@legalcanada any syringe will do just remember to have enough ccs of solution to do all your jars.. I use a 10ml syringe with a 20g needle and it's been fine for a long time.. I change needles occasionally but you dont really need to..
@MadScientist and everyone else reading
cakes to fruit
once the mycelium starts growing it will reach out and feed and grow to find compatible mycelium to create a network of nutrient harvesting fungus.. or the start anyway..
once the jar is completely colonized visibly (whole jar will be white all around with mycelium growth.. no substrate showing) give it 3 to 5 more days to complete it's hold on the middle of the cake which you can't see and might not be fully colonized. this is called consolidation.
when they are ready, take the foil off turn them upside down and tap them into your hand and... WAIT WAIT WAIT!!!!
what are we gonna do with them after?
well you'll need a sterilite tote from somewhere.. clear plastic even the lid.. it needs to be big enough to hold all your cakes with a couple inches in between..
now comes the "fun" part.. Mark one hole every two inches on ALL six sides of the tub and drill them out..
or dont.. but they rely on oxygen to live.. not co2.. they are fungus..not plants.. the breathe in on oxygen and expel co2..
I don't do all the holes though.. I will say that.. i usually make a equalateral triangle on the long sides and an upside down smaller triangle on the sides and scatter maybe 15 holes on the top and bottom.. co2 sinks and gets caught in the perlite.. bottom holes are more co2 sink outs..
put your perlite in the fruiting chamber til ther es 4 or 5 inches in the bottom of it.. it's fine if its covering holes.. remember co2 sinks..pour a bit of water into the perlite.. usually a bottle or two of water depending on size of tub and amount of perlite and mix it around getting it hydrated.. flatten the surface out..
when you birth your cakes into this world.. you want to take them and fully submerge them in room temp water overnight or around 12 hours.. gives them more water content.. and you don't want dry cakes in the middle..when they are done soaking get a bowl and fill it with some more vermicullite and roll your cakes in it and cover the sides too and bottom.. these help retain moisture and create little micro climates on the surface perfect for growing..
get enough little squares of foil to sit all your cakes on and put them on it..now.. you'll need a spray bottle that basically mists.. like a cheap one from the store works.. you dont want to ever mist them directly.. stresses the mycelium out and bruises it and water on the surface that's pooling isn't good.. you want them to glisten..
then take the lid and use it like a fan and gently fan them every 8 hours or so.. most even less often.. youbarent misting them for them to drink.. the dont.. you're misting to cause a damp surface to evaporate it's water and cause tye mycelium to think of death and saving it's genetics.. evaporation is the number 1 and only pinning trigger in cubes.. you are trying to create a tropical humid environment and make it's water put itself in the air..
12/12 light cycle but it isn't needed.. just helps maintain humidity.. mushrooms aren't phototropic.. they dont need light to survive, just to know what way to grow.
