Ok, Nan told me I needed constant temps. So in my closet, I made a little box with a shelf and the walls, and the ground. On the side where you open the door, I nailed a black cotton shirt to keep heat in and light out. Then I made a diagonal board going top left to bottom right for space issues. UNDER the board are my jars. ONTOP of the board, is a 60 watt lamp with a 60 watt bulb, resting on this thick plywood slab. I covered the walls and the top with saranwrap, to keep the heat that rises up, down. Then I have a towel on the bottom edge crack of the door when it's closed, to keep anything excess in.

The bottom is a rug, that's my main concern. Is this dangerous? The area is about 2' by 1' by 1'.. not very big. 60 watt bulb resting on a slab of thick plywood, with the jars under it.

Should I only keep the light on for an hour or two every 6 hours? I can't afford a timer :( Hmmmm.... What if I put the bulb in a bowl of water, with the diameter of the bowl small enough to keep the electric part of the bulb out of the water. Safer? Extra humidity help at all? Muchos gracias seniors.

I would not set the bulb on anything flammable like wood, cardboard, plastic, cloth, carpet or the like. Use a ceramic tile, brick, sheet metal, something that will not catch fire.

Don't submerge bulbs in water, it is a nasty shock hazard.

You can make a heat sink/protector out of coffee cans. Mount socket for light bulb in a small coffee can. Run the wires out of the bottom of the can. Using the can as a metal lamp shade, add a new and larger can/shade around the small can.

You now have a lightbulb in a can, in a can.
Just duct/electrical tape, wire nut, protect your wires from cuts and shorts.

As long as nothing gets IN the can, things touching the can will get warm but not hot. You can run one of those heater bulbs on a timer.

Just check out the cost- timer $10 (home depot/lowes/etc), heat bulb about $10.

I don't know if this helps you- It worked for me once.

I incubated my jars with a heating pad on top of the box set to low. This worked well. I want to use the heating pad as an a heat source for the fruiting as well. I have 2 sterilite containers sitting on top of each other with the heating pad in the middle. Will this be enough heat? Should I perhaps turn it to medium rather than low?


By the way, I had to leave a flat cake for about 5 days. When I left there was nothing on it but now there are small shrooms popping out of the sides. Since I haven't tended to them for a while I'm wondering if there is anything I should do other than start the normal fanning and so on?

By Cragith Kilbonith (Kilborn) on Sunday, November 25, 2001 - 10:14 pm:

should be fine, keep it on low. are the jars in the 'maids with the heating pad in middle or ball box with the heating pad with another box stacked ontop?

Perhaps you might be able to buy a thermometer and then you could experiment with the temp setting to get it where you want it to be. I got an electronic one at walmart for about $15 that tells the humidity and the temp... just a suggestion...

By Patrick (Valence) on Monday, November 26, 2001 - 05:56 am:

Remember that keeping normal, short term use heating pads on all the time with things on top of them is a possible fire hazard. There was a long discussion in here about that but I can't find it. Find something to separate the two chambers. Some kind of riser on all the corners will do. Doesn't have to be high, just not compressing the pad. As far as using a heating a pad for the chamber themselves. It doesn't give even heat for the whole chamber. One side will be cold and one side will be hot. Would work better in a small enclosed space or wrapped in a blanket. As far as the temp. You can get a strip thermometers for fish tanks for a dollar. This would work. Better to have one side colder than normal than to have one side to hot.

By Herman Manderchuck (Youenjoymyself) on Monday, November 26, 2001 - 06:47 am:

How cold does your place get?? I've never used anything to amplify heat during fruiting and everything always turns out just fine....Be careful with those heating pads!! I've heard horror stories!!!Low temps can only slow growth, heat can kill....

i just birhted my pf cakes 2 days ago and i am getting paranoid. i have 6 pf cakes in a 10 gal. aquarium with moist perlite at the bottom. I have a heating pad under the tank to keep it warm.(reason for doing this is because we keep the house cold about 70- 75 deg. i mist the sides of the tank once a day. and fan the tand once a day. i have a 50 watt. reptile light in there that is supposed to be almost like natural light. i know i seem paranoid but this is my first batch. i would feel a lot better if i could have some reasurrance. thanks a lot for all the help

much love

everything sounds ok,
but i hope you put a spacer of some sort between the heating pad and the terrarium.
it's a fire hazard if you let it weigh down onto the pad.
or put the pad on top of it.
be watchful of the perlite moisture when using heat, it dries out much quicker.

By serialkiller1 (Serialkiller1) on Wednesday, November 14, 2001 - 05:51 pm:

i put a towel in between the tank and the pad

By Nan (Nanook) on Wednesday, November 14, 2001 - 06:04 pm:

Unless you are using a pet store type under tank heater (UTH) for reptiles, you have a potential problem on your hands. Regular heating pads are not rated for this service and creates a fire hazard.

