Right after I inject a jar, do I need to... 1

Right after I inject a jar, do I need to cover it with foil again? I'm working in an SAB, pf tek with six half pint BRF jars. So remove foil, inject, put it aside in the box and do the others? Or should I re-cover with the foil that just came off? Or is that a contam risk? Or am I splitting hairs?
All the jars have a half inch fine verm barrier at the top.
Thx as always

I would recover or finish them however, any time it's uncovered there is a 'Risk'

The dry verm layer provides the filter so you don’t need to put the foil back on. Make sure the needle goes all the way through the dry verm in to the substrate before injecting though.

I like to reapply the foil cover, just to be safe and to make the SAB more tiddy. Also I pitch the top of the foil so I know which jars Ive already injected.

Your dry verm barrier protects from contaminates / allows gas exchange.
If your using a SAB you could have used micropore tape or Sfd's on top of the holes, unscrew lid inject and screw tight again easy. Means you fit abit extra brf mix into each jar and no messing around with dry vermiculite.
Stick to the tek though you'll get the fruits you want and experiment next time.

Leave the jars uncovered.

I’m guessing you are doing the two layers of foil method? If so, the first layer stays on, the one that you have put the syringe through. The 2nd layer, top, goes in the trash. Keeping the syringe holes uncovered provides gas exchange and in my experience speeds up consolidation.

What is the two layer foil method?
Foil cover during PC or Steam Bath Cycle and then take them off, that is all that is needed. Foil will act as a way to prevent gas exchange and also trap moisture at the top of the jar keeping your dry filter vermiculite layer wet.

I saw it in a cultivation book, 2 layers of foil, boil the jars, take the top layer of foil off and puncture the 2nd layer of foil with the syringe, the book said to put the 1st layer of foil back on. Reading through these forums, it doesn’t make sense to put the foil back on.

If your using jars without lids such as drinking glasses.
