heater in your incuabtor. Simply make a hole on the side, put the heating string through and seal with duct tape. You can adjust the temp by adjusting the length of the string isinde te incubator. It works like a charm for me!

Later,
tweedy.

Where'd you find a thermostat that can handle 110v? A furnace thermostat is something like 24vdc.
