Impulse sealers

So Im switching over to bags, hastily bought a 12" impulse sealer on ebay without looking into them too much "like oh hey this looks convienent no messing around w wires zip ties etc"haha
http://m.ebay.com/itm/271579712056?cmd=VIDESC
The impulse sealers on most supply sites are pretty much the same dimensions except theyre like 150 bux and seal a thicker mil?
I bought one of these for like 10 bux. Looks like it only seals to .3 mil
Do these cheaper sealers work on most spawn bags? If not it was only 10 bux but hey

I have a similar model as that one, it looks the exact same but a bit bigger, and mine works great for spawn bags. It goes from 0 (or 1?) up to.. I can't remember.. maybe 10. I find 4-4.5 to be the best spot. I haven't tried above 5 or maybe 6, but you begin the risk of melting/cutting the bag off so they're definitely strong enough if that's what you're worried about.

yea i think that will work. it might just be a weak model, and u will have to turn it up to 7. press medium hard during the seal, and then after the light goes off, keep it closed with ur hands for 4-5 seconds to let it cool and congeal before lifting, otherwise u can get pinholes because the plastic doesn't "set" right when u lift handle too quickly.
i dunno why it says its max heat time is 1.3 seconds. the numbers on the dial are supposed to correspond to the amount of seconds the element stays hot.

What did you get an impulse sealer for, mushpunx? You have a flowhood.

They do. Imo, an impulse sealers place in this hobby is for doing spawn bags modified with injection port to be inoculated in open-air though. Pre-sealing bags with an impulse seal greatly increases the risk of the bags bursting during sterilization creating a HUGE mess to clean up, as well as, all that time, effort, and materials used to prepare the substrate for sterilization in your sterilizer wasted.
With a flowhood you have the option of folding the bags accordion-style with the tyvek wrist sleeves installed for filtered air only to be allowed to enter the bags as they return to atmospheric pressure. More bags can be fit into the sterilizer at once using the aforementioned, accordion style method of sterilizing spawn bags, and with a flowhood, are easier to seal using tie wire or zip-ties.
You really can't go wrong with a ten dollar purchase either way, but I don't think it's going to work. It might though. Stranger things have happened. When considering purchasing an impulse sealer for use in this hobby specifically for sealing spawn bags, a good high-quality impulse sealer bigger than you think you are going to need should be purchased. I use to use an electric food-grade vacuum sealer to seal my bags, sealing the bags pre-sterilization cycle, only two at a time, sterilized at 15 psi for two hours, using presto23's as the sterilization vessel of choice, pre-flowhood days.

Ah, I gotcha. It sounded so convienent haha but yea really I'll just be cutting them open for G2G so maybe zip ties will work better.
Im sure ill find some awesome use for it haha
This is my first real switch over to bags, I gave them a try once before, melted them and made a mess. Im still picking plastic off my PC
But I bought a case of spawn bags off FP , gunna designate a bunch of quart jars for grain masters and going to retire the others, and use them for hundreds of stones jars

I think you'll be fine man. That's exactly what I use mine for, g2ging and then I seal them up in front of my flow hood. I also have a vacuum sealer that works, but I got the impulse sealer because I felt it would work better in front of the flow hood. I feel much safer throwing the bags around to break up the spawn with it sealed with an impulse sealer than I do with clothes pins, binder clips, zip ties, or whatever else. I've had some bags break in the pressure cooker, but from what I can tell it was always from melting as opposed to bursting.

So it came today, I dunno it looks pretty solid for ten bux. Ill do a couple test runs on an old bag, maybe fill it up with water, seal it up and test for leaks.
Although... I did my first couple spawn bags yesterday before it came and I gotta say, it was pretty easy to just twist up and zip tie, tie wire might even be better, this sealer might prove a bit clumbsy in front of the hood.
But since I have it I might as well use it right?

Let me know bro,
I want to get one and get into bags. Easier then jars. Then I want to dedicate all of my jars to a massive Sclerotia grow.

Hahaha thats what Im doing with my quarts too. Im saving a bunch to use as masters but I wamt to tie up the rest with stones grow
So the sealer.. I played around with the settings, took a piece of spawn bag and sealed one end, filled it with water and sealed the other side. Squeezed it alot, no leaks
You guys got me all paranoid about pinhole leaks haha, I dunno this sealer seems like it would work really nice with the flow hood, but so would tie wire which might be a bit more reliable
But it was cheap and it works

Seriously keep me posted on your bag progress, if I like the way it goes I'll be making the switch. Only thing I don't like about bags is they're one time use are they not? Or a few times but they do get old right?

Really only safe for one time use as the mycelium tends to slightly break down the plastic or at least degrade it.

See?
That's what gets me. My jars are infinite until I smash them. I just think bags would lead to shorter PC use. If I could fit 3 bags in my 23 qt presto that equal 15 jars I have just saved time. Then again if they're leaning against the side do the bags melt?

Haha well thats what this thread is about. I think you really just have to alter how you pack/use the PC if it isnt an AA.
It does seem wasteful, but when you think about it right now Im going 4 qts in one bag and then G2G half or a full quart master jar into it.
So one or half one jar-one bag- one tub
I bought a case of 100 bags to start with for around fifty bux, that should do 100 tubs so it seems fair, worth the cost of supplies IMO Oh and they take up less space, less lids you have to do etc. Ill finally be able to afford an SFD lid for every grain master haha
My first G2G with them was kinda clumbsy even working in front of the hood haha but I think a little practice and itll be cake

No. The bags will only melt if the PC runs out of water.

Keep a log man,
I will follow.

Even in my shitty 23 qt presto?
