Mushroom growing bags advice

Hey! I was just wondering if anyone here has any experience with grow bags like this one?
https://micro-science.co.uk/product/mushroom-growing-bags-medium-injection-port/
I want to use grow bags as finding jars in the UK can be a bit of a pain + the website sells rye grain at a reasonable price too, so I might as well kill two birds with one stone.
I dont own a heat sealer (seems like a good future investment) but they sell clamps that they say can be attached before autoclaving. Does this mean that I can prepare the rye by soaking in hot water and all the other steps and then just add it to the bag, apply the clamp and just begin to sterilise as usual?
Also from experience do you think the clamp is effective at preventing contamination whilst in the inoculation stage?
Much appreciation for any replies and anything to point me in the right direction!
Thanks

colonizing substrates/spawn need gas exchange so you dont need to heal seal a spawn bag. just as long as the filter patch is not blocked ive used twist ties to seal a bag.
sponsors on this site have decent deals on all your spawn bag needs. just do not try to fruit in a spawn bag.

Ahhh sorry, my bad, I misread that ! Will it still be good enough to prevent contamination during inoculation too?

Those bags look pretty cool. The clamps are 1.95 euros a pop. kinda pricey and not necessary. You don't need an impulse sealer either. Here is a great Tek on how to use bags.

I cant begin to thank you for linking this to me! You've saved me so much time It should be relatively easy to do all of this now as inoculation will be simple because of the injection ports in the bag. I unforunately dont think I can get my hands on tyvek but im not too bothered about the price of the clamps. I think for the time being I will just use the tek as a guide when autoclaving. I've trialed a pre-sterilised rye bag and I'll post some pics of that soon Thanks for the help my G.

Make sure u can fit the clamps in ur PC
it's hard to zip tie those style bags because there is not as much head space above the filters as unicorn bags, just FYI
