Problems Using Heatbomb
    #5586841 - 05/03/06 05:35 PM (17 years, 8 months ago)

So I made a standard heatbomb; 16oz soda bottle filled with water, wrapped tape around top of heating element to make the heater fit perfectly into the neck of the bottle, inserted the heater and taped the mouth to seal the whole shebang.

Inserted the heatbomb into a container about the size of a portable file box (12"x11"x8") surrounded by eight 1 pt jars filled with WBS and my remote thermometer sensor.

I'm getting about +0.5F (started at 70.0, now at 70.5F) temp increase. That's IT. Am I doing something seriously wrong or are people over-selling the potential of a heatbomb to raise temps? I mean, the heating element is turned all the way up.

Heck, I just checked the temp of the surface of the bottle and it's at 96F. The remote temperature sensor is about 5" away and if it barely put a dent on the sensor, I doubt it'll impact WBS through thick Bell jars.

I've never used a heatbomb myself but I can't imagine that it would radiate that much heat it's a matter of surface area. Most people use TiT's they are just about the easiest and most efficient way of incubating

maybe the temp on the heater will have top go up. if the theromstat only goes to 105 or so i would think about getting a tub in tub.

I've turned the thing up as far as it can go. Long story short, the temperature control is adjusted by a pin that depresses a contact. I've got the pin so far recessed that it's actually retracted into it's sheath, which makes any further adjustement pointless. It's as high as it can go.

I'm just baffled because I've heard raves about the heatbomb. Now that it's sitting and stabilized I've got a whopping +0.7F for my effort. Why are these things even mentioned?

maybe they just don't work for you. personally i have never used this tek but maybe you need a bigger heating element. personally i would just use the one you have and do a double tub. saves you some money.

Forget your heatbomb. "Heatbomb", that's hilarious.

Go with a tub in tub man.

Cheap, easy, effective, did I say cheap? Did I say effective?

Just remember to put some h2o2 in the water and you're cool.

I stick my heater to a small piece of glass that holds it on the bottom, and boom! done.

Good luck!!

thenewguy05: If we make the assumption that the laws of physics don't go ass-over-teakettle in my room, then it should work just as well for me here as it does in, say, India. And I'm using the same size heater always depicted in the teks.

Besides, if I got a bigger heating element it would just heat up faster. It would still turn off when it hit the top temp and it would still radiate like ****. Remember, the box I've got the heatbomb in is only 12"x11"x8". That's like 0.75 cu/ft. There isn't a single jar in the container that is more than 2" away and the box is clamped shut.

I think the "heatbomb" was one of those blips of the mushroom cultivation radar I really never heard of anyone actually using one due to the overall effectiveness of the TiT

^^^ i agree. haven't seen too many in use but i did get the details when this method first came out. tub in tub seems to be most popular.

im using a heatbomb from what i can see it basicly comes down to traping the heat that radiates from it effectivly. a cantainer with good insulation.

Hmmm. Thanks for the advice, ssjwizard. I'll see if I can wrap the whole shebang in a blanket and see if that helps matters.

I am using a heatbomb too. I have it in a coleman cooler that is probably 2 feet by 1 foot. I can keep the temp in that thing at a constant 84 using the heatbomb. I think it might be a matter of insulation. I tried using it in a large rubbermaid tub and I could only get the temp up to 76, but that is still more of an increase than you are seeing.

On a side note, I think the outside of my heatbomb is getting much warmer than yours. I have it in a glass sobe bottle, but when it is on it is so hot that it nearly burns to touch it.

I have a friend that made a heat bomb, and it kicks ass. He puts it inside a tub and wraps it with a sleeping bag. If you insulate it, it will work.

i use a heatbomb and it keeps a 1'x1' container at a happy 85. constant temp. has really simplified things for me, i just plug it in and go. the size of the container has a large effect on its heating capability.

yeah i had to convert one of my tubs to a FC to increase yields on last grow so i cobbled together a heat bomb. worthless. i did see a tek the other day where a polyurethane bag was used to purported great success because of its conductivity. but i TIT. and by the tie downs because they really cut down on H2O loss and overall surface area in the tub that radiates heat. but 4 me? heat bomb is worthless

I placed my box into a larger box and completely surrounded it (including) bottom with a large blanket. I've gained roughly +2F, now up to 72.9F.

Tomorrow I'll try to find a cheap insulated container. Failing that, I'm just going to grab a nice submersible water heater at the local pet store and go TiT.

Thanks to everyone for the advice and comments.

Woke up this morning and the temps are at 75.2F which is roughly a +5.2F diff. Not so bad. Maybe I'll find an Igloo to use, see how that works.
