thanks for the info massbaster.
i never used any tape, only a layer of tinfoil to cover the holes.
i'm still confused as to weather or not to remove the foil.
it seems like if i took the foil off and had to put tape over the holes that would defeat the purpose of removing the foil (letting mycelium breathe)
but leaving the holes exposed doesnt seem right to me.
ok first off, in the pf tek way the upper layer of vermiculite(plain) is to provide a barrier for airbourne particles. so logically after inoculating there should be no need to cover the holes as the verm should fill back in and keep things good. yes mycelium will have chance to breathe.
BUT the recipe states to cover the holes after inoculation.
i have left the holes covered on the first grow and things were fine.
i have them covered on this grow and things did not go so well for the first two weeks. little to no white nycelium growth.
on sept. 7th i started to give them more heat.(still taped) and since then the jars are mostly completed.
IN YOUR CASE, you used tin foil instead of tape to protect your inoculation holes from getting wet during sterilization.
even though you have that top layer of vermiculite, your needle will disturb it at the side of the jar. that could be a potential point of contamination IF the vermiculite does not completely fill back in after you remove the needle.
1.) i would leave the foil on and worry more about air exchange and CO2 when you have them in the fruiting chamber.
2.) you could remove the foil off one of them and see if there is an increase in speed of growth.
personally, i used tape and after sterilization and cooling took seven jars, un-taped the holes (with my nifty little pull tabs) of each jar, then inoculated. each time i came out of the hole i folded the tape back into place and sealed it.
tried to expose for the smallest amount of time after i removed the needle.
before the needle goes in the verm is the seal.
here is a recent pic. you can see the tabs. and seven days ago, there was no white. these jars are just at 18 days with 90% in the last 5-6 days.