If you can figure some means to take the weight off the pad you will be OK. What you want is some spacers under the edges of the tank that will lift it up high enough that the pad moves around freely. This will also go far to help regulate the temperature.

And Quote is right about Perlite drying up when using bottom heat. Stick a finger in there on occasion and make sure it is staying nice and moist. Add some H202 & H2O when required to keep it hydrated.

By serialkiller1 (Serialkiller1) on Wednesday, November 14, 2001 - 09:00 pm:

how far above the heating pad? and what type of spacers? like 1-1 1/2 inch pcv spacers. for plumbing. i thought the towel would be enough. one more question. how much light should i give ive been doing 1 to 1.5 hours on and then 4-5 hours off.thanks for the help guys.

By Nan (Nanook) on Wednesday, November 14, 2001 - 09:30 pm:

How thick is your pad? Lift up the tank one pad thickness, just enough that there is no pressure on the pad. The spacers can be anything, stacked disks of cardboard even. Just make sure you provide enough support.

The Light is no problem.

Sterilized and innoculated my jars! I used 9 1/2 pint canning jars with a cooked brown rice substrate. Though I have both Mazateca and PFC I dont like putting all my eggs in one basket so I only used the PFC. I used nine jars so I could give one jar 2 cc's of liquid to see if this speeds up colonazation or not. Im keeping a journal of my little project and will keep you guys updated. I want to say thanks to everyone here. You all have helped me to finally get this going. Thanks guys and gals.

how are you incubating them ?

By The Silly Scybe Scribe (Toadstool_God) on Wednesday, January 02, 2002 - 02:05 pm:

Small nightstand lookin thing with a heating pad underneath keeping it about 80f. I also have a small light in there because Im planning on growing them invitro.

be careful---don't put any weight on a regular heating pad---
instead, use a spacer of some sort to lift the container/terrarium at least an inch or so above the pad.

Ok, I've decided I'm buying a heating pad to put under my filing cabinet - incubator. Now what do I need to know before buying? I figure the size would be the same as the base of the filing cabinet, but how many wats and stuff like that?

Posted by: DirtyWOP Jan 01 03, 11:56 PM GMT
Heating pads are okay. I have one. But if you're already gonna go buy a heating pad, maybe you should think about buying a fish tank heater to put in a glass gallon jar. They have thermostats and keeps the humidity high to keep your jars from drying. I haven't seen any incubator that works any better.....

The one I have doesn't even get that warm on high. I guess it depends what kind it is. One for reptiles is probably best....

Posted by: raze Jan 02 03, 10:32 AM GMT
I have two of those fish tank heaters, and I hate them. They dont do shit. The air near the water jar is warm, but everywhere else is just as cold.

Posted by: Nanook Jan 02 03, 11:35 AM GMT
Regular heating pads are not rated to have things set on top of them. Try and Under Tank Heater from a pet store that has a reptile dept.

No clash with Nan.

The pads I use are inserted into the 2 or 3 inch space between the bottom drawer & the bottom of the filling cabinet. The filing cabinet does not set on top the pad. I also placed a peice of fireproof material under the pad.

Whatever you do. Be safe. You do not want to create a FIRE HAZARD.

I also wired a reostat into the pads plug in line. That way, I could control the pads heat output - better.

Thats what I was planning on doing, sticking a reptile heating pad under my filing cabinet. There's 2-3" there for it.

Posted by: Mycota Jan 02 03, 05:55 PM GMT
I don't know how high or how many drawers yours has. Mine is has 5 & is about 6 feet high. The bottom gets warmer than the top (duuuuh). I put a themometer on each level, cranked it up & adjusted the temp, to a happy medium - on all levels.

If the drawer bottoms are not perforated (at all), you can drill holes in them, to allow for better heat transfer. Simply fill a drawer (tight) with empty jars. Then take a felt tip pen (taped to something skinny, so it will reach between the jars (in place) & mark spots where jars don't set.

Then - drill 1/4 inch holes there, on each level. That helps even the heat out - on all levels. I love mine. The sumbitch works perfect & is easy to get in & out of, anytime you want to use them.

Mines 2 levels, and has holes in between. So I'm thinking it should heat fairly well.

Posted by: sinsimilla69 Jan 03 03, 02:24 AM GMT
got mine at the pet store brand is zoo-med undertank
reptile heater they come in all different sizes some of the larger ones have rheostats to regulate heat

It should. I had to tinker with mine. It's 6 ft high & wide & 2 ft deep, so even heat distrabution was an issue I had to resolve. But once I had it figured. The puppy works like a charm. There is only about a 2 or 3 degree differance between the top & bottom. Mycota
