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

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.

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.

yes it is 
lets heatbomb them jars !

now, you say that it barely increases your watertemp, in the original bomb i used a 50watt heater and a styrofoam cooler.
the idea is to provide small skale incubation which happenes very well within small space, in this case a max of 9 jars. as i switched it on and left the lid of the cooler shut for 24 h, it went from originally 18C roomtemp to 25 and i got it to stay steady at around 27.
its all about the tweaking, maybe you should try to get anyother aquarium heater to try it out.
and i point it out again, for all the nay sayers, this is for "small scale" - want something bigger - go for them titties

this shouldnt really be the case as that would indicate temps exceeding 30-35C, try lowering the "max heat" setting - im sure itll also increase your heaters lifetime.

my heatbomb lives in its cooler and runs at 30 degrees on its dial. this 30 degrees coencides with 29-30 degrees in real live says my thermometer as long as i have a blanket over the cooler.
basically it comes down to aquarious heats arn't really heaters they are stayers. they are meant to keep the temperature up at a temp not heat it up. so its all comes down to unsulation. you could in theory have a big incubator with a pinner heat bomb is it was exteamly well insulated.

Went out and purchased an Igloo 54 (54 qt capacity):

I placed the eight qt jars (seven WBS and one LC) along with the heatbomb into the Igloo. Closed the lid on the electric cord. It didn't pinch too badly at all.
Now I'm up to 79.5F and rising.
I look at it this way; if it goes no higher than 80F, that's fine. I can always turn the aquarium heater down.
Heck. I think I'm going to use this container for my entire grow.
* The internal Igloo footprint is fairly large, about 20"x11". The available headspace is roughly 11.5" or so. So if I use a 3" casing with 0.5" of verm above and below that'll leave me with roughly 7.5" of mushroom headspace.
* This thing is insulated out the wazoo (obviously, it's a cooler) so a single wimpy 10 gal aquarium heater in a heatbomb can heat the whole thing. When it gets warmer and I need to switch to pinning temps I can easily rig up slots in the cover to insert icepacks. Velcro maybe? I'll have a lot of options.
* There is a water drainage port toward the bottom which would allow me to (a) run cables more "professionally", (b) do some active cooling/heating or (c) run a soaker cable through the casing to add moisture mid-grow or even to perform a "dunk" without moving a darned thing.
* Completely inconspicuous. Picnic coolers are about as common as Volvos in these parts.

I don't know. This little 16oz bottle seems to be putting the temps right on the money. I'm at 80.8F now. Judging by the heat increase slowdown, my gut tells me it'll level off around 81.5F or so.
But I'll keep that in mind if the 16oz doesn't cut the mustard on a future grow in a larger area.

Right this second it's 79F in my room but for the last week it's been 69-71F and it has sucked. I knocked up eight jars six days ago and my jars show nothing.
I'm worried that the moisture in my jars might be kaput but here's how I did it. Maybe someone else can tell me if I screwed the pooch.
I boiled a large pot of water. Once it reached a rolling boil I removed the pot from the heat and dumped in 5 lbs of WBS. Strained off all the sunflower seeds. Let sit for roughly 22 hours if memory serves. Placed half the seed into a colander and let it sit for about 15 minutes to drain. Gave it a few shakes. Still quite moist but not dripping. Very few of the kernels had ruptured.
Prepared the jars themselves. They are 1 qt wide-mouth Bell jars. The lids each have two 5/32" holes drilled in with a piece of micropore tape over each. Again, these are fairly small holes.
Spooned the WBS into four jars about 60% full and PC'd at 15 PSI for 60 minutes. Spooned more WBS into three more jars around 80% full (I was being cautious on the first four jars, worried about expansion) and PC'd at 15 PSI for 60 minutes.
Once removed from the PC, all seven jars appeared to be puddle-free but the seeds sticking against the sides had a "water halo" around them. This led me to believe I'd nailed the moisture perfect.
Let cool overnight and knocked up the next day. I only injected spores into one of the two holes in the cover and that inoculation point was covered with a second piece of micropore. So now one hole has two pieces of tape while the other has just one.
I did shake the syringe hard before knocking up. Each jar got 1cc/ml of spore solution with the exception of one jar which got 3ml (on purpose).
Covered all jars with USPS tyvek, labeled them and secured the tyvek with an elastic.
Shook all jars extremely well to both distribute spores and to break up the small clumps. To be honest I've given them a shake about every other day out of impatience, just to see something.
These jars have been sitting in a CLOSED file-sized Sterilite container so there has been very little wicking of moisture from the ambient air. Unfortunately the temps have stayed around 70-74F all week.
So ...what do you think? After a day of soaking and the moisture content like I describe, and the conditions for the last week with no show of myc, would you suspect I have a moisture issue?
I could take a pic but I don't think it'll do any good. They just look like seeds.

nah i think you are fine. 6 days is well within the limits especially since you were running such a low temp in the room. i bet you a print that 24 hours at over 80 you will see growth.
