introducing the 'heatbomb' 7

hey shroomerites!
as ive recently had to construct a new inc and disliked a tit (since i simply dont need such a huge thing) i came about this nice idea for small scale incubator heating and though of sharing it with the shroomerites!
introducing the heatbomb:

the heatbomb itself is a completely maintenance free heating system, designed for small sized incubators - THE choice for ppl who do not want to worry about evaporation of water or possible contams breeding in the wet air inside the incubator if the used to have a fishtank heater in a open water jar or alike.
materials needed: an aquarium heater a plastic bottle that u can fit ut heater inside silicone gel duct tape some boiled (distilled/germ free) water
how to assemble the heatbomb: 1.) its up to u to find one heater and a plastic bottle that takes the heater inside without leaving too much space on the sides.
2.) once u got ur bottle and heater ready, wash off all the paper lables that might stick on it and give the inside of the bottle a nice hot water wash since it cant be bad to kill all the germs u may be able to kill.
3.) next, boil some water or take ur distilled water and fill the bottle up to the brim.
4.) now, insert ur heater, it will cause the water inside the bottle to splash over since the mass of the heater forces it to, but its allright since that way u dont leave any possible air inside (i, sloppily still did though )
5.) next, wipe the area around the top of the bottle dry and start to apply silicone gel to where the heater enters the bottle, just apply a lot of it, u want to have a good and waterproof seal.
6.) let this sit for a day to allow it to dry fully (silicone takes some time)
7.) now, apply duct tape over the top of the bottle and the heater, covering the whole silicone seal as an extra 'anti leakage' precaution.
8.) wipe down the heatbomb with rubbing alcohol to sterilize it.
well, taht's it, there u got ut very own heatbomb, ready to use 
the jars pictured were entirely incubated in the heatbombed incubator and reached full colonisation within 10 days, its straight rye.
sure, it can never ever beat a proper TiT but for ppl who just need small scale spawn its THE choice since it works like a charm and heats up ur inc pretty fast 
here some more pics for u, just for kicks:
typical heatbomb setup:

i hope some of u find this handy, i sure love it! and btw, im proud to contribute my first 'tek'  peace ohm

Did you happen to notice colonization occuring closer to the heat source or was it even? The idea behind TiT is surround your jars with a heat source from an even angle. Ive also heard disclaimers about putting a heat source directly in with your jars such as a space heater. In your experience how was the colonization?

Damn what a great idea. Sobe bottle + water + aquarium heater + incubator = lots of mycs

i indeed get faster colonisation in jars closer to the bomb. i am happy with it, it serves its purpose well.

hey!
first of all, im glad that some ppl are actually using this tek, furthermore, archiving good results using it ! 
concering all the chatter going on about a glass or a pvc bottle, ill quote anno's statement he gave on that topic.
Quote:
Well...
Glass has a thermal conductivity of ~ 1 W / m K.
PET( Polyethylene terephthalate, the material the plactic bottles here are made of) has a thermal conductivity of ~ 0.3 W / m K.
Taking into account that the wall of a glass bottle is much thicker, the end heating result will be roughly the same.
this tek was also designed to be run from PVC bottles and it works like a charm, NO NEED for glass bottles to make that clear. all this glas chatter may have distracted some ppl from actually building themself a heatbomb, believe me, i use the same pvc bottle i used when i initially constructed it, and it works supremely well! peace ohm

Do you have to keep space between the heat bomb and the jars so they don't dry out? or can you pack them all around it?

I have a TIT, without decent lids so humid is coming up from watertub and RH in incubation tub is rather high with waterdrops on "ceiling".
What I like about your method is that it is DRY.
BUT the advantage of a TIT is there is more heating volume, coming from all sides.
So me wanting a dry TIT me gonna watch for some tubs with decent LIDS on it!
For a small incubation setup your heatbomb must be very cool, only need one tub also. If one puts it in a isolated coolbox one should have a great incubator.

Too bad that idea doesnt work as well as everyone thinks it would. The jars in the middle get hot and the jars by the edge of the tub get cold. edit: now that i read the tek again it is noted that its only best for a small space, keyword, small. It does leave the incubator dry though. as said, this idea simply doesnt compare to a TiT, not really even close. Even if one wraps the hell out of the whole tub in blankets you will not get an even heat. Stick with the TiT, there's a reason it's called the best.

Thats why I said its maybe in a smaller well isolated environment when more even temperature can establish. But, it is like a poor mans tit.. :P (you only buy one tub)

well thats what it was written for, small, low scale incubation, believe me its the bomb!
just take a look at the provided pics, thats a small space and low scale incubator, all jars, regardless of being in the middle of the edge were done within a couple of days.
<3 heatbomb.

My cat made something similar, only he used a big glass jar which was formerly a candy dish. It was about 8 inches high, and had a diameter of about 6 inches It worked very well!

*bump*
the heatbomb needs to be spread among newbies who want to do small scale incubation since this is what it was designed for. peace ohm

thx a lot man This is gonna work great for me. I'm gonna use my pmp as an inc until they're colonized.

i had one of those goin last year, but didnt get the silicone, and so it leaked humidity EVERYWHERE! i was too lazy.

thats why i made up the heatbomb, the leakage was a unbearable problem for me aswell. the heatbomb itself is completely waterproof self contained system. peace ohm

considering the heat conductivity, doesent it just mean that one will war up slower then the other? wont they ultimatly reach the same max temp after enuff time has passed?
whats the wattage of that heater?
does your heater have a notice in the manual that says it needs to stay verticle? mine does but im wondering since ive seen no1 else gie a crap about that...
comparted to a TIT, is it realy that different? seems to me like most of the effect comes from heating the air inside the container as opposed to direct radiation...
oh yeah hows about using hot glue instead of silicone?
